CWnd::OnLButtonDblClk

Syntax

afx_msg void OnLButtonDblClk( UINT nFlags, CPoint point );

Parameters

nFlags

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

Value Description

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

Called when the user double-clicks the left mouse button.

Only windows that have the CS_DBLCLKS WNDCLASS style will receive OnLButtonDblClk calls. This is the default for Microsoft Foundation Class windows. Windows calls OnLButtonDblClk when the user presses, releases, and then presses the left mouse button again within the system's double-click time limit. Double-clicking the left mouse button actually generates four events: WM_LBUTTONDOWN, WM_LBUTTONUP messages, the WM_LBUTTONDBLCLK call, and another WM_LBUTTONUP message when the button is released.

This message-handler member function calls the Default member function. Override this member function in your derived class to handle the WM_LBUTTONDBLCLK message.
