How to Create a combobox in the InstallationNode

URCap Development Java
1

Hi,
I have just started working on the development of URCap and I am finding difficult to create a JComboBox in the GUI of Installation node. I’ve tried to use the drop-down list example of lightup urcap and I found out that UndoRedoManager works exclusively on Program node.
Since I want to create a JComboBox for features, how do I create an installercontribution object to insert into the drop-down list?

I’m using as reference urcap the sample of com.ur.ursim.examples.createfeatureswing and the Starter Package v1.13.

The instance of the installation contribution will get passed from the Service, which is instantiated from the Activator class on a bundle.registerService() call. You should see examples of this happening in your reference programs. As for the undoRedo manager, you’re correct, you don’t need to use that in the installation node. However, everything else is the same. You should be able to construct a combobox the same way as you would on a program node.
