how to create a sample HTML file using QFIle

Christian Ehrlicher

@ManiRon said in how to create a sample HTML file using QFIle:

I am unable to generate file

In which way? This is not very precise...

QTextDocument::toHtml

And ahy do you delete your topics?

ManiRon

@Christian-Ehrlicher sorry by mistake

ManiRon

@Christian-Ehrlicher I tried the way you mentioned but it creates file but doesnt have the contents.

ManiRon

@Christian-Ehrlicher this is my code

      QTextDocument qData1(&qHtmlFile);
qData1.setHtml(qRep);
        qData1.toHtml();

Christian Ehrlicher

How should the code above create a file when there is no QFile involved at all? Please be a little bit more careful and think by yourself before posting some useless stuff.

ManiRon

@Christian-Ehrlicher
I thought you would understand as i have mentioned the QFile in my first post itself so i thought its fine to just give the main part , is it fine now ?

QFile qHtmlFile("FilePath");
QTextDocument qData1(&qHtmlFile);
qData1.setHtml(qRep);
qData1.toHtml();

Christian Ehrlicher

Please read the docs - I gave you the links so you even don't have to search. This can't work at all...

ManiRon

@Christian-Ehrlicher ok sir, then how this can be done, I mean generating an html file.

ManiRon

@Christian-Ehrlicher any other idea if possible

Hi,

Use of QFile:

Create QFile variable
Call open
Check that open was successful
Call write
Close file

Done

ManiRon

@SGaist yes i tried it, I create a table using HTML . If i do as mentioned by you the table doesnt has the column seperator line .

@ManiRon Can you please show the code you're using now? And the content of the file you're generating (the text, not pictures)?

ManiRon

@jsulm

this whole code will be stored in a QString and this i am printing

<article><div align="right"></div><header><h1><center><font color="midnightblue"></font></center></h1><h2><font color="dimgray"></font></h2></header></article><table border="1" style="background-color:ghostwhite;border:1px dotted black;width:80%;border-collapse:collapse;"><tr style="background-color:gainsboro;color:black;"></table><style type="text/css">table.tbl {border-width: 1px;border-style: solid;border-color: black;margin-top: 0px;margin-bottom: 0px;color: black;}table.tbl td {padding: 3px;}table.tbl th {padding: 3px;font-size: 18px;}</style><table width="100%" cellspacing="0" class="tbl" style="border:1px solid black;border-collapse:collapse;" align = center ><tr><th><b><center><span style =font-size:10pt;>Application</span></center></b></th><th><b><center><span style =font-size:10pt;>Check Sum</span></center></b></th><th><b><center><span style =font-size:10pt;>Total</span></center></b></th><th><b><center><span style =font-size:10pt;>No</span></center></b></th><th><b><center><span style =font-size:10pt;>Tested By</span></center></b></th><th><b><center><span style =font-size:10pt;></span></center></b></th><th><b><center><span style =font-size:10pt;></span></center></b></th></tr><tr><td><center><span style =font-size:10pt;>1.00</span></center></td><td><center><span style =font-size:10pt;>123</span></center></td><td><center><span style =font-size:10pt;></span></center></td><td><center><span style =font-size:10pt;></span></center></td><td><center><span style =font-size:10pt;></span></center></td><td><center><span style =font-size:10pt;></span></center></td><td><center><span style =font-size:10pt;></span></center></td></tr></table><br><br><br><style type="text/css">table.tbl1 {border-width: 1px;border-style: solid;border-color: black;margin-top: 0px;margin-bottom: 0px;color: black;}table.tbl1 td {padding: 3px;}table.tbl1 th {padding: 3px;font-size: 18px;}</style><table width="100%" cellspacing="0" class="tbl1"><tr><th>Name</th><th>Data</th><th>data</th><th>Test Result</th></tr><tr><td><b><span style =font-size:10pt;>sss</span></b></td><td>Data1</td><td>Data2</td><td><b><span style =font-size:10pt;><font color=Green>PASS</font></span></b></td></tr></table><br><br><br><br><hr><br><br>

@ManiRon This is not valid HTML.
And by "code" I mean your C++ code to generate the HTML file...

ManiRon

@jsulm

QString qHostVer = "<b><center><span style =font-size:10pt;>Application</span></center></b>";

QString qCheckSum = "<b><center><span style =font-size:10pt;>123</span></center></b>";

QString qTotal= "<b><center><span style =font-size:10pt;>Total</span></center></b>";

QString qNo= "<b><center><span style =font-size:10pt;>No</span></center></b>";

QString qTestedBy = "<b><center><span style =font-size:10pt;>Tested By</span></center></b>";

         css1 = "<style type=\"text/css\">";
         css1 += "table.tbl {border-width: 1px;border-style: solid;border-color: black;margin-top: 0px;margin-bottom: 0px;color: black;}";
         css1 += "table.tbl td {padding: 3px;}";
         css1 += "table.tbl th {padding: 3px;font-size: 18px;}";
         css1+="</style>";
         text1 += "<table width=\"100%\" cellspacing=\"0\" class=\"tbl\" style=\"border:1px solid black;border-collapse:collapse;\" align = center >";
         text1 +=("<tr><th>"+qHostVer+"</th><th>"+qCheckSum+"</th><th>"+qTargetCheckSum+"</th>"\
                  "<th>"+qfont+"</th><th>"+qTestedBy+"</th></tr>");
        QString  text1 +=("<tr><td><center><span style =font-size:10pt;>" + 1.00 +"</span></center></td>"\
                  "<td><center><span style =font-size:10pt;>" + 123 +"</span></center></td>"\

qRep = css+text;

QFile qHtmlFile(file path);
qHtmlFile.write(qRep);
qHtmlFile.close();

@jsulm this code works fine when i use QTextbrowser, But i dont want to use QTextBrowser as it cannot be used inside a QThread

jsulm

@ManiRon You're not generating valid HTML

ManiRon

@jsulm so what change i should make

jsulm

@ManiRon This is how a HTML document should look like:

<html>
  <head>
   HEADER IF NEEDED 
  </head>
  <body>
    YOUR CONTENT HERE
  </body>
</html>

VRonin

Since you are hard coding stuff anyway, you can use QXmlStreamWriter directly on the QFile device to generate html:

QFile qHtmlFile("myFile.html");
if(qHtmlFile.open(QIODevice::WriteOnly){
QTextStream startDocStream(&qHtmlFile);
startDocStream << QStringLiteral("<!DOCTYPE html>");
QXmlStreamWriter htmlWriter(&qHtmlFile);
htmlWriter.writeStartElement(QStringLiteral("html"));
htmlWriter.writeAttribute(QStringLiteral("xmlns"),QStringLiteral("http://www.w3.org/1999/xhtml"));
htmlWriter.writeAttribute(QStringLiteral("lang"),QStringLiteral("en"));
htmlWriter.writeAttribute(QStringLiteral("xml"),QStringLiteral("lang"),QStringLiteral("en"));
htmlWriter.writeStartElement(QStringLiteral("head"));
htmlWriter.writeStartElement(QStringLiteral("meta"));
htmlWriter.writeAttribute(QStringLiteral("http-equiv"),QStringLiteral("Content-Type"));
htmlWriter.writeAttribute(QStringLiteral("content"),QStringLiteral("text/html; charset=utf-8"));
htmlWriter.writeEndElement(); //meta
htmlWriter.writeStartElement(QStringLiteral("title"));
htmlWriter.writeCharacters(QStringLiteral("Test Page"));
htmlWriter.writeEndElement(); //title
htmlWriter.writeStartElement(QStringLiteral("style"));
htmlWriter.writeCharacters(QStringLiteral("h1, h2, h3, h4 { color: rgb(83,129,53) } h1 { text-align: center; }"));
htmlWriter.writeEndElement(); //style
htmlWriter.writeEndElement(); //head
htmlWriter.writeStartElement(QStringLiteral("body"));
htmlWriter.writeStartElement(QStringLiteral("h1"));
htmlWriter.writeCharacters(QStringLiteral("Test Page"));
htmlWriter.writeEndElement(); //h1
htmlWriter.writeStartElement(QStringLiteral("h2"));
htmlWriter.writeCharacters(QStringLiteral("Lorem"));
htmlWriter.writeEndElement(); //h2
htmlWriter.writeStartElement(QStringLiteral("p"));
htmlWriter.writeCharacters(QStringLiteral("Lorem ipsum dolor sit amet, consectetur adipiscing elit."));
htmlWriter.writeEndElement(); //p
htmlWriter.writeEndElement(); //body
htmlWriter.writeEndElement(); //html
}
