Hello!
I make a new Tab in Editor in TBC by following:
I use extention "org.topbraidcomposer.editors.pages". My factory class
"AdvGraphFactory":
public class AdvGraphFactory extends GraphEditorPageFactory {
@Override
public IResourceEditorPage createPage(ResourceEditor editor, String
id, String title) {
IResourceEditorPage page;
page = new AdvGraphEditorPage(editor, id, title);
return page;
}
}
The page-class "AdvGraphEditorPage":
public class AdvGraphEditorPage extends FormPage implements
IResourceEditorPage {
public GraphicalViewer graphicalViewer;
public AdvGraphEditorPage(ResourceEditor editor, String id, String
title) {
super(editor, id, title);
// TODO Auto-generated constructor stub
}
public void createPartControl(Composite parent) {
super.createPartControl(parent);
graphicalViewer = createGraphicalViewer(parent); //
configures viewer
}
...
}
I've tried to add/configure menus/graphical elements etc - no effect.
When I take away "super.createPartControl(parent);" from the method
"public void createPartControl(Composite parent)" I become a following
error:
