Panel transitions

wxPython Users

I have a single frame and about 24 different panels that
make up the UI for some software I’m writing.

All the panels are hidden except one at a time, and the
panel that is visible takes up the entire frame.

Does that make sense?

I originally tried to instantiate each panel subclass only
as it was needed, but that was causing flickering too.

I remember reading (I think on this listserve)
that you should switch the panel by calling .Hide() on
one and .Show()

on the other. That being the case, I start the app w/
all panels instantiated and Hide all but my main menu, then Hide/Show as
needed.

I’m still seeing some flicker.

I’d like to be able to transition from one panel to
the other w/out flickering. Is
there some better way?

Can it be double buffered? I couldn’t find any examples for
this in the wiki or book.

Any help would be appreciated.

Hi Chris,

I have a single frame and about 24 different panels that make up the UI for
some software I'm writing.

All the panels are hidden except one at a time, and the panel that is
visible takes up the entire frame.

I'm still seeing some flicker.

Have you tried using:

yourFrame.Freeze()

# Here goes the code that show and hide things

yourFrame.Thaw()

? This should reduce the flickering.
