input. The provided signals just relay the basic information of the
stylus events.

getAxis
Arguments
| :: (HasCallStack, MonadIO m, IsGestureStylus a) | |
| => a |
|
| -> AxisUse |
|
| -> m (Bool, Double) | Returns: |
getBacklog

| => a |
|
| -> m (Bool, [TimeCoord]) | Returns: |
By default, GTK will limit rate of input events. On stylus input where accuracy of strokes is paramount, this function returns the accumulated coordinate/timing state before the emission of the current motion signal.
This function may only be called within a motion
signal handler, the state given in this signal and obtainable through
gestureStylusGetAxis call express the latest (most up-to-date)
state in motion history.
The backlog is provided in chronological order.
getDeviceTool
gestureStylusGetDeviceTool Source #
Arguments
| :: (HasCallStack, MonadIO m, IsGestureStylus a) | |
| => a |
|
| -> m (Maybe DeviceTool) | Returns: The current stylus tool |
Returns the DeviceTool currently driving input through this gesture.
This function must be called from either the down,
motion, up or proximity
signal handlers.
new
Arguments
| :: (HasCallStack, MonadIO m) | |
| => m GestureStylus | Returns: a newly created stylus gesture |
Creates a new GestureStylus.
