I can't replace "<" to "<"

Brikinhos

It's simple

 QString text= "This is a message test < > < > > > < < < <<< >> jan<d>epora";
 text.replace("<","&lt;");

It's doesn't work, but with "&l;" or other word it works. Is this a bug?

Thanks in advance

Hi,

What do you mean by doesn't work ? What output are you expecting ?

@SGaist Hi, i expect this output:

"This is a message test &lt; > &lt; > > > &lt; &lt; &lt; &lt;&lt;&lt; >> jan&lt;d>epora";

It's incredible, but it works replacing with other word.

@SGaist Ahhhh, damn, i know what is the $%&/ problem, i use this to test my program:

QMessageBox::information(0,"Test",text);

If i use:

QMessageBox::information(0,"Test","&lt;");

the output is "<"

Damn, 3 hours for this, i hate and love Qt

@SGaist Ahhhh, damn, i know what is the $%&/ problem, i use this to test my program:

This is documented in the QMessageBox class reference (see the section called "Rich Text and the Text Format Property").

Anyway, I recommend converting with QString::toHtmlEscaped() and testing with qDebug():

#include <QDebug>

// ...

QString text = "This is a message test < > < > > > < < < <<< >> jan<d>epora";
qDebug() << text.toHtmlEscaped();

@JKSH Thank you very much, it works with qDebug()

I can't replace "<" to "&lt;"
