CMDIChildWndEx::PaneFromPoint
Returns the pane that contains the given point.
CBasePane* PaneFromPoint(
CPoint point,
int nSensitivity,
bool bExactBar,
CRuntimeClass* pRTCBarType
) const;
CBasePane* PaneFromPoint(
CPoint point,
int nSensitivity,
DWORD& dwAlignment,
CRuntimeClass* pRTCBarType
) const;
Parameters
[in] point
Specifies the point, in screen coordinates, to check.[in] nSensitivity
Increase the search area by this amount. A pane satisfies the search criteria if the given point falls in the increased area.[in] bExactBar
TRUE to ignore the nSensitivity parameter; otherwise, FALSE.[in] pRTCBarType
If not NULL, the method searches only panes of the specified type.[in] dwAlignment
If a pane is found at the specified point, this parameter contains the side of the pane that was closest to the specified point. For more information, see the Remarks section.
Return Value
A pointer to the CBasePane-derived object that contains the given point, or NULL if no pane was found.
Remarks
Call this method to determine whether a pane contains the specified point according to the specified conditions such as runtime class and visibility.
When the function returns and a pane was found, dwAlignment contains the alignment of the specified point. For example, if the point was closest to the top of the pane, dwAlignment is set to CBRS_ALIGN_TOP.
