Hi,

Thanks for all the help I am getting from this forum.

I know some basics of core Java and not anything beyond that. One of my friends suggested me to go through Eclipse 4 tutorial once as I wanted to develop an app as explained below.

I want to build an application in which I want to define some UI components (Say a component looking as a geometric figures "circle" and "triangles") which I should be able to see in say Left Pane. And I want to drag them to the Right Pane.
I should also be able to right click on these components and add options to it. Say an option to change color to RED.

I want to develop a graph with these UI components as nodes and want to connect them with simple lines. I have started with the tutorials on Eclipse 4 and thinking that I should be able to develop a simple app with this. But I am not sure what all things I can use and how to develop it.

Can anybody help here and tell me how should I proceed and what all tutorials I can go through.

If anybody have already worked on similar thing please share your thoughts on it.

Thanks,
Peeyush

First, learn more than the core basics of Java. This forum is intended for specific questions regarding Eclipse4.

Once you know more than the basics, look at GEF or Graphiti.

For sure I am doing that. And as I mentioned I have started with the tutorials on Eclipse4 and thinking that I should be able to develop the app with this.

So wanted to know, what all help is available with Eclipse 4, so that it will be little easier to develop such app and will look more professional in structure.

As I saw, creating Menus and writing Handlers are much easier here. What all such help can be taken from it for the intended app ?

So I feel it is related to Eclipse4 and expecting some help on it.

Eclipse 4 is now widget-toolkit neutral: you first need to decide which toolkit to use, whether that be SWT, JavaFX, or even Vaadin. If you choose SWT, take a look at Veronika Irvine's article:
