qtextbrowser text view problem

[VRonin]

The problem in your screenshot is that the last row (setText) overrides everything done above. just remove that row.

how to use the QTextStream

replace QString output(pl.readAllStandardOutput()); with

QTextStream consoleStream(&pl);
const QString output  = consoleStream.readAll();

@VRonin nothing

@VRonin any other solution??

Hi,

You should add some checks to verify that the process did indeed run and it was successful.

@SGaist
it run successfully and output is on the side window.

[SGaist]

The fact that mediainfo runs successfully on the command line doesn't mean that it will necessarily run the way you expect it to with QProcess.

Are you sure the path to the media file you are using is correct ?
Is it a relative or are an absolute path ?
What if you use the recommended structure of calling QProcess::start with the command as first parameter and a QStringList with the options as second parameter ?
Did you actually checked that p1 starts successfully ?
Did you actually checked that p1 ends successfully ?

Hi
As for other solution.
Use a QplainTextEdit

and just sets its font to monospaced
ui->plainTextEdit->setFont( (QFontDatabase::systemFont(QFontDatabase::FixedFont)) );

[VRonin]

The only thing I can think of with QTextBrowser is that you are using a style sheet with a font that overrides the one we are setting

@VRonin
Yep something like that - as your code and test file just works
with output from same command on linux.

Also, i noticed one thing in code shown on GITHUB

QTextCursor textBrowCrsr(ui->tdetail->document());
    const int oldPos = textBrowCrsr.position();
    textBrowCrsr.movePosition(QTextCursor::End);
    QTextCharFormat textBrowFormat = textBrowCrsr.charFormat();
    textBrowFormat.setFont(QFontDatabase::systemFont(QFontDatabase::FixedFont));
    textBrowCrsr.insertText(output,textBrowFormat);
    textBrowCrsr.setPosition(oldPos);


    ui->tdetail->setText(output.toUtf8()); <<<<<<<<<<<<<<<<<< wont that override insertText ?

@mrjj it was a old commit .

@saber
ok.
I did make small test on linux and VRonin sample did in fact make
it uses fixed font so it looked correctly.
However, using plainTextEdit is a one liner so might be more optimal if you do not need the HTML textbrowse offer

[saber]

i do't know how to fix that or what's wrong.
after long works i made an app with mediainfo as backend.
here is the app CoreInfo.
thanks.
