在模态窗口中如何打开非模态窗口
|
你好， 根据你的描述，我进行了重现并正常显示了非模态对话框。 重现过程具体如下： 首先，新建一个基于对话框的MFC程序，默认情况下，主对话框就是以模态方式显示的(具体可见以下初始化代码)； 然后，为了测试，我插入了两个对话框。 插入一个对话框IDD_DIALOG1，并创建一个对话框类MyDialog1; 插入一个对话框IDD_DIALOG2，并创建一个对话框类ADDialog ; 最后，在主对话框中添加了两个按钮并添加相应的按钮响应事件； 具体代码片段请见以下： BOOL CMFCApplication1App::InitInstance() { ... CMFCApplication1Dlg dlg; m_pMainWnd = &dlg; INT_PTR nResponse = dlg.DoModal(); if (nResponse == IDOK) { // TODO: Place code here to handle when the dialog is // dismissed with OK } else if (nResponse == IDCANCEL) { // TODO: Place code here to handle when the dialog is // dismissed with Cancel } else if (nResponse == -1) { TRACE(traceAppMsg, 0, "Warning: dialog creation failed, so application is terminating unexpectedly.\n"); TRACE(traceAppMsg, 0, "Warning: if you are using MFC controls on the dialog, you cannot #define _AFX_NO_MFC_CONTROLS_IN_DIALOGS.\n"); } .. . } void CMFCApplication1Dlg::OnBnClickedButton2() { // TODO: Add your control notification handler code here MyDialog1 *dlgAD=new MyDialog1(); dlgAD->Create(IDD_DIALOG1,this); dlgAD->ShowWindow(SW_SHOW); ////////////////////////////////////// } void CMFCApplication1Dlg::OnBnClickedButton3() { // TODO: Add your control notification handler code here ADDialog *dlgAD=new ADDialog(); dlgAD->Create(IDD_DIALOG2,this); dlgAD->ShowWindow(SW_SHOW); }运行结果： 希望对你有帮助！ ;THE CONTENT IS PROVIDED ;AS IS; WITHOUT WARRANTY OF ANY KIND, WHETHER EXPRESS OR IMPLIED; Thanks We are trying to better understand customer views on social support experience, so your participation in this interview project would be greatly appreciated if you have time.
