CWnd::OnMouseMove

  • 项目

afx_msgvoidOnMouseMove(UINTnFlags**,CPointpoint);**

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 mouse cursor moves. If the mouse is not captured, the WM_MOUSEMOVE message is received by the CWnd object beneath the mouse cursor; otherwise, the message goes to the window that has captured the mouse.

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.
