If you want to set the focus to a window, you MUST call SetFocus() on that window. A side effect of this call is that the window which is losing the focus gets a WM_KILLFOCUS message and the window which receives the focus gets a WM_SETFOCUS message, both of which are informing t...

举个例子,重载了关闭的小叉叉 void CAboutDlg::OnClose() { // TODO: 在此添加消息处理程序代码和/或调用默认值 DoSomthing(0; // 执行自己的判断等等 // CDialog::OnClose(); // 把向导生成的父类调用给注释了,这时就关不了对话框了。 } 补充回答,点叉叉会发送WM_CLOSE消息,如果需要重载的话,应该在...
使用自定义用户消息的方法,如下: #defineWM_USER_SETFOCUS_MSG(WM_USER+1) BEGIN_MESSAGE_MAP(CMainDlg, CDialogEx) ... ON_MESSAGE(WM_USER_SETFOCUS_MSG, OnUserSetFocus) END_MESSAGE_MAP() LRESULT CMainDlg::OnUserSetFocus(WPARAM wParam, LPARAM lParam) { ::SetFocus(m_wndEdit); return S_OK...

1、区别:OnDraw是一个纯虚函数,定义为virtual void OnDraw( CDC* pDC ) = 0; 而OnPaint是一个消息响应函数,它响应了WM_PANIT消息,也是是窗口重绘消息。 2、联系:我们一般在视类中作图的时候,往往不直接响应WM_PANIT消息,而是重载OnDraw纯虚函数,这是因为在CVIEW类中的WM_PANIT消息响应函数中调用了OnDraw...
第一,OnOK()和OnCancel()是CDialog基类的成员函数,而OnClose()和OnDestroy()是CWnd基类的成员函数,即WM消息响应函数。从应用程序结构的角度,拿对话框来说,红色的X对应的是CWnd,而处于对话框中的“确定”、“取消”按钮则对应了CDialog。 第二,OnClose()和OnDestroy() ...

若要向文本服务对象发出控件正在获取或失去焦点的信号,主机会发送 WM_SETFOCUS 并WM_KILLFOCUS 消息。 另请注意,无窗口主机将作为 wParam (窗口传递 NULL,该窗口丢失了这些消息的焦点) 。 从非活动状态直接转换到 UI 活动状态时,主机应先调用 ITextServices::OnTxInPlaceActivate ,然后调用 ITextServices::On...
