WM_CONTEXTMENU<虚截获>,响应右键

1.示例功能

实现超链接效果

概要向导解析:

1.自定义文本控件<就是从CStatic进行类派生>

2.从工具栏直接拖原始控件就行.<但是在主界面Dialog中别忘了替换绑定也就是利用DDX_Control将资源控件ID和该派生出来的对象进行绑定>

3.重写相关虚函数.<这里有个概念认知,父类中的非虚拟函数是设计成不被子类改写的。根据有无virtual关键字,PreSubclassWindow重写>

好了,下面直接贴代码了:

从CEdit中派生出CMyEdit类,添加WM_CONTEXTMENU消息,并添加消息响应函数.

void CMyEdit::OnContextMenu(CWnd* pWnd, CPoint point) 
{
if (point.x == -1 && point.y == -1)
{
CRect rect;
GetClientRect(rect);
ClientToScreen(rect);

point = rect.TopLeft();
point.Offset(5, 5);
}
CMenu menu;
VERIFY(menu.LoadMenu(m_menuID));
CMenu* pPopup = menu.GetSubMenu(0);
ASSERT(pPopup != NULL);
CWnd* pWndPopupOwner = this;
while (pWndPopupOwner->GetStyle() & WS_CHILD)
pWndPopupOwner = pWndPopupOwner->GetParent();
pPopup->TrackPopupMenu(TPM_LEFTALIGN | TPM_RIGHTBUTTON, point.x, point.y,
pWndPopupOwner);
}
