Hey people :-)
Well I've run into a slight problem and I'm a bit baffled as to what
is wrong so I am looking to yeerselves for some insight.
I have as follows.....
One editor
A getter that returns the StyledText of said editor.
Code to set the line background ...
IWorkbench wb = org.eclipse.ui.PlatformUI.getWorkbench();
Device dev = wb.getDisplay();
Color orange = new Color(dev, 255, 127, 0);
editor.getTextWidget().setLineBackground(10, 5, orange);
I'm at a loss as to why it's not working, any advise
welcome.
Thanks for you time,
A.

I'm new to SWT, but two questions that may help you
1) Is the Workbench device, the same as the StyledText device?
2) When are you disposing of orange? I'm not sure but I would imagine that
the lifetime of orange would have to be as long as the styledText has that
background line.... So for example if you were doing this:
Color orange = new Color(dev, 255, 127, 0);
editor.getTextWidget().setLineBackground(10, 5, orange);
orange.dispose();
Then I think the background won't show as expected. The solution I can offer
to that is to not dispose of orange so earlier, but do it later... However
don't forget to dipose it ;)
Like I said I'm new to SWT, so this might not shed any light on the
problem... (but if you do find the solution, then I'll be happy to hear it)

Yup I changed that, not long after I posted, to use the
editor.getTextWidget().getDisplay().

I'm currently not disposing of the orange. I will of course
be changing this in the future.
Thanks,
