Delphi’s FireMonkey is a great framework for cross platform app development, but it lacks many components both visual and non-visuals.
The comprehensive component library were what made Delphi so great in the old days.
Anyways, I just have to write it myself for my applications. This is what I wrote recently. A Web2.0 look & feel button, with curved lighting on top half. Button’s colour is a property you change to any colour you want, and it will generate the button graphics on the fly.
