I have made a new QGIS Plugin, almost everything is working fine, but I can click on my Plugin-Button several times and it starts several times. So I see my Plugin 4 or 5 times. How can I prevent that?

Almost no Plugin out there shows this behavior, but I can't figure out what I do have to change.

If you have a QDialog (you didn't exactly specify what your Plugin opens) you could set it modal.

In Qt Designer by ticking the modal checkbox:

Qt Designer modal

Or in the corresponding *.py:

self.setModal(True)
  • Thank you very much, yes, I open a QDialog. I friend of mine helped me to develop a solution for the problem, but I knew that there has to be a very simple way, I just did not know, that the solution is so amazingly simple!!! – AndreasK Dec 6 '15 at 12:24
