[maemo-developers] Application icons

[From: Christian Kandeler]

Hi,

when writing Qt applications for Maemo, 
http://wiki.maemo.org/Packaging_a_Qt_application advises to add the 
following to one's .pro file:
   iconxpm.path = $$DATADIR/pixmap
   iconxpm.files += ../data/maemo/$${TARGET}.xpm

   icon26.path = $$DATADIR/icons/hicolor/26x26/apps
   icon26.files += ../data/26x26/$${TARGET}.png

   icon48.path = $$DATADIR/icons/hicolor/48x48/apps
   icon48.files += ../data/48x48/$${TARGET}.png

   icon64.path = $$DATADIR/icons/hicolor/64x64/apps
   icon64.files += ../data/64x64/$${TARGET}.png

Unfortunately, it does not mention what these icons are for. Apparently, 
the 64x64 size is for the task launcher, but I was not able to find 
anything about the other ones. Sow which version of the icon is used in 
which context? And what about the pixmap?


Thanks,
Christian
