It sounds like you are talking about two different things there. A
dialog box, by definition, would be some sort of warning or information
provided by a program through the use of a seperate window. A modal
dialog box would be a dialog box that requires the user to respond,
which it acomplishes by ignoring all events outside of the dialog box
window.
But you were also discussing starting a new process via fork(). I am
confused as to which concept you are interested in, but I will take a
stab at the dialog box.
It would be really easy to implement a modal dialog box within a
program. Simply create a new window, populate it, and then force it to
the top with GrRaiseWindow(). Next, you can implement a small event
loop to filter all events coming in until the dialog box is responded
to. For example:
void dialog_box()
{
win = create_dialog_box();
show_dialog_box(win);
while(1)
{
GR_EVENT event;
GrGetNextEvent(event);
if (event.general.wid != win) continue;
... Handle expose and other events here ...
if (event.type == GR_EVENT_BUTTON_DOWN)
break;
}
close_dialog_box(win);
}
Note that this will be effective only for the client in question, not
for other clients or the window manager. Unlike Windows, we have no way
of implementing a system wide modal box (and I hope we never do!!!)
