Overrides:

Parameters:

obj - the specified object.

updateVisibleActions

public void updateVisibleActions(UpdateMessage updateMessage)

Description copied from class: View

Called when the IDE or an extension requests that the View updates the enabled state of any actions that are visible on screen. Typically this will involve updating actions that are in visible toolbars. If a View contains or manages other nested instances of View, the outer call to updateVisibleActions should propagate inward to call the updateVisibleActions of all visible, nested Views.

Overrides:

updateVisibleActions in class View

Parameters:

updateMessage - information on what is triggering the update. Implementations may make use of this information to decide whether or not an update is necessary, since updating the enabled state of a toolbar button may be a lengthy operation. For example, buttons that control a remote debugger would involve network I/O and evaluating their updated state could be avoided if the updateMessage indicates that the source of the update is not relevant to the debugger.
