Implementations

source

impl DragContext

source

pub fn actions(&self) -> DragAction

Determines the bitmask of actions proposed by the source if suggested_action() returns DragAction::ASK.

pub fn dest_window(&self) -> Window

Returns the destination window for the DND operation.

pub fn device(&self) -> Device

Returns the Device associated to the drag context.

Returns

The Device associated to self.

source

pub fn drag_window(&self) -> Option<Window>

Available on crate feature v3_20 only.

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 self and will be destroyed when the drag operation is over.

Returns

the drag window, or None

source

pub fn protocol(&self) -> DragProtocol

Returns the drag protocol that is used by this context.

Returns

the drag protocol

source

pub fn selected_action(&self) -> DragAction

Determines the action chosen by the drag destination.

Returns

a DragAction value

source

pub fn source_window(&self) -> Window

Returns the Window where the DND operation started.

Returns

a Window

source

pub fn suggested_action(&self) -> DragAction

Determines the suggested drag action of the context.

Returns

a DragAction value

source

pub fn list_targets(&self) -> Vec<Atom>

Retrieves the list of targets of the context.

Returns

a GList of targets

source

pub fn manage_dnd(&self, ipc_window: &Window, actions: DragAction) -> bool

Available on crate feature v3_20 only.

Requests the drag and drop operation to be managed by self. 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 signal::DragContext::action-changed signal whenever the final action to be performed by the drag and drop operation changes.
The signal::DragContext::drop-performed signal after the user performs the drag and drop gesture (typically by releasing the mouse button).
The signal::DragContext::dnd-finished signal after the drag and drop operation concludes (after all GdkSelection transfers happen).
The signal::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.

`ipc_window`

Window to use for IPC messaging/events

`actions`

the actions supported by the drag source

Returns

true if the drag and drop operation is managed.

source

pub fn set_device(&self, device: &Device)

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

`device`

a Device

source

pub fn set_hotspot(&self, hot_x: i32, hot_y: i32)

Available on crate feature v3_20 only.

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.

`hot_x`

x coordinate of the drag window hotspot

`hot_y`

y coordinate of the drag window hotspot

source

pub fn connect_action_changed<F: Fn(&Self, DragAction) + 'static>(
&self,
f: F
) -> SignalHandlerId

Available on crate feature v3_20 only.

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 manage_dnd() for more information.

source

pub fn connect_dnd_finished<F: Fn(&Self) + 'static>(
&self,
f: F
) -> SignalHandlerId

Available on crate feature v3_20 only.

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 manage_dnd() for more information.

source

pub fn connect_drop_performed<F: Fn(&Self, i32) + 'static>(
&self,
f: F
) -> SignalHandlerId
