I may be wrong about this, but I think you want to write this function
like:
gint on_butt_close_clicked(GtkButton *button, gpointer user_data)
{
gtk_widget_hide((GtkWidget *)user_data);
return TRUE;
}
Returning TRUE will prevent the window from being destroyed..
Hope this helps..

Hello friends,
I want to hide a window when user clicks either on the
close button or press the close (CROSS) on the
top-right of every window.
Here is my code:
GtkWidget *window1;
GtkWidget *butt_close;
g_signal_connect((gpointer)butt_close,clicked,
G_CALLBACK (on_butt_close_clicked), (gpointer)
window1);
g_signal_connect ((gpointer) window1, destroy,
G_CALLBACK (on_butt_close_clicked), (gpointer)
window1);
void on_butt_close_clicked(GtkButton *button,gpointer
user_data)
{
gtk_widget_hide((GtkWidget *)user_data);
}
The window hides up when I click the close button but
when I try and hide it through clicking the close
button on the top right of the window it gives the
following error:
[snip]
You cannot call gtk_widget_hide() on a widget when it is destroyed (its
GdkWindow has gone). You probably meant to connect to the delete-event
signal. That is what is emitted when you click the top right button you
refer to.

Xlib: unexpected async reply
Hi list!
I get this error when runing my GTK application:
Xlib: unexpected async reply (sequence 0xdfd)!
(Te sequence number varies.)
A little explanation about the application:
It runs two threads. One of them is runing inside the gtk_main() loop.
The other one, periodically reads from different files and updates the
labels in the window. I use gdk_threads_enter() and gdk_threads_leave() to
block the other thread.
The aplication has a Tabbed Pane. Each tab shows information from a
different file.
Now, I get this error when I try to see the information showed by the last
tab I added. Basically, the cycle I implement is (pseudocode):
infinite_loop{
...
if tab1_is_visible{
update_tab
}
...
pause;
}
and update_tab performs:
read_value_from_file();
gdk_threads_enter();
update_labels();
gdk_threads_leave();
Since the error is realted to Xlib, I think I'm doing something wrong about
multi-threading, but I can't find what.
I'm doing as I did with the other tabs and I hadn't any errors like this
I've read http://mail.gnome.org/archives/gtk-list/1999-July/msg00438.htmlbut
I think this does not match my problem. I'm not calling to gtk
functions
from callbacks or signal handlers.
Any suggestions?
Best regards!

Xlib: unexpected async reply
Hi, it's me again... now a bit embarrassed I found the problem after more and more debugging. The read_data_from_file() function was a function with variable number of parameters implemented with va_list... Due to a stupid mistake this function did not return when a certain number of parameters was passed and then the function run into an infinite loop. So I suppose that the message queue of Xlib was overflowed in some way. Well, I hope this is helpful for someone with a similar problem :) Best regards! ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
Re: selected text is PRIMARY?
Xavier Bestel wrote: It does not cause any problem. Just some people want to switch from a well-defined behavior (one PRIMARY per DISPLAY) Noone wants to change *this*. to a fuzzy one: you want to have several selections, but how many ? - One selection per application ? - One selection per window ? - One selection per widget ? One selection per whatever thing user can select text in. Just think about select text using mouse and it becomes pretty simple. I believe it means one selection per widget in practice, though there may be crazy widgets which can have multiple selections as well (maybe some canvas with fancy stuff inside). (Note that you can have more than one application per window). You do not select text in applications, you select it in windows, controls, widgets, boxes, etc. I smell the mess, inconsistent between toolkits and applications. We already have inconsistency between toolkits and applications, it's not a reason to continue to limit useful functionality. Keep to well-defined and simple behavior, guys. What exactly in multiple selections business is complicated or not well-defined? The question how many above is not an answer: it's the same question as whether given widget should be able to have selection at all.

modifying the colormad does not modify the pixmap.
