gc question

[vpalexander at gmail.com]

I keep seeing destructor calls in wx for ad hoc dialogs and wonder if
this is required, and if so, why would normal gc flow not be good?

  def GetDir(self,Caption,DefaultDir):
    dlg = wx.DirDialog(None,Caption,style = 1,defaultPath =
DefaultDir,pos = (10,10))
    res = dlg.ShowModal()
    pck = dialog.GetPath()
    dlg.Destroy()

    if res == wx.ID_OK:
      return pck
    else:
      return ''


I'd like to write it as:

  def GetDir(self,Caption,DefaultDir):
    dlg = wx.DirDialog(None,Caption,style = 1,defaultPath =
DefaultDir,pos = (10,10))

    if dlg.ShowModal() == wx.ID_OK:
      return dialog.GetPath()
    else:
      return '' # probably implied; del 2 more lines?

...and gc takes care of things once scope is exited? Or is wx more
tricksome than that?
