Methods

RegisterCommand(ICommand, KeyGesture, object?, bool)

Registers a command to invoke when the specified key combination is pressed.

void RegisterCommand(ICommand command, KeyGesture gesture, object? argument = null, bool handlesGesture = false)

Parameters

command ICommand

Command instance to register.

gesture KeyGesture

Keys combination to trigger the command.

argument object

Argument to pass to the command when the gesture is pressed.

handlesGesture bool

true to let this command take the gesture over: commands registered this way are tried before the others, the most recently registered first, and the first whose CanExecute(object) returns true runs alone. When none of them can execute, every other command for the gesture runs as usual. false (the default) runs the command together with the gesture's other ordinary commands.

UnregisterCommand(KeyGesture)

Unregisters every command bound to the specified key combination.

void UnregisterCommand(KeyGesture gesture)

Parameters

gesture KeyGesture

Keyboard combination to remove the commands for.

UnregisterCommand(ICommand, KeyGesture)

Unregisters one command from the specified key combination, leaving the gesture's other commands in place.

void UnregisterCommand(ICommand command, KeyGesture gesture)

Parameters

command ICommand

The command to remove.

gesture KeyGesture

The key combination it was registered for.
