CWnd::OnMButtonDblClk

afx_msg void OnMButtonDblClk( UINT nFlags, CPoint point );

Parameters

nFlags

Indicates whether various virtual keys are down. This parameter can be any combination of the following values:

MK_CONTROL Set if the CTRL key is down.
MK_LBUTTON Set if the left mouse button is down.
MK_MBUTTON Set if the middle mouse button is down.
MK_RBUTTON Set if the right mouse button is down.
MK_SHIFT Set if the SHIFT key is down.

point

Specifies the x- and y-coordinate of the cursor. These coordinates are always relative to the upper-left corner of the window.

Remarks

The framework calls this member function when the user double-clicks the middle mouse button.

Only windows that have the CS_DBLCLKS WNDCLASS style will receive OnMButtonDblClk calls. This is the default for all Microsoft Foundation Class windows. Windows generates an OnMButtonDblClk call when the user presses, releases, and then presses the middle mouse button again within the system’s double-click time limit. Double-clicking the middle mouse button actually generates four events: WM_MBUTTONDOWN and WM_MBUTTONUP messages, the WM_MBUTTONDBLCLK call, and another WM_MBUTTONUP message.

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.
