[protege-discussion] Disable "delete class" item from menu

[robber82 at email.it]

Thanks, I would also disable or delete the "delete class" item in
"popup menu", not only in headers button. Can you help me?

ClsesTab. Instead, I  suggest that you build your own Tab widget and that
you reuse all the  components from the classes tab. In this way you can
customize the UI  and the behavior of the tab in any way you like.  You can
start by subclassing edu.stanford.smi.protege.widget.ClsesTab,  e.g.
let's say you call your class MyClsesTab. Then, you need to  override
the method createClsesPanel() which creates the panel that  holds the
classes tree and all the create and delete buttons. This  method should
return a ClsesPanel.  To remove or disable to delete button, subclass
ClsesPanel, say  MyClsesPanel. The constructor of MyClsesPanel, should look
like:  public MyClsesPanel(Project project) {      super(project);      
//this will remove the button with index 3 (the delete button)      
_labeledComponent.removeHeaderButton(3); }  Going back to the MyClsesTab,
the createClsesPanel() method should look  like:      protected ClsesPanel
createClsesPanel() {         MyClsesPanel panel = new
MyClsesPanel(getProject());         panel.addSelectionListener(new
SelectionListener() {             public void
selectionChanged(SelectionEvent event) {                
transmitSelection();             }         });         return panel;     } 
That's it. So, all you need to do is to override 2 methods the way that 
I have described. You can also add more customization to your tab. To 
enable your tab, go to Project ->Configure and select
"MyClsesTab".  We have more documentation on building plugins
