Hi,
I'm trying to execute an external program and have a
popup which signals the user to wait for the program to
end. In my callback which executes the program I have
something like:
jb_msg_create("wait blabla"); /* this creates the popup window */
/* now try to wait until the window has been created and displayed */
n = gtk_events_pending();
for (i=0; i<n; i++) {
gtk_main_iteration();
}
exec_program();
jb_show_results();
return;
But this doesn't give me the desired result as it does not handle
all pending events, so I must be doing something wrong.
I then tried:
n = gtk_events_pending();
while (n > 0) {
for (i=0; i<n;i++) {
gtk_main_iteration();
}
n = gtk_events_pending();
}
But this is blocking in gtk_main_iteration() and will only continue
after I move the mouse.
So what is the recommended way of handling such a scenario?
Regards,
Marc.
