This is a user interface toolkit mainly for audio plug-ins (VST, AudioUnit, etc). Based on the XML definition of the plug-in UI, VSTGUI includes an embedded editor (UIDescription Editor) which allows the developer to create a plug-in UI just by drag & drop of the UI element.
First developed in-house by Steinberg Media Technologies (around 1998) for their first VST plug-ins. Later added as binary libraries to the official VST SDK. Since May 2003, VSTGUI is open source, and is hosted now at GitHub https://github.com/steinbergmedia/vstgui.
The last official release version of VSTGUI is always included in the VST 3 SDK.
