First, thanks to all who responded to my request concerning closing a
window without confirming. Now I have a another question...
I open a window (window #1) under SunView using window_create(), and then
a subsequent call to window_main_loop(). If I detect certain events in
the window, I want another window to open (window #2), and receive events
in the new window. When a certain event occurs in window #2, I close the
window, and want to start getting events in window #1 once again.
Here's what I want to do:
create_window() creates window #1
window_main_loop() for window #1
later on...
create_window() creates window #2
window_main_loop() for window #2
later on...
window_done() for window #2
At this point, I want to start getting events for window
#1 again.
When I try this, I run into problems:
1. When I call window_main_loop() for window #2, I
get:
Notifier error: Invalid argument
2. When I quit out of window #2, I get a stream of:
.
.
.
WIN ioctl number 2000671E: Bad file number
WIN ioctl number C00C671D: Bad file number
WIN ioctl number C014671F: Bad file number
WIN ioctl number C0146720: Bad file number
WIN ioctl number 2000671E: Bad file number
.
.
.
3. After quitting out of window #2, window #1
is dead in the water. It gets no events.
I must be hosing the notifier by calling window_main_loop()
a second time before the first call to window_main_loop()
returns.
I realize that I could use a SunView popup to do what I
want, but, for reasons I won't go into, I need it to be just
a regular old window.
BTW I have RTFM, but I've gotten nowhere ;-(
Any suggestions?
