问题 Is it possible that if a QDialog instance is exec() uted, the entire operating system is blocked until the user closes the dialog? In the following minimal example the dialog blocks only its parent widget but not the OS elements outside of the Qt application. rootwindow.h #ifndef ROOTWINDOW_H #define ROOTWINDOW_H #include <QApplication> #include <QMainWindow> #include <QtDebug> #include <QDialog> #include <QPushButton> #include <QMessageBox> #include <QBoxLayout> class RootWindow : public

问题 In my .NET Framework 4.5 Windows Forms project I have an async event handler. In the event handler I open a OpenFileDialog with ShowDialog() . Then I want to do something async with the selected file. But I have some weird behavior: After closing the dialog (with Cancel or OK button) I have got a delay of 9 seconds until the ShowDialog returned with its result. While this time the application is freezed. Here my code: private async void buttonBrowse_Click(object sender, EventArgs e) {
