Property Value



True if the primary action mode; otherwise false.


Examples of primary action modes for various input devices:

  • A touch pointer when it is in contact with the digitizer surface.
  • A pen pointer when the pen tip is in contact with the digitizer surface and no modifying buttons, such as a barrel button (see IsBarrelButtonPressed), are pressed. An eraser tip does not set this property either (see IsEraser).
  • A mouse pointer when the left mouse button is pressed.
