Question: I'd like to make a tool bar with icons that get's bigger when you mouse over them. I don't mind reinventing the wheel, but if anyone can suggest a good:

1. Image Format (not sure bitmaps'll work here and not sure how to do Vectors)
2. Existing Control (pay or free, so long as I can use it in a close source app)
3. Container class (is TPanel sufficient?)

Answer: 
I've not used it yet personally, but maybe check out TMS TAdvSmoothDock rather than reinventing wheel..?

There is some sample code doing exactly this on the delphi.about.com website.

The link below shows the code as well as an example image of the dock while running.

I don't know if the code is D2009 compatible or not, but even if it isn't the code shouldn't be that hard to bring forward. I would think anyways.

HTH,

Ryan.
