Re: Initilize a filter

GTK Wizard using Notebook
Hi, I'm new to programing, especially gtk. I'm wanting to create a gtk wizard (without a dependency on Gnome - I'm aware of the druid). I thought the best way might be to create a notebook and have forward and back buttons cycle through the tabs. My question iscan someone give me some pointers on how to best cycle through the tabs??

Re: GThread and GCond

Hi,
I hope you can help me ;)
I'm working with two threads. One of them is running in an infinite loop
(well, it finishes under certain conditions)
What I want to do is that the infinite loop pauses some times. So I create a
GCond, but I think I didn't understand how it works.
I do something like this:
Thread 1:
for (;;){
g_mutex_lock(my_mutex);
g_cond_wait(my_cond,mi_mutex);
do_some_work_here
g_mutex_unlock(mi_mutex);
}
The Thread 2 asynchronously toggles the value of a variable between 0 and 1.
When the value is 1, I want the loop runs continuously, but when it is 0,
the loop stops.
if (value==0){
value=1;
g_cond_signal(my_cond);
}
else
value=0;
I've read this:
http://developer.gnome.org/doc/API/2.0/glib/glib-Threads.html#g-thread-create
The
GCondhttp://developer.gnome.org/doc/API/2.0/glib/glib-Threads.html#GCondstruct
is an opaque data structure to represent a condition
So, the GCond represents the condition, and are not the condition itself...
So when I use g_cond_signal I think I'm telling the condition is true,
unlock. But in the next iteration, the loop locks again.
How can I tell The condition is STILL true...?
The condition is just a thing you can wait on untill its signalled,
thats all... there is no relation between your 'value' variable
and the condition.
in this small example; the musicplayer frontend pauses the worker
thread (that usually loops in a read/write loop):
Player worker thread:
/* This code is at the beginning of the loop (before writing
* the next chunk of song data
*/
mp_mutex_lock(mp-paused_mutex);
while (mp-paused) {
g_cond_wait(mp-paused_cond, mp-paused_mutex);
}
mp_mutex_unlock(mp-paused_mutex);
Musicplayer frontend thread:
===
To pause the player thread:
mp-paused = TRUE;
To unpause the player thread:
mp-paused = FALSE;
g_cond_signal (mp-paused_cond);
Cheers,
-Tristan
