Hello users,
I am writing a GUI with XRCed and it includes a ComboBox. I do not want to populate the ComboBox in XRCed but in my code. However, it seems that I can only do this during creation of the combobox. Is there a way to populate the combobox (or change the items in it) after it has been created. I do not find any method for this. Please help.

You can use SetItems() to populate it or change it. That works quite well for me.

Frans,
Mike's suggestion is the way to go. But how did he know of this method?
The trickis, when you think there should be a method but don't find it
listed under
the methods, try to *look at the methods of the class the widget is
derived from*.
So in the case of ComboBox, if you go the wxPython API page for that widget:
http://wxpython.org/docs/api/wx.ComboBox-class.html
You *don't* find .SetItems(). But that's when you should look and see on that
page a little family tree of the ComboBox widget, and see it is derived from a
class called ItemContainer. If you click on that, here:
http://wxpython.org/docs/api/wx.ItemContainer-class.html
You see it has methods which apply to ComboBox as well as a "sibling" class
called ControlWithItems (such as a Listbox of Choice widget). So, in
this ItemContainer
set of methods, you find sort of "more general" methods that apply to
anything with
a list of items; scrolling down the list you find SetItems(). Hooray.
(Of course, always
look for "Set" methods when you want to change something in the widget).
One caveat: If you do this same search job but look in the wxWidgets API
instead of the wxPython one, you actually don't find (or at least I
can't find) the
.SetItem() method. Can someone explain to me why this is? Where is it?
And so, it is useful to look in the wxPython API (though I find the wxWidgets
webpage easier to read somehow)
I just taught and so am in a pedagogical mood, but I hope this was
helpful to just
have somewhere, since it is a point that was very frustrating for me
until I began to
catch on that this is where to find "obvious" methods that weren't
found listed under
a widget's methods.

Another way to find the methods is to use Python's builtin introspection tool:s. I use dir and help in the python shell quite a bit. Here's what you'll get if you use them on ComboBox:
>>> import wx
>>> dir(wx.ComboBox)
# This will print a long list of methods and/or attributes
# cut for brevity
...
>>> help(wx.ComboBox.SetItems)
Help on method SetItems in module wx._core:
SetItems(self, items) unbound wx._controls.ComboBox method
Clear and set the strings in the control from a list
I apologize for not mentioning how I found that. It was recently added (I think) and I only learned about it by reading the archives. But Che is correct; you can find it in the way he described.

Hi Mike,
Yes, this works. Thanks.
The reason I didn’t find it is because it’s not in the manual which I am using (wxWidgets 2.8.8: A portable C++ and Python GUI toolkit).
Is there a newer version somewhere?

That's because SetItems and GetItems were implemented as part of the Items property in wxPython as a convenient way to populate the ComboBox.
If you look at the source wxPython/wx/_core.py, you can see that SetItems was implemented using the Clear and Append methods.

Thank you, Selim. Actually, now that you mention this,
I seem to recall a discussion about this maybe last
year, and, yes, prior to that one had to Clear the
items first, then use Append in a loop to add them again.
Thanks for clearing this up/refreshing my memory!

You're very welcome, and I'm glad it
was helpful!
Does anyone know whether all the various
points discussed here are found in one
place somewhere on the wiki? I think it
would be a great addition helping people
orient to what methods are available to them.
