I was just reading the information about the PtIsFocused() call in the
QNX4 helpviewer and I had a question about something that I read. In
the section on the return codes, it talks about concepts of “The widget
is on the focus branch” and “The widget is the focus leaf”. What
exactly are the focus branch and focus leaf, and if I was to say use
this function with a PtNumericFloat widget, which of these two cases
would imply that the widget had focus?
Thanks very much.
