The framework calls this member function when the user releases XBUTTON1 or XBUTTON2 of the mouse while the cursor is in the nonclient area of a window.
afx_msg void OnNcXButtonUp(
short nHitTest,
UINT nButton,
CPoint point
);
Parameters
Parameter |
Description |
|---|---|
[in] nHitTest |
The hit-test value returned by the CWnd::DefWindowProc function as a result of processing the WM_NCHITTEST message. |
[in] nButton |
A value of XBUTTON1 if the first mouse X button is released, or XBUTTON2 if the second X button is released. |
[in] point |
A CPoint object that specifies the x and y coordinates of the cursor relative to the upper-left corner of the screen. |
Remarks
This method receives the WM_NCXBUTTONUP notification, which is described in the Windows SDK. This message is posted to the window that contains the cursor. If a window has captured the mouse, this message is not posted.
Note
This member function is called by the framework to allow your application to handle a Windows message. The parameters passed to your function reflect the parameters received by the framework when the message was received. If you call the base-class implementation of this function, that implementation will use the parameters originally passed with the message and not the parameters you supply to the function.
