glade3教程（六）--微调按扭跟组合框

   文字描述不出来  所以直接上图：

将文件保存为spin.glade  在code::blocks里面输入以下代码：

#include <gtk/gtk.h>
GtkWidget *label1;
GtkWidget *label2;
GtkWidget *spin;
GtkWidget *combobox;
void set_label1(GtkWidget *widget,gpointer data)
{
    gint text;
    const char buf[6];
    text=gtk_spin_button_get_value_as_int((GTK_SPIN_BUTTON(spin)));
    sprintf(buf,"%d",text);
    gtk_label_set_text(GTK_LABEL(label1),buf);
}
void set_label2(GtkWidget *widget,gpointer *data)
{
    const char *text;
    text=gtk_combo_box_get_active_text(GTK_COMBO_BOX(combobox));
    gtk_label_set_text(GTK_LABEL(label2),text);
}
int main(int argc, char *argv[])
{
    GtkBuilder *builder;
    gtk_init(&argc, &argv);
    GtkWidget *window;
    GtkWidget *button1;
    GtkWidget *button2;

    builder = gtk_builder_new();
    gtk_builder_add_from_file(builder, "spin.glade", NULL);
    window = GTK_WIDGET(gtk_builder_get_object(builder, "window"));
    spin = GTK_WIDGET(gtk_builder_get_object(builder,"spinbutton"));
    combobox = GTK_WIDGET(gtk_builder_get_object(builder,"combobox"));
    button1 = GTK_WIDGET(gtk_builder_get_object(builder,"button1"));
    button2 = GTK_WIDGET(gtk_builder_get_object(builder,"button2"));
    label1 = GTK_WIDGET(gtk_builder_get_object(builder,"label1"));
    label2 = GTK_WIDGET(gtk_builder_get_object(builder,"label2"));
    gtk_combo_box_set_active(GTK_COMBO_BOX(combobox), 0);
    g_signal_connect(G_OBJECT(window),"delete_event",G_CALLBACK(gtk_main_quit),NULL);
    g_signal_connect(G_OBJECT(button1),"pressed",G_CALLBACK(set_label1),NULL);
    g_signal_connect(G_OBJECT(button2),"pressed",G_CALLBACK(set_label2),NULL);

   // gtk_builder_connect_signals(builder, NULL);//自动关联已在 UI 文件配置好的信号  如果你不在galde文件里面配置信号这行代码可以不用

    g_object_unref(G_OBJECT(builder));
    gtk_widget_show_all(window);
    gtk_main();
    return 0;
}

运行如图所示：
