Very convenient!

Thanx for sharing.

You are welcome!

For the other thread: I think about clothes. Without MD ;)

That very useful, thank you.

one question, how can I add an option that allows me to select all?

This shows "SingleChoiceDialog" and "MultiChoiceDialog" as it is provided by wxPython as a quick solution. If you need it more complicated, you need to create your own dialog.

But I'm sure I also showed a dialog with "select/deselect all" somewhere :).
