Drag & drop items collide..

[cCj]

Hi
have this problem with drag & Drop that if i drop item to another item then OnDropped event wont be called as the item drops off the drag container.

i tried to solve this by setting all the drag items to pass through mouse clicks but then they cannot be dragged.


i think CEGUI needs improvement in this regards. Because now u can basically only drag & drop items to drag containers wich dont already have D&D item in them.

this problem is in v 0.7.4

Maybe some one knows the best way to get around this?

thx

Well the issue is, what do you do if a person wants to be able to drag & drop to another drag container? We can't just blithely ignore the fact there is some other window in the middle there, nor is it correct to always propagate back to the parent if the child returns false for isDragDropTarget. Adding a setting for every conceivable combination is also not something that we really want to be doing, since it soon gets out of hand (indeed, we may already go too far in this department).

In my opinion, the correct solution is to have your DragContainer handle the 'collision', in the simplest case you can just forward notifications to the parent.

Thx CE. Im not sure if I understand but I just set DragContainer::setDragDropTarget to false on all the dragable items (DragContainer) and now the drops go to the parent..
