Member Function Documentation

◆ get_capabilities()

Capabilities Gdk::Seat::get_capabilities ( ) const

Returns the capabilities this Gdk::Seat currently has.

Returns
The seat capabilities.

◆ get_display() [1/2]

Glib::RefPtr<Display> Gdk::Seat::get_display ( )

Returns the Gdk::Display this seat belongs to.

Returns
A Gdk::Display. This object is owned by GTK and must not be freed.

◆ get_display() [2/2]

Glib::RefPtr<const Display> Gdk::Seat::get_display ( ) const

Returns the Gdk::Display this seat belongs to.

Returns
A Gdk::Display. This object is owned by GTK and must not be freed.

◆ get_keyboard() [1/2]

Glib::RefPtr<Device> Gdk::Seat::get_keyboard ( )

Returns the master device that routes keyboard events.

Returns
A master Gdk::Device with keyboard capabilities. This object is owned by GTK and must not be freed.

◆ get_keyboard() [2/2]

Glib::RefPtr<const Device> Gdk::Seat::get_keyboard ( ) const

Returns the master device that routes keyboard events.

Returns
A master Gdk::Device with keyboard capabilities. This object is owned by GTK and must not be freed.

◆ get_master_pointers() [1/2]

std::vector<Glib::RefPtr<Device> > Gdk::Seat::get_master_pointers ( Capabilities  capabilities)

Returns all master pointers with the given capabilities driven by this seat.

On most backends this function will return a list with a single element (meaning that all input devices drive the same onscreen cursor).

In other backends where there can possibly be multiple foci (eg. wayland), this function will return all master Gdk::Devices that represent these.

Parameters
capabilitiesQueried capabilities.
Returns
A list of master pointing devices.

◆ get_master_pointers() [2/2]

std::vector<Glib::RefPtr<const Device> > Gdk::Seat::get_master_pointers ( Capabilities  capabilities) const

Returns all master pointers with the given capabilities driven by this seat.

On most backends this function will return a list with a single element (meaning that all input devices drive the same onscreen cursor).

In other backends where there can possibly be multiple foci (eg. wayland), this function will return all master Gdk::Devices that represent these.

Parameters
capabilitiesQueried capabilities.
Returns
A list of master pointing devices.

◆ get_pointer() [1/2]

Glib::RefPtr<Device> Gdk::Seat::get_pointer ( )

Returns the master device that routes pointer events.

Returns
A master Gdk::Device with pointer capabilities. This object is owned by GTK and must not be freed.

◆ get_pointer() [2/2]

Glib::RefPtr<const Device> Gdk::Seat::get_pointer ( ) const

Returns the master device that routes pointer events.

Returns
A master Gdk::Device with pointer capabilities. This object is owned by GTK and must not be freed.

◆ get_slaves() [1/2]

std::vector<Glib::RefPtr<Device> > Gdk::Seat::get_slaves ( Capabilities  capabilities)

Returns the slave devices that match the given capabilities.

Parameters
capabilitiesCapabilities to get devices for.
Returns
A list of Gdk::Devices.

◆ get_slaves() [2/2]

std::vector<Glib::RefPtr<const Device> > Gdk::Seat::get_slaves ( Capabilities  capabilities) const

Returns the slave devices that match the given capabilities.

Parameters
capabilitiesCapabilities to get devices for.
Returns
A list of Gdk::Devices.

◆ get_type()

static GType Gdk::Seat::get_type ( )
static

Get the GType for this class, for use with the underlying GObject type system.

◆ gobj() [1/2]

GdkSeat* Gdk::Seat::gobj ( )
inline

Provides access to the underlying C GObject.

◆ gobj() [2/2]

const GdkSeat* Gdk::Seat::gobj ( ) const
inline

Provides access to the underlying C GObject.

◆ gobj_copy()

Gdk::Display of this seat.

Returns
A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

◆ signal_device_added()

Glib::SignalProxy<void(const Glib::RefPtr<Device>&)> Gdk::Seat::signal_device_added ( )
Slot Prototype:
void on_my_device_added(const Glib::RefPtr<Device>& device)

Flags: Run Last

The signal_device_added() signal is emitted when a new input device is related to this seat.

Parameters
deviceThe newly added Gdk::Device.

◆ signal_device_removed()

Glib::SignalProxy<void(const Glib::RefPtr<Device>&)> Gdk::Seat::signal_device_removed ( )
Slot Prototype:
void on_my_device_removed(const Glib::RefPtr<Device>& device)

Flags: Run Last

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

Parameters
deviceThe just removed Gdk::Device.

◆ signal_tool_added()

Glib::SignalProxy<void(const Glib::RefPtr<DeviceTool>&)> Gdk::Seat::signal_tool_added ( )
Slot Prototype:
void on_my_tool_added(const Glib::RefPtr<DeviceTool>& device)

Flags: Run Last

The signal_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 Gdk::Device::signal_tool_changed() signal accordingly.

A same tool may be used by several devices.

Since gtkmm 3.94:
Parameters
deviceThe new Gdk::DeviceTool known to the seat.

◆ signal_tool_removed()

Glib::SignalProxy<void(const Glib::RefPtr<DeviceTool>&)> Gdk::Seat::signal_tool_removed ( )
Slot Prototype:
void on_my_tool_removed(const Glib::RefPtr<DeviceTool>& device)

Flags: Run Last

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

Since gtkmm 3.94:
Parameters
deviceThe just removed Gdk::DeviceTool.
