Function Reference

GUICtrlCreateLabel

Creates a static Label control for the GUI.

GUICtrlCreateLabel ( "text", left, top [, width [, height [, style = -1 [, exStyle = -1]]]] )

Parameters

text The text of the control.
left The left side of the control. If -1 is used then left will be computed according to GUICoordMode.
top The top of the control. If -1 is used then top will be computed according to GUICoordMode.
width [optional] The width of the control (default text autofit in width).
height [optional] The height of the control (default text autofit in height).
style [optional] Defines the style of the control. See GUI Control Styles Appendix.
    default ( -1) : none.
    forced styles : $SS_NOTIFY, $SS_LEFT
exStyle [optional] Defines the extended style of the control. See Extended Style Table.

Return Value

Success: the identifier (controlID) of the new control.
Failure: 0.

Remarks

To set or change information in the control see GUICtrlUpdate...() functions.

To combine styles with the default style use BitOR($GUI_SS_DEFAULT_LABEL, newstyle, ... ).
To use the values specified above you must #include <StaticConstants.au3> in your script.

Default resizing is $GUI_DOCKAUTO size and position will occur.

The extended style $GUI_WS_EX_PARENTDRAG can be used to allow the dragging of the parent window for windows that don't have a titlebar (no $WS_CAPTION style in GUICreate()).

To set the background to transparent, use GUICtrlSetBkColor(-1, $GUI_BKCOLOR_TRANSPARENT).

If you really need to create a label that overlap other control you can set the style to $WS_CLIPSIBLINGS.
In fact that has a little performance drawback as mention see $WS_CLIPSIBLINGS forum.
