hi,

i am seeking advise as to which approach is best as far as delphi is
concerned to implement the dragging of ellipses drawn on the form canvas.
That is when the mouse is clicked on a particular ellipse and then hold-down
and drag it that ellipse will be re-drawn at those new mouse positions.

do i need to have a list of ellipses that is already on the canvas.

if so how can i code the dragging, with hit-test and so forth and shall i
use arrays or tList to keep track of the ellipses.

thanks.
daniel
