  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

  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);
