deselect an iterm in ListBox wxPython

[Bailu]

Hi,

I am a newbie in wxPython and doing a program with ListBox,
I want to select and deselect items in this box,
I have use

self.devlist = wx.ListBox(self , style=wx.LB_MUL TIPLE)
self.Bind(wx.EV T_LISTBOX, self.select_dev , self.devlist)

to create this box, but don't know how to implement self.select_dev
to find out which one is clicked

deselect it, if it was selected ( this is not working at default)
select it, if it was not (toggle)

The default behavior is, the selection is increasing, I can't deselect
any of them.

Thanks.

You should look at the wxPython demo's code for the wx.ListBox. It
looks like they use the wx.EVT_LISTBOX event. See below:

<code>
# this writes to a multiline TextCtrl
self.log.WriteT ext('EvtListBox : %s, %s, %s, %s\n' %
(event.GetStrin g(),
event.IsSelecti on(),
event.GetSelect ion(),
event.GetClient Data()))
</code>

I'm not sure, but I think it uses the SetSelection() method to select
an item, which seems to deselect the previously selected item...at
least, that's how I interpret the demo.

The demo is here: http://wxpython.org/download.php
