Implementations

source

impl Seat

source

pub fn capabilities(&self) -> SeatCapabilities

Available on crate feature v3_20 only.

Returns the capabilities this Seat currently has.

pub fn display(&self) -> Option<Display>

Available on crate feature v3_20 only.

Returns the Display this seat belongs to.

Returns

a Display. This object is owned by GTK+ and must not be freed.

source

pub fn keyboard(&self) -> Option<Device>

Available on crate feature v3_20 only.

Returns the master device that routes keyboard events.

Returns

a master Device with keyboard capabilities. This object is owned by GTK+ and must not be freed.

source

pub fn pointer(&self) -> Option<Device>

Available on crate feature v3_20 only.

Returns the master device that routes pointer events.

Returns

a master Device with pointer capabilities. This object is owned by GTK+ and must not be freed.

source

pub fn slaves(&self, capabilities: SeatCapabilities) -> Vec<Device>

Available on crate feature v3_20 only.

Returns the slave devices that match the given capabilities.

Returns

A list of GdkDevices. The list must be freed with g_list_free(), the elements are owned by GDK and must not be freed.

source

pub fn grab(
 &self,
 window: &Window,
 capabilities: SeatCapabilities,
 owner_events: bool,
 cursor: Option<&Cursor>,
 event: Option<&Event>,
 prepare_func: Option<&mut dyn FnMut(&Seat, &Window)>
) -> GrabStatus

Available on crate feature v3_20 only.

Grabs the seat so that all events corresponding to the given capabilities are passed to this application until the seat is ungrabbed with ungrab(), or the window becomes hidden. This overrides any previous grab on the seat by this client.

As a rule of thumb, if a grab is desired over SeatCapabilities::POINTER, all other “pointing” capabilities (eg. SeatCapabilities::TOUCH) should be grabbed too, so the user is able to interact with all of those while the grab holds, you should thus use SeatCapabilities::ALL_POINTING most commonly.

Grabs are used for operations which need complete control over the events corresponding to the given capabilities. For example in GTK+ this is used for Drag and Drop operations, popup menus and such.

Note that if the event mask of a Window has selected both button press and button release events, or touch begin and touch end, then a press event will cause an automatic grab until the button is released, equivalent to a grab on the window with owner_events set to true. This is done because most applications expect to receive paired press and release events.

If you set up anything at the time you take the grab that needs to be cleaned up when the grab ends, you should handle the EventGrabBroken events that are emitted when the grab ends unvoluntarily.

`window`

the Window which will own the grab

`capabilities`

capabilities that will be grabbed

`owner_events`

if false then all device events are reported with respect to window and are only reported if selected by event_mask. If true then pointer events for this application are reported as normal, but pointer events outside this application are reported with respect to window and only if selected by event_mask. In either mode, unreported events are discarded.

`cursor`

the cursor to display while the grab is active. If this is None then the normal cursors are used for window and its descendants, and the cursor for window is used elsewhere.

`event`

the event that is triggering the grab, or None if none is available.

`prepare_func`

function to prepare the window to be grabbed, it can be None if window is visible before this call.

`prepare_func_data`

user data to pass to prepare_func

Returns

GrabStatus::Success if the grab was successful.

source

pub fn ungrab(&self)

Available on crate feature v3_20 only.

Releases a grab added through grab().

source

pub fn connect_device_added<F: Fn(&Self, &Device) + 'static>(
&self,
f: F
) -> SignalHandlerId

Available on crate feature v3_20 only.

The ::device-added signal is emitted when a new input device is related to this seat.

`device`

the newly added Device.

source

pub fn connect_device_removed<F: Fn(&Self, &Device) + 'static>(
&self,
f: F
) -> SignalHandlerId

Available on crate feature v3_20 only.

The ::device-removed signal is emitted when an input device is removed (e.g. unplugged).

`device`

the just removed Device.

source

pub fn connect_tool_added<F: Fn(&Self, &DeviceTool) + 'static>(
&self,
f: F
) -> SignalHandlerId

Available on crate features v3_20 and v3_22 only.

The ::tool-added signal is emitted whenever a new tool is made known to the seat. The tool may later be assigned to a device (i.e. on proximity with a tablet). The device will emit the signal::Device::tool-changed signal accordingly.

A same tool may be used by several devices.

`tool`

the new DeviceTool known to the seat

source

pub fn connect_tool_removed<F: Fn(&Self, &DeviceTool) + 'static>(
&self,
f: F
) -> SignalHandlerId

Available on crate features v3_20 and v3_22 only.

This signal is emitted whenever a tool is no longer known to this seat.

`tool`

the just removed DeviceTool
