Question

How to dim / fade all other windows of an application in Delphi 2009.

Form has an AlphaBlend property, but it controls only transparency level. But it would be nice if

Answer 1

I'm not sure about the "right" way to do it, but in order to "fade-to-white", what you can do is place your form in another completely white form (white background color, no controls).

So when your form is in 0% transparency, it will show as a regular form, but when it's in 50% transparency it will be faded to white. You can obviously choose other colors as your background.

I'm looking forward to seeing other answers...

EDIT: after seeing your "Jedi Concentrate" link, it seems that a dark-gray background will mimic the Expose effect better.
