resize grid by dragging edges

Do you have any examples of resizing the grid in real time by clicking and dragging the borders of the grid to resize?

Thanks

Grid doesn't support such functionality. Something similar will be available in oncoming version, where grid can be linked to window or layout element and resized with it, but not in current version. 
Technically you can use any kind of resizable container and just call grid.setSizes()  to adjust grid to the new size of container.
