GTK 制作学习笔记（一）

通过这几天GTK的学习，网上关于gtk的资料少之又少！

分享几个执行成功的案例，纯用来感兴趣的学习使用。

下面是制作一个接盘界面，可以模拟鼠标点击，点击Quit可以退出。

一、效果图：

二、代码：

这个代码对gtk版本没有太大要求，2.-或者3.-或者4.-应该都可以，大家可以尝试后留言，我这个是gtk2版本。

#include <gtk/gtk.h>
/* 我们的回调。
* 传到这个函数的数据被打印到标准输出 */
void callback(GtkWidget* widget, gpointer data)
{
    g_print("%s", (char*)data);
}
/* 这个回调退出程序 */
gint delete_event(GtkWidget* widget, GdkEvent* event, gpointer data)
{
    gtk_main_quit();
    return FALSE;

    /* 为 delete_event 设置一个立即退出 GTK 的处理函数。 */
    g_signal_connect(G_OBJECT(window), "delete_event", G_CALLBACK(delete_event), NULL);
