Gtk execution question
How do I make a sort of wait which test a variable value,
for continuing normal gtk execution ?
For example :
-
void HANDLER_file_select_button_ok( GtkWidget *w,
GtkFileSelection *fs )
{
my_test_variable= 0;
}
/* create a file selection dialog */
wfs= gtk_file_selection_new(Open existing file);
/* connect handler HANDLER_select_file_button_ok to the
OK button of the file selection dialog*/
g_signal_connect( G_OBJECT( GTK_FILE_SELECTION(wfs)-ok_button ),
clicked,
G_CALLBACK( HANDLER_file_select_button_ok), wfs );
/* show the file selection dialog */
gtk_widget_show(wfs);
/***/
/* HERE I would like to stop gtk execution while the OK button */
/* of the file selection dialog is not pressed,*/
/* but GTK execution go on and makes the */
/* following 'window widget' :( */
/***/
/* follow code which make and show another widget */
window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
gtk_widget_show(window);
---
I am looking for a sort of :
...
my_test_variable= 1;
wait( my_test_variable );
...
which should wait while 'my_test_variable' change value,
(e.g. in the handler function I will change 'my_test_variable' into 0
when the ok button is pressed).
When 'my_test_variable' changes value GTK should go on and making 'window'
How can obtain this kind of behavior ?
Thank you :)

Re: Gtk execution question
Maybe I was not clear in my previous message : I connect the clicked event as shown in the code, but my problem is I don't want to show the file selection dialog and window togheter. I wish to show the window only when the ok button is pressed ! To do this a need to stop the GTK execution ! How ? But GTK shows the file selection dialog and the window without waiting OK button is pressed :( Sven Neumann [EMAIL PROTECTED] To: Lorenzo Zampese/Electrolux Professional Sent by: Sven S.P.A./Italy/Electrolux Group@Electrolux Neumann cc: [EMAIL PROTECTED] [EMAIL PROTECTED]Subject: Re: Gtk execution question rgence.de 12/11/2002 16:54 Hi, [EMAIL PROTECTED] writes: (e.g. in the handler function I will change 'my_test_variable' into 0 when the ok button is pressed).

How about putting that gtk_widget_show(window); into your callback?
Also, I assume you're calling into gtk_main() even though you didn't
show it. You never really want to stop GTK execution, since it
has to be running in gtk_main() (or a custom loop) even for your
dialog to work.

I wish to show the window only when the ok button is pressed ! To do this a need to stop the GTK execution ! you should never stop the gtk+ execution or block the main loop. If necessary you can use nested main loops but I don't think you need to do that here. But GTK shows the file selection dialog and the window without waiting OK button is pressed :( if you call gtk_widget_show() from the clicked signal handler (it's not an event!), how can it be shown earlier?

Re: Gtk execution question
My idea was the same, but I supposed there was a different way as in
Tcl/Tk scripting language (tk_wait) :)
Ok. Thank you
