This is particularly - useful if you want to display some rich text in a custom widget. A - TQStyleSheet is needed to interpret the tags and format the rich - text. TQt provides a default HTML-like style sheet, but you may - define custom style sheets. - - Once created, the rich text object can be queried for its width(), - height(), and the actual width used (see widthUsed()). Most - importantly, it can be drawn on any given TQPainter with draw(). - TQSimpleRichText can also be used to implement hypertext or active - text facilities by using anchorAt(). A hit test through inText() - makes it possible to use simple rich text for text objects in - editable drawing canvases. - - Once constructed from a string the contents cannot be changed, - only resized. If the contents change, just throw the rich text - object away and make a new one with the new contents. - - For large documents use TQTextEdit or TQTextBrowser. For very small - items of rich text you can use a TQLabel. - - If you are using TQSimpleRichText to print in high resolution you - should call setWidth(TQPainter, int) so that the content will be - laid out properly on the page. -*/ - -/*! - Constructs a TQSimpleRichText from the rich text string \a text and - the font \a fnt. - - The font is used as a basis for the text rendering.

This - becomes important if \a text contains relative references, for - example within image tags.
