boolean nsIControllerCommand::isCommandEnabled ( in string  aCommandName,
in nsISupports  aCommandContext 
) [inherited]

Returns true if the command is currently enabled.

An nsIControllerCommand can implement more than one commands; say, a group of related commands (e.g. delete left/delete right). Because of this, the command name is passed to each method.

Parameters:
aCommandNamethe name of the command for which we want the enabled state.
aCommandContexta cookie held by the nsIControllerCommandTable, allowing the command to get some context information. The contents of this cookie are implementation-defined.
