Member Function Documentation

◆ mouseDobleClicked

void MouseInterceptingGraphicsScene::mouseDobleClicked ( )

signal

Here is the caller graph for this function:

◆ mouseDoubleClickEvent()

void MouseInterceptingGraphicsScene::mouseDoubleClickEvent ( QGraphicsSceneMouseEvent * mouseEvent )

protectedvirtual

This event handler, for event mouseEvent, can be reimplemented in a subclass to receive mouse double-click events for the scene.

If someone doubleclicks on the scene, the scene will first receive a mouse press event, followed by a release event (i.e., a click), then a double-click event, and finally a release event. If the double-click event is delivered to a different item than the one that received the first press and release, it will be delivered as a press event. However, tripleclick events are not delivered as double-click events in this case.

The default implementation is similar to mousePressEvent().

Note: See items() for a definition of which items are considered visible by this function.

See also: QGraphicsItem::mousePressEvent(), QGraphicsItem::mouseMoveEvent(), QGraphicsItem::mouseReleaseEvent(), QGraphicsItem::setAcceptedMouseButtons()

Here is the call graph for this function:

◆ mousePressed

void MouseInterceptingGraphicsScene::mousePressed ( const QPoint point )

signal

Here is the caller graph for this function:

◆ mousePressEvent()

void MouseInterceptingGraphicsScene::mousePressEvent ( QGraphicsSceneMouseEvent * mouseEvent )

protectedvirtual

This event handler, for event mouseEvent, can be reimplemented in a subclass to receive mouse press events for the scene.

The default implementation depends on the state of the scene. If there is a mouse grabber item, then the event is sent to the mouse grabber. Otherwise, it is forwarded to the topmost visible item that accepts mouse events at the scene position from the event, and that item promptly becomes the mouse grabber item.

If there is no item at the given position on the scene, the selection area is reset, any focus item loses its input focus, and the event is then ignored.

Note: See items() for a definition of which items are considered visible by this function.
