原本由于项目需求在 Linux 下学习过一段时间的 GTK+2.0 图形开发，时隔一段时间，想真正深入学习一下 GTK 。
这次直接从头学习 GTK+-3.0 ，并写下博文便于日后查看，也方便新手入门。
安装环境参考：
Arch ：直接执行 sudo pacman -S gtk3 即可。
注意采用的是GTK3，上文中大部分是GTK2，注意同样的方式安装GTK3。
首先学习到的便是创建一个空白的窗口。我们创建一个名为 example.c 的源文件。内容如下
#include //每个GTK程序都要包含的头文件，里面申明了很多类型，函数原型等
static void activate (GtkApplication *app , gpointer data)
{
GtkWidget *window; //申明一个窗口
window = gtk_application_window_new(app); //为app创建一个窗口
gtk_window_set_title(GTK_WINDOW(window) , "Application"); //设置窗口的标题
gtk_window_set_default_size(GTK_WINDOW(window) , , ); //设置窗口默认大小为长宽各200像素
gtk_widget_show_all(window); //显示窗口
}
int main(int argc , char **argv) //主函数
{
GtkApplication *app; //申明创建一个 GtkApplicatin对象名为app
int app_status; //用于拿到app 运行结束后的返回值
app = gtk_application_new("org.rain.gtk" , G_APPLICATION_FLAGS_NONE); //创建一个application
g_signal_connect(app , "activate" , G_CALLBACK(activate) , NULL); //连接信号，初始化app时，调用 activate 函数
app_status = g_application_run(G_APPLICATION(app) , argc , argv); //运行app
g_object_unref(app); //销毁app
return app_status;
}
如下方式编译源文件，并执行生成的example可执行文件。
gcc example.c `pkg-config --cflags --libs gtk+-3.0` -Wall -o example
./example
运行结果如下：
