Struct rute::auto::drop_event::DropEvent
source · pub struct DropEvent<'a> { /* private fields */ }Expand description
Notice these docs are heavy WIP and not very relevent yet
When a widget accepts drop events , it will receive this event if it has accepted the most recent QDragEnterEvent or QDragMoveEvent sent to it.
The drop event contains a proposed action, available from proposedAction(), for the widget to either accept or ignore. If the action can be handled by the widget, you should call the acceptProposedAction() function. Since the proposed action can be a combination of Qt::DropAction values, it may be useful to either select one of these values as a default action or ask the user to select their preferred action.
If the proposed drop action is not suitable, perhaps because your custom widget does not support that action, you can replace it with any of the possible drop actions by calling setDropAction() with your preferred action. If you set a value that is not present in the bitwise OR combination of values returned by possibleActions(), the default copy action will be used. Once a replacement drop action has been set, call accept() instead of acceptProposedAction() to complete the drop operation.
The mimeData() function provides the data dropped on the widget in a QMimeData object. This contains information about the MIME type of the data in addition to the data itself.

Implementations
sourceimpl<'a> DropEvent<'a>
impl<'a> DropEvent<'a>
sourcepub fn pos(&self) -> Point<'_>
pub fn pos(&self) -> Point<'_>
Returns the position where the drop was made.
See also: [drop_action()]
Returns the mouse buttons that are pressed..
sourcepub fn keyboard_modifiers(&self) -> KeyboardModifiers
pub fn keyboard_modifiers(&self) -> KeyboardModifiers
Returns the modifier keys that are pressed.
sourcepub fn possible_actions(&self) -> DropActions
pub fn possible_actions(&self) -> DropActions
Returns an OR-combination of possible drop actions.
See also: [drop_action()]
sourcepub fn proposed_action(&self) -> DropAction
pub fn proposed_action(&self) -> DropAction
Returns the proposed drop action.
See also: [drop_action()]
sourcepub fn accept_proposed_action(&self) -> &Self
pub fn accept_proposed_action(&self) -> &Self
Sets the drop action to be the proposed action.
See also: [set_drop_action()]
[proposed_action()]
{QEvent::accept()}{accept()}
sourcepub fn drop_action(&self) -> DropAction
pub fn drop_action(&self) -> DropAction
Returns the action to be performed on the data by the target. This may be different from the action supplied in proposedAction() if you have called setDropAction() to explicitly choose a drop action.
See also: [set_drop_action()]
sourcepub fn set_drop_action(&self, action: DropAction) -> &Self
pub fn set_drop_action(&self, action: DropAction) -> &Self
Sets the action to be performed on the data by the target. Use this to override the proposed action
with one of the possible actions
If you set a drop action that is not one of the possible actions, the drag and drop operation will default to a copy operation.
Once you have supplied a replacement drop action, call accept() instead of acceptProposedAction().
See also: [drop_action()]
sourcepub fn source(&self) -> Option<Object<'_>>
pub fn source(&self) -> Option<Object<'_>>
If the source of the drag operation is a widget in this application, this function returns that source; otherwise it returns 0. The source of the operation is the first parameter to the QDrag object used instantiate the drag.
This is useful if your widget needs special behavior when dragging to itself.

sourcepub fn mime_data(&self) -> Option<MimeData<'_>>
pub fn mime_data(&self) -> Option<MimeData<'_>>
Returns the data that was dropped on the widget and its associated MIME type information.
