php+GTK2 学习第二篇

　　继续学习PHP+GTK，这次实际搞东西了。又学习了两天，博主在这做一下记录。

　　推荐一篇国外的文章：http://zetcode.com/gui/phpgtktutorial/introduction/

　　一定要看这篇文章！

　　一定要看这篇文章！！！

　　博主英文不好，高中开始对英语就发虚，还好浏览器自带翻译，开双页面，对照着看：），这篇文章包含了大量的例子，绝对是入门的不二选择。最快的学习方法，把里面的代码copy下来，调用，一边看效果一边看代码。

　　算了，我给你们抄过来吧! 做代码的搬运工

　　1、小例子

15      
16 
17     public function __construct() { 
18 
19         parent::__construct(); 
20          
21 
22         $this->set_title('Simple'); //标题
23         $this->set_default_size(250, 150); //大小控制
24 
25         $this->connect_simple('destroy', array('gtk', 'main_quit')); 
26 
27         $this->set_position(GTK::WIN_POS_CENTER);  //居中显示
28         $this->show(); 
29     } 
30 } 
31      
32 new Example(); 
33 Gtk::main();

　　效果如下：

效果：

　　先搬运这些例子,这只是原文章中我觉得常用一部分，原文里还有其他的例子。大家有需要可以去看看。

　　再发一遍原文章地址：http://zetcode.com/gui/phpgtktutorial/

　　附上文档的类目录：http://gtk.php.net/manual/en/html/gtkclasses.html

　　下面是自己总结的一部分:

 1 1、GtkWindow::set_position(GTK::WIN_POS_CENTER);         //window窗口居中
 2 2、GtkWindow::set_title('Simple');                       //设置窗口标题
 3 3、GtkWindow::set_default_size（250，150）;               //设置默认窗口大小
 4 4、GtkWindow::connect_simple('destroy', array('gtk', 'main_quit'));   //设置销毁关闭桌面
 5 
 6 
 7 
 8 5、 $fixed = new GtkFixed();    //定位容器
 9     $this->add($fixed);
10 
11     $button = new GtkButton("Button");              //实例化按钮（按钮名）
12     $button->set_size_request(80, 35);              //按钮大小
13     $button->set_tooltip_text("Button widget");   //按钮悬浮
14 
15     $fixed->put($button, 30, 50);        //定位位置
16 
17     $this->set_tooltip_text("Window widget");      //空白处悬浮
18 
19 6、 GtkImage::new_from_file("mincol.jpg");     //引入图片
20 
21 7、GtkWindow::modify_bg(Gtk::STATE_NORMAL, new GdkColor(6400, 6400, 6440)); // 设置背景色
22 
23 8、$vbox = new GtkVBox(false, 5); //创建一个垂直盒子容器。false,这意味着放置在垂直框中的小部件将具有相同的大小。小部件之间的垂直间距设置为5像素。
24 
25 9、$hbox = new GtkHBox（true，3）; //水平盒子容器 盒子内的所有小部件将具有相同的大小。水平部件之间将有3px的空间
26 
27 10、new GtkAlignment（1,0,0,0） //创建一个对齐容器，将其子部件放置到右侧。设置为1.0成员会把所有的空闲空间水平框的左侧
28 
29 11、$cb = new GtkCheckButton("Show title");
30     $cb->set_active(true); //单选框 默认选中
31     get_active(); //获取是否选中的状态
32 12、$entry = new GtkEntry();
33     $entry->connect('key_release_event', array($this, 'on_key_release'));
34     //文字输入框 绑定键盘操作事件
35     $sender->get_text()  获取文本框的内容
36 13、$cb = GtkComboBox::new_text(); //实例化多选框
37     $cb->connect('changed', array($this, 'on_changed')); //绑定选项改变事件
38     
39     $cb->append_text('Ubuntu');
40     $cb->append_text('Mandriva');
41     $cb->append_text('Redhat');
42     $cb->append_text('Gentoo');
43     $cb->append_text('Mint');  //添加选项框项目
44 
45     $sender->get_active_text(); //获取被选中的项目
46 
47 14、$mb = new GtkMenuBar(); //实例化菜单栏
48 
49     $filemenu = new GtkMenu();  //实例化一个菜单
50     $filemi = new GtkMenuItem("File"); //实例化项目
51     $filemi->set_submenu($filemenu); //项目关联一个菜单，加入分菜单
52     
53     $exitmi = new GtkMenuItem("Exit");
54     $exitmi->connect_simple('activate', array('gtk', 'main_quit'));  //项目绑定事件            
55     $filemenu->append($exitmi); //菜单里插入一个项目
56 
57     $mb->append($filemi); //菜单栏里添加拼装好的项目
58 
59     注意用GtkMenuItem去set_submenu GtkMenu，项目去包括菜单
60     然后用GtkMenu去append GtkMenuItem 菜单去包含项目
61     用GtkMenuBar去append GtkMenuIte 菜单栏去包含菜单

　　　　补充一、关于中文

　　　　　　中文乱码的解决方案，请把自己的php.ini里修改一行

　　　　　　php-gtk.codepage = GBK

　　　　　　并保证代码里的字符集统一

　　　　补充二、做刷新需求

　　　　　　如果要做刷新，请注意要先destory掉，然后再次走一边放进容器，并再次show。

　　　　　　尽量层级放的浅一点。

　　　　补充三、绑定函数

　　　　　　注意再给按钮绑定函数的时候，被绑定的函数默认接收的第一个参数是绑定的按钮本身，之后的参数才是绑定时的传参

1 $tmpButton->connect('clicked', array($this, 'buttonClick'), $tableName, $buttonName);
2 
3 public function buttonClick($button, $tableName, $buttonName){
4     var_dump($tableName, $buttonName);
5 }
