quick visual question

[Nathan smith]

Hi there,

I'm running wx python classic, and have the following code:

 def setup_screen1(self):

  # code to create a panel and sizer goes here...

  self.info1 = wx.ListCtrl(panel, -1, style = wx.LC_REPORT)
  hbox1.Add(self.info1, 1, wx.EXPAND|wx.ALIGN_LEFT|wx.ALL,5)

  # code for adding items to the list, and the rest of the panel code
goes here.


That works as expected.

My question is this.

In my program, I would like the info list to show up on multiple screens.

I do not call panel.Destroy() at any time, though I hide and show it a
few times.

therefore, is this code okay?

 def setup_screen2(self):

  #create the panel and sizer
  hbox1.Add(self.info1, 1, wx.EXPAND|wx.ALIGN_LEFT|wx.ALL,5)

  # code for the rest of the panel.


will this add the same list, that looks the same on every screen correctly?

thanks

Nathan

No, a widget can only have one parent at a time. You could use the Reparent method to switch it over to a new parent panel when needed, but usually it's better to just create a new listctrl for each panel.  If you're concerned about duplicating the data in each listctrl then you could use the wx.LC_VIRTUAL flag and keep your data in a list or some other data object that they all share. The listctrl will then ask you, via overridden methods, for the data and attributes as it needs them for display.
