Trait containing all Drag methods.

Implementors

Drag

Required Methods

Informs GDK that the drop ended.

Passing false for @success may trigger a drag cancellation animation.

This function is called by the drag source, and should be the last call before dropping the reference to the @self.

The Drag will only take the first drop_done() call as effective, if this function is called multiple times, all subsequent calls will be ignored.

success

whether the drag was ultimatively successful

Determines the bitmask of possible actions proposed by the source.

Returns

the DragAction flags

Returns the ContentProvider associated to the Drag object.

Returns

The ContentProvider associated to @self.

Returns the Device associated to the Drag object.

Returns

The Device associated to @self.

Gets the Display that the drag object was created for.

Returns

a Display

Returns the surface on which the drag icon should be rendered during the drag operation.

Note that the surface may not be available until the drag operation has begun. GDK will move the surface in accordance with the ongoing drag operation. The surface is owned by @self and will be destroyed when the drag operation is over.

Returns

the drag surface

Retrieves the formats supported by this Drag object.

Returns

a ContentFormats

Determines the action chosen by the drag destination.

Returns

a DragAction value

Returns the Surface where the drag originates.

Returns

The Surface where the drag originates

Sets the position of the drag surface that will be kept under the cursor hotspot.

Initially, the hotspot is at the top left corner of the drag surface.

hot_x

x coordinate of the drag surface hotspot

hot_y

y coordinate of the drag surface hotspot

The possible actions of this drag.

The currently selected action of the drag.

Emitted when the drag operation is cancelled.

reason

The reason the drag was cancelled

Emitted when the destination side has finished reading all data.

The drag object can now free all miscellaneous data.

Emitted when the drop operation is performed on an accepting client.
