Drag & drop support on the gridwidget is a great enhancement. Current support is all fixed to one cell in the grid. With the drag&drop support data can be \\\'dragged\\\' to a target on the same row, another row or even outside the grid.
The functionality is not different than the existing functionality from a normal entity. Just the use of dragsource and droptarget.
We use several screens with drag and drop support. On all multiocc screens we implemented the grid widget, except those screens with drag&drop support on them. With the grid widget Uniface apps look very modern. Now we can not use the grid on all screens, it looks very messy.
