Sometimes you are chaning .mif files, but Symbian still shows the old content.
The reason is simple: there's AknIconSrv.exe which caches them.
If you clear icon cache you:
- get more RAM
- can replace widgets, avkon2, app icons and other .mif files on the fly
You CAN'T:
clearing icon cache doesn't cause automatically redrawing EVERYTHING, this means you have to remove and re-add .e.g. a widget or shortcut on homescreen to see the new one.
killing ailauch.exe (homescreen process) does solve this, but also creates a lot of bugs.
Clearing icon cache itself is a simple thing, you can find it e.g. in Nokia R&D filebrowser.
1. in your project file add:
LIBS +=-laknicon #libary which contains the needed class AknIconConfig
TARGET.CAPABILITY += WriteDeviceData #Symbian Plattform Security, we all love you
2. in your implementation include:
#include <akniconconfig.h> //header of AknIconConfig class
3. the code:
AknIconConfig::EnableAknIconSrvCache(EFalse);
AknIconConfig::EnableAknIconSrvCache(ETrue);
it simply disables the icon cache (what does clear it) and re-enables it.
In theory you can disable it always, but than your phone will reload .mif files all the times what's bed for the performance (a lot of IO operations).
