DragAndDrop system problem

Hello,
I am making my own drag and drop system in MyGUI. I listen for eventMouseDragged, then detach the widget and put it in the DragAndDrop layer. Then I move the widget so it stays centered on the cursor.

When I drag the widget over another one, it is impossible to know that I am over it since the widget that is dragging takes mouse focus. How can I fix this? Can I make the image follow the cursor without taking mouse focus?

Thanks,
Kukanani

partially fixed the problem by using

Widget* receiver = LayerManager::getInstance().getWidgetFromPoint(_left, _top);
receiver->eventMouseMove(image, _left, _top);


in eventMouseDragged for the dragged object. In eventMouseMove for the receiver I highlight the widget to show that you can drop the icon there.

However, I need to know when I am no longer over a widget (so I can make it not highlight).

DDContainer have such event, so you should either use it instead of receiver widget or create it as child of reciever widget. You probably need eventChangeDDState
