Paul DiLascia 写了一个类来锁定 CToolBar,我用它来创建这个类,它将在 CMFCToolbar 上工作。你可以复制它来为 CMFCMenuBar 做同样的事情——只需将 MFCToolBar 更改为 MFCMenuBar 就可以了。
class CLockedMFCToolBar : public CMFCToolBar
{
public:
CLockedMFCToolBar() : CMFCToolBar() {}
protected:
LRESULT CLockedMFCToolBar::WindowProc(UINT msg, WPARAM wp, LPARAM lp)
{
if ((msg==WM_LBUTTONDOWN || msg==WM_LBUTTONDBLCLK))
{
// Got click or double-click and toolbar is locked: if mouse in "dead
// zone" then ignore the message--don't pass to control bar
CPoint pt(lp);
if (OnToolHitTest(pt, NULL) == -1)
return 0; // return without handling: bypass control bar dragging!
}
// pass unhandled messages subclassed window--this is important!*/
return CMFCToolBar::WindowProc(msg, wp, lp);
}
};
