Examples of org.eclipse.ui.forms.widgets.FormText

org.eclipse.ui.forms.widgets.FormText
be converted into hyperlinks on the fly.
When configured to use formatting XML, the control requires the root element form to be used. The following tags can be children of the form element:
- p - for defining paragraphs. The following attributes are allowed:
  - vspace - if set to 'false', no vertical space will be added (default is 'true')
- li - for defining list items. The following attributes are allowed:
  - vspace - the same as with the p tag
  - style - could be 'bullet' (default), 'text' and 'image'
  - value - not used for 'bullet'. For text, it is the value of the text that is rendered as a bullet. For image, it is the href of the image to be rendered as a bullet.
  - indent - the number of pixels to indent the text in the list item
  - bindent - the number of pixels to indent the bullet itself
Text in paragraphs and list items will be wrapped according to the width of the control. The following tags can appear as children of either p or li elements:
- img - to render an image. Element accepts attribute 'href' that is a key to the Image set using 'setImage' method. Vertical position of image relative to surrounding text is optionally controlled by the attribute align that can have values top, middle and bottom
- a - to render a hyperlink. Element accepts attribute 'href' that will be provided to the hyperlink listeners via HyperlinkEvent object. The element also accepts 'nowrap' attribute (default is false). When set to 'true', the hyperlink will not be wrapped. Hyperlinks automatically created when 'http://' is encountered in text are not wrapped.
- b - the enclosed text will use bold font.
- br - forced line break (no attributes).
- span - the enclosed text will have the color and font specified in the element attributes. Color is provided using 'color' attribute and is a key to the Color object set by 'setColor' method. Font is provided using 'font' attribute and is a key to the Font object set by 'setFont' method. As with hyperlinks, it is possible to block wrapping by setting 'nowrap' to true (false by default).
- control (new in 3.1) - to place a control that is a child of the text control. Element accepts attribute 'href' that is a key to the Control object set using 'setControl' method. Optionally, attribute 'fill' can be set to true to make the control fill the entire width of the text. Form text is not responsible for creating or disposing controls, it only places them relative to the surrounding text. Similar to img, vertical position of the control can be set using the align attribute. In addition, width and height attributes can be used to force the dimensions of the control. If not used, the preferred control size will be used.
None of the elements can nest. For example, you cannot have b inside a span . This was done to keep everything simple and transparent. Since 3.1, an exception to this rule has been added to support nesting images and text inside the hyperlink tag (a). Image enclosed in the hyperlink tag acts as a hyperlink, can be clicked on and can accept and render selection focus. When both text and image is enclosed, selection and rendering will affect both as a single hyperlink.

Since 3.1, it is possible to select text. Text selection can be programmatically accessed and also copied to clipboard. Non-textual objects (images, controls etc.) in the selection range are ignored.
Care should be taken when using this control. Form text is not an HTML browser and should not be treated as such. If you need complex formatting capabilities, use Browser widget. If you need editing capabilities and font/color styles of text segments is all you need, use StyleText widget. Finally, if all you need is to wrap text, use SWT Label widget and create it with SWT.WRAP style. @see FormToolkit @see TableWrapLayout @since 3.0
