Common functions all TabletTool-Events implement.

Provided methods

fn time(&self) -> u32

The event time for this event

fn time_usec(&self) -> u64

The event time for this event in microseconds

fn distance_has_changed(&self) -> bool

Check if the distance axis was updated in this event.

For TabletToolProximityEvents this function always returns true. For TabletToolButtonEvents this function always returns false.

fn distance(&self) -> f64

Returns the current distance from the tablet's sensor, normalized to the range [0, 1].

If this axis does not exist on the current tool, this function returns 0.

fn dx(&self) -> f64

Return the delta between the last event and the current event.

If the tool employs pointer acceleration, the delta returned by this function is the accelerated delta.

This value is in screen coordinate space, the delta is to be interpreted like the return value of PointerMotionEvent::dx. See Relative motion for tablet tools for more details.

fn dy(&self) -> f64

Return the delta between the last event and the current event.

If the tool employs pointer acceleration, the delta returned by this function is the accelerated delta.

This value is in screen coordinate space, the delta is to be interpreted like the return value of PointerMotionEvent::dy. See Relative motion for tablet tools for more details.

fn pressure_has_changed(&self) -> bool

Check if the pressure axis was updated in this event. For TabletToolButtonEvents this function always returns false.

fn pressure(&self) -> f64

Returns the current pressure being applied on the tool in use, normalized to the range [0, 1].

If this axis does not exist on the current tool, this function returns 0.

fn rotation_has_changed(&self) -> bool

Check if the z-rotation axis was updated in this event.

For TabletToolButtonEvents this function always returns false.

fn rotation(&self) -> f64

Returns the current z rotation of the tool in degrees, clockwise from the tool's logical neutral position.

For tools of type TabletToolType::Mouse and TabletToolType::Lens the logical neutral position is pointing to the current logical north of the tablet. For tools of type TabletToolType::Brush, the logical neutral position is with the buttons pointing up.

If this axis does not exist on the current tool, this function returns 0.

fn slider_has_changed(&self) -> bool

Check if the slider axis was updated in this event.

For TabletToolButtonEvents this function always returns false.

fn slider_position(&self) -> f64

Returns the current position of the slider on the tool, normalized to the range [-1, 1].

The logical zero is the neutral position of the slider, or the logical center of the axis. This axis is available on e.g. the Wacom Airbrush.

If this axis does not exist on the current tool, this function returns 0.

fn tilt_x_has_changed(&self) -> bool

Check if the tilt x axis was updated in this event.

For TabletToolButtonEvents this function always returns false.

fn tilt_y_has_changed(&self) -> bool

Check if the tilt y axis was updated in this event.

For TabletToolButtonEvents this function always returns false.

fn tilt_x(&self) -> f64

Returns the current tilt along the X axis of the tablet's current logical orientation, in degrees off the tablet's z axis.

That is, if the tool is perfectly orthogonal to the tablet, the tilt angle is 0. When the top tilts towards the logical top/left of the tablet, the x/y tilt angles are negative, if the top tilts towards the logical bottom/right of the tablet, the x/y tilt angles are positive.

If this axis does not exist on the current tool, this function returns 0.

fn tilt_y(&self) -> f64

Returns the current tilt along the Y axis of the tablet's current logical orientation, in degrees off the tablet's z axis.

That is, if the tool is perfectly orthogonal to the tablet, the tilt angle is 0. When the top tilts towards the logical top/left of the tablet, the x/y tilt angles are negative, if the top tilts towards the logical bottom/right of the tablet, the x/y tilt angles are positive.

If this axis does not exist on the current tool, this function returns 0.

fn size_major_has_changed(&self) -> bool

Check if the size major axis was updated in this event.

For TabletToolButtonEvents this function always returns false

fn size_minor_has_changed(&self) -> bool

Check if the size minor axis was updated in this event.

For TabletToolButtonEvents this function always returns false

fn size_major(&self) -> f64

Returns the current size in mm along the major axis of the touching ellipse. This axis is not necessarily aligned with either x or y, the rotation must be taken into account.

Where no rotation is available on a tool, or where rotation is zero, the major axis aligns with the y axis and the minor axis with the x axis.

If the axis does not exist on the current tool, this function returns 0.

fn size_minor(&self) -> f64

Returns the current size in mm along the minor axis of the touching ellipse. This axis is not necessarily aligned with either x or y, the rotation must be taken into account.

Where no rotation is available on a tool, or where rotation is zero, the minor axis aligns with the y axis and the major axis with the x axis.

If the axis does not exist on the current tool, this function returns 0.

fn wheel_has_changed(&self) -> bool

Check if the wheel axis was updated in this event.

For TabletToolButtonEvents this function always returns false.

fn wheel_delta(&self) -> f64

Return the delta for the wheel in degrees.

fn wheel_delta_discrete(&self) -> f64

Return the delta for the wheel in discrete steps (e.g. wheel clicks).

fn x_has_changed(&self) -> bool

Check if the x axis was updated in this event.

For TabletToolButtonEvents this function always returns false.

fn y_has_changed(&self) -> bool

Check if the y axis was updated in this event.

For TabletToolButtonEvents this function always returns false.

fn x(&self) -> f64

Returns the X coordinate of the tablet tool, in mm from the top left corner of the tablet in its current logical orientation.

Use x_transformed for transforming the axis value into a different coordinate space.

Note

On some devices, returned value may be negative or larger than the width of the device. See Out-of-bounds motion events for more details.

fn y(&self) -> f64

Returns the Y coordinate of the tablet tool, in mm from the top left corner of the tablet in its current logical orientation.

Use y_transformed for transforming the axis value into a different coordinate space.

Note

On some devices, returned value may be negative or larger than the width of the device. See Out-of-bounds motion events for more details.

fn x_transformed(&self, width: u32) -> f64

Return the current absolute x coordinate of the tablet tool event, transformed to screen coordinates.

Note

This function may be called for a specific axis even if x_has_changed returns false for that axis. libinput always includes all device axes in the event.

On some devices, returned value may be negative or larger than the width of the device. See Out-of-bounds motion events for more details.

fn y_transformed(&self, height: u32) -> f64

Return the current absolute y coordinate of the tablet tool event, transformed to screen coordinates.

Note

This function may be called for a specific axis even if y_has_changed returns false for that axis. libinput always includes all device axes in the event.

On some devices, returned value may be negative or larger than the width of the device. See Out-of-bounds motion events for more details.

fn tool(&self) -> TabletTool

Returns the tool that was in use during this event.

Note

Physical tool tracking requires hardware support. If unavailable, libinput creates one tool per type per tablet. See Tracking unique tools for more details.
