| 84 /** | |
| 85 * This class is a read-only text control that is capable of rendering wrapped | |
| 86 * text. Text can be rendered as-is or by parsing the formatting XML tags. | |
| 87 * Independently, words that start with http:// can be converted into hyperlinks | |
| 88 * on the fly. | |
| 89 * <p> | |
| 90 * When configured to use formatting XML, the control requires the root element | |
| 91 * <code>form</code> to be used. The following tags can be children of the | |
| 92 * <code>form</code> element: | |
| 93 * </p> | |
| 94 * <ul> | |
| 95 * <li><b>p </b>- for defining paragraphs. The following attributes are | |
| 96 * allowed: | |
| 97 * <ul> | |
| 98 * <li><b>vspace </b>- if set to 'false', no vertical space will be added | |
| 99 * (default is 'true')</li> | |
| 100 * </ul> | |
| 101 * </li> | |
| 102 * <li><b>li </b>- for defining list items. The following attributes are | |
| 103 * allowed: | |
| 104 * <ul> | |
| 105 * <li><b>vspace </b>- the same as with the <b>p </b> tag</li> | |
| 106 * <li><b>style </b>- could be 'bullet' (default), 'text' and 'image'</li> | |
| 107 * <li><b>value </b>- not used for 'bullet'. For text, it is the value of the | |
| 108 * text that is rendered as a bullet. For image, it is the href of the image to | |
| 109 * be rendered as a bullet.</li> | |
| 110 * <li><b>indent </b>- the number of pixels to indent the text in the list item | |
| 111 * </li> | |
| 112 * <li><b>bindent </b>- the number of pixels to indent the bullet itself</li> | |
| 113 * </ul> | |
| 114 * </li> | |
| 115 * </ul> | |
| 116 * <p> | |
| 117 * Text in paragraphs and list items will be wrapped according to the width of | |
| 118 * the control. The following tags can appear as children of either <b>p </b> or | |
| 119 * <b>li </b> elements: | |
| 120 * <ul> | |
| 121 * <li><b>img </b>- to render an image. Element accepts attribute 'href' that | |
| 122 * is a key to the <code>Image</code> set using 'setImage' method. Vertical | |
| 123 * position of image relative to surrounding text is optionally controlled by | |
| 124 * the attribute <b>align</b> that can have values <b>top</b>, <b>middle</b> | |
| 125 * and <b>bottom</b></li> | |
| 126 * <li><b>a </b>- to render a hyperlink. Element accepts attribute 'href' that | |
| 127 * will be provided to the hyperlink listeners via HyperlinkEvent object. The | |
| 128 * element also accepts 'nowrap' attribute (default is false). When set to | |
| 129 * 'true', the hyperlink will not be wrapped. Hyperlinks automatically created | |
| 130 * when 'http://' is encountered in text are not wrapped.</li> | |
| 131 * <li><b>b </b>- the enclosed text will use bold font.</li> | |
| 132 * <li><b>br </b>- forced line break (no attributes).</li> | |
| 133 * <li><b>span </b>- the enclosed text will have the color and font specified | |
| 134 * in the element attributes. Color is provided using 'color' attribute and is a | |
| 135 * key to the Color object set by 'setColor' method. Font is provided using | |
| 136 * 'font' attribute and is a key to the Font object set by 'setFont' method. As with | |
| 137 * hyperlinks, it is possible to block wrapping by setting 'nowrap' to true | |
| 138 * (false by default). | |
| 139 * </li> | |
| 140 * <li><b>control (new in 3.1)</b> - to place a control that is a child of the | |
| 141 * text control. Element accepts attribute 'href' that is a key to the Control | |
| 142 * object set using 'setControl' method. Optionally, attribute 'fill' can be set | |
| 143 * to <code>true</code> to make the control fill the entire width of the text. | |
| 144 * Form text is not responsible for creating or disposing controls, it only | |
| 145 * places them relative to the surrounding text. Similar to <b>img</b>, | |
| 146 * vertical position of the control can be set using the <b>align</b> | |
| 147 * attribute. In addition, <b>width</b> and <b>height</b> attributes can | |
| 148 * be used to force the dimensions of the control. If not used, | |
| 149 * the preferred control size will be used. | |
| 150 * </ul> | |
| 151 * <p> | |
| 152 * None of the elements can nest. For example, you cannot have <b>b </b> inside | |
| 153 * a <b>span </b>. This was done to keep everything simple and transparent. | |
| 154 * Since 3.1, an exception to this rule has been added to support nesting images | |
| 155 * and text inside the hyperlink tag (<b>a</b>). Image enclosed in the | |
| 156 * hyperlink tag acts as a hyperlink, can be clicked on and can accept and | |
| 157 * render selection focus. When both text and image is enclosed, selection and | |
| 158 * rendering will affect both as a single hyperlink. | |
| 159 * </p> | |
| 160 * <p> | |
| 161 * Since 3.1, it is possible to select text. Text selection can be | |
| 162 * programmatically accessed and also copied to clipboard. Non-textual objects | |
| 163 * (images, controls etc.) in the selection range are ignored. | |
| 164 * <p> | |
| 165 * Care should be taken when using this control. Form text is not an HTML | |
| 166 * browser and should not be treated as such. If you need complex formatting | |
| 167 * capabilities, use Browser widget. If you need editing capabilities and | |
| 168 * font/color styles of text segments is all you need, use StyleText widget. | |
| 169 * Finally, if all you need is to wrap text, use DWT Label widget and create it | |
| 170 * with DWT.WRAP style. | |
