[Panel-devel] [PATCH] QPixmapCache size (bug 151109)

[Sean Harmer]

HI All,

Please find a proposed patch that attempts to automatically set the size of 
the QPixmapCache for plasma to a size that is (hopefully) suitable on an 
arbitrarily sized set of screens. I and many other people have been bitten by 
this bug when testing out KDE 4 svn builds and this is something that gives a 
bad impression form the word go. So I thought I'd try a quick fix. ;-)

I am taking the conservative approach and assuming a bit depth of 32bpp. I 
tried to use QPixmap::defaultDepth() but this was only returning 24bpp, i.e. 
it did not include an alpha channel on my setup here.

I have (arbitrarily) increased the calculated value by 10% to allow some 
leeway. If anybody with more information knows of a more realistic heuristic 
than this then please feel free to change it. :-)

Kind regards,

Sean
