OSF Prog Guide 5.1 states "a single-reply Dialog widget is modal in nature.
This means that a reply is required before the application can continue."
My goal: in a program where there are multiple application shells created
by XtAppCreateShell, I want to pop up a dialog in one of these which
demands user response (locking out other buttons until the modal dialog
is satisfied) without affecting the other App Shells.
So I try to create such a widget:
XtSetArg (args[n], XmNdialogStyle, XmDIALOG_APPLICATION_MODAL); n++;
modal = XmCreateMessageDialog (parent, "ShouldBeModal", args, n);
Let there be some button whose callback is
void modalup (w, d, call_data)
{ XtManageChild(d); }
Now when that button is pressed,the message dialog pops up nice as can be,
BUT it is NOT modal: every other button in its App Shell (and the other
App Shells as well) continue to perform just as when the "modal" dialog
is absent.
Please help me understand how to make "ShouldBeModal" behave. I am unsure
how to find whether the proper widget got the intended resource value
binding. I'll be grateful for help.

I've just tried this and it seems to do the trick - ie halts the application until the message box is responded to.
