All,
I am creating a palette less
eclipse plugin where am adding figures to the custom editor through the contextual menu, but am not finding a way to do it. Can anyone please guide me as to how to go about adding figures to editor dynamically through context menu i.e. adding actions/commands.
Since
Eclipse GEF plugin development finds so less examples to look at, I am adding my solution so others find it useful. This code helps to render a node to the editor.
Source code for Action class to render figures to the editor:
public class AddNodeAction extends EditorPartAction
{
public static final String ADD_NODE = "ADDNODE";
public AddNodeAction(IEditorPart editor) {
super(editor);
setText("Add a Node");
setId(ADD_NODE); // Important to set ID
}
public void run()
{
<ParentModelClass> parent= (<ParentModelClass>)getEditorPart().getAdapter(<ParentModelClass>.class);
if (parent== null)
return;
CommandStack command = (CommandStack)getEditorPart().getAdapter(CommandStack.class);
if (command != null)
{
CompoundCommand totalCmd = new CompoundCommand();
<ChildModelToRenderFigureCommand>cmd = new <ChildModelToRenderFigureCommand>(parent);
cmd.setParent(parent);
<ChildModelClass> newNode = new <ChildModelClass>();
cmd.setNode(newNode);
cmd.setLocation(getLocation()); // Any location you wish to set to
totalCmd.add(cmd);
command.execute(totalCmd);
}
}
@Override
protected boolean calculateEnabled()
{
return true;
}
}
