Del in edit treenode not working

wxPython Users

hello,

I've another small problem with CustomTreeCtrl:

I've bound the "Del" key (windows) to both a menu and an accelerator key:

    self.Bind ( wx.EVT_MENU, self.On_Delete, PU.items [5] ) # Del

    # Create bindings for accelerator keys
    aTable = wx.AcceleratorTable([\
        ( wx.ACCEL_NORMAL, wx.WXK_DELETE, PU.IDs[5] ),
        ])
    self.SetAcceleratorTable(aTable)

Because I normally want to use them to delete treenodes.
But in case I'm editing a treenode, I want that the "Del" has the normal editing functionality.
So I tried:

  def On_Delete ( self, event ) :
    if not ( self.GetEditControl () ) :
      self.Delete_Item ( self.GetSelection () )
    else :
      event.Skip ()

But the Skip() doesn't brings any help
So I tried the next, ...

  def On_Delete ( self, event ) :
    if not ( self.GetEditControl () ) :
      self.Delete_Item ( self.GetSelection () )
    else :
      event.m_keyCode = wx.WXK_DELETE
      self._textCtrl.EmulateKeyPress(event)

but the above gives the following error message:

Traceback (most recent call last):
  File "D:\Data_Python\P24_support\tree_support.py", line 177, in On_Delete
    self._textCtrl.EmulateKeyPress(event)
  File "P:\Python\Lib\site-packages\wx-2.8-msw-ansi\wx\_controls.py", line 1809, in EmulateKeyPress
    return _controls_.TextCtrl_EmulateKeyPress(*args, **kwargs)
TypeError: in method 'TextCtrl_EmulateKeyPress', expected argument 2 of type 'wxKeyEvent const &'

Any other ideas ?

thanks,

To use EmulateKeyPress you'll need to create a new wx.KeyEvent instead of using the wx.CommandEvent you are getting for the EVT_MENU.
