I'm currently programming a python program. The program has two threads. The main thread is running a GUI and the child thread is running some sort of installer. In some point, the child thread, needs to ask the user something (If he wants to install more stuff). In which way can the child thread send a message to the GUI-thread, that it needs to open a pop-up? (i cant use timeouts, only some sort of interuption)
Thank you very much!
