|
|
* This handy class is a simple way to drop something on another
|
|
* view. It handles drop events, always setting itself to the size of
|
|
* its parent.
|
|
*
|
|
* Altered to support a callback so it can return the item
|
|
* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
* Pulled into its own file for more widespread use
|
|
* Rewritten by Liru Færs to act as its own ui element and use a control
