Méthodes publiques

Méthode	Description
Add ( ConsoleControl c ) : void	Adds the current control to the current focus context
ClearFocus ( ) : void	Clears the focus, but preserves the focus index
FocusManager ( ) : System	Initializes the focus manager
Pop ( ) : void	Pops the current focus context. This should be called if you've implemented a modal dialog like experience and your dialog has just closed. Pop() will automatically restore focus on the previous context.
Push ( ) : void	Pushes a new focus context onto the stack. This is useful, for example, when a dialog appears above all other controls and you want to limit focus to the dialog to acheive a modal affect. You must remember to call pop when your context ends.
Remove ( ConsoleControl c ) : void	Removes the control from all focus contexts
TryMoveFocus ( bool forward = true ) : bool	Tries to move the focus forward or backwards
TryRestoreFocus ( ) : bool	Tries to restore the focus on the given context
TrySetFocus ( ConsoleControl newFocusControl ) : bool	Tries to set focus on the given control.
