The problem is, I don't really have enough "room" or space in my

resized when my slider is dragged?? Or is there a way that I can
draw a rectangle or something "in front" or "over" all of my
window's controls, and hide that rectangle once the slider is
released??
I'm not really looking for exact code, but more for ideas on how to
implement something like that...
Keep it simple: why not just use two text fields, for width and
height. The user can then drag the slider or simply type in the sizes
they want. For bonus points, add a checkbox to preserve aspect
ratio... While not as 'exciting' as a rectangle preview, it's probably
more useful. Additional feedback such as the amount the image is going
to be scaled by might be an idea too (e.g. '1.5x', '2.3x', etc)
Incidentally, in most interfaces where I have a value that is changed,
I use the triple whammy - slider, text field and stepper, all setting
the same thing. Then the user can't really complain that they don't
have options ;-)
