[Foxgui-users]FXSwitcher

[Davy D. <dd...@ne...>]

I noticed something about FXSwitcher that could possibly be improved...

   In my sound editor, I have some playing LED indicators which are just
labels with an FXIcon... Well, I put two labels on a switcher: one with
the 'LED-on' image and one with the 'LED-off' image...   So when playing
starts, I setCurrent(...) on the switcher and then again when it
stops...
   Well, in my situation, I have the waveform in another FX...Frame
above the status frame where the LEDs are.   When I switch the switcher,
it recalculates the layout of the switcher which causes everything in
the window to have to refresh, hence, the entire waveform view
redraws... I noticed this when I was printing everytime I draw part of
the waveform in order to figure out if I'm unnecessarily drawing many
times at startup (which I was, but I've supressed all the redraws during
initial layout adjustments until I know I'm ready)...

   Anyway, I understand that it may be necessary to re-layout stuff upon
using the switcher, but the two things in the switcher are the same
size, so it shouldn't be necessary to do the layout... I guess this
would just be a special case to check in the FXSwitcher implementation,
but it's one of those optimizations you can do after most everything
else is working.

(Anyway for now.. I'm going to put 2 labels on top if each other and use
raise() to bring to the top which ever I want to show... I only hope
this doesn't have the same side effect)
