How to create a modal window in pyqt?


I looked into the documentation and I found self.setWindowModality(QtCore.Qt.WindowModal).

I added this function to my __init__ function, but however still was not able to create a modal dialog box.

Any help will be appreciated,
Thank You.


Solution

  • QDialog has setModal() as found here.

    As the docs state:

    By default, this property is False and show() pops up the dialog as modeless. Setting this property to true is equivalent to setting QWidget.windowModality to Qt.ApplicationModal.

    As @sebastian noted you could use exec(). However it is better to use exec_() as the one sebastian mentioned is also a python call.

    Example:

    my_dialog = QDialog(self) 
    my_dialog.exec_()  # blocks all other windows until this window is closed.
    

    If this doesn't help please post your code and I will have a look.
