Hi there!

I created a GButton of the G4P library and added this button successfully to my panel - it has now the color of the current colorscheme. Is there a way to change to color of the button AFTER adding it to the panel?

I don’t know how to address this specific button after adding the control to the panel.

Regards,  
Eric

There are [2 users guides](http://www.lagers.org.uk/g4p/guides/g01-overview.html) on my website covering colour schemes and changing colours of individual controls I suggest you have a look.

If you need to access a control after its been created then keep its identifier global
