我们在这篇文章中将会为大家介绍

PHP GTK写文本查看器代码示例:

  1. ?php
  2. require_once('File.php');
  3. if (!class_exists('gtk')) {
  4. if (strtoupper(substr(PHP_OS, 0,3) == 'WIN'))
  5. dl('php_gtk.dll');
  6. else
  7. dl('php_gtk.so');
  8. 10 }
  9. function delete_event()
  10. {
  11. return false;
  12. }
  13. function shutdown()
  14. {
  15. print("Shutting down");
  16. gtk::main_quit();
  17. }
  18. function ButtonLoad_clicked()
  19. {
  20. SelectFile();
  21. }
  22. function ButtonClose_clicked()
  23. {
  24. global $window;
  25. $window->close();
  26. }
  27. function fs_OK($button, $fs)
  28. {
  29. global $TextBox;
  30. $TextBox->insert_text
    (File::readAll($fs-
    >get_filename()), 0);
  31. return true;
  32. }
  33. function fs_Cancel()
  34. {
  35. return false;
  36. }
  37. function SelectFile()
  38. {
  39. $fs = &new GtkFileSelection
    ('Please select the file');
  40. $ok_button = $fs->ok_button;
  41. $ok_button->connect('clicked', 'fs_OK', $fs);
  42. $ok_button->connect_object
    ('clicked', array($fs, 'destroy'));
  43. $cancel_button = $fs->cancel_button;
  44. $cancel_button->connect
    ('clicked', 'fs_Cancel');
  45. $cancel_button->connect_object
    ('clicked', array($fs, 'destroy'));
  46. $fs->show();
  47. }
  48. $window = &new GtkWindow();
  49. $window->connect(
    'destroy', 'shutdown');
  50. $window->connect('delete-event'
    , 'delete_event');
  51. $window->set_border_width(0);
  52. $TextBox = &new GtkText();
  53. $TextBox->set_editable(true);
  54. $ButtonLoad = &new GtkButton('Load');
  55. $ButtonLoad->connect('clicked',
    'ButtonLoad_clicked');
  56. $ButtonClose = &new GtkButton('Close');
  57. $ButtonClose->connect('clicked',
    'ButtonClose_clicked');
  58. $VBox = &new GtkVBox(false, 10);
  59. $VBox->pack_start($ButtonLoad);
  60. $VBox->pack_start($ButtonClose);
  61. $HBox = &new GtkHBox(false, 10);
  62. $HBox->pack_start($TextBox);
  63. $HBox->pack_start($VBox);
  64. $window->add($HBox);
  65. $window->show_all();
  66. gtk::main();
  67. ?>
