Supprimer l'élément de listBox wxpython

Question

J'ai cette classe qui traite avec listBox: J'ai essayé de faire un bouton de suppression pour les éléments de la liste de contrôle, mais cela n'a pas fonctionné. La fonction "deleteItem" fonctionne maintenant.Sans les parties marquées cela fonctionne bien, mais il n'y a pas d'option de suppression. Aider quelqu'un?

Voici la version, avec la permission du commentaire de Robin Dunn:
Notez que j'ai aussi lié la textctrl afin que remplissant simplement un nom de processus et en appuyant sur Entrée, agit également comme le bouton Add.

Il est un peu plus compliqué que d'avoir de double de Id pour vos boutons, comme je l'ai suggéré plus tôt.
les opérations suivantes: (Je suis coincé avec votre global ProcessListMain, mais a dû se moquer vers le haut, comme il n'est pas déclaré dans votre code Questions)

import wx 
class SettingProcess(wx.Frame): 
    itemsArr= []

     panel = wx.Panel(self, wx.ID_ANY,size=(500, 600)) 
     self.index = 0

     lbl_process = wx.StaticText(panel, -1, "Process name") 
     lbl_process.SetFont(wx.Font(10, wx.SWISS, wx.NORMAL, wx.BOLD)) 
     self.txt_processname = wx.TextCtrl(panel, size=(140, -1))
