Rutin to log the actual widget tree

I just share these routines that I use for debugging purposes:

The first is to show the widget variable name on the GUI when mouse pointer is hold over a widget:

#define DebugTooltip(vName) vName->setAttributeValue("title",#vName)

void myApplication::AddWidgetStructureDebugTitles(){
  DebugTooltip(firstLine_CW);
  DebugTooltip(secondLine_CW);
  DebugTooltip(siaLogo_Img);
  // .......
  DebugTooltip(Feedback_OMF);
}

The second routine logs the widget tree structure (starting with the widget received as a parameter), using the title attributes set by the previous routine:

void myApplication::ListWidgets(WWebWidget *startPoint, long Counter){
  WWebWidget      *thisWebWidget;
  WTabWidget      *thisTabWidget;
  std::string      thisTypeName;
  std::string      thisMessage;
  std::string      spaces("                                                "); // 48 space chars
  char             Buf[17];
  std::vector< WWidget * > WidgetList;
  WidgetList = startPoint->children();
  for (vector<WWidget *>::iterator it = WidgetList.begin(); it != WidgetList.end(); ++it) {
    thisWebWidget = (WWebWidget *)*it;
    thisTypeName = typeid(*thisWebWidget).name();
    sprintf(Buf,"%02ld",Counter);
    thisMessage = Buf + (string)". " + spaces.substr(0, (Counter - 1) * 2) + thisTypeName;
    thisMessage = thisMessage + spaces.substr(0, max(1, (40 - thisMessage.length())));
    if (thisTypeName == "class Wt::WTabWidget") {
      thisTabWidget = (WTabWidget *)*it;
      wApp->log("Info:") << thisMessage << " / " << thisTabWidget->attributeValue("title");
      short tabCount = thisTabWidget->count();
      for (short i = 0; i < tabCount; i++) {
        thisWebWidget = (WWebWidget *)(thisTabWidget->widget(i));
        thisTypeName = typeid(*thisWebWidget).name();
        thisMessage = Buf + (string)". " + spaces.substr(0, (Counter - 1) * 2) + thisTypeName;
        thisMessage = thisMessage + spaces.substr(0, max(1, (40 - thisMessage.length())));
        wApp->log("Info:") << thisMessage << " / " << thisWebWidget->attributeValue("title");
        if (thisWebWidget->children().size() > 0) {
          ListWidgets(thisWebWidget, Counter + 1);
        }
      }
    } else {
      wApp->log("Info:") << thisMessage << " / " << thisWebWidget->attributeValue("title");
      if (thisWebWidget->children().size() > 0) {
        ListWidgets(thisWebWidget, Counter + 1);
      }
    }
  }
}

Feel free to use it.
