I am using DF in an application that uses heavyweight components (WorldWind). I have discovered that the lines used to indicate drag and drop in the Eclipse theme are hidden behind the heavyweight components. (See the attached screenshots where I replicated this behavior using java.awt.Label.)
Do you have any suggestions for resolving this?
Unfortunately there really is not much I can do, heavyweight Components just ignore lightweight components. To paint over them I would need to create some transparent window that covers the application - and then move around a lot of painting code. That involves just too much code to write. Sorry, heavyweight components are not supported, and will not be supported unless you implement it yourself (which of course would be wonderful).
Understood. Thanks for the input. Luckily, after some evaluation we determined that we can use GLJPanel instead of GLCanvas without any noticeable performance impact, and since GLJPanel is lightweight, it behaves as expected within DF.
