Hi!
I have some trouble using eventbox'es.
I create a eventbox and I connect a signal to it...
>gtk_signal_connect (GTK_OBJECT(event_box), "button_press_event",
> GTK_SIGNAL_FUNC (gw), GINT_TO_POINTER(var));
but when in the gw() function print the var it is wrong...
> g_print("got: %d \n", GPOINTER_TO_INT(data));
(see eventbox.c that I've attached)
Anyone have any clue what I've done wrong?
//Mvh Niklas
#include <gtk/gtk.h>
void gw(GtkWidget *widget, gpointer data)
{
g_print("got: %d \n", GPOINTER_TO_INT(data));
}
int main( int argc,
char *argv[] )
{
GtkWidget *window;
GtkWidget *event_box;
GtkWidget *label;
gint var = 123;
gtk_init (&argc, &argv);
window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
gtk_window_set_title (GTK_WINDOW (window), "Event Box");
gtk_signal_connect (GTK_OBJECT (window), "destroy",
GTK_SIGNAL_FUNC (gtk_exit), NULL);
gtk_container_set_border_width (GTK_CONTAINER (window), 10);
/* Create an EventBox and add it to our toplevel window */
event_box = gtk_event_box_new ();
gtk_container_add (GTK_CONTAINER(window), event_box);
gtk_widget_show (event_box);
/* Create a long label */
label = gtk_label_new ("CLICK ME");
gtk_container_add (GTK_CONTAINER (event_box), label);
gtk_widget_show (label);
/* Clip it short. */
gtk_widget_set_usize (label, 110, 20);
/* And bind an action to it */
gtk_widget_set_events (event_box, GDK_BUTTON_PRESS_MASK);
gtk_signal_connect (GTK_OBJECT(event_box), "button_press_event",
GTK_SIGNAL_FUNC (gw), GINT_TO_POINTER(var));
/* Yet one more thing you need an X window for ... */
gtk_widget_realize (event_box);
gdk_window_set_cursor (event_box->window, gdk_cursor_new (GDK_HAND1));
gtk_widget_show (window);
gtk_main ();
return(0);
}
