Cannot understand how to get data from checklistbox in wxpython

Answer 1

checkedItems = [i for i in range(citList.GetCount()) if citList.IsChecked(i)]

citList.GetChecked() should have also completed the task for you. May the problem be that you are trying to get selected items in __init__?

Upd.: You do not want to get checked items during __init__ - they cannot be checked by the user at that moment. You'd better check them in any event handler, e.g. wx.EVT_BUTTON.

Try writing self more often, e.g.:

self.citList = wx.CheckListBox(self, -1, (60, 50), wx.DefaultSize, allLoc)
# some code
self.panel = citPanel(self, -1)

and change Clicked to:

def Clicked(self, event):
    checkedItems = [i for i in range(self.panel.citList.GetCount()) if self.panel.citList.IsChecked(i)]
    print checkedItems
    event.Skip()

Hope this helps.
