RE:Multithreading and dialog boxes

["Rokicki, Andrew" <ARokicki US TIAuto com>]

	I am kind of new to GTK. I am in the process of porting our
application that was written with ncures and pthreads to GTK.
	Well I am in evaluation stage, but Try this:
	void dialog (void)
	 {	
		 GtkWidget *dialog;	
	    gdk_threads_enter();
		dialog = gtk_message_dialog_new(NULL,
GTK_DIALOG_DESTROY_WITH_PARENT,
						GTK_MESSAGE_WARNING,
GTK_BUTTONS_OK, "Sample message");
		 g_signal_connect_swapped (GTK_OBJECT (dialog), 
	                             "response", 
	                             G_CALLBACK (gtk_widget_destroy),
	                             GTK_OBJECT (dialog));
	   /* Add the label, and show everything we've added to the dialog.
*/
	    gtk_widget_show_all (dialog);
		gdk_threads_leave();
		}
	ALSO:
	in make file have something like this:
	$(TARGET) : $(TARGET).o 
	        $(CC) -o $(TARGET) $(TARGET).o `pkg-config --libs
gthread-2.0` `pkg-config --libs gtk+-2.0` -lgtk-x11-2.0 -lpthread  
	$(TARGET).o : $(TARGET).c 
	        $(CC) -D_REENTRANT -c `pkg-config --cflags gthread-2.0`
`pkg-config --cflags gtk+-2.0` $(TARGET).c

Hi,

(Gtk2) Whenever I run a dialog box from inside a thread, the dialog box
never gets destroyed, and it hangs my application:

void dialog (void) {
	GtkWidget *dialog;

	gdk_threads_enter();

	dialog = gtk_message_dialog_new(NULL,
					GTK_DIALOG_DESTROY_WITH_PARENT,
					GTK_MESSAGE_WARNING,
					GTK_BUTTONS_OK,
					"Sample message");

	gtk_dialog_run(GTK_DIALOG(dialog));
	gtk_widget_destroy(dialog);

	gdk_threads_leave();
}

It works fine when called within the main thread, btw.

Any clue?

Regards,
Jean-Yves Lefort
