All LCL widgetsets (interfaces) are supposed to be 100% compatible. Lets take the simplest case. A new application with a single button on the main form. That will work no matter which LCL widgetset you use. Simply toggle the LCLWidgetType setting between LCL-Qt, LCL-GTK2, LCL-fpGUI and recompile, and the application will run without any code changes. They will all be LCL based applications, just they will use a different underlying (wrapped) GUI toolkit. But as I mentioned, they are supposed to be 100% compatible, but in reality they are not. Some widgetsets support features others don't. eg: LCL-Qt supports MDI applications, but the others don't. LCL-GTK2 allows tabsheets with tabs on the right edge but text is still horizontal, other LCL widgets don't. LCL-Cocoa doesn't allow a Form.Color property change, but other widgetsets do. The list goes on. This is the major drawback of LCL - inconsistency across platforms and widgetset interfaces. Pure fpGUI applications (that don't rely on LCL) don't have this problem. When working on a LCL application, also take a look in the Object Inspector window. There is a "Restricted" tab which lists features of each widget that works on some LCL interfaces but not on others. That list is not 100% complete either.
