Interesting Refresh

wxPython Users

Hi,

I designed an interface by using wxFormBuilder. Everything works
correctly. But there is an interesting situation.
The first time I touch the combobox on the interface, my listbox on
the same interface refreshes. When I touch it the other times, it
doesnt occur any more. I am curious why that happens.

Thanks.

Platform? Version? Runnable sample code?

Does your listbox start out with the keyboard focus? If so, you could
just be seeing an artifact of losing focus.

I'm seeing it too on Windws7, but not on XP. As suggested before it does indeed have something to do with the listbox losing the focus, as clicking on it again (to give it the focus) and then again on the combo does cause the refresh flicker again. My guess is that there is something new in the native widget implementation that is causing this, I don't know if there is anything we can do to avoid it or to work around it.

You should create a ticket at trac.wxwidgets.org about this, perhaps one of our Windows gurus will know what is going on.
