DragEnter in GraphicsView

[rogerholmes]

GraphicsScene *scene =new GraphicsScene(this);

scene->setBackgroundBrush(Qt::red);

myView *gView = new myView(this);
gView->setGeometry(230,20,330,400);

//gView->installEventFilter(this);

gView->setScene(scene);
gView->setSceneRect(0,0,100,100);

gView->setAcceptDrops(true);

i am only able to drop in the right most 1/4 of the view ,i have try'd using QGraphicsview insted of myView , same result. the dragenter will not fire until the right most 1/4 is entered. i am sure i am missing something quite obvious but have read everything i could find pls can somebody point me in right direction.

Your scene occupies only part of the view - the drops can only occur on the scene, so you get the event not when you enter the viewport but when you enter the rect occupied by the scene.

Thanks, I thought that was the case , so i colored the scene red , when i setscene(scene), the whole view is red, there are no scroll-bars so i know the scene is smaller than the viewport and the entire view is red, the dropenter is on the myview because i read that this would go through to the scene, am i right in thinking if the scene was not centered, only part of the view would be red and by setting the dragenter/drop etc.. on the myview, wouldn't the event fire when the myview is entered regardless of setting a scene or not? ( i forgot to mention, the myview reacts the same when a scene is not set, only the right 1/4 of the myview fires the dragenter event)

Do something else. Add a rectangle item occupying the whole scene.

No, that's wrong. See the idea above.


and by setting the dragenter/drop etc.. on the myview, wouldn't the event fire when the myview is entered regardless of setting a scene or not?
It fires on the graphicsview's viewport and is immediately intercepted by the event filter the view applies on its viewport.


( i forgot to mention, the myview reacts the same when a scene is not set, only the right 1/4 of the myview fires the dragenter event)
That I do not know, maybe that's the way it works if a scene is not set on the view.
