Is it possible to add item specific Conext-Menu Entries in a TreeField?
We need to add different Menu Entries in a TreeView depending on the type of Tree Element. We have different elements in the Tree or Elements with different states. Depending on the State we need a different Context Menu.

With Scout 4.0 we introduced a method:

execOwnerValueChanged(Object newOwnerValue)

which I think you can use.

The following code sets the context menu invisible if the selected node contains the text "Node 2". I hope this snippet helps.

          public class MenuAMenu extends AbstractExtensibleMenu {

            @Override
            protected String getConfiguredText() {
              return TEXTS.get("MenuA");
            }

            @Override
            protected void execOwnerValueChanged(Object newOwnerValue) throws ProcessingException {
              super.execOwnerValueChanged(newOwnerValue);
              if (getTree().getSelectedNode().getCell().getText().contains("Node 2")) {
                setVisible(false);
              }
              else {
                setVisible(true);
              }
            }
          }

Best regards,
Matthias
