tps.input¶
Logic related to input devices.

exception
tps.input.
InputDeviceNotFoundException
¶ xinput
device could not be found.
-
tps.input.
generate_xinput_coordinate_transformation_matrix
(output, orientation)¶ Generates the coordinate transformation matrix that is needed for xinput to confine the input to one screen and rotate it properly.

tps.input.
get_wacom_device_ids
()¶ Gets the IDs of the built-in Wacom touch devices.
This calls
xinput
to get the list and parses that with a regular expression. Only device names starting withWacom ISD
(default regex) are taken into account. If you have an external device, this will not be picked up.Return type: list
-
tps.input.
get_xinput_id
(name)¶ Gets the
xinput
ID for given device.The first parts of the name may be omitted. To get “TPPS/2 IBM TrackPoint”, it is sufficient to use “TrackPoint”.
Raises: InputDeviceNotFoundException – Device not found in xinput
outputReturn type: int
-
tps.input.
get_xinput_state
(device)¶ Gets the device state.
Parameters: device (int) – xinput
ID of devicweReturns: Whether device is enabled Return type: bool
-
tps.input.
has_device_property
(device, property_)¶ Checks whether a given device supports a property.
-
tps.input.
has_xinput_prop
(device, prop)¶ Checks whether the device has the given xinput propery.
-
tps.input.
map_rotate_all_input_devices
(output, orientation)¶ Maps all Wacom® devices.
-
tps.input.
map_rotate_input_device
(device, matrix)¶ Rotates an input device.
-
tps.input.
map_rotate_wacom_device
(device, output, direction)¶
-
tps.input.
set_wacom_touch
(device_id, state)¶ Changes the Wacom Touch property of the given device.
-
tps.input.
set_xinput_state
(device, state)¶ Sets the device state.
Parameters: - device (int) –
xinput
ID of devicwe - state (bool) – Whether device should be enabled
- device (int) –
-
tps.input.
state_change_ui
(config_name)¶ Change the state of the given device depending on command line options.
It parses the command line options. If no state is given there, it will be the opposite of the current state.
Parameters: set_touch (bool) – Whether to also toggle the Touch
property on this device.Returns: None
-
tps.input.
wacom_rotate_reset
(device)¶ Resets the “Wacom Rotation” property of devices.
In GH-117 we noticed that in Ubuntu the
xrandr
rotation command will also rotate some input devices. This is probably meant in a good way but interferes with our rotation here. Therefore we reset the “Wacom Rotation” after setting the transformation matrix.
