MirInputDeviceCapabilities

typedef unsigned int MirInputDeviceCapabilities

MirInputDeviceId

typedef int64_t MirInputDeviceId

MirPointerAcceleration

typedef enum MirPointerAcceleration MirPointerAcceleration

MirPointerAcceleration describes the way pointer movement is filtered:

• mir_pointer_acceleration_none: (acceleration bias + 1.0) is applied as a factor to the current velocity of the pointer. So a bias of 0 to results to no change of velocity.
• mir_pointer_acceleration_adaptive: acceleration bias selects an acceleration function based on the current velocity that usually consists of two linear inclines separated by a plateau.

MirPointerHandedness

typedef enum MirPointerHandedness MirPointerHandedness

MirTouchpadClickMode

typedef enum MirTouchpadClickMode MirTouchpadClickMode

MirTouchpadClickMode configures how the touchpad itself should generate pointer button events.

The available click modes may be active simultaneously.

• mir_touchpad_click_mode_none: no active click mode
• mir_touchpad_click_mode_area_to_click: simulate pointer buttons using click areas on the touchpad
• mir_touchpad_click_mode_finger_count: simulate pointer buttons using the number of fingers down

MirTouchpadClickModes

typedef unsigned int MirTouchpadClickModes

MirTouchpadScrollMode

typedef enum MirTouchpadScrollMode MirTouchpadScrollMode

MirTouchpadScrollMode configures how the touchpad should generate scroll events.

• mir_touchpad_scroll_mode_none: no scroll
• mir_touchpad_scroll_mode_two_finger_scroll: two finger movement generates generates vertical and horizontal scroll events
• mir_touchpad_scroll_mode_edge_scroll: touch movement at the edge of the touchpad genertes scroll events
• mir_touchpad_scroll_mode_button_down_scroll: movement on the touchpad generates scroll events when a button is held down simultaneously

MirTouchpadScrollModes

typedef unsigned int MirTouchpadScrollModes

MirTouchscreenMappingMode

typedef enum MirTouchscreenMappingMode MirTouchscreenMappingMode

Mapping modes for touchscreen devices.

The mode defines how coordinates from the touchscreen frequently referred to as device coordinates are translated into scene coordinates.

This configuration mode is relevant for different classes of input devices, i.e handheld devices with builtin touchscreens or external graphic tablets or external monitors with touchscreen capabilities.
