Printing white spaces in QTextEdit

[A Former User]

Hi, i want to see the White spaces. For example a Point for space, an arrow for tab and so on.

    QTextOption option;
    option.setFlags(QTextOption::ShowLineAndParagraphSeparators | QTextOption::ShowTabsAndSpaces);
    doc->setDefaultTextOption(option);

This doesn't work, why?

Please help me. Thanks

Henrik

Hi Henrik,

It should work ok, did you set the document into the QTextEdit using this method?

QTextEdit::setDocument;

This code worked for me:

    QTextEdit *te = new QTextEdit(this);
    QTextDocument* doc = new QTextDocument(this);
    te->setDocument(doc);
    te->insertPlainText("  test\n");

    QTextOption option;
    option.setFlags(QTextOption::ShowLineAndParagraphSeparators | QTextOption::ShowTabsAndSpaces);
    doc->setDefaultTextOption(option);
