Detailed Description

The NavigationManipulator supports these navigation directions and default keyboard keys for them:

  • Up: Up Arrow key
  • Down: Down Arrow key
  • Left: Left Arrow key
  • Right: Right Arrow key
  • Home: Home key
  • End: End key
  • Page up: Page Up key
  • Page down: Page Down key

The manipulator recognizes only one navigation key gesture at a time. When Kanzi recognizes a key-pressed gesture for a navigation key, the manipulator grabs the key input and blocks any key input until Kanzi recognizes the key-released gesture for the pressed navigation key.

When the user presses, holds down, releases, or cancels a navigation key, Kanzi dispatches a dedicated message for each navigation key. Kanzi dispatches a key-pressed message when the manipulator detects the key- pressed, key-hold, or key-repeat gesture. When focus moves, Kanzi cancels a key-pressed and key-hold gesture. You can cancel a key-pressed gesture for a navigation key with the cancel() method.
