| 62 | </strong></dt><dd> | |
| 63 | Initialisation option. Specifies on which side of the dialog window to place the button | |
| 64 | box. Must be one of <strong>'n'</strong>, <strong>'s'</strong>, <strong>'e'</strong> or <strong>'w'</strong>. The default is <strong>'s'</strong>.</p> | |

| 79 | Specifies a function to call whenever a button in the button box | |
| 80 | is invoked or the window is deleted by the window manager. The | |
| 81 | function is called with a single argument, which is the name of | |
| 82 | the button which was invoked, or <strong>None</strong> if the window was deleted | |
| 83 | by the window manager.</p> | |
| 84 | <p> If the value of <strong>command</strong> is not callable, the default behaviour | |
| 85 | is to deactivate the window if it is active, or withdraw the | |
| 86 | window if it is not active. If it is deactivated, <code>deactivate()</code> | |
| 87 | is called with the button name or <strong>None</strong> as described above. The default is <strong>None</strong>.</p> | |

| 123 | width will be created between the button box and the child site, | |
| 124 | as a component named <strong>separator</strong>. Since the default border of the | |
| 125 | button box and child site is <strong>raised</strong>, this option does not | |
| 126 | usually need to be set for there to be a visual separation between | |
| 127 | the button box and child site. The default is <strong>0</strong>.</p> | |

| 155 | This is the child site for the dialog, which may be used to | |
| 156 | specialise the megawidget by creating other widgets within it. By | |
| 157 | default it is created with the options | |
| 158 | <code>(borderwidth = 1, relief = 'raised')</code>. By default, this component is a Tkinter.Frame.</p> | |

| 181 | If the <strong>separatorwidth</strong> initialisation option is non-zero, the | |
| 182 | <strong>separator</strong> component is the line dividing the area between the | |
| 183 | button box and the child site. By default, this component is a Tkinter.Frame.</p> | |
