Detailed Description
controller object for graphic tablet devices
An object that provides access to the graphics tablets available on this system. All tablets are associated with a seat, to get access to the actual tablets, use wp_tablet_manager.get_tablet_seat.

◆ wrapper_type
|
stronginherited |
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. |

Member Function Documentation
◆ c_ptr()
|
inherited |
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_class()
|
inherited |
Get the interface name (class) of a proxy object.
- Returns
- The interface name of the object associated with the proxy
◆ get_id()
|
inherited |
◆ get_tablet_seat()
| zwp_tablet_seat_v1_t zwp_tablet_manager_v1_t::get_tablet_seat | ( | seat_t | seat | ) |
get the tablet seat
- Parameters
-
seat The wl_seat object to retrieve the tablets for
Get the wp_tablet_seat object for the given seat. This object provides access to all graphics tablets in this seat.
Definition at line 6217 of file wayland-client-protocol-unstable.cpp.
◆ get_version()
|
inherited |
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_wrapper_type()
|
inlineinherited |
Get the type of a proxy object.
Definition at line 288 of file wayland-client.hpp.
◆ operator bool()
|
inherited |
Check whether this wrapper actually wraps an object.
- Returns
- true if there is an underlying object, false if this wrapper is empty
◆ operator!=()
|
inherited |
Check whether two wrappers refer to different objects.
◆ operator==()
|
inherited |
Check whether two wrappers refer to the same object.
◆ proxy_has_object()
|
inherited |
Check whether this wrapper actually wraps an object.
- Returns
- true if there is an underlying object, false if this wrapper is empty
◆ proxy_release()
|
inherited |
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.
◆ set_queue()
|
inherited |
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.
See also: display_t::dispatch_queue().
- Examples
- proxy_wrapper.cpp.
