coping with gradients and ScaledGraphics ? [message #243422]

Hi guys,

I'm having "fun" with Gef and doing some nice gradients with
setBackgroundPattern() - all looking nice and pretty...

Just until I start using the outline view which uses a ScaledGraphics to
give an "overview" map and getting exceptions
because ScaledGraphics does not support backgroundPattern.

I solved it currently by doing an instanceof check in paintfigure to avoid
the backgroundpattern in the outline view.

Is that really the only way around this ? Is there a "better"
scaledGraphics implementation somewhere ?

I'm also worried what happens when I start printing etc. ?

Hi Max,

I am not totally familiar with the history behind ScaledGraphics, but a
number of these SWT features do not scale so are not supported by
ScaledGraphics.

I have a question for you though.

You are able to show a gradient in your editor, do you have support to scale
your editor (zoom)? Are you using SWTGraphics?

Can you raise a Bugzilla for this? Not sure if there is one already.

Cheers...
Anthony

yes, but an approximation would be good ;)

We use a org.eclipse.draw2d.parts.Thumbnail (which in turn uses a
ScaledGraphics) to show a "birds-view" map of the graph
in the outline view which the user can use to quickly navigate somewhere
else.

Do you know any better way ?

Will do.

There were an existing bug for this (albeit with a bad title):
