setting widget as modal, disables button

[munna]

Hi,

I have written the following code in the constructor of class that reimplements QWidget

setAttribute(Qt::WA_DeleteOnClose);
setWindowModality(Qt::WindowModal);
setFixedSize(400,120);
setAutoFillBackground(true);
 
registerButton = new QPushButton(tr("Enter registraion key"),this);

setAttribute(Qt::WA_DeleteOnClose);
setWindowModality(Qt::WindowModal);
setFixedSize(400,120);
setAutoFillBackground(true);

registerButton = new QPushButton(tr("Enter registraion key"),this);

To copy to clipboard, switch view to plain text mode 

I am trying to get a modal widget (frameless) on top of my mainwindow. Parent of this widget is the mainwindow of the application. But the registerButton is disabled because of setWindowModal.

Anyideas on why the button is disabled and how can I prevent it from getting disabled ?

Thanks a lot

Are you using this code under Windows?

And if you rem the window modality line then everything works as expected? It could be some kind of bug... Why don't you use a dialog instead of a widget? If you already have a widget, you can always wrap it into a dialog:

QDialog dlg;
MyWidget *myWidget = new MyWidget;
QVBoxLayout *l = new QVBoxLayout;
l->addWidget(myWidget);
dlg.setLayout(l);
dlg.exec();

QDialog dlg;
MyWidget *myWidget = new MyWidget;
QVBoxLayout *l = new QVBoxLayout;
l->addWidget(myWidget);
dlg.setLayout(l);
dlg.exec();
