TTM_WINDOWFROMPOINT
A version of this page is also available for
4/8/2010
This message allows an application to display ToolTip text for a window other than the one beneath the mouse cursor.
Syntax
TTM_WINDOWFROMPOINT wParam = 0;
lParam = (POINT FAR *) lppt;
Parameters
- wParam
Not used. Set to 0.
- lppt
Pointer to a POINT structure that defines a point in the window for which the ToolTip should display text.
Return Value
The return value is the handle to the window that contains the point. NULL indicates that no window exists at the specified point.
Remarks
This message is intended to be processed by an application that creates a subclass of a ToolTip. Applications should not send this message. A ToolTip sends this message to itself before displaying the text for a window. The point specified by lppt is obtained by calling the WindowFromPoint function. By changing the coordinates of the point specified by lppt, the application can cause the ToolTip to display text for a window other than the one beneath the mouse cursor.
