We are about to switch to a new forum software. Until then we have removed the registration on this forum.
G4P 4.0.3 has just been released. Apart from some bug fixes there are visual enhancements for GButton controls (rounded corners) and scrollbars. New methods have been added to the GCScheme class to support the creation and editing of colour schemes.
My website has a new section where I am adding user guides for G4P. So far there is information on
1) Using multiple windows
2) Creating and editing colour schemes
3) Creating custom sliders
More will be added as I find the time to do them. If after looking at them you have suggestions for future guides please let me know.
