Thank you all for your help.
I tried adding stderr to my printf function but it still seems to be
buffered. Here is the code that I am working with:
#include <gtk/gtk.h>
#include <stdio.h>
void on_combobox1_changed (GtkComboBox *widget, gpointer user_data) {
printf("on_combobox1_changed event");
// int hello = GPOINTER_TO_INT(user_data);
// printf("%d", hello);
// GtkWidget window = GTK_WIDGET( widget );
GdkColor color;
// gdk_color_parse(gtk_combo_box_get_active_text(widget), &color);
gdk_color_parse("blue", &color);
gtk_widget_modify_bg (GTK_WIDGET (widget), GTK_STATE_NORMAL, &color);
}
void
on_window_destroy (GtkObject *object, gpointer user_data)
{
printf("on_window_destroy event");
gtk_main_quit ();
}
int
main (int argc, char *argv[])
{
// GtkWidget *combobox1;
GtkBuilder *builder;
GtkWidget *window;
GdkColor red;
gtk_init (&argc, &argv);
builder = gtk_builder_new ();
gtk_builder_add_from_file (builder, "testcolor1.xml", NULL);
window = GTK_WIDGET (gtk_builder_get_object (builder, "window"));
gdk_color_parse ("red", &red);
gtk_widget_modify_bg (window, GTK_STATE_NORMAL, &red);
gtk_builder_connect_signals (builder, NULL);
// GtkComboBox *combobox1 = GTK_COMBO_BOX (builder);
// g_signal_connect(G_OBJECT(combobox1), "clicked", G_CALLBACK
(on_combobox1_changed), NULL);
g_object_unref (G_OBJECT (builder));
gtk_widget_show (window);
// gtk_widget_modify_bg (window, GTK_STATE_NORMAL, red);
gtk_main ();
return 0;
}
