[maemo-developers] Maemo UI Development for N800/N810

[From: kumar lomash]

Hi,

I have been developing GUI using GTK +2.0 and now I am facing some
performance issues. Let me first describe

The implementation: -
The UI consists of layouts (GtkContainers) which have event box and image
widgets. At any given time only one of the four layouts is visible and the
user can select a layout at any given time. On an average each layout has 25
buttons (internally event boxes and image widgets). Every button has 3
states so there are 6 (3 event + 3 image) widgets for every button. A total
of 4 layouts make 600 widgets roughly at any given time.

The Problem: -
Whenever user switches between layouts, I hide other layouts (hide the
containers) and show the selected layout. The problem is that it takes very
long to do these operations.

Is there a better way of doing this? I used event boxes and image widgets in
place of gtkbuttons because I needed custom shaped buttons with custom
bitmaps over them.

Please help!

Regards,
Lomash
