Questions tagged [firemonkey]

FireMonkey(tm) is the cross-platform GUI framework developed by Embarcadero Technologies, a part of Idera Inc. and is a part of the RAD Studio development tool.

FireMonkey is a cross-platform UI framework for Windows, Mac OS X, iOS and Android providing windows and controls on both 2D surfaces and 3D environments. It uses GPU-accelerated rendering, allowing smooth effects and animation to be applied to controls and other on-screen images, and is vector-based and skinnable, building its controls from a library of underlying primitives. Skins give close-to-native look and feel.

FireMonkey currently supports Mac OS X, Win 32bit & 64bit as well as iOS and Android.
