I haven't yet been able to install the control's icon successfully.
I have installed an icon in the .hidden/control folder of the project but the icon shown in collection of controls is a default one with no icon.
Any advice would be welcome

 Hi Bill, exactly what are you trying to do, I don't quite understand the question?

I've created a custom control, it was showing in the IDE in a default form, not appearing with the icon that I'd set.
Have re-read /dev/gambas - Gambas Documentation for the umpteenth time I realised that the icon name has to be in lower case - problem solved!
