Hi, Here is my environment: OS: Win XP Pro IDE: Eclipse/CDT Compiler: gcc (cygwin)
I copied the code from http://www.gtk.org/tutorial/c58.html#SEC-HELLOWORLDand I got it to build the .exe but when I run it I get this: (process:28052): GLib-GObject-WARNING **: invalid cast from `(null)' to `<unknown>' 3 [main] GtkTestProj 28052 handle_exceptions: Exception: STATUS_ACCESS_VIOLATION 362 [main] GtkTestProj 28052 open_stackdumpfile: Dumping stack trace to GtkTestProj.exe.stackdump I debugged the application and found that the program exited at this line (55): g_signal_connect (G_OBJECT (window), "delete_event", G_CALLBACK (delete_event), NULL); Here is the main func: int main( int argc, char *argv[] ) { /* GtkWidget is the storage type for widgets */ GtkWidget *window; GtkWidget *button; /* This is called in all GTK applications. Arguments are parsed * from the command line and are returned to the application. */ gtk_init (&argc, &argv); /* create a new window */ window = gtk_window_new (GTK_WINDOW_TOPLEVEL); /* When the window is given the "delete_event" signal (this is given * by the window manager, usually by the "close" option, or on the * titlebar), we ask it to call the delete_event () function * as defined above. The data passed to the callback * function is NULL and is ignored in the callback function. */ g_signal_connect (G_OBJECT (window), "delete_event", G_CALLBACK (delete_event), NULL); /* Here we connect the "destroy" event to a signal handler. * This event occurs when we call gtk_widget_destroy() on the window, * or if we return FALSE in the "delete_event" callback. */ g_signal_connect (G_OBJECT (window), "destroy", G_CALLBACK (destroy), NULL); /* Sets the border width of the window. */ gtk_container_set_border_width (GTK_CONTAINER (window), 10); /* Creates a new button with the label "Hello World". */ button = gtk_button_new_with_label ("Hello World"); /* When the button receives the "clicked" signal, it will call the * function hello() passing it NULL as its argument. The hello() * function is defined above. */ g_signal_connect (G_OBJECT (button), "clicked", G_CALLBACK (hello), NULL); /* This will cause the window to be destroyed by calling * gtk_widget_destroy(window) when "clicked". Again, the destroy * signal could come from here, or the window manager. */ g_signal_connect_swapped (G_OBJECT (button), "clicked", G_CALLBACK (gtk_widget_destroy), G_OBJECT (window)); /* This packs the button into the window (a gtk container). */ gtk_container_add (GTK_CONTAINER (window), button); /* The final step is to display this newly created widget. */ gtk_widget_show (button); /* and the window */ gtk_widget_show (window); /* All GTK applications must have a gtk_main(). Control ends here * and waits for an event to occur (like a key press or * mouse event). */ gtk_main (); return 0; } Help! I want to use gtk for a cross-platform program I'm making.
