I had this problem in kshisen too. It's possible to work-around this 
without modifying Q/KMainWindow, but it's not that pretty. Of course, 
the ideal solution is to fix QMainWindow, but I can understand the 
desire for a more immediate solution.

KShisen (KDE_3_1_BRANCH) uses a workaround. Although you cannot manually 
change the size of the board, if the (fixed-size) board is too large 
for the users screen, then the board is scaled so that it does. (If you 
want to test this out without switching to 640x480 mode, replace the 
calls to kapp->desktop()->width() etc. in Board::setSize() in 
board.cpp.)

Did you miss the second half of this sentence? :-)

In kshisen (HEAD) we overcome that by drawing the tiles as big as 
possible (whilst still maintaining the aspect ratio) and padding the 
remaining area with the background pixmap.

I can understand that feeling. Personally so long as I can control the 
zoom level, I don't mind it if I accidently resize the window and when 
correcting it I end up with a size 2 pixels different to the original.
