[SOLVED] Tracking mouse move in a QGraphicsItem subclass

[isaacEnrique]

Greetings.

I'm implementing event handlers in a subclass of QGraphicsItem. Under certain circumstances (defined by a flag values​​) I want that the cursor changes its shape (Qt::SizeVerCursor, Qt::SizeHorCursor, Qt::SizeBDiagCursor, Qt::SizeFDiagCursor and Qt::ArrowCursor) when being moved (without any mouse button being pressed) to certain parts of my QGraphicsItem subclass.

I would like some idea about it, particularly as thought I can do to "activate" or "simulate" functionality similar to QWidget::setMouseTracking(bool enable), but for QGraphicsItem... I think I need it to perform the task arising above.

Thanks for any help and/or suggestions.

Hi,

you should have a look at setAcceptHoverEvents and friends from QGraphicsItem

Hope it helps

Thanks for the advice SGaist.

I put 'setAcceptsHoverEvents (true)' and implement event handlers

 void hoverEnterEvent (QGraphicsSceneHoverEvent * event);
 void hoverMoveEvent (QGraphicsSceneHoverEvent * event);
 void hoverLeaveEvent (QGraphicsSceneHoverEvent * event);

And I achieved complete the task.
