问题 Javadoc for JPopupMenu constructor says the following: JPopupMenu public JPopupMenu(String label) Constructs a JPopupMenu with the specified title. Parameters: label - the string that a UI **may** use to display as a title for the popup menu. Key word being "may". Evidently in the default UI, such titles are ignored when creating a popup menu.

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.

Because my drop down list is going to be serving as a dynamic history at RunTime, means it going to be empty at compile time. This means I can't add an event handler through the standard route of using the designer surface (On
