Vector drawing component for Delphi?

As part of developing a quotation system for our product, we would like to generate a simple line drawing of the item the user is interested in. This would mostly be a simple shape (square, rectangle, semi-circle) of arbitrary dimensions, with different border widths, border colors, and fill pattern.

In addition, we would like to generate several shapes, and have the user move them around on the screen-- not edit or change the shape, just move several shapes in relation to each other.

Is anyone aware of a component or add-on that would allow on-the-fly generation of (relatively) simple shapes/line-drawings within a Delphi app?

Any ideas? Comments? Suggestion? Thanks in advance.

Look under the 'Additional' tab of the component toolbar.  There is a component called TShape there.  These can be squares, ellipses and so on.  Once you drop the component on the canvase you can move it around.  You can also create instances of it on the fly.

I am aware of the design-time shape components. However, we need to generate a shape (typically a frame consisting of several overlapping rectangles) and allow the user to move it around in relation to other shapes he has already defined.

(i.e. ok, our product is windows. The user chooses a window size, and grille type, and we generate a simple line drawing (but to scale) of the window, including grille pattern. To create a combination window, you define several single windows, and drag them together to create the one combination unit)

Is there a way to create the shapes, and still allow the user to drag them around at run-time?

Yes, while I haven't had time to actually do it...you should be able to create an instance of the TShape on the form and hook it to some generic pick and drag code.

It actually sounds like fun.  I'll try it myself and let you know.  

If you want to get started yourself you would do something like:

aSquare := TShape.create( aOwner)
{ set the various attributes progammatically }
{ set the parent to the form ... so that the object shows up }
{ set some event handlers to methods you've written to handle mouse clicks and so on.}
