打开glade3 新建一个窗口,在窗口中放置一个固定fixed然后再放置三个检查按钮 三个单选按钮 放置一个双态按钮 然后分别在检查按钮 单选按钮 双态按钮下面分别放置一个标签 并且将单选按钮2 单选按钮3 加入单选按钮1的组别中 保存为button.glade 如图所示:

然后打开code::blocks 输入以下代码 代码比较简单就不加注释了

g_signal_connect(G_OBJECT(togglebutton),"toggled",G_CALLBACK(set_text_to_label3),"toggle");
// 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;
}
编译运行 点击不同按钮 会输出不同的文字
如图:

以上对于按钮的回调仅用来演示 实际运用当中 应如用以下代码判断
if (GTK_TOGGLE_BUTTON (widget)->active)
{
/* 如果执行这段程序,表明按钮是选中或者按下的* /
} else {
/* 如果执行这段程序,按钮是没有选中或者弹起的* /
}
