Performance: Sizer vs. Panel

wxPython Users

Ok, I made a small sample of my month-view...

I've cleaned the code from needless and awkward things, so the performance is a little better.

But I'm still not sure whether the way I make a month-view is far too complicated.

I would be happy for comments from you.

Thanks a lot.

I wasn't suggesting that you use Grid itself, that would probably not be
a very good choice. I was suggesting that like the Grid you self-draw
the calendar content on a single (or maybe a few) widget(s) instead of
using hundreds of independent widgets.

No, but in order to help you get better performance of your current
solution we'll probably need you to duplicate it in a small-as-possible
runnable sample that we can experiment with.

After seeing it I can only reiterate that drawing the calendar yourself in a single window would be better than using hundreds of windows. It's the difference between 1 medium complex paint event handler plus one size event handler vs. hundreds of simple paint events plus hundreds of size events plus dozens of layouts.

Thank you for your help!

This makes sense to me. Furthermore the InspectionTool helps me better understand, what happens behind the scenes...

I thought, I do not have to paint every day by myself, cause a panel make all that stuff for me. But I want to understand much more about the things that not to see on screen... :slight_smile:
