Struct rute::auto::drag_move_event::DragMoveEvent

pub struct DragMoveEvent<'a> { /* private fields */ }

Notice these docs are heavy WIP and not very relevent yet

A widget will receive drag move events repeatedly while the drag is within its boundaries, if it accepts drop events and enter events . The widget should examine the event to see what kind of data it provides, and call the accept() function to accept the drop if appropriate.

The rectangle supplied by the answerRect() function can be used to restrict drops to certain parts of the widget. For example, we can check whether the rectangle intersects with the geometry of a certain child widget and only call acceptProposedAction() if that is the case.

Note that this class inherits most of its functionality from QDropEvent.

Implementations

impl<'a> DragMoveEvent<'a>

pub fn answer_rect(&self) -> Rect<'_>

Returns the rectangle in the widget where the drop will occur if accepted. You can use this information to restrict drops to certain places on the widget.

pub fn accept(&self) -> &Self

The same as accept(), but also notifies that future moves will also be acceptable if they remain within the rectangle given on the widget. This can improve performance, but may also be ignored by the underlying system.

If the rectangle is empty, drag move events will be sent continuously. This is useful if the source is scrolling in a timer event.

Overloads Calls QDropEvent::accept().

pub fn ignore(&self) -> &Self

Overloads Calls QDropEvent::ignore().

The opposite of the accept(const QRect&) function. Moves within the rectangle are not acceptable, and will be ignored.

pub fn accept_2<R: RectTrait<'a>>(&self, r: &R) -> &Self

The same as accept(), but also notifies that future moves will also be acceptable if they remain within the rectangle given on the widget. This can improve performance, but may also be ignored by the underlying system.

If the rectangle is empty, drag move events will be sent continuously. This is useful if the source is scrolling in a timer event.

Overloads Calls QDropEvent::accept().

pub fn ignore_2<R: RectTrait<'a>>(&self, r: &R) -> &Self

Overloads Calls QDropEvent::ignore().

The opposite of the accept(const QRect&) function. Moves within the rectangle are not acceptable, and will be ignored.

Trait Implementations

impl<'a> Clone for DragMoveEvent<'a>

fn clone(&self) -> DragMoveEvent<'a>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
