Positioning Relative to the Form Limits

You can place a new gadget relative to the limits of the form so far.

For example, to place CANCEL and OK gadgets at the base of a form:

button .CANCEL at xmin form ymax form+0.5 CANCEL

This extends the form by adding a CANCEL button at bottom left.

path right

button .OK at xmax form - size OK

This adds an OK button, aligned to the right hand side of the form (without increasing its width).

Note:
The omission of the Y co-ordinate, which is auto-placed at ymin of the previous gadget.
