Submission from: (NULL) (129.128.206.243)
The following code works under twm, mwm, window maker, and sawfish but
not under fvwm2. Under Red hat 7.3 compile it by placing it in
a file main.cpp under a directory called main. Then compile with:
qmake -project; qmake; make
and run with ./main
There are two problems:
1) Upon startup the grid is not 10x10 as it is under twm.
2) When the window is grabbed with the mouse, made really thin, then
really tall and wide, and this is done many times quickly before
the mouse is released, the window exhibits some strange resizing
behavior and ends up resizing itself to some unreasonable size.

setBaseSize(W, bar->height() + H);
resize(width(), height() - contentHeight % H);
}

for (i = 0; i < height() / H; i++)

p.drawRect(j * W, i * H + bar->height(), W, H);
