How to dump the dom in Qt Script?

Question

Good afternoon,

I’ve connected the Qt (4.8) script engine up within my application. I’m still learning how to make my application accessible from scripts. I’d like to debug it by enumerating everything the script engine can see. Has anyone else already developed this?

The documentation says this should work, but it doesn’t (findChildren() is not defined):

var _children = findChildren();
 for (var i = 0; i < _children.length; ++i)
    serialize( _children[i], indentation + '   ' );

Here’s what I have so far:

var toType = function(obj) {
  return ({}).toString.call(obj).match(/\s([a-zA-Z]+)/)[1].toLowerCase()
}
// recursively display object structure
function serialize(node, indentation) {
   var out = indentation + '<' + node + ' type="' + toType(node) + '"' + '>';
   if ( toType(node) == 'object' )
   {
      for ( var prop in node ) {
        out += '\n' + serialize( prop, indentation + '   ' );
      }
      out += '\n' + indentation + '</' + node + '>' + '\n';
   }
   else
      out += node.toString() + '</' + node + '>';
   return out;
}

serialize( Game, '' );

I do get a dump:

<ClientOgreController(name = "Game") type="object">
   <CameraMan type="string">CameraMan</CameraMan>
   <HudAnimationFinished() type="string">HudAnimationFinished()</HudAnimationFinished()>
   <SkeletonDebug() type="string">SkeletonDebug()</SkeletonDebug()>
   <update() type="string">update()</update()>
   <CameraBookmark() type="string">CameraBookmark()</CameraBookmark()>
   <CameraUp() type="string">CameraUp()</CameraUp()>
   <CameraDown() type="string">CameraDown()</CameraDown()>
   <CameraToTerrain() type="string">CameraToTerrain()</CameraToTerrain()>
   <CameraForward() type="string">CameraForward()</CameraForward()>
   <ScreenCapture() type="string">ScreenCapture()</ScreenCapture()>
   <PhysicsDebug() type="string">PhysicsDebug()</PhysicsDebug()>
   <CameraOrbit() type="string">CameraOrbit()</CameraOrbit()>
   <Execute(const char*) type="string">Execute(const char*)</Execute(const char*)>
   <DebugConsoleTextEntered(QString) type="string">DebugConsoleTextEntered(QString)</DebugConsoleTextEntered(QString)>
   <DebugConsole() type="string">DebugConsole()</DebugConsole()>
</ClientOgreController(name = "Game")>

There are some problems with it though:

• Child objects and slots are reported as strings (See “CameraMan” and “SkeletonDebug()” )

• Should I be exposing child objects as references or pointers?

  Q_PROPERTY( Mover* CameraMan READ getCameraMan )

Thanks
