It seems like this would do what you want:

1) Make sure the group is pre-populated with a hidden version of every 
control type.  One circle, one line, one checkbox, etc. (whatever 
controls you want).

2) On mouseDown, have a group handler which positions and sizes the 
hidden control to the mouse location, and then sets it visible.

3) Resize and position the control in real-time in a mouseMove handler.

4) On mouseUp, copy the control, and then re-hide the original.

Wouldn't that do what you want?
