Question about Eclipse GEF and RootEditPart - eclipse-gef

I am working on a eclipse based design editor. It's GEF based.
When I am adding root editpart to the editor , it's coming over top of my domain figures.
If I remove the rooteditpart , I am able to see my figures.
Any idea , what I may be missing ?
Thanks
Jijoy

I got it after some digging eclipse code. Need to set the bounds for figure only then it will show up.

Can anyone help me?
This is the code.
I apologize for my beginner knowledge.
If You want to do something like this the Thing You can do is Using a CSS file in javaFX FXML project
if its not a javaFX FXML Project then I'm afraid you must share the source code of your project...

Spring Elements not showing under Eclipse Navigator

Although i have enabled Spring Elements and i can see that when i right click on my project, it doesn't show up under my project in Navigator.
I installed the necessary plugins also but still cant figure out the issue.
How can i fix this?
Welcome to Spring tool 4. they have removed it. they are suggesting for go to symbol which can be achieved by Ctrl+6. But not that much helpful as Spring elements hierarchy.
How to use Ctrl+6 efficiently:

Reference to my statement:

The Navigator view directly shows the files and folders without virtual nodes. Use the Project Explorer view instead.

What type of View is that slim bar on the right side in Xcode?

Can anyone tell me how is it called, what is its purpose and how to hide it, please?
I believe that's part of the version control system.
Clicking the little "person's head in a circle" icon should close it.
Finally I got that. This is related to test coverage functionality and as you write unit/ui tests the right side with that red part appears. This has nothing to do with the vcs.

Is there a WYSIWYG option for IntelliJ IDEA when creating a GUI? (Like netbeans)

Been attempting to see if I can find a way to edit the gui form in the IntelliJ IDEA in a WYSIWYG format (pretty much the same as netbeans basically) is this possible?
If not, are you able to point me towards a reliable resource to learn how to learn to create an effective GUI layout (can either be book or online)
Yes there is a Form Designer in IntelliJ.
Please refer to this video
PS - go to Plugins first and ensure UI Designer is enabled.

Layout corrupted in ADF projects

I'm working on some projects on Jdeveloper 11.1.1.2.0 IDE and encounter an annoying problems. The layout of jspx pages corrupted, all control attached to any page disappear without a trace when running project. They dont show in design tab either. The problem appears suddenly when I modify some page.
Now I cant working on the project and have to restart project from scratch. So if you have encountered and fixed the same problem. Could you please show me how to do it. I'm very grateful to hear any suggestion.
Thank you.
Your description doesn't allow any educated guess on what happens. Can you at least paste the page source that you encounter the problem with ?
Often issues like this occur by developers placing the content to a facet that is not made for this and that does not stretch. Or if the a tag is not closed properly or missing (the page source editor should flag this)
Before starting from scratch, which should not bee needed at all, try JDeveloper 11.1.2.2 to reproduce it in a later build.
