Method Detail

update

public void update(java.lang.Object source)

Description copied from class: UpdateAction

The update method is called when the UpdateAction is about to be displayed in UI. At this point, the UpdateAction may optionally update it's enabled state, shortText, longText, icon, etc so that it may be represented in appropriate state for the passed source.

Subclasses can override this method to dynamically change their state based on the current Node in the Browser, the current selected Node in the ProjectView, or whatever they like. Typically, the static method: public static Browser findBrowser(Object source) is called to acquire a Browser instance during the update process. If your action *always* requires a browser, use the BrowserAction subclass in the ide package.

NOTE: This method is called EVERY TIME a menu is about to display, or EVERY few milliseconds for toolbar buttons displaying this action. The code in the update method should be VERY SLIM and VERY FAST.

ANOTHER NOTE: This method is called EVERY few milliseconds if it is ever bound to a keystroke in the KeymapManager. When called from the KeymapManager, the passed source will *always* be the active Browser.

Overrides:

update in class UpdateAction
