First that I am testing these components. It looks that the units of the drawers needed have to be added to the uses clause. In the Lazarus LCL folder I see only CustomDrawn_Common, CustomDrawn_Mac, CustomDrawn_WinXP, CustomDrawn_Android, no Win2000, no Win7, no KDEPastique, no GNOME. And the existing ones are far from being complete, they usually implement only drawing of the buttons. What am I missing? Is there a demo project somewhere?
