Hello everybody, I'm using Thumbs to resize a Control.
To get this I have an Adorner that consists of some Thumbs at the corners of the AdornedElement (the Control).
Each thumb handles the DragDelta event and I resize the AdornedElement accordingly.
As the size is changed (a little mouse drag delta, in fact), the Thumbs at each corner should be redrawn at their new positions. I force this "redraw" by calling AdornedElement.InvalidateArrange().
Then, the Thumbs are redrawn OK.
The problem is that while dragging I can observe a VERY ANNOYING jitter, making the whole Control vibrate like crazy while the drag operation is made.
The deltas vary abruptly like if they are getting a wrong delta.
Please, help me, I don't know how to make the dragging smooth!!
