class MyPanel(PythonPanel):
__alreadyOpen = False
def showModalDialog(self):
if MyPanel.__alreadyOpen:
return # or find command to bring it to the front
else:
MyWidget.__alreadyOpen=True
PythonPanel.showModalDialog(self)
This is usally what I use with Qt. But I tink there is no closeEvent or
hideEvent for a Pythonpanel to reset the __alreadyOpen?!
You also may want to check out other singleton patterns:

Hi all,
has anybody had success with enforcing only one instance of a PySide
widget when it's registered as a panel?
My app writes data to disk upon certain events and loads that data
again through the widget's constructor. So I need to make sure that
only one instance is open at any given time, otherwise I'm running the
risk of losing/corrupting that data.
Any ideas?
Cheers,
frank
