## Detailed Description

touchpad gestures

A global interface to provide semantic touchpad gestures for a given pointer.

Three gestures are currently supported: swipe, pinch, and hold. Pinch and swipe gestures follow a three-stage cycle: begin, update, end, hold gestures follow a two-stage cycle: begin and end. All gestures are identified by a unique id.

Warning! The protocol described in this file is experimental and backward incompatible changes may be made. Backward compatible changes may be added together with the corresponding interface version bump. Backward incompatible changes are done by bumping the version number in the protocol and interface names and resetting the interface version. Once the protocol is to be declared stable, the 'z' prefix and the version number in the protocol and interface names are removed and the interface version number is reset.

## Member Function Documentation

### std::string wayland::server::resource\_t::get\_class ()` [inherited]`

Retrieve the interface name (class) of a resource object.

**Returns**

Interface name of the resource object.

### client\_t wayland::server::resource\_t::get\_client () const` [inherited]`

Get the associated client

**Returns**

the client that owns the resource.

### uint32\_t wayland::server::resource\_t::get\_id () const` [inherited]`

Get the internal ID of the resource

**Returns**

the internal ID of the resource

### unsigned int wayland::server::resource\_t::get\_version () const` [inherited]`

Get interface version

**Returns**

Interface version this resource has been constructed with.

### std::function\< void(zwp\_pointer\_gesture\_hold\_v1\_t, pointer\_t)\> & zwp\_pointer\_gestures\_v1\_t::on\_get\_hold\_gesture ()

get hold gesture

**Parameters**

*id* \
 *pointer*

Create a hold gesture object. See the wl\_pointer\_gesture\_hold interface for details.

Definition at line **5571** of file **wayland-server-protocol-unstable.cpp**.

### std::function\< void(zwp\_pointer\_gesture\_pinch\_v1\_t, pointer\_t)\> & zwp\_pointer\_gestures\_v1\_t::on\_get\_pinch\_gesture ()

get pinch gesture

**Parameters**

*id* \
 *pointer*

Create a pinch gesture object. See the wl\_pointer\_gesture\_pinch interface for details.

Definition at line **5559** of file **wayland-server-protocol-unstable.cpp**.

### std::function\< void(zwp\_pointer\_gesture\_swipe\_v1\_t, pointer\_t)\> & zwp\_pointer\_gestures\_v1\_t::on\_get\_swipe\_gesture ()

get swipe gesture

**Parameters**

*id* \
 *pointer*

Create a swipe gesture object. See the wl\_pointer\_gesture\_swipe interface for details.

Definition at line **5553** of file **wayland-server-protocol-unstable.cpp**.

### std::function\< void()\> & zwp\_pointer\_gestures\_v1\_t::on\_release ()

destroy the pointer gesture object Destroy the pointer gesture object. Swipe, pinch and hold objects created via this gesture object remain valid.

Definition at line **5565** of file **wayland-server-protocol-unstable.cpp**.

### void wayland::server::resource\_t::post\_no\_memory () const` [inherited]`

Post 'not enough memory' error to the client

If the compositor has not enough memory to fulfill a certail request of the client, this function can be called to notify the client of this circumstance.

### bool wayland::server::resource\_t::proxy\_has\_object () const` [inherited]`

Check whether this wrapper actually wraps an object.

**Returns**

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