Handling MessgeBox in CloseEvent
-
Hi,
why when i press no button the program will close?
@void MainWindow::closeEvent(QCloseEvent *event){
QMessageBox msg(this);
msg.setText("Are you sure you want to Quit?");
QAbstractButton *no=msg.addButton(tr("No"),QMessageBox::ActionRole);
QAbstractButton *yes=msg.addButton(tr("Yes"),QMessageBox::ActionRole);
if(msg.clickedButton()==no){
event->ignore();
}
else{
event->accept();
}
msg.exec();
}
@
thank u

Hi,
- addButton() returns void so no point in using it to compare.
- exec() will return the value of what you have clicked.
Have a look at the example "here":http://qt-project.org/doc/qt-5/qmessagebox.html#the-property-based-api.
Later you can use the return value of exec() to call ignore() on "No" to avoid closing of the program.
