I would like to run two monitors off of the same PC, each of which
displaying different information.
With a setup like this, is it possible for a single application to write
to both displays, or is it
necessary to run different apps on each?
Qestion 2:
I have a dialog box which I populate with controls dynamically.
Specifically I place about 20 buttons on a pane. For each button
I have been able to attach a callback, but I also want to open another
dialog box on each of these buttons activate event. How do you do this
in code? An short example would be appreciated. I have temporarily
solved the problem by opening the dialog box and unrealizing it until
the
button is pressed - then the callback realizes it.

Yes you can do this only you are going to be interested in location
you´re doing your drawing. For info on setting up your dual monitor
system take a look at the following knowledge base entry. http://qdn.qnx.com/support/bok/solution.qnx?9490

I think what you’re looking for here is the PtAddCallbacks(). This lets
you add as many callbacks as you want to your widget.
For example:
{
PtWidget_t *button;
int push_button_cb( PtWidget_t *, void *,
PtCallbackInfo_t *);
PtCallback_t callbacks[] = { {push_button_cb, NULL} };
