| 27 | <p> | |
| 28 | A scrolled frame consists of a scrollable interior frame within a | |
| 29 | clipping frame. The programmer can create other widgets within | |
| 30 | the interior frame. If the frame becomes larger than the | |
| 31 | surrounding clipping frame, the user can position the frame using | |
| 32 | the horizontal and vertical scrollbars.</p> | |
| 33 | ||
| 34 | <p> The scrollbars can be <em>dynamic</em>, which means that a scrollbar will | |
| 35 | only be displayed if it is necessary. That is, if the frame is | |
| 36 | smaller than the surrounding clipping frame, the scrollbar will be | |
| 37 | hidden.</p> | |

| 61 | of the clipping frame, the interior frame expands to fill the | |
| 62 | clipping frame. If <strong>'shrink'</strong> and the requested width of the | |
| 63 | interior frame is more than the width of the clipping frame, the | |
| 64 | interior frame shrinks to the width of the clipping frame. If | |

| 103 | <strong>None</strong>, it should be a concatenation of one or two of the | |
| 104 | letters <strong>'n'</strong>, <strong>'s'</strong>, <strong>'e'</strong> and <strong>'w'</strong>. The first letter | |
| 105 | specifies on which side of the megawidget to place the label. | |
| 106 | If a second letter is specified, it indicates where on that | |
| 107 | side to place the label. For example, if <strong>labelpos</strong> is <strong>'w'</strong>, | |
| 108 | the label is placed in the center of the left hand side; if | |
| 109 | it is <strong>'wn'</strong>, the label is placed at the top of the left | |
| 110 | hand side; if it is <strong>'ws'</strong>, the label is placed at the | |
| 111 | bottom of the left hand side.</p> | |

| 179 | <a name=component.borderframe></a> | |
| 180 | <dl><dt> <strong>borderframe | |
| 181 | </strong></dt><dd> | |
| 182 | A frame widget which snuggly fits around the clipper, to give the | |
| 183 | appearance of a border. It is created with a border so that the | |
| 184 | clipper, which is created without a border, looks like it has a | |
| 185 | border. By default, this component is a Tkinter.Frame.</p> | |
| 186 | ||

| 189 | <a name=component.clipper></a> | |
| 190 | <dl><dt> <strong>clipper | |
| 191 | </strong></dt><dd> | |
| 192 | The frame which is used to provide a clipped view of the <strong>frame</strong> | |
| 193 | component. If the <strong>borderframe</strong> option is true, this is created | |
| 194 | with a borderwidth of <strong>0</strong> to overcome a known problem with using | |
| 195 | <code>place</code> to position widgets: if a widget (in this case the | |
| 196 | <strong>frame</strong> component) is <code>placed</code> inside a frame (in this case the | |
| 197 | <strong>clipper</strong> component) and it extends across one of the edges of the | |
| 198 | frame, then the widget obscures the border of the frame. | |
| 199 | Therefore, if the clipper has no border, then this overlapping | |
| 200 | does not occur. By default, this component is a Tkinter.Frame.</p> | |

| 211 | <a name=component.horizscrollbar></a> | |
| 212 | <dl><dt> <strong>horizscrollbar | |

| 221 | This acts as the body for the entire megawidget. Other components | |
| 222 | are created as children of the hull to further specialise this | |
| 223 | class. By default, this component is a Tkinter.Frame.</p> | |

| 229 | </strong></dt><dd> | |
| 230 | If the <strong>labelpos</strong> option is not <strong>None</strong>, this component is | |
| 231 | created as a text label for the megawidget. See the | |
| 232 | <strong>labelpos</strong> option for details. Note that to set, for example, | |
| 233 | the <strong>text</strong> option of the label, you need to use the <strong>label_text</strong> | |
| 234 | component option. By default, this component is a Tkinter.Label.</p> | |

| 248 | Only methods specific to this megawidget are described below. | |
| 249 | For a description of its inherited methods, see the | |
| 250 | manual for its base class | |

| 252 | <p></p> | |
| 253 | <a name=method.interior></a> | |
| 254 | <dl><dt> <strong>interior</strong>()</dt><dd> | |
| 255 | Return the frame within which the programmer may create widgets to | |
| 256 | be scrolled. This is the same as <code>component('frame')</code>.</p> | |
| 257 | ||
| 258 | ||
| 259 | </dd></dl> | |
| 260 | <a name=method.reposition></a> | |
| 261 | <dl><dt> <strong>reposition</strong>()</dt><dd> | |
| 262 | Update the position of the <strong>frame</strong> component in the <strong>clipper</strong> and | |
| 263 | update the scrollbars.</p> | |
| 264 | <p> Usually, this method does not need to be called explicitly, since | |
| 265 | the position of the <strong>frame</strong> component and the scrollbars are | |
| 266 | automatically updated whenever the size of the <strong>frame</strong> or | |
| 267 | <strong>clipper</strong> components change or the user clicks in the scrollbars. | |
| 268 | However, if <strong>horizflex</strong> or <strong>vertflex</strong> is <strong>'expand'</strong>, the | |
| 269 | megawidget cannot detect when the requested size of the <strong>frame</strong> | |
| 270 | increases to greater than the size of the <strong>clipper</strong>. Therefore, | |
| 271 | this method should be called when a new widget is added to the | |
| 272 | <strong>frame</strong> (or a widget is increased in size) <em>after</em> the initial | |
| 273 | megawidget construction.</p> | |

| 281 | frame. If <em>mode</em> is <strong>None</strong>, return a tuple of two numbers, each | |
| 282 | between 0.0 and 1.0. The first is the position of the left edge | |
| 283 | of the visible region of the contents of the scrolled frame, | |
| 284 | expressed as a fraction of the total width of the contents. The | |
| 285 | second is the position of the right edge of the visible region.</p> | |
