I have a dialog in the centre of the screen. Some user action causes a second dialog to open. It opens over the first dialog.
The user has to move the second dialog in order to see the first. 
I'd like to be able to have the second dialog surface offset by some stated amount from the first.
I could do this with ~moveTo() or maybe ~moveWindow(). But in both cases I'd need to check where on the screen the first dialog is so that the second is not half-off or wholly off the screen. To do this would take a bit of work: check screen size, check dialog1 position, then work out where to bring up the second window - above, below, left, right, or some combination such as "to the upper left".
Is there a simple way to surface a dialog so that it's offset by some defined amount, but where ooDialog or Windows provides a default new position - i.e. to the right, left, top, or bottom of the first dialog?
Many thanks
