Well if it is a function already in Win32Lib, why does IDE need to do
anything but make it available?
One possible problem, which may be what you are up against is that
percentages don't necessarily add up. For example 25% of 15 pixels would
be 4 to the nearest one, but 4 lots of 4 makes 16 and is a pixel to big.
So buttons may have cracks between or slightly overlap.
If this is your problem then I can offer you a solution. First convert
from x, y, cx, cy to x, y, (x+cx), (y+cy) and then proportion these by the
% and then convert back to x, y, cx, cy. Example:
x=.30, y=.10, cx=.06, cy=.03 ==> x=.30, y=.10, (x+cx)=.36, (y+cy)=.13 and
then for a 800x600 window this gives 240, 60, 288, 78 which are all
integers so it would have worked anyway.
But for a 1024x768 window 307.2, 76.8, 368.64, 99.84 which are then
converted to nearest integer giving 307, 77, 369, 100 and so you get
x=307, y=77, cx=62, cy=23.
What this method does is ensure that two object edges which fitted exactly
before still fit perfectly after scaling (whereas scaling x, y, cx, cy
will not achieve this). Previously identical sized objects may vary in
size by 1 pixel which should not be a problem. It can be avoided by very
careful selection of grid sizes to start with.
