How to display the output of the program mentioned below using a textBrowser ?

Jayashri

This program displays the output in a message box but instead I want it in a TextBrowser...

#include "mainwindow.h"
#include "ui_mainwindow.h"
#include <QTextStream>
#include <QMessageBox>
#include <QFileDialog>
#include <QDebug>
#include "dia.h"
#include"dai2.h"

MainWindow::MainWindow(QWidget* parent) :
QMainWindow(parent),
ui(new Ui::MainWindow) {
ui->setupUi(this);
}

MainWindow::~MainWindow() {
delete ui;
}

#include <QFile>

void CompareRule1(int cline,QString OnePara ) {

// check the rules
if (OnePara.contains("//"))
QMessageBox::warning(NULL, "My Application", QString("line %1 -ERROR.\nRule 1 Violated !").arg(cline) );

}
void CompareRule2(int cline,QString OnePara ) {

// check the rules
if (OnePara.contains("hai"))
QMessageBox::warning(NULL, "My Application", QString("line %1 -ERROR.\nRule 2 Violated !").arg(cline) );

}

void MainWindow::on_pushButton_clicked()
{
QString fileName = QFileDialog::getOpenFileName(this, tr("Opentext File"),
QDir::currentPath(),
tr("text Files (*.txt)"));
if (fileName.isEmpty()) {
return;
}
else
{
dia d;
d.setModal(false);
d.exec();

}
QFile inputFile(fileName);
QString Para;
int lineCount = 0;
if (inputFile.open(QIODevice::ReadOnly)) {
  QTextStream in(&inputFile);
  while (!in.atEnd())
  {
       lineCount++;
    QString line = in.readLine();
    qDebug() << lineCount << line;
    Para += line;
    qDebug()<<line;
    qDebug()<<Para;
    if (line!=NULL) { // we found blank line, so test and clear
             (CompareRule1(lineCount,line));
              (CompareRule2(lineCount,line));



                        qDebug() << "ParaRead: " << Para;
      Para = ""; //clear

  }
  }
  inputFile.close();
}

}

Hi

You can write the messages you display with QMessageBox into a QTextDocument and display this QTextDocument with QTextBrowser

QTextBrowser *browser = new QTextBrowser;
//...
browser->setDocument(new QTextDocument("<your message here>");
