popupmenu

问题 I'm having a little scenario here that maybe a duplicate. I have JTable where i show some data, i have a mouselistener that listens for right clicks on the table and displays a popup menu with one menuitem.

However when I click on the popup menu, the StringGrid.Row is returned as -1.

问题 I've made a pop-up menu with one menu item, I want to enable it only when I do a right click on a tree item of a certain class type otherwise disable it.
