CTooltip.WindowFromPointmethod

WindowsmethodCTooltip.incdocumented

Syntax

FUNCTION WindowFromPoint (BYVAL hTooltip AS HWND, BYVAL lppt AS POINT PTR) AS HWND

Also documented as UpdateTipText — one description covers them all.

Parameters

Name		Description
`hTooltip`		The handle of the Tooltip control.
`lpti`		Pointer to a TOOLINFOW structure. The hinst and lpszText members must specify the instance handle and the address of the text. The hwnd and uId members identify the tool to update. The cbSize member of this structure must be filled in before sending this message.
`hTooltip`		The handle of the Tooltip control.
`lppt`		Pointer to a POINT structure that defines the point to be checked.

Return value

The return value is the handle to the window that contains the point, or NULL if no window exists at the specified point.

Description

Sets the tooltip text for a tool.

Remarks

This message is intended to be processed by an application that subclasses a tooltip. It is not intended to be sent by an application. A tooltip sends this message to itself before displaying the text for a window. By changing the coordinates of the point specified by lppt, the subclass procedure can cause the tooltip to display text for a window other than the one beneath the mouse cursor.
