Struct Drag

Source
pub struct Drag { /* private fields */ }
Expand description

The Drag object represents the source of an ongoing DND operation.

A Drag is created when a drag is started, and stays alive for duration of the DND operation. After a drag has been started with begin(), the caller gets informed about the status of the ongoing drag operation with signals on the Drag object.

GTK provides a higher level abstraction based on top of these functions, and so they are not normally needed in GTK applications. See the “Drag and Drop” section of the GTK documentation for more information.

This is an Abstract Base Class, you cannot instantiate it.

Implementations§

Source§

impl Drag

Source

pub const NONE: Option<&'static Drag> = None

Source

pub fn begin( surface: &impl IsA<Surface>, device: &impl IsA<Device>, content: &impl IsA<ContentProvider>, actions: DragAction, dx: f64, dy: f64, ) -> Option<Drag>

Starts a drag and creates a new drag context for it.

This function is called by the drag source. After this call, you probably want to set up the drag icon using the surface returned by DragExt::drag_surface().

This function returns a reference to the Drag object, but GTK keeps its own reference as well, as long as the DND operation is going on.

Note: if @actions include DragAction::MOVE, you need to listen for the dnd-finished signal and delete the data at the source if DragExt::selected_action() returns DragAction::MOVE.

§surface

the source surface for this drag

§device

the device that controls this drag

§content

the offered content

§actions

the actions supported by this drag

§dx

the x offset to @device’s position where the drag nominally started

§dy

the y offset to @device’s position where the drag nominally started

§Returns

a newly created Drag
