checkCommands

public void checkCommands(Context context,
                          Controller active)

Description copied from class: BaseController

checkCommands() should be called on the controller associated with the active view whenever the Context changes. The method gives the controller a chance to assign the enabled/disabled status of each of the context-sensitive Actions it owns. Calling this method on the active controller should cause all context-sensitive Actions owned by this controller and its supervisor's to be updated. No two controllers should attempt to update the status of the same action or else we would have redundant checking, which we want to avoid. checkCommands() should end by calling supervisor().checkCommands() to make sure actions dealt with by higher-level controllers get updated as well. This method is implemented by BaseController to call checkCommands() on the Ide itself. Note that the only context-sensitive Actions should be updated inside a checkCommands() method. Updating the enabled/disabled state of an action is handled by the update() command.

Specified by:

checkCommands in interface Controller

Overrides:

checkCommands in class BaseController

Parameters:

context - the current context. Null values are acceptable.

active - the controller associated with the active view. Null values are acceptable.
