How to create a modal window in pyqt?

Question

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.

Sorry for wasting your time. I realised that what i was looking for was a system modal dialog, i should have read the docs properly. I'll edit the question. I apologise, but do you know if it is possible to create a system modal dialog in ppyqt for linux. Thanks.

By System Modal you mean that your window should be on top of every other applications window? This is generally a bad idea and will end up frustrating your end user(s).

Its actually a license agreement for a linux distro.

FWIW: I of course meant to use exec_, I just happen to use the Qt reference usually. Since exec not only a python call but a keyword - the exec method can't exist in python anyway.
