Detailed Description
DataDevice allows clients to share data by copy-and-paste and drag-and-drop.
This class is a convenient wrapper for the wl_data_device interface. To create a DataDevice call DataDeviceManager::getDataDevice.

Member Function Documentation
◆ destroy()
void KWayland::Client::DataDevice::destroy | ( | ) |
Destroys the data held by this DataDevice.
This method is supposed to be used when the connection to the Wayland server goes away. If the connection is not valid anymore, it's not possible to call release anymore as that calls into the Wayland connection and the call would fail. This method cleans up the data, so that the instance can be deleted or set up to a new wl_data_device interface once there is a new connection available.
This method is automatically invoked when the Registry which created this DataDevice gets destroyed.

- release
Definition at line 167 of file datadevice.cpp.
◆ dragEntered
|
signal |
Notification that a drag'n'drop operation entered a Surface on this DataDevice.
- Parameters
-
serial The serial for this enter relativeToSurface Coordinates relative to the upper-left corner of the Surface.
- See also
- dragSurface
- dragOffer
- dragLeft
- dragMotion
- Since
- 5.22
◆ dragLeft
|
signal |
Notification that the drag'n'drop operation left the Surface on this DataDevice.
The leave notification is sent before the enter notification for the new focus.
- See also
- dragEnter
- Since
- 5.22
◆ dragMotion
|
signal |
Notification of drag motion events on the current drag surface.
- Parameters
-
relativeToSurface Coordinates relative to the upper-left corner of the entered Surface. time timestamp with millisecond granularity
- See also
- dragEntered
- Since
- 5.22
◆ dragOffer()
DataOffer * KWayland::Client::DataDevice::dragOffer | ( | ) | const |
- Returns
- the DataOffer during a drag'n'drop operation.
- Since
- 5.22
Definition at line 228 of file datadevice.cpp.
◆ dragSurface()
- Returns
- the currently focused surface during drag'n'drop on this DataDevice.
- Since
- 5.22
Definition at line 223 of file datadevice.cpp.
◆ dropped
|
signal |
Emitted when the implicit grab is removed and the drag'n'drop operation ended on this DataDevice.
The client can now start a data transfer on the DataOffer.
- See also
- dragEntered
- dragOffer
- Since
- 5.22
◆ isValid()
bool KWayland::Client::DataDevice::isValid | ( | ) | const |
- Returns
true
if managing a wl_data_device.
Definition at line 177 of file datadevice.cpp.
◆ release()
void KWayland::Client::DataDevice::release | ( | ) |
Releases the wl_data_device interface.
After the interface has been released the DataDevice instance is no longer valid and can be setup with another wl_data_device interface.
Definition at line 172 of file datadevice.cpp.
◆ setup()
void KWayland::Client::DataDevice::setup | ( | wl_data_device * | dataDevice | ) |
Setup this DataDevice to manage the dataDevice
.
When using DataDeviceManager::createDataDevice there is no need to call this method.
