Underlying wl_proxy type and properties of a proxy_t that affect construction, destruction, and event handling

Enumerator

standard

C pointer is a standard type compatible with wl_proxy*. Events are dispatched and it is destructed when the proxy_t is destructed. User data is set.

display

C pointer is a wl_display*. No events are dispatched, wl_display_disconnect is called when the proxy_t is destructed. User data is set.

foreign

C pointer is a standard type compatible with wl_proxy*, but another library owns it and it should not be touched in a way that could affect the operation of the other library. No events are dispatched, wl_proxy_destroy is not called when the proxy_t is destructed, user data is not touched. Consequently, there is no reference counting for the proxy_t. Lifetime of such wrappers should preferably be short to minimize the chance that the owning library decides to destroy the wl_proxy.

proxy_wrapper

C pointer is a wl_proxy* that was constructed with wl_proxy_create_wrapper. No events are dispatched, wl_proxy_wrapper_destroy is called when the proxy_t is destroyed. Reference counting is active. A reference to the proxy_t creating this proxy wrapper is held to extend its lifetime until after the proxy wrapper is destroyed.

Definition at line 116 of file wayland-client.hpp.

Get a pointer to the underlying C struct.

Returns

The underlying wl_proxy wrapped by this proxy_t if it exists, otherwise an exception is thrown

Get the interface name (class) of a proxy object.

Returns

The interface name of the object associated with the proxy

Get the id of a proxy object.

Returns

The id the object associated with the proxy

Get the protocol object version of a proxy object. Gets the protocol object version of a proxy object, or 0 if the proxy was created with unversioned API.

A returned value of 0 means that no version information is available, so the caller must make safe assumptions about the object's real version.

display_t will always return version 0.

Returns

The protocol object version of the proxy or 0

Get the type of a proxy object.

new pad notification

Parameters

id the newly added pad

This event is sent whenever a new pad is known to the system. Typically, pads are physically attached to tablets and a pad_added event is sent immediately after the wp_tablet_seat.tablet_added. However, some standalone pad devices logically attach to tablets at runtime, and the client must wait for wp_tablet_pad.enter to know the tablet a pad is attached to.

This event only provides the object id of the pad. All further features (buttons, strips, rings) are sent through the wp_tablet_pad interface.

new device notification

Parameters

id the newly added graphics tablet

This event is sent whenever a new tablet becomes available on this seat. This event only provides the object id of the tablet, any static information about the tablet (device name, vid/pid, etc.) is sent through the wp_tablet interface.

Definition at line 7295 of file wayland-client-protocol-unstable.cpp.

a new tool has been used with a tablet

Parameters

id the newly added tablet tool

This event is sent whenever a tool that has not previously been used with a tablet comes into use. This event only provides the object id of the tool; any static information about the tool (capabilities, type, etc.) is sent through the wp_tablet_tool interface.

Definition at line 7300 of file wayland-client-protocol-unstable.cpp.

Check whether this wrapper actually wraps an object.

Returns

true if there is an underlying object, false if this wrapper is empty

Check whether two wrappers refer to different objects.

Check whether two wrappers refer to the same object.

Check whether this wrapper actually wraps an object.

Returns

true if there is an underlying object, false if this wrapper is empty

Release the wrapped object (if any), making this an empty wrapper. Note that display_t instances cannot be released this way. Attempts to do so are ignored.

Examples foreign_display.cpp.

Assign a proxy to an event queue.

Parameters

queue The event queue that will handle this proxy

Assign proxy to event queue. Events coming from proxy will be queued in queue instead of the display's main queue.
