Hi everyone! I’m trying to build an application in Python using wxpython library.
I would like to add and remove widgets dinamically like in the picture
so that i can add and remove how many StaticBoxSizer I want (each one containing Nome/Descrizione/Subject Area/etc).
I got a good result in adding widgets while I can’t get the way to remove the widgets. I’m successfull in destroying every widget in the StaticBoxSizer but I’m not able to destroy the container StaticBoxSizer itself: if I try to add many blocks and then removing one of them, in the onRemoveMaster method something happens and Python crash.
Thanks for helping!!
