This library adds a new type of scrollview widget to the widget.* library under the name widget.newDragItemsScrollView(). The scroll view can then have display objects added to it which can be dragged off the scrollview by either touching and holding or pulling them in a given direction.
DMC Corona UI is an advanced widget library for Corona and contains Widgets, Styles and Controls.
Many of the Widgets wrap other OpenGL or platform-native objects to make them behave more consistently. All of the components are style/theme-aware.
