Common Styles

By default, a GUI window uses WS_POPUP, WS_CAPTION, WS_SYSMENU, and WS_MINIMIZEBOX. For a GUI window, WS_CLIPSIBLINGS is always enabled and cannot be disabled.

Style Hex Description
WS_BORDER 0x800000 +/-Border. Creates a window that has a thin-line border.
WS_POPUP 0x80000000 Creates a pop-up window. This style cannot be used with the WS_CHILD style.
WS_CAPTION 0xC00000 +/-Caption. Creates a window that has a title bar. This style is a numerical combination of WS_BORDER and WS_DLGFRAME.
WS_CLIPSIBLINGS 0x4000000 Clips child windows relative to each other; that is, when a particular child window receives a WM_PAINT message, the WS_CLIPSIBLINGS style clips all other overlapping child windows out of the region of the child window to be updated. If WS_CLIPSIBLINGS is not specified and child windows overlap, it is possible, when drawing within the client area of a child window, to draw within the client area of a neighboring child window.
WS_DISABLED 0x8000000 +/-Disabled. Creates a window that is initially disabled.
WS_DLGFRAME 0x400000 Creates a window that has a border of a style typically used with dialog boxes.
WS_GROUP 0x20000 +/-Group. Indicates that this control is the first one in a group of controls. This style is automatically applied to manage the "only one at a time" behavior of radio buttons. In the rare case where two groups of radio buttons are added consecutively (with no other control types in between them), this style may be applied manually to the first control of the second radio group, which splits it off from the first.
WS_HSCROLL 0x100000 Creates a window that has a horizontal scroll bar.
WS_MAXIMIZE 0x1000000 Creates a window that is initially maximized.
WS_MAXIMIZEBOX 0x10000 +/-MaximizeBox. Creates a window that has a maximize button. Cannot be combined with the WS_EX_CONTEXTHELP style. The WS_SYSMENU style must also be specified.
WS_MINIMIZE 0x20000000 Creates a window that is initially minimized.
WS_MINIMIZEBOX 0x20000 +/-MinimizeBox. Creates a window that has a minimize button. Cannot be combined with the WS_EX_CONTEXTHELP style. The WS_SYSMENU style must also be specified.

WS_OVERLAPPEDWINDOW 0xCF0000 Creates an overlapped window with the WS_OVERLAPPED, WS_CAPTION, WS_SYSMENU, WS_THICKFRAME, WS_MINIMIZEBOX, and WS_MAXIMIZEBOX styles. Same as the WS_TILEDWINDOW style.
WS_POPUPWINDOW 0x80880000 Creates a pop-up window with WS_BORDER, WS_POPUP, and WS_SYSMENU styles. The WS_CAPTION and WS_POPUPWINDOW styles must be combined to make the window menu visible.
WS_SIZEBOX 0x40000 +/-Resize. Creates a window that has a sizing border. Same as the WS_THICKFRAME style.

WS_TABSTOP 0x10000 +/-Tabstop. Specifies a control that can receive the keyboard focus when the user presses Tab. Pressing Tab changes the keyboard focus to the next control with the WS_TABSTOP style.
WS_THICKFRAME 0x40000 Creates a window that has a sizing border. Same as the WS_SIZEBOX style.
WS_VSCROLL 0x200000 Creates a window that has a vertical scroll bar.

Text Control Styles

These styles affect the Text control. It has neither default styles nor forced styles.

Style Hex Description
SS_BLACKFRAME 0x7 Specifies a box with a frame drawn in the same color as the window frames. This color is black in the default color scheme.
SS_BLACKRECT 0x4 Specifies a rectangle filled with the current window frame color. This color is black in the default color scheme.
SS_CENTER 0x1 +/-Center. Specifies a simple rectangle and centers the text in the rectangle. The control automatically wraps words that extend past the end of a line to the beginning of the next centered line.

SS_ETCHEDVERT 0x11 Draws the left and right edges of the static control using the EDGE_ETCHED edge style.
SS_GRAYFRAME 0x8 Specifies a box with a frame drawn with the same color as the screen background (desktop). This color is gray in the default color scheme.
SS_GRAYRECT 0x5 Specifies a rectangle filled with the current screen background color. This color is gray in the default color scheme.
SS_LEFT 0x0 +/-Left. This is the default. It specifies a simple rectangle and left-aligns the text in the rectangle. The text is formatted before it is displayed. Words that extend past the end of a line are automatically wrapped to the beginning of the next left-aligned line. Words that are longer than the width of the control are truncated.
SS_LEFTNOWORDWRAP 0xC +/-Wrap. Specifies a rectangle and left-aligns the text in the rectangle. Tabs are expanded, but words are not wrapped. Text that extends past the end of a line is clipped.
SS_NOPREFIX 0x80 Prevents interpretation of any ampersand (&) characters in the control's text as accelerator prefix characters. This can be useful when file names or other strings that might contain an ampersand (&) must be displayed within a text control.

SS_WHITERECT 0x6 Specifies a rectangle filled with the current window background color. This color is white in the default color scheme.

Edit Control Styles

These styles affect the Edit control. By default, it uses WS_TABSTOP and WS_EX_CLIENTEDGE (extended style E0x200). It has no forced styles.

If an Edit control is auto-detected as multi-line due to its starting contents containing multiple lines, its height being taller than 1 row, or its row-count having been explicitly specified as greater than 1, the following styles will be applied by default: WS_VSCROLL, ES_WANTRETURN, and ES_AUTOVSCROLL.

If an Edit control is auto-detected as a single line, it defaults to having ES_AUTOHSCROLL.

Style Hex Description
ES_AUTOHSCROLL 0x80 +/-Wrap for multi-line edits, and +/-Limit for single-line edits. Automatically scrolls text to the right by 10 characters when the user types a character at the end of the line. When the user presses Enter, the control scrolls all text back to the zero position.
ES_AUTOVSCROLL 0x40 Scrolls text up one page when the user presses Enter on the last line.
ES_CENTER 0x1 +/-Center. Centers text in a multiline edit control.
ES_LOWERCASE 0x10 +/-Lowercase. Converts all characters to lowercase as they are typed into the edit control.
ES_NOHIDESEL 0x100 Negates the default behavior for an edit control. The default behavior hides the selection when the control loses the input focus and inverts the selection when the control receives the input focus. If you specify ES_NOHIDESEL, the selected text is inverted, even if the control does not have the focus.
ES_NUMBER 0x2000 +/-Number. Prevents the user from typing anything other than digits in the control.
ES_OEMCONVERT 0x400 This style is most useful for edit controls that contain file names.
ES_MULTILINE 0x4 +/-Multi. Designates a multiline edit control. The default is a single-line edit control.
ES_PASSWORD 0x20 +/-Password. Displays a masking character in place of each character that is typed into the edit control, which conceals the text.
ES_READONLY 0x800 +/-ReadOnly. Prevents the user from typing or editing text in the edit control.
ES_RIGHT 0x2 +/-Right. Right-aligns text in a multiline edit control.
ES_UPPERCASE 0x8 +/-Uppercase. Converts all characters to uppercase as they are typed into the edit control.
ES_WANTRETURN 0x1000 +/-WantReturn. Specifies that a carriage return be inserted when the user presses Enter while typing text into a multiline edit control in a dialog box. If you do not specify this style, pressing Enter has the same effect as pressing the dialog box's default push button. This style has no effect on a single-line edit control.

UpDown Control Styles

These styles affect the UpDown control. By default, it uses UDS_ARROWKEYS, UDS_ALIGNRIGHT, UDS_SETBUDDYINT, and UDS_AUTOBUDDY. It has no forced styles.

Style Hex Description
UDS_WRAP 0x1 Named option "Wrap". Causes the control to wrap around to the other end of its range when the user attempts to go beyond the minimum or maximum. Without Wrap, the control stops when the minimum or maximum is reached.
UDS_SETBUDDYINT 0x2 Causes the UpDown control to set the text of the buddy control (using the WM_SETTEXT message) when the position changes. However, if the buddy is a ListBox, the ListBox's current selection is changed instead.
UDS_ALIGNRIGHT 0x4 Named option "Right" (default). Positions UpDown on the right side of its buddy control.
UDS_ALIGNLEFT 0x8 Named option "Left". Positions UpDown on the left side of its buddy control.
UDS_AUTOBUDDY 0x10 Automatically selects the previous control in the z-order as the UpDown control's buddy control.
UDS_ARROWKEYS 0x20 Allows the user to press or on the keyboard to increase or decrease the UpDown control's position.
UDS_HORZ 0x40 Named option "Horz". Causes the control's arrows to point left and right instead of up and down.
UDS_NOTHOUSANDS 0x80 Does not insert a thousands separator between every three decimal digits in the buddy control.
UDS_HOTTRACK 0x100 Causes the control to exhibit "hot tracking" behavior. That is, it highlights the control's buttons as the mouse passes over them. This flag may be ignored if the desktop theme overrides it.

Picture Control Styles

These styles affect the Picture control. It has no default styles. The style SS_ICON (for icons and cursors) or SS_BITMAP (for other image types) is always enabled and cannot be disabled.

Style Hex Description
SS_REALSIZECONTROL 0x40 Adjusts the bitmap to fit the size of the control.
SS_CENTERIMAGE 0x200

Centers the bitmap in the control. If the bitmap is too large, it will be clipped. For text controls, if the control contains a single line of text, the text is centered vertically within the available height of the control.

Button, CheckBox, Radio, and GroupBox Control Styles

These styles affect the Button, CheckBox, Radio, or GroupBox controls.

By default, each of these controls except GroupBox uses the styles BS_MULTILINE (unless it has no explicitly set width or height, nor any CR/LF characters in their text) and WS_TABSTOP (however, Radio controls other than the first of each radio group lack WS_TABSTOP). In addition, Radio controls have BS_NOTIFY so that double clicks can be detected.

The following styles are always enabled and cannot be disabled:

Style Hex Description
BS_AUTO3STATE 0x6 Creates a button that is the same as a three-state check box, except that the box changes its state when the user selects it. The state cycles through checked, indeterminate, and cleared.
BS_AUTOCHECKBOX 0x3 Creates a button that is the same as a check box, except that the check state automatically toggles between checked and cleared each time the user selects the check box.
BS_AUTORADIOBUTTON 0x9 Creates a button that is the same as a radio button, except that when the user selects it, the system automatically sets the button's check state to checked and automatically sets the check state for all other buttons in the same group to cleared.
BS_LEFT 0x100 +/-Left. Left-aligns the text.
BS_PUSHBUTTON 0x0 Creates a push button that posts a WM_COMMAND message to the owner window when the user selects the button.
BS_PUSHLIKE 0x1000 Makes a checkbox or radio button look and act like a push button. The button looks raised when it isn't pushed or checked, and sunken when it is pushed or checked.
BS_RIGHT 0x200 +/-Right. Right-aligns the text.
BS_RIGHTBUTTON 0x20 +Right (i.e. +Right includes both BS_RIGHT and BS_RIGHTBUTTON, but -Right removes only BS_RIGHT, not BS_RIGHTBUTTON). Positions a checkbox square or radio button circle on the right side of the control's available width instead of the left.
BS_BOTTOM 0x800 Places the text at the bottom of the control's available height.
BS_CENTER 0x300 +/-Center. Centers the text horizontally within the control's available width.
BS_DEFPUSHBUTTON 0x1 +/-Default. Creates a push button with a heavy black border. If the button is in a dialog box, the user can select the button by pressing Enter, even when the button does not have the input focus. This style is useful for enabling the user to quickly select the most likely option.
BS_MULTILINE 0x2000 +/-Wrap. Wraps the text to multiple lines if the text is too long to fit on a single line in the control's available width. This also allows linefeed (`n) to start new lines of text.
BS_NOTIFY 0x4000 Enables a button to send BN_KILLFOCUS and BN_SETFOCUS notification codes to its parent window. Note that buttons send the BN_CLICKED notification code regardless of whether it has this style. To get BN_DBLCLK notification codes, the button must have the BS_RADIOBUTTON or BS_OWNERDRAW style.
BS_TOP 0x400 Places text at the top of the control's available height.
BS_VCENTER 0xC00 Vertically centers text in the control's available height.
BS_FLAT 0x8000 Specifies that the button is two-dimensional; it does not use the default shading to create a 3-D effect.
BS_GROUPBOX 0x7 Creates a rectangle in which other controls can be grouped. Any text associated with this style is displayed in the rectangle's upper left corner.

DropDownList and ComboBox Control Styles

These styles affect the DropDownList and ComboBox controls.

By default, each of these controls uses WS_TABSTOP. In addition, a DropDownList control uses WS_VSCROLL, and a ComboBox control uses WS_VSCROLL and CBS_AUTOHSCROLL.

The following styles are always enabled and cannot be disabled:

Style Hex Description
CBS_AUTOHSCROLL 0x40 +/-Limit. Automatically scrolls the text in an edit control to the right when the user types a character at the end of the line. If this style is not set, only text that fits within the rectangular boundary is enabled.
CBS_DISABLENOSCROLL 0x800 Shows a disabled vertical scroll bar in the drop-down list when it does not contain enough items to scroll. Without this style, the scroll bar is hidden when the drop-down list does not contain enough items.
CBS_DROPDOWN 0x2 Similar to CBS_SIMPLE, except that the list box is not displayed unless the user selects an icon next to the edit control.
CBS_DROPDOWNLIST 0x3 Similar to CBS_DROPDOWN, except that the edit control is replaced by a static text item that displays the current selection in the list box.
CBS_LOWERCASE 0x4000 +/-Lowercase. Converts to lowercase any uppercase characters that are typed into the edit control of a combo box.
CBS_NOINTEGRALHEIGHT 0x400 Specifies that the combo box will be exactly the size specified by the application when it created the combo box. Usually, Windows CE sizes a combo box so that it does not display partial items.
CBS_OEMCONVERT 0x80 Converts text typed in the combo box edit control from the Windows CE character set to the OEM character set and then back to the Windows CE set. This style is most useful for combo boxes that contain file names. It applies only to combo boxes created with the CBS_DROPDOWN style.
CBS_SIMPLE 0x1 +/-Simple (ComboBox only). Displays the drop-down list at all times. The current selection in the list is displayed in the edit control.
CBS_SORT 0x100 +/-Sort. Sorts the items in the drop-list alphabetically.
CBS_UPPERCASE 0x2000 +/-Uppercase. Converts to uppercase any lowercase characters that are typed into the edit control of a ComboBox.

ListBox Control Styles

These styles affect the ListBox control. By default, it uses WS_TABSTOP, LBS_USETABSTOPS, WS_VSCROLL, and WS_EX_CLIENTEDGE (extended style E0x200). The style LBS_NOTIFY (supports detection of double-clicks) is always enabled and cannot be disabled.

Style Hex Description
LBS_DISABLENOSCROLL 0x1000 Shows a disabled vertical scroll bar for the list box when the box does not contain enough items to scroll. If you do not specify this style, the scroll bar is hidden when the list box does not contain enough items.
LBS_NOINTEGRALHEIGHT 0x100 Specifies that the list box will be exactly the size specified by the application when it created the list box.
LBS_EXTENDEDSEL 0x800 +/-Multi. Allows multiple selections via control-click and shift-click.
LBS_MULTIPLESEL 0x8 A simplified version of multi-select in which control-click and shift-click are not necessary because normal left clicks serve to extend the selection or de-select a selected item.
LBS_NOSEL 0x4000 +/-ReadOnly. Specifies that the user can view list box strings but cannot select them.
LBS_NOTIFY 0x1 Causes the list box to send a notification code to the parent window whenever the user clicks a list box item (LBN_SELCHANGE), double-clicks an item (LBN_DBLCLK), or cancels the selection (LBN_SELCANCEL).
LBS_SORT 0x2 +/-Sort. Sorts the items in the list box alphabetically.
LBS_USETABSTOPS 0x80 Enables a ListBox to recognize and expand tab characters when drawing its strings. The default tab positions are 32 dialog box units apart. A dialog box unit is equal to one-fourth of the current dialog box base-width unit.

ListView Control Styles

These styles affect the ListView control. By default, it uses WS_TABSTOP, LVS_REPORT, LVS_SHOWSELALWAYS, LVS_EX_FULLROWSELECT, LVS_EX_HEADERDRAGDROP, and WS_EX_CLIENTEDGE (extended style E0x200). It has no forced styles.

Style Hex Description
LVS_ALIGNLEFT 0x800 Items are left-aligned in icon and small icon view.
LVS_ALIGNTOP 0x0 Items are aligned with the top of the list-view control in icon and small icon view. This is the default.
LVS_AUTOARRANGE 0x100 Icons are automatically kept arranged in icon and small icon view.
LVS_EDITLABELS 0x200 +/-ReadOnly. Specifying -ReadOnly (or +0x200) allows the user to edit the first field of each row in place.
LVS_ICON 0x0 +Icon. Specifies large-icon view.
LVS_LIST 0x3 +List. Specifies list view.
LVS_NOCOLUMNHEADER 0x4000 +/-Hdr. Avoids displaying column headers in report view.
LVS_NOLABELWRAP 0x80 Item text is displayed on a single line in icon view. By default, item text may wrap in icon view.
LVS_NOSCROLL 0x2000 Scrolling is disabled. All items must be within the client area. This style is not compatible with the LVS_LIST or LVS_REPORT styles.
LVS_NOSORTHEADER 0x8000 +/-NoSortHdr. Column headers do not work like buttons. This style can be used if clicking a column header in report view does not carry out an action, such as sorting.
LVS_OWNERDATA 0x1000 This style specifies a virtual list-view control (not directly supported by AutoHotkey).
LVS_OWNERDRAWFIXED 0x400 The owner window can paint items in report view in response to WM_DRAWITEM messages (not directly supported by AutoHotkey).
LVS_REPORT 0x1 +Report. Specifies report view.

LVS_SORTDESCENDING 0x20 +/-SortDesc. Same as above but in descending order.

Extended ListView styles require the LV prefix when used with the Gui methods/properties. Some extended styles introduced in Windows XP or later versions are not listed here. For a full list, see MSDN: Extended List-View Styles.

Extended Style Hex Description
LVS_EX_BORDERSELECT LV0x8000 When an item is selected, the border color of the item changes rather than the item being highlighted (might be non-functional in recent operating systems).
LVS_EX_CHECKBOXES LV0x4

+/-Checked. Displays a checkbox with each item. When set to this style, the control creates and sets a state image list with two images using DrawFrameControl. State image 1 is the unchecked box, and state image 2 is the checked box. Setting the state image to zero removes the check box altogether.

Checkboxes are visible and functional with all list-view modes except the tile view mode. Clicking a checkbox in tile view mode only selects the item; the state does not change.

LVS_EX_DOUBLEBUFFER LV0x10000

Paints via double-buffering, which reduces flicker. This extended style also enables alpha-blended marquee selection on systems where it is supported.

LVS_EX_FLATSB LV0x100 Enables flat scroll bars in the list view.
LVS_EX_FULLROWSELECT LV0x20 When a row is selected, all its fields are highlighted. This style is available only in conjunction with the LVS_REPORT style.
LVS_EX_GRIDLINES LV0x1 +/-Grid. Displays gridlines around rows and columns. This style is available only in conjunction with the LVS_REPORT style.
LVS_EX_HEADERDRAGDROP LV0x10 Enables drag-and-drop reordering of columns in a list-view control. This style is only available to list-view controls that use the LVS_REPORT style.
LVS_EX_INFOTIP LV0x400 When a list-view control uses this style, the LVN_GETINFOTIP notification message is sent to the parent window before displaying an item's ToolTip.
LVS_EX_LABELTIP LV0x4000 If a partially hidden label in any list-view mode lacks ToolTip text, the list-view control will unfold the label. If this style is not set, the list-view control will unfold partly hidden labels only for the large icon mode. Note: On some versions of Windows, this style might not work properly if the GUI window is set to be always-on-top.
LVS_EX_MULTIWORKAREAS LV0x2000 If the list-view control has the LVS_AUTOARRANGE style, the control will not autoarrange its icons until one or more work areas are defined (see LVM_SETWORKAREAS). To be effective, this style must be set before any work areas are defined and any items have been added to the control.
LVS_EX_ONECLICKACTIVATE LV0x40 The list-view control sends an LVN_ITEMACTIVATE notification message to the parent window when the user clicks an item. This style also enables hot tracking in the list-view control. Hot tracking means that when the cursor moves over an item, it is highlighted but not selected.
LVS_EX_REGIONAL LV0x200 Sets the list-view window region to include only the item icons and text using SetWindowRgn. Any area that is not part of an item is excluded from the window region. This style is only available to list-view controls that use the LVS_ICON style.
LVS_EX_SIMPLESELECT LV0x100000 In icon view, moves the state image of the item to the top right of the large icon rendering. In views other than icon view there is no change. When the user changes the state by using the space bar, all selected items cycle over, not the item with the focus.
LVS_EX_SUBITEMIMAGES LV0x2 Allows images to be displayed for fields beyond the first. This style is available only in conjunction with the LVS_REPORT style.
LVS_EX_TRACKSELECT LV0x8 Enables hot-track selection in a list-view control. Hot track selection means that an item is automatically selected when the cursor remains over the item for a certain period of time. The delay can be changed from the default system setting with a LVM_SETHOVERTIME message. This style applies to all styles of list-view control. You can check whether hot-track selection is enabled by calling SystemParametersInfo.
LVS_EX_TWOCLICKACTIVATE LV0x80 The list-view control sends an LVN_ITEMACTIVATE notification message to the parent window when the user double-clicks an item. This style also enables hot tracking in the list-view control. Hot tracking means that when the cursor moves over an item, it is highlighted but not selected.
LVS_EX_UNDERLINECOLD LV0x1000 Causes those non-hot items that may be activated to be displayed with underlined text. This style requires that LVS_EX_TWOCLICKACTIVATE be set also.
LVS_EX_UNDERLINEHOT LV0x800 Causes those hot items that may be activated to be displayed with underlined text. This style requires that LVS_EX_ONECLICKACTIVATE or LVS_EX_TWOCLICKACTIVATE also be set.

TreeView Control Styles

These styles affect the TreeView control. By default, it uses WS_TABSTOP, TVS_SHOWSELALWAYS, TVS_HASLINES, TVS_LINESATROOT, TVS_HASBUTTONS, and WS_EX_CLIENTEDGE (extended style E0x200). It has no forced styles.

Style Hex Description
TVS_CHECKBOXES 0x100 +/-Checked. Displays a checkbox next to each item.
TVS_DISABLEDRAGDROP 0x10 Prevents the tree-view control from sending TVN_BEGINDRAG notification messages.
TVS_EDITLABELS 0x8 +/-ReadOnly. Allows the user to edit the names of tree-view items.
TVS_FULLROWSELECT 0x1000 Enables full-row selection in the tree view. The entire row of the selected item is highlighted, and clicking anywhere on an item's row causes it to be selected. This style cannot be used in conjunction with the TVS_HASLINES style.
TVS_HASBUTTONS 0x1 +/-Buttons. Displays plus (+) and minus (-) buttons next to parent items. The user clicks the buttons to expand or collapse a parent item's list of child items. To include buttons with items at the root of the tree view, TVS_LINESATROOT must also be specified.
TVS_HASLINES 0x2 +/-Lines. Uses lines to show the hierarchy of items.
TVS_INFOTIP 0x800 Obtains ToolTip information by sending the TVN_GETINFOTIP notification.
TVS_LINESATROOT 0x4 +/-Lines. Uses lines to link items at the root of the tree-view control. This value is ignored if TVS_HASLINES is not also specified.
TVS_NOHSCROLL 0x8000 +/-HScroll. Disables horizontal scrolling in the control. The control will not display any horizontal scroll bars.
TVS_NONEVENHEIGHT 0x4000 Sets the height of the items to an odd height with the TVM_SETITEMHEIGHT message. By default, the height of items must be an even value.
TVS_NOSCROLL 0x2000 Disables both horizontal and vertical scrolling in the control. The control will not display any scroll bars.
TVS_NOTOOLTIPS 0x80 Disables tooltips.
TVS_RTLREADING 0x40 Causes text to be displayed from right-to-left (RTL). Usually, windows display text left-to-right (LTR).
TVS_SHOWSELALWAYS 0x20 Causes a selected item to remain selected when the tree-view control loses focus.
TVS_SINGLEEXPAND 0x400 Causes the item being selected to expand and the item being unselected to collapse upon selection in the tree-view. If the user holds down Ctrl while selecting an item, the item being unselected will not be collapsed.
TVS_TRACKSELECT 0x200 Enables hot tracking of the mouse in a tree-view control.

DateTime Control Styles

These styles affect the DateTime control. By default, it uses DTS_SHORTDATECENTURYFORMAT and WS_TABSTOP. It has no forced styles.

Style Hex Description
DTS_UPDOWN 0x1 Provides an up-down control to the right of the control to modify date-time values, which replaces the of the drop-down month calendar that would otherwise be available.
DTS_SHOWNONE 0x2 Displays a checkbox inside the control that users can uncheck to make the control have no date/time selected. Whenever the control has no date/time, Gui.Submit and GuiCtrl.Value will retrieve a blank value (empty string).
DTS_SHORTDATEFORMAT 0x0 Displays the date in short format. In some locales, it looks like 6/1/05 or 6/1/2005. On older operating systems, a two-digit year might be displayed. This is why DTS_SHORTDATECENTURYFORMAT is the default and not DTS_SHORTDATEFORMAT.
DTS_LONGDATEFORMAT 0x4 Format option "LongDate". Displays the date in long format. In some locales, it looks like Wednesday, June 01, 2005.
DTS_SHORTDATECENTURYFORMAT 0xC Format option blank/omitted. Displays the date in short format with four-digit year. In some locales, it looks like 6/1/2005. If the system's version of Comctl32.dll is older than 5.8, this style is not supported and DTS_SHORTDATEFORMAT is automatically substituted.
DTS_TIMEFORMAT 0x9 Format option "Time". Displays only the time, which in some locales looks like 5:31:42 PM.
DTS_APPCANPARSE 0x10 Not yet supported. Allows the owner to parse user input and take necessary action. It enables users to edit within the client area of the control when they press F2. The control sends DTN_USERSTRING notification messages when users are finished.
DTS_RIGHTALIGN 0x20 +/-Right. The calendar will drop down on the right side of the control instead of the left.

MonthCal Control Styles

These styles affect the MonthCal control. By default, it uses WS_TABSTOP. It has no forced styles.

Style Hex Description
MCS_DAYSTATE 0x1 Makes the control send MCN_GETDAYSTATE notifications to request information about which days should be displayed in bold. [Not yet supported]
MCS_MULTISELECT 0x2

Named option "Multi". Allows the user to select a range of dates rather than being limited to a single date. By default, the maximum range is 366 days, which can be changed by sending the MCM_SETMAXSELCOUNT message to the control. For example:

SendMessage 0x1004, 7, 0, "SysMonthCal321", MyGui ; 7 days. 0x1004 is MCM_SETMAXSELCOUNT.
MCS_WEEKNUMBERS 0x4 Displays week numbers (1-52) to the left of each row of days. Week 1 is defined as the first week that contains at least four days.
MCS_NOTODAYCIRCLE 0x8 Prevents the circling of today's date within the control.
MCS_NOTODAY 0x10 Prevents the display of today's date at the bottom of the control.

Slider Control Styles

These styles affect the Slider control. By default, it uses WS_TABSTOP. It has no forced styles.

Style Hex Description
TBS_VERT 0x2 +/-Vertical. The control is oriented vertically.
TBS_LEFT 0x4 +/-Left. The control displays tick marks at the top of the control (or to its left if TBS_VERT is present). Same as TBS_TOP.
TBS_TOP 0x4 same as TBS_LEFT.
TBS_BOTH 0x8 +/-Center. The control displays tick marks on both sides of the control. This will be both top and bottom when used with TBS_HORZ or both left and right if used with TBS_VERT.
TBS_AUTOTICKS 0x1 The control has a tick mark for each increment in its range of values. Use +/-TickInterval to have more flexibility.
TBS_ENABLESELRANGE 0x20

The control displays a selection range only. The tick marks at the starting and ending positions of a selection range are displayed as triangles (instead of vertical dashes), and the selection range is highlighted (highlighting might require that the theme be removed via GuiObj.Opt("-Theme")).

To set the selection range, follow this example, which sets the starting position to 55 and the ending position to 66:

SendMessage 0x040B, 1, 55, "msctls_trackbar321", WinTitle
SendMessage 0x040C, 1, 66, "msctls_trackbar321", WinTitle
TBS_FIXEDLENGTH 0x40 +/-Thick. Allows the thumb's size to be changed.
TBS_NOTHUMB 0x80 The control does not display the moveable bar.
TBS_NOTICKS 0x10 +/-NoTicks. The control does not display any tick marks.
TBS_TOOLTIPS 0x100 +/-ToolTip. The control supports tooltips. When a control is created using this style, it automatically creates a default ToolTip control that displays the slider's current position. You can change where the tooltips are displayed by using the TBM_SETTIPSIDE message.
TBS_REVERSED 0x200 Unfortunately, this style has no effect on the actual behavior of the control, so there is probably no point in using it (instead, use +Invert in the control's options to reverse it). Depending on OS version, this style might require Internet Explorer 5.0 or greater.
TBS_DOWNISLEFT 0x400 Unfortunately, this style has no effect on the actual behavior of the control, so there is probably no point in using it. Depending on OS version, this style might require Internet Explorer 5.01 or greater.

Progress Control Styles

These styles affect the Progress control. By default, it uses PBS_SMOOTH. It has no forced styles.

Style Hex Description
PBS_SMOOTH 0x1 +/-Smooth. The progress bar displays progress status in a smooth scrolling bar instead of the default segmented bar. When this style is present, the control automatically reverts to the Classic Theme appearance.
PBS_VERTICAL 0x4 +/-Vertical. The progress bar displays progress status vertically, from bottom to top.
PBS_MARQUEE 0x8

The progress bar moves like a marquee; that is, each change to its position causes the bar to slide further along its available length until it wraps around to the other side. A bar with this style has no defined position. Each attempt to change its position will instead slide the bar by one increment.

This style is typically used to indicate an ongoing operation whose completion time is unknown.

Tab Control Styles

These styles affect the Tab control. By default, it uses WS_TABSTOP and TCS_MULTILINE. The style WS_CLIPSIBLINGS is always enabled and cannot be disabled, while TCS_OWNERDRAWFIXED is forced on or off as required by the control's background color and/or text color.

Style Hex Description
TCS_SCROLLOPPOSITE 0x1 Unneeded tabs scroll to the opposite side of the control when a tab is selected.
TCS_BOTTOM 0x2 +/-Bottom. Tabs appear at the bottom of the control instead of the top.
TCS_RIGHT 0x2 Tabs appear vertically on the right side of controls that use the TCS_VERTICAL style.
TCS_MULTISELECT 0x4 Multiple tabs can be selected by holding down Ctrl when clicking. This style must be used with the TCS_BUTTONS style.
TCS_FLATBUTTONS 0x8 Selected tabs appear as being indented into the background while other tabs appear as being on the same plane as the background. This style only affects tab controls with the TCS_BUTTONS style.
TCS_FORCEICONLEFT 0x10 Icons are aligned with the left edge of each fixed-width tab. This style can only be used with the TCS_FIXEDWIDTH style.
TCS_FORCELABELLEFT 0x20

Labels are aligned with the left edge of each fixed-width tab; that is, the label is displayed immediately to the right of the icon instead of being centered.

This style can only be used with the TCS_FIXEDWIDTH style, and it implies the TCS_FORCEICONLEFT style.

TCS_HOTTRACK 0x40 Items under the pointer are automatically highlighted.
TCS_VERTICAL 0x80

+/-Left or +/-Right. Tabs appear at the left side of the control, with tab text displayed vertically. This style is valid only when used with the TCS_MULTILINE style. To make tabs appear on the right side of the control, also use the TCS_RIGHT style.

This style will not correctly display the tabs if a custom background color or text color is in effect. To workaround this, specify -Background and/or cDefault in the tab control's options.

TCS_BUTTONS 0x100 +/-Buttons. Tabs appear as buttons, and no border is drawn around the display area.
TCS_SINGLELINE 0x0 +/-Wrap. Only one row of tabs is displayed. The user can scroll to see more tabs, if necessary. This style is the default.
TCS_MULTILINE 0x200 +/-Wrap. Multiple rows of tabs are displayed, if necessary, so all tabs are visible at once.
TCS_RIGHTJUSTIFY 0x0

This is the default. The width of each tab is increased, if necessary, so that each row of tabs fills the entire width of the tab control.

This window style is ignored unless the TCS_MULTILINE style is also specified.

TCS_FIXEDWIDTH 0x400 All tabs are the same width. This style cannot be combined with the TCS_RIGHTJUSTIFY style.
TCS_RAGGEDRIGHT 0x800 Rows of tabs will not be stretched to fill the entire width of the control. This style is the default.
TCS_FOCUSONBUTTONDOWN 0x1000 The tab control receives the input focus when clicked.
TCS_OWNERDRAWFIXED 0x2000 The parent window is responsible for drawing tabs.
TCS_TOOLTIPS 0x4000 The tab control has a tooltip control associated with it.
TCS_FOCUSNEVER 0x8000 The tab control does not receive the input focus when clicked.

StatusBar Control Styles

These styles affect the StatusBar control. By default, it uses SBARS_TOOLTIPS and SBARS_SIZEGRIP (the latter only if the window is resizable). It has no forced styles.

Style Hex Description
SBARS_TOOLTIPS 0x800

Displays a tooltip when the mouse hovers over a part of the status bar that: 1) has too much text to be fully displayed; or 2) has an icon but no text.

The text of the tooltip can be set via:

SendMessage 0x0410, 0, "Text to display", "msctls_statusbar321", MyGui

The bold 0 above is the zero-based part number. To use a part other than the first, specify 1 for second, 2 for the third, etc. NOTE: The tooltip might never appear on certain OS versions.

SBARS_SIZEGRIP 0x100 Includes a sizing grip at the right end of the status bar. A sizing grip is similar to a sizing border; it is a rectangular area that the user can click and drag to resize the parent window.
