<![CDATA[Need help to display the preview of the content of file in text browser]]>This is my code snippet:

@
void MainWindow::on_filteredTreeView_clicked(const QModelIndex &index)
{
QString strIndex = index.data(QFileSystemModel::FilePathRole).toString();
QFile file(strIndex);
QFileInfo fileInfo(strIndex);

if (fileInfo.suffix() == "txt")
{
    file.open(QIODevice::ReadOnly);
    QTextStream in(&file);
    ui->textBrowser->setText(in.readAll());
    file.close();
}

}
@

I just managed to extract the content of .txt file only to be display in the text browser.
How do I want to extract the content of other file extension such as .jpg, .docx and others?

But in the application output, it says:
"QFSFileEngine::open: No file name specified"

Can someone explain the this error?

This is my code snippet:
@
else if (fileInfo.suffix() == "jpg" || fileInfo.suffix() == "gif" || fileInfo.suffix() == "png" || fileInfo.suffix() == "tiff" || fileInfo.suffix() == "tiff")
{
QString strPre = QString("<img /> ");
ui->textBrowser->setHtml(strPre);
}
@

Edited: Suppose in the line 3, I wrote like this,
src="" + fileInfo.filePath() + "" after "img" and before "/>".

I don't know why it don't want to appear.

See example "here":http://qt-project.org/doc/qt-5/qtextedit.html#drag-and-drop

But it is much easier to display an image on a QLabel.

That means I want to see the image on the text browser.
I don't want to do any change to the property of date modified of the file.
That's why I using read only when I want to read .txt file.
Does the text browser can display the image of .jpg?
Or the text browser can display a bundle of text only?

That depends on what you want to see in there. Binary data? EXIF information? Some basic picture properties (size, color depth)?

All those are possible, but need to be implemented in a different way.
