[Solved]Make a widget "untouchable"

[TheDestroyer]

When a QMessageBox::warning() is called, the underlying widget becomes "untouchable", per se. I can't call it disabled, and I don't know what it officially is called. In the old days of Visual Basic 6.0, I used to call the command enabled = 0, to have that effect done on a widget. This didn't work in Qt.

I have an options dialog, which if shown, I'd like to have the mainwindow untouchable till the dialog is hidden again, just like when a QMessageBox::warning() is displayed. How can I do that???

Thanks for any efforts :)

Well I think that you are talking about Modal Dialogs. You can set the property of the dialog before displaying For eg:

@void MainWindow::on_btnOpen_clicked()
{
Dialog *d = new Dialog(this);
d->setModal(true);
d->show();
}@

You can read: "Modal Dialog ":http://qt-project.org/doc/qt-4.8/QDialog.html#modal-dialogs

Hi,

There is a modal and windowModality property.
check also the enum Qt:WindowModality for detailed description of modal-modes :)

To achieve this, on usually calls "exec() ":/doc/qt-4.8/qdialog.html#exec on a [[doc:QDialog]] subclass. exec() blocks, so the calling method isn't ended until the dialog is closed.

Thanks a lot!!!! the QDialog::setModal() did the trick. :)
