my reason for needing this is to build a control similar to outlooks calendar thingy where you can drag and expand an event time span on a calendar thing. From another suggestion, I'm using canvas now with a box. The blow code, warning the colours are absolutely horrible, it is just an example afterall, works when I drag left/right from the within the white area of the box. It also works the way I want when I drag the right side of the box, the black bar on the right. but I can't quite get teh left black bar drag to work. I want it so when the left black bar is dragged left the box expands in width to the left. So, I have changing the widhth and moving the x coord of the box at the same time to simulate 'strethcing' on the left side. Seems these two ops cancel each other out. any ideas?
