Function Reference


_GUIToolTip_GetMaxTipWidth

Retrieves the maximum width of a ToolTip window

#include <GuiToolTip.au3>
_GUIToolTip_GetMaxTipWidth ( $hWnd )

Parameters

$hWnd Handle to the ToolTip control (returned by _GUIToolTip_Create.)

Return Value

Success: the maximum ToolTip width, in pixels.
Failure: -1.

Remarks

The maximum ToolTip width value does not indicate a ToolTip window's actual width.
Rather, if a ToolTip string exceeds the maximum width, the control breaks the text into multiple lines, using spaces to determine line breaks.
If the text cannot be segmented into multiple lines, it will be displayed on a single line.
The length of this line may exceed the maximum ToolTip width.
