PHP中怎么利用GTK实现一个文本查看器(Gtk,php,编程语言)

PHP GTK写文本查看器代码示例：

<?php

require_once('File.php');

if(!class_exists('gtk')){

if(strtoupper(substr(PHP_OS,0,3)=='WIN'))

dl('php_gtk.dll');

else

dl('php_gtk.so');

10}

functiondelete_event()

{

returnfalse;

}

functionshutdown()

{

print("Shuttingdown");

gtk::main_quit();

}

functionButtonLoad_clicked()

{

SelectFile();

}

functionButtonClose_clicked()

{

global$window;

$window->close();

}

functionfs_OK($button,$fs)

{

global$TextBox;

$TextBox->insert_text
(File::readAll($fs->get_filename()),0);

returntrue;

}

functionfs_Cancel()

{

returnfalse;

}

functionSelectFile()

{

$fs=&newGtkFileSelection
('Pleaseselectthefile');

$ok_button=$fs->ok_button;

$ok_button->connect('clicked','fs_OK',$fs);

$ok_button->connect_object
('clicked',array($fs,'destroy'));

$cancel_button=$fs->cancel_button;

$cancel_button->connect
('clicked','fs_Cancel');

$cancel_button->connect_object
('clicked',array($fs,'destroy'));

$fs->show();

}

$window=&newGtkWindow();

$window->connect(
'destroy','shutdown');

$window->connect('delete-event'
,'delete_event');

$window->set_border_width(0);

$TextBox=&newGtkText();

$TextBox->set_editable(true);

$ButtonLoad=&newGtkButton('Load');

$ButtonLoad->connect('clicked',
'ButtonLoad_clicked');

$ButtonClose=&newGtkButton('Close');

$ButtonClose->connect('clicked',
'ButtonClose_clicked');

$VBox=&newGtkVBox(false,10);

$VBox->pack_start($ButtonLoad);

$VBox->pack_start($ButtonClose);

$HBox=&newGtkHBox(false,10);

$HBox->pack_start($TextBox);

$HBox->pack_start($VBox);

$window->add($HBox);

$window->show_all();

gtk::main();

?>
