This is a rather a beginner question. I'm heavily modifying some code that was an LDAP address book to be a sqlite3 based address book. I have the basic GUI working and I'm now getting the database connections to work.
This question relates to how one communicates between windows/GUIs. When the program starts theres a main GUI, class name abookgui. If you want to add new entries or modify existing entries an edit GUI is started in a separate window, class abookeditgui. I need the abookeditgui window to be able to tell the parent abookgui window that it has completed whatever it was doing. It has two basic possibilities 'Cancel', i.e. nothing was changed or 'Save' meaning there's a new/changed item in the database. The parent abookgui needs to know when one of these has happened. What's the 'right' way to do this? I can see several non-event driven ways of doing it badly but I'm not sure of the proper event driven way. The parent abookgui only has the name of the abookeditgui object, it can of course access the abookeditgui instance variables so it can hook (for example) a window exit event (I think!). There are (of course) event handlers for the 'Save' and 'Cancel' button click events in abookeditgui, what I need is hooks from these to run some code in abookgui after the abookeditgui has completed. How should one do this, is there a way for a class to call code in the class 'above' which instantiated it? -- Chris Green ยท -- https://mail.python.org/mailman/listinfo/python-list
