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;
[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.
A pointer to the CBasePane-derived object that contains the given point, or NULL if no pane was found.
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.
