QtScript script text editor for Qt 4.4.3 with Syntax Highlighter

Hi!

I'am building app with QtScript support, but for QtScript I not found standart editor control with Syntax Highlighter.

(QSA has syntax highliter text editor by default)

Is it possible to find any third party opensource script editor control for QtScript?

Hey!

1. Build your own Syntaxhighlighter as is described in Qt's Syntaxhighlighter example.
See my other post:
http://www.qtcentre.org/forum/f-qt-p...ter-25483.html

and add something like this:

Code:

---

class JSHighlighter : public MultiLineCommentHighlighter {    Q_OBJECT
 public:
     JSHighlighter(QTextDocument *parent = 0);
 };
 
  JSHighlighter::JSHighlighter(QTextDocument *parent) : MultiLineCommentHighlighter(parent)
 {
     QTextCharFormat keywordFormat;
     keywordFormat.setForeground(Qt::black);
     keywordFormat.setFontWeight(QFont::Bold);
     QStringList keywordPatterns;
     keywordPatterns << "\\bvar\\b" << "\\bArray\\b" << "\\bfunction\\b"
                     << "\\breturn\\b" << "\\barguments\\b" << "\\bif\\b"
                     << "\\belse\\b" << "\\bfor\\b" << "\\bswitch\\b"
                     << "\\bcase\\b" << "\\bbreak\\b" << "\\bwhile\\b";
     int i = 0;
     foreach (const QString &pattern, keywordPatterns) {
         SetRule(QString("00_KeyWord_%1").arg(i),pattern,keywordFormat);
         ++i;
     }
      // Values
     QTextCharFormat valueFormat;
     valueFormat.setForeground(Qt::blue);
     SetRule("03_Values","\\btrue\\b|\\bfalse\\b|\\b[0-9]+\\b",valueFormat);
      QTextCharFormat functionFormat;
     //functionFormat.setFontItalic(false);
     functionFormat.setForeground(Qt::darkBlue);
     SetRule("04_Functions","\\b[A-Za-z0-9_]+(?=\\()",functionFormat);
     // Qt Classes
     classFormat.setFontWeight(QFont::Bold);
     classFormat.setForeground(Qt::darkMagenta);
     SetRule("06_QtClasses","\\bQ[A-Z]+[A-Za-z]+\\b",classFormat);
      // Quotation
     QTextCharFormat quotationFormat;
     quotationFormat.setForeground(Qt::blue);
     SetRule("z1_Quotations","\"[^\"]*\"",quotationFormat);
      // Single Line Comments
     QTextCharFormat singleLineCommentFormat;
     singleLineCommentFormat.setForeground(Qt::darkGreen);
     SetRule("z2_SingleLineComments","//[^\n]*",singleLineCommentFormat);
 }

That's of course a bit ugly, but works for me.

2. Use the QScriptEngineDebugger. That even features code completition. But that works only for scripts beeing executed/loaded in the engine I think. So that's nothing for offline editing. See the Qt Script Debugger manual in the Qt Help.

3. Look into CodeEdit: http://www.qtcentre.org/forum/f-qt-b...edit-3178.html

I wonder where you have seen QScriptEngineDebugger can be used to even edit code.
The codeWidget is read-only, and the Qt doc states that

The code widget is read-only; it cannot currently be used to edit and (re)evaluate scripts.

Uuh. My fault! At the time I looked at

http://doc.trolltech.com/qq/qq02-fun...tionsdeveloper

and thought, that it was an example of the script engine debugger. But thats an old story for QSA!

Misleading title though :-> Sorry!

The best open source JavaScript syntax highlighter you can find is the one written by Nokia for QtCreator.
