<interface name="qt_toplevel_drag_manager_v1" version="1">
<description summary="Move a window during a drag">
This protocol enhances normal drag and drop with the ability to move a
window at the same time. This allows having detachable windows that
can also be reattached when dragged back to another window or some special
zone.
Warning! The protocol described in this file is currently in the testing
phase. Backward compatible changes may be added together with the
corresponding interface version bump. Backward incompatible changes can
only be done by creating a new major version of the extension.

<request name="get_qt_toplevel_drag">
<description summary="get an qt_toplevel_drag for a wl_data_source">
Create an qt_toplevel_drag for a drag and drop operation that is going
to be started with data_source.
This request can only be made on sources used in drag-and-drop, so it
must be performed before wl_data_device.start_drag. Attempting to use
the source other than for drag-and-drop will raise an invalid_source error.

Request that the window will be moved with the cursor during the drag operation. The offset
describes how the toplevel will be positioned relative to the cursor hotspot

Issuing this request after the drag has ended will result in a drag_ended protocol error.
