Pixmap memory consumption

[bunjee]

Hey there, I'm developping a Qt app.

At some point in my application I'm loading 500 widgets and 1000 pixmap inside of it.

Since some pictures appears 2+ times, I've created a Pixmap "pool" manager to load once and for all a given Pixmap.


Here are the figures, compiled in static release :

at the beginning : my app takes 10 000 K of memory.
when 1000 Pixmap + Widgets loaded : my app takes 32 000 K of memory.
when unloaded : my app STILL takes 32 000 K of memory (if my Vista control panel is right).


I'm pretty sure I've deleted everything.

I'm not sure what could eat up so much memory since my "Pixmap manager" claims to contain 10 pixmap at the end.
