hello -
could anyone point me in the correct direction on how (is this even possible)
i could change the text color in a view? if a project is part of cvs, and the
contents change, i would like to be able to change the color of the file name
to help make it stand out better.
also, when trying to create a GC object w/ a baseImage, such as any label
icon that is associated w/ a java file, xml file, etc i receive an "Invalid
Arugment" exception.
after digging thru the code, it appears that i can only create new GC objects
on bitmaps and not "icons" - why is this so? and what labels an image as an
icon vs a bitmap (i think it has something to do w/ transparency, but not
sure). if i wanted to change the color of one of those labels (say the
"package" label icon that is accociated w/ a java package [it's orange and has
a "plus" sign thru it]) can i build a GC object somehow and manipulate the the
image color that way, or am i going to have to redraw the entire image
"dynamically" (pixel by pixel).
thanks!!!

ok - so once i implement that interface, i can control the colors for the
given element, but then how do i "hook up" the implementation so that the view
knows to use it?
thx!

Set it as your viewer's label provider.

i could just subclass the label provider and set it w/ that instead, however
i'm not really sure that's the best approach (just b/c if that class ever
changes, my code breaks).

No. A viewer has exactly one label provider. You can subclass an
existing label provider and set it to your viewer. Maybe instead of
changing the colour you could use a decorate (see ILabelDecorator).

grrr - ok - i had initially explored the use of the label decorator, but ran
into problems trying to change the color of the image decoration b/c i can't
create a GC object against it. (according to the eclipse code, that "icon" is
transparent, and therefore i can't create a new GC object w/ it).
that pretty much left me having to re-draw the image pixel by pixel to get
the effects i want, which i guess is ok, but i haven't quite figured out how to
accomplish that task yet.
is there any way i could manipulate the text color of a label decoration
instead? i'm guessing no since the decorateText method returns a String.
