[SOLVED] [listbox] Feed it with dict passed to class?

[Winfried]

Hello,

This is a newbie question.

Is it possible to feed a listbox with a dictionary (to get text + hidden value) passed through the class as input parameter?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45

import wx   class MoveItemListBox(wx.ListBox):   def __init__(self, *args, **kwds):       """       #With sampleList_dict:       TypeError: ListBox(): arguments did not match any overloaded call:         overload 1: too many arguments         overload 2: argument 'choices' has unexpected type 'dict'       """       super().__init__(*args, **kwds)         #"choices" is part of **kwds       #BAD for k, v in items.items():       #BAD for k, v in items():       #BAD for k,v in choices.items():       #BAD for k,v in choices:         self.Append(k, v);         self.Bind(wx.EVT_LISTBOX, self.EvtListBox)           def EvtListBox(self, event):     name = event.GetString()     data = str(event.GetClientData())     #self.statusbar.SetStatusText(f"{name}: {data}")         class TestFrame(wx.Frame):   def __init__(self):       wx.Frame.__init__(self, None, title="Move item in ListBox")       self.SetSize((370, 400))       panel = wx.Panel(self)         sampleList_dict = {'key1': 'value1', 'key2': 'value2', 'item3': 'value3'}       self.list_box = MoveItemListBox(panel, choices=sampleList_dict, size=(100, 200), style=wx.LB_SINGLE)         sizer = wx.BoxSizer(wx.HORIZONTAL)       sizer.Add(self.list_box, 0, wx.EXPAND|wx.RIGHT, 4)       panel.SetSizer(sizer)       self.Layout()   if __name__ == '__main__':   app = wx.App()   frame = TestFrame()   frame.Show()   app.MainLoop()

Thank you.

Edit: A work-around is to create a list with just the keys, and use it to fetch the values from the dictionary:

1 2 3 4 5 6 7 8 9 10 11

#ListBox doesn't accept dictionaries, only list data = {'key1': 'value1', 'key2': 'value2', 'key3': 'value3'} data_keys = list(data)   class TestFrame(wx.Frame):   def __init__(self):       wx.Frame.__init__(self, None, title="Move item in ListBox")       self.SetSize((370, 400))       panel = wx.Panel(self)         self.list_box = MoveItemListBox(panel, choices=data_keys, size=(100, 200), style=wx.LB_SINGLE)

you can get key and value like:

1 2	for key, value in sampleList_dict.items():     print(key, value)

Thanks. The problem is that a listbox only accepts lists, not dictionaries. So I guess I'll have to keep two objects to work with a listbox. No biggie.

wxpython list box can accept strings one at a time, doesn't have any requirement for a list.
