[Qt-interest] Passing QList<QStringList> as arguments

[David Villalobos Cambronero]

Thanks for the interest Eric, here is the info.

Header file
------------------------------------------------------------------------------------------------------------------------
#ifndef MYSQLTOPCLASS_H
#define MYSQLTOPCLASS_H

class QList<QStringList *>;

class mysqlTopClass
{
public:
    mysqlTopClass();
    QString outputAsTable(const QStringList *headers, const
QList<QStringList> *rows);
};

#endif // MYSQLTOPCLASS_H
------------------------------------------------------------------------------------------------------------------------

Class file
------------------------------------------------------------------------------------------------------------------------
#include <QStringList>
#include <QList>

#include "mysqltopclass.h"

mysqlTopClass::mysqlTopClass()
{
}

QString mysqlTopClass::outputAsTable(const QStringList *headers, const
QList<QStringList> *rows)
{
  return "Gelow";
}
------------------------------------------------------------------------------------------------------------------------

Here is where I use it
------------------------------------------------------------------------------------------------------------------------

#include <QtGui>

#include "serverInformation.h"
#include "mysqlClasses/mysql.h"
#include "ui_dialog.h"

serverInformation::serverInformation()
{
  mysql *conn = new mysql;

  QStringList *headers = new QStringList("-V,(**.)");
  headers->append("David");
  headers->append("Vil");
  headers->append("Vil");
  QList<QStringList> *rows = new QList<QStringList *>;
  rows->append(new QStringList("David V"));
  QPlainTextEdit *replicationStatus = new
QPlainTextEdit(conn->outputAsTable(headers, rows));
  replicationStatus->setFont(font);
  replicationStatus->setWordWrapMode(QTextOption::NoWrap);
  addTab(replicationStatus, QIcon(":/images/images/16/Replication.png"),
tr("Replication Status"));
}


Hope it helps. If not, I can send you a copy of my project.
