Color setting for GLabel components of GUI4Components

in Contributed Library Questions • 2 years ago

Is there a simple way to set the color for GLabel items (border color, text color, background color). There are constants in the GConstants for these items but it appears no callbacks to set those components.

Any possible solutions or suggestions?

I tried to find the document referenced item for instructions on set_user_color (spelling?), but only found the definitions and no instructions (the original reference re-directed to the Google code repository).

Thanks

Yes there is a simple way.

Every G4P component has an attribute called localColor which specifies the colours to be used. So for a GLabel called label we can change the colours it uses with

label.localColor.lblFont = color(255,0,0); // red text
label.localColor.lblBack = color(255,255,200); // pale yellow background
label.localColor.lblBorder = color((0,0,128); // dark blue border

localColor is of type GScheme so look in that class for the variable names for the other components.

Thank you for your reply. I had attempted to get to this point but was missing what you provided. Very much appreciated. This finally gets me out of having to use app.rect() with fill colors to get the result I needed.
