Weird ComboBox behavior

wxPython Users
1

I've inserted a combo on my frame, and strangely when you open it, it only
displays one line, and that makes you scroll line per line until you find
your choice. Besides, it looks very ugly. :frowning:

This is the constructor I've used:
wxComboBox( self, -1, (""), wxDefaultPosition, wxSize(125,21),
comboBox1Strings, wxCB_READONLY )

I'm using Python 2.3, wxPython 2.4.2 and Win98
Anyone has an idea?

This is a known problem (which may have been fixed in 2.5, I don't recall right now) but the workaround is easy. The dropdown is affected by the size you pass in to the constructor, but if you give it a default value it should do the right thing. Try this:

  wxComboBox( self, -1, (""), wxDefaultPosition, wxSize(125,-1),
    comboBox1Strings, wxCB_READONLY )

If I remember correctly, it could have to do with the number of elements in
the list (comboBox1Strings) when the control is created. Do you have all
your strings in that list, or are you trying to add them later? I seem to
recall creating a list of 10 empty strings for initializing a ComboBox that
I needed to fill after it was created.

Hope that helps.

Unfortunatelly that didn't work. I had tried it before.
The workaround proposed by David did.
Thank you for helping
