Memory-managed wrapper type.

Type class for types which can be safely cast to DragContext, for instance with toDragContext.

Cast to DragContext, for types for which this is known to be safe. For general casts, use castTo.

A convenience alias for Nothing :: Maybe DragContext.

Determines the bitmask of actions proposed by the source if dragContextGetSuggestedAction returns DragActionAsk.

Since: 2.22

Returns the destination windw for the DND operation.

Since: 3.0

Returns the Device associated to the drag context.

Returns the window on which the drag icon should be rendered during the drag operation. Note that the window may not be available until the drag operation has begun. GDK will move the window in accordance with the ongoing drag operation. The window is owned by context and will be destroyed when the drag operation is over.

Since: 3.20

Returns the drag protocol thats used by this context.

Since: 3.0

Determines the action chosen by the drag destination.

Since: 2.22

Returns the Window where the DND operation started.

Since: 2.22

Determines the suggested drag action of the context.

Since: 2.22

Retrieves the list of targets of the context.

Since: 2.22

Requests the drag and drop operation to be managed by context. When a drag and drop operation becomes managed, the DragContext will internally handle all input and source-side EventDND events as required by the windowing system.

Once the drag and drop operation is managed, the drag context will emit the following signals:

• The DragContext::action-changed signal whenever the final action to be performed by the drag and drop operation changes.
• The DragContext::drop-performed signal after the user performs the drag and drop gesture (typically by releasing the mouse button).
• The DragContext::dnd-finished signal after the drag and drop operation concludes (after all GdkSelection transfers happen).
• The DragContext::cancel signal if the drag and drop operation is finished but doesn't happen over an accepting destination, or is cancelled through other means.

Since: 3.20

Associates a Device to context, so all Drag and Drop events for context are emitted as if they came from this device.

Sets the position of the drag window that will be kept under the cursor hotspot. Initially, the hotspot is at the top left corner of the drag window.

Since: 3.20

Type for the callback on the (unwrapped) C side.

A new action is being chosen for the drag and drop operation.

This signal will only be emitted if the DragContext manages the drag and drop operation. See dragContextManageDnd for more information.

Since: 3.20

Connect a signal handler for the “action-changed” signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after dragContext #actionChanged callback

Wrap the callback into a Closure.

Generate a function pointer callable from C code, from a C_DragContextActionChangedCallback.

A convenience synonym for Nothing :: Maybe DragContextActionChangedCallback.

Connect a signal handler for the “action-changed” signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on dragContext #actionChanged callback

Wrap a DragContextActionChangedCallback into a C_DragContextActionChangedCallback.

Type for the callback on the (unwrapped) C side.

The drag and drop operation was cancelled.

This signal will only be emitted if the DragContext manages the drag and drop operation. See dragContextManageDnd for more information.

Since: 3.20

Connect a signal handler for the “cancel” signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after dragContext #cancel callback

Wrap the callback into a Closure.

Generate a function pointer callable from C code, from a C_DragContextCancelCallback.

A convenience synonym for Nothing :: Maybe DragContextCancelCallback.

Connect a signal handler for the “cancel” signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on dragContext #cancel callback

Wrap a DragContextCancelCallback into a C_DragContextCancelCallback.

Type for the callback on the (unwrapped) C side.

The drag and drop operation was finished, the drag destination finished reading all data. The drag source can now free all miscellaneous data.

This signal will only be emitted if the DragContext manages the drag and drop operation. See dragContextManageDnd for more information.

Since: 3.20

Connect a signal handler for the “dnd-finished” signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after dragContext #dndFinished callback

Wrap the callback into a Closure.

Generate a function pointer callable from C code, from a C_DragContextDndFinishedCallback.

A convenience synonym for Nothing :: Maybe DragContextDndFinishedCallback.

Connect a signal handler for the “dnd-finished” signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on dragContext #dndFinished callback

Wrap a DragContextDndFinishedCallback into a C_DragContextDndFinishedCallback.

Type for the callback on the (unwrapped) C side.

The drag and drop operation was performed on an accepting client.

This signal will only be emitted if the DragContext manages the drag and drop operation. See dragContextManageDnd for more information.

Since: 3.20

Connect a signal handler for the “drop-performed” signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after dragContext #dropPerformed callback

Wrap the callback into a Closure.

Generate a function pointer callable from C code, from a C_DragContextDropPerformedCallback.

A convenience synonym for Nothing :: Maybe DragContextDropPerformedCallback.

Connect a signal handler for the “drop-performed” signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on dragContext #dropPerformed callback

Wrap a DragContextDropPerformedCallback into a C_DragContextDropPerformedCallback.
