[−]Struct gdk::DragContext
Implementations
impl DragContext[src]
pub fn get_actions(&self) -> DragAction[src]
Determines the bitmask of actions proposed by the source if
DragContext::get_suggested_action returns DragAction::Ask.
Returns
the DragAction flags
pub fn get_dest_window(&self) -> Window[src]
pub fn get_device(&self) -> Device[src]
pub fn get_drag_window(&self) -> Option<Window>[src]
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.
Feature: v3_20
Returns
the drag window, or None
pub fn get_protocol(&self) -> DragProtocol[src]
pub fn get_selected_action(&self) -> DragAction[src]
pub fn get_source_window(&self) -> Window[src]
pub fn get_suggested_action(&self) -> DragAction[src]
pub fn list_targets(&self) -> Vec<Atom>[src]
pub fn manage_dnd<P: IsA<Window>>(
&self,
ipc_window: &P,
actions: DragAction
) -> bool[src]
&self,
ipc_window: &P,
actions: DragAction
) -> bool
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
DragContext::action-changedsignal whenever the final action to be performed by the drag and drop operation changes. - The
DragContext::drop-performedsignal after the user performs the drag and drop gesture (typically by releasing the mouse button). - The
DragContext::dnd-finishedsignal after the drag and drop operation concludes (after allGdkSelectiontransfers happen). - The
DragContext::cancelsignal if the drag and drop operation is finished but doesn't happen over an accepting destination, or is cancelled through other means.
Feature: v3_20
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.
pub fn set_device(&self, device: &Device)[src]
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
pub fn set_hotspot(&self, hot_x: i32, hot_y: i32)[src]
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.
Feature: v3_20
hot_x
x coordinate of the drag window hotspot
hot_y
y coordinate of the drag window hotspot
pub fn connect_action_changed<F: Fn(&DragContext, DragAction) + 'static>(
&self,
f: F
) -> SignalHandlerId[src]
&self,
f: F
) -> SignalHandlerId
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 DragContext::manage_dnd
for more information.
Feature: v3_20
action
The action currently chosen
pub fn connect_cancel<F: Fn(&DragContext, DragCancelReason) + 'static>(
&self,
f: F
) -> SignalHandlerId[src]
&self,
f: F
) -> SignalHandlerId
The drag and drop operation was cancelled.
This signal will only be emitted if the DragContext manages
the drag and drop operation. See DragContext::manage_dnd
for more information.
Feature: v3_20
reason
The reason the context was cancelled
pub fn connect_dnd_finished<F: Fn(&DragContext) + 'static>(
&self,
f: F
) -> SignalHandlerId[src]
&self,
f: F
) -> SignalHandlerId
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 DragContext::manage_dnd
for more information.
Feature: v3_20
pub fn connect_drop_performed<F: Fn(&DragContext, i32) + 'static>(
&self,
f: F
) -> SignalHandlerId[src]
&self,
f: F
) -> SignalHandlerId
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 DragContext::manage_dnd
for more information.
Feature: v3_20
time
the time at which the drop happened.
