kTertiaryButton top-level constant Null safety

int const kTertiaryButton

The bit of PointerEvent.buttons that corresponds to a cross-device behavior of "tertiary operation".

It is equivalent to:

  • kMiddleMouseButton: The tertiary mouseButton.
  • kSecondaryStylusButton: The secondary button on a stylus. This is considered a tertiary button as the primary button of a stylus already corresponds to a "secondary operation" (where stylus contact is the primary operation).

See also:

  • kPrimaryButton, which describes a cross-device behavior of "primary operation".
  • kSecondaryButton, which describes a cross-device behavior of "secondary operation".

Implementation

const int kTertiaryButton = 0x04;
