GTK+实例学习（笔记）

第1个例子：建立窗体

程序代码：
#include<gtk/gtk.h>

int main(int argc,char *argv[])
{

 GtkWidget *window;//定义

 gtk_init(&argc,&argv);//初始化

 window=gtk_window_new(GTK_WINDOW_TOPLEVEL);//创建窗口

 gtk_widget_show(window);//显示窗口

 gtk_main();

 return 0;
}

/*

 * GNOME既是一个桌面，也是一个完整的程序设计环境

 * GIMP是UNIX操作系统上的影像处理程序

 * GTK+是GIMP工具包，能支持许多程序设计语言

 * GTK+使用GLIB库和GDK库

 * GLIB定义了数据类型，提供了错误处理和内存管理方面的函数

 * GDK是本地图形化API和GTK+中间的一个过渡层，需要依赖具体的计算机平台，移植GTK+重新编写GDK

 * GTK+的安装就不多述，命令pkg-config --modversion gkt+-2.0检验GTK+2.0

 * 命令gcc 000.c -o 000 `pkg-config --cflags --libs gtk+-2.0`编译程序

 * 执行000即可查看结果，命令./000

 * 如果在命令行中打开，在关闭时并没有退出，要通过CTRL+C来关闭

控制台输出信息
第2个例子：控制台输出信息
程序代码：
#include<gtk/gtk.h>

int main(int argc,char *argv[])
{

 GtkWidget *window;

 gtk_init(&argc,&argv);

 window=gtk_window_new(GTK_WINDOW_TOPLEVEL);

 gtk_widget_show(window);

 g_print("hello world");//在控制台打印信息，通常测试用

 g_warning("hello world");//在控制台输出警告信息

 g_message("hello world");//输出信息

 gtk_main();

 return 0;
}

每隔5秒在控制台打印信息
程序代码：
#include<gtk/gtk.h>

gint n=1;//glib数据类型同C语言基本类型，只是在前面加一个g
gint function(gpointer data);

int main(int argc,char *argv[])
{

 GtkWidget *window;

 gpointer data;

 gint sign;

 gtk_init(&argc,&argv);

 window=gtk_window_new(GTK_WINDOW_TOPLEVEL);

 gtk_widget_show(window);

 sign=g_timeout_add(500,function,data);//每隔5秒打印信息

 gtk_main();

 return 0;
}

gint function(gpointer data)
{

 g_print("hello\n");

 

 if(++n>5)
  return 0;
}

关闭窗体时也从控制台退出
程序代码：
#include<gtk/gtk.h>

int main(int argc,char *argv[])
{

 GtkWidget *window;

 gtk_init(&argc,&argv);

 window=gtk_window_new(GTK_WINDOW_TOPLEVEL);

 g_signal_connect(GTK_OBJECT(window),"destroy",G_CALLBACK(gtk_main_quit),NULL);

 //关闭时自动退出

 gtk_widget_show(window);

 gtk_main();

 return 0;
}

窗体属性

 gtk_main_quit();
}

{

 GtkWidget *window;

 gtk_init(&argc,&argv);

 window=gtk_window_new(GTK_WINDOW_TOPLEVEL);

 g_signal_connect(GTK_OBJECT(window),"destroy",G_CALLBACK(destroy),NULL);//关闭窗口时调用函数

 gtk_window_set_title(GTK_WINDOW(window),"Main Window"); //设置窗体标题

 gtk_window_set_resizable(GTK_WINDOW(window),FALSE); //设置窗体是否可改变大小

 gtk_widget_set_size_request(window,200,200); //设置窗体初始大小

 gtk_container_add(GTK_CONTAINER(window),button);

 gtk_container_set_border_width(GTK_CONTAINER(window),20);//窗口边框宽度

 gtk_widget_set_sensitive(button,FALSE); //按钮是否敏感，FALSE表示不敏感，则无法单击心以及调用函数
