The ratbagd DBus-Interface -------------------------- Note: **the DBus interface is subject to change** Interfaces: - org.freedesktop.ratbag1.Manager - org.freedesktop.ratbag1.Device - org.freedesktop.ratbag1.Profile - org.freedesktop.ratbag1.Resolution - org.freedesktop.ratbag1.Button - org.freedesktop.ratbag1.Led For a list of dbus types as used below, see https://dbus.freedesktop.org/doc/dbus-specification.html Properties marked as 'constant' do not change for the lifetime of the object. Properties marked as 'mutable' may change, and a `org.freedesktop.DBus.Properties.PropertyChanged` signal is sent for those unless otherwise specified. org.freedesktop.ratbag1.Manager =============================== The **org.freedesktop.ratbag1.Manager** interface is the entry point to interact with ratbagd. ### Properties: #### `Devices` - type `ao`, read-only, mutable Provides the object paths of all current devices, see **org.freedesktop.ratbag1.Device** #### `Themes` - type `as`, read-only, constant Provides the list of available theme names. This list is guaranteed to have one theme available ('default'). Other themes are implementation defined. A theme listed here is only a guarantee that the theme is known to libratbag and that SVGs *may* exist, it is not a guarantee that the SVG for any specific device exists. In other words, a device may not have an SVG for a specific theme. This list is static for the lifetime of ratbagd. org.freedesktop.ratbag1.Device ============================== The **org.freedesktop.ratbag1.Device** interface describes a single device known to ratbagd. ### Properties: #### `Id` - type: `s`, read-only, constant An ID describing this device. This ID should not be used for presentation to the user. #### `Description` - type: `s`, read-only, constant The device's name, suitable for presentation to the user. #### `Capabilities` - type: `au`, read-only, constant The capabilities supported by this device. see `enum ratbag_device_capability` in libratbag.h for the list of permissible capabilities. #### `Svg` - type: `s`, read-only, constant The device's SVG file name, without path. #### `Profiles` - type: `ao`, read-only, mutable This property is mutable if the device supports adding and removing profiles. Provides the list of profile paths for all profiles on this device, see **org.freedesktop.ratbag1.Profile**. ### Methods: #### `Commit() → ()` Commits the changes to the device. Changes to the device are batched; they are not written to the hardware until `Commit()` is invoked. #### `GetSvg(s) → (s)` Returns the full path to the SVG for the given theme or an empty string if none is available. The theme must be one of **org.freedesktop.ratbag1.Manager.Themes**. The theme 'default' is guaranteed to be available. ratbagd may return the path to a file that doesn't exist. This is the case if the device has SVGs available but not for the given theme. org.freedesktop.ratbag1.Profile =============================== ### Properties: #### `Index` - type: `u`, read-only, constant The index of this profile #### `Enabled` - type: `b`, read-write, mutable True if this is the profile is enabled, false otherwise. Note that a disabled profile might not have correct bindings, so it's a good thing to rebind everything before calling `Commit()` on the **org.freedesktop.ratbag1.Device**. #### `Resolutions` - type: `ao`, read-only, mutable This property is mutable if the device supports adding and removing resolutions. Provides the object paths of all resolutions in this profile, see **org.freedesktop.ratbag1.Resolution** #### `Buttons` - type: `ao`, read-only, constant Provides the object paths of all buttons in this profile, see **org.freedesktop.ratbag1.Button** #### `Leds` - type: `ao`, read-only, constant Provides the object paths of all LEDs in this profile, see **org.freedesktop.ratbag1.Led** ### `IsActive` - type: `b`, read-only, mutable True if this is the currently active profile, false otherwise. Profiles can only be set to active, but never to not active - at least one profile must be active at all times. This property is read-only, use the `SetActive()` method to activate a profile. ### Methods: #### `SetActive() → ()` Set this profile to be the active profile org.freedesktop.ratbag1.Resolution ================================== ### Properties: #### `Index` - type: `u`, read-only, constant Index of the resolution #### `Capabilities` - type: `au`, read-only, constant Array of uints with the capabilities enum from libratbag #### `IsActive` - type: `b`, read-only, mutable True if this is the currently active resolution, false otherwise. Resolutions can only be set to active, but never to not active - at least one resoultion must be active at all times. This property is read-only, use the `SetActive()` method to set a resolution as the active resolution. #### `IsDefault` - type: `b`, read-only, mutable True if this is the currently default resolution, false otherwise. If the device does not have the default resolution capability, this property is always false. Resolutions can only be set to default, but never to not default - at least one resolution must be default at all times. This property is read-only, use the `SetDefault()` method to set a resolution as the default resolution. #### `Resolution` - type: `uu`, read-write, mutable uint for the x and y resolution assigned to this entry, respectively #### `ReportRate` - type: `u`, read-write, mutable uint for the report rate in Hz assigned to this entry #### `Maximum` - type: `u`, read-only, constant uint for the maximum possible resolution #### `Minimum` - type: `u`, read-only, constant uint for the minimum possible resolution ### Methods: #### `SetDefault() → () ` Set this resolution to be the default #### `SetActive() → () ` Set this resolution to be the active one org.freedesktop.ratbag1.Button ============================== ### Properties: #### `Index` - type: `u`, read-only, constant Index of the button #### `Type` - type: `u`, read-only, constant Enum describing the button physical type. This type is unrelated to the logical button mapping and serves to easily identify the button on the device. #### `ButtonMapping` - type: `u`, read-write, mutable uint of the current button mapping (if mapping to button) #### `SpecialMapping` - type: `u`, read-write, mutable Enum describing the current special mapping (if mapped to special) #### `Macro` -type: `a(uu)`, read-write, mutable Array of (type, keycode), where type may be one of `RATBAG_MACRO_EVENT_KEY_PRESSED` or `RATBAG_MACRO_EVENT_KEY_RELEASED`. #### `ActionType` - type: `u`, read-only, mutable An enum describing the action type of the button, see ratbag\_button\_get\_action\_type for the list of enums. This decides which *Mapping* property has a value. #### `ActionTypes` - type: `au`, read-only, constant Array of enum ratbag\_button\_action\_type, possible values for ActionType on the current device ### Methods: #### `Disable() → ()` Disable this button org.freedesktop.ratbag1.Led =========================== ### Properties: #### `Index` - type: `u`, read-only, constant Index of the LED #### `Mode` - type: `u`, read-write, mutable uint mapping to the mode enum from libratbag #### `Type` - type: `u`, read-only, mutable enum describing the LED type #### `Color` - type: `(uuu)`, read-write, mutable uint triplet (RGB) of the LED's color #### `EffectRate` - type: `u`, read-write, mutable The effect rate in Hz, possible values are in the range 100 - 20000 #### `Brightness` - type: `u`, read-write, mutable The brightness of the LED, possible values are in the range 0 - 255 For easier debugging, objects paths are constructed from the device. e.g. `/org/freedesktop/ratbag/button/event5/p0/b10` is the button interface for button 10 on profile 0 on event5. The naming is subject to change. Do not rely on a constructed object path in your application.
