Here's a short demo of some of the stuff that ObjectHandles (my Flex library for moving & resizing stuff) can do with a very minimal amount of code.
The custom things I did:
- Has a MOVING / RESIZING event handler to show a custom tooltip (hides the tooltip on MOVED / RESIZED)
- Has custom resize handle images that look like grey horizontal bars
- Only allows vertical resizing (allowHResize = false).
- On a MOVED event, the objects have an animation that snaps them to a column.
It's a little hard to see in that video, but the duration & start time in the tooltip update as you move or resize the boxes around.
