Syntax highlighters are often used when the user is - entering text in a specific format (for example, source code) and - help the user to read the text and identify syntax errors. - - To provide your own syntax highlighting for TQTextEdit, you must - subclass TQSyntaxHighlighter and reimplement highlightParagraph(). - - When you create an instance of your TQSyntaxHighlighter subclass, - pass it the TQTextEdit that you want the syntax highlighting to be - applied to. After this your highlightParagraph() function will be - called automatically whenever necessary. Use your - highlightParagraph() function to apply formatting (e.g. setting - the font and color) to the text that is passed to it. -*/ - -/*! - Constructs the TQSyntaxHighlighter and installs it on \a textEdit. - - It is the caller's responsibility to delete the - TQSyntaxHighlighter when it is no longer needed. -*/ - -TQSyntaxHighlighter::TQSyntaxHighlighter( TQTextEdit *textEdit ) - : para( 0 ), edit( textEdit ), d( new TQSyntaxHighlighterPrivate ) -{ - textEdit->document()->setPreProcessor( new TQSyntaxHighlighterInternal( this ) ); - textEdit->document()->tqinvalidate(); - TQTimer::singleShot( 0, textEdit->viewport(), TQT_SLOT( update() ) ); -} - -/*! - Destructor.

Your function must return a value - which indicates the paragraph's end state: see below. - - Some syntaxes can have constructs that span paragraphs. For - example, a C++ syntax highlighter should be able to cope with - \c{/}\c{*...*}\c{/} comments that span paragraphs. To deal - with these cases it is necessary to know the end state of the - previous paragraph (e.g. "in comment"). - - If your syntax does not have paragraph spanning constructs, simply - ignore the \a endStateOfLastPara parameter and always return 0. - - Whenever highlightParagraph() is called it is passed a value for - \a endStateOfLastPara. For the very first paragraph this value is - always -2. For any other paragraph the value is the value returned - by the most recent highlightParagraph() call that applied to the - preceding paragraph. - - The value you return is up to you. We recommend only returning 0 - (to signify that this paragraph's syntax highlighting does not - affect the following paragraph), or a positive integer (to signify - that this paragraph has ended in the middle of a paragraph - spanning construct). - - To find out which paragraph is highlighted, call - currentParagraph(). - - For example, if you're writing a simple C++ syntax highlighter, - you might designate 1 to signify "in comment". For a paragraph - that ended in the middle of a comment you'd return 1, and for - other paragraphs you'd return 0. In your parsing code if \a - endStateOfLastPara was 1, you would highlight the text as a C++ - comment until you reached the closing \c{*}\c{/}. -*/ - -/*! - This function is applied to the syntax highlighter's current - paragraph (the text of which is passed to the highlightParagraph() - function). - - The specified \a font and \a color are applied to the text from - position \a start for \a count characters.
