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.

Can we see some code? – user3419537 Jul 11 '14 at 13:30

2Using a QDialog in combination with its `exec` method, should be sufficient and avoids the need to set the modality explicitly: http://qt-project.org/doc/qt-4.8/qdialog.html#exec – sebastian Jul 11 '14 at 13:47

QDialog has setModal() as found here.
As the docs state:
By default, this property is
Falseandshow()pops up the dialog as modeless. Setting this property to true is equivalent to settingQWidget.windowModalitytoQt.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.

1Sorry 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. – user3135832 Jul 12 '14 at 10:03

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). – Shadow9043 Jul 12 '14 at 11:18

1FWIW: 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. – sebastian Jul 14 '14 at 07:14

how to show a dialog blocks only some windows rather than the entire application? – bactone Sep 02 '21 at 09:26
