QTextCursor

[Dmon]

How can I write a function that will search through a QTextEdit that contains a .txt file for example and then find all email addresses and phone numbers and change them to bold? I am told that I need to use QTextCursor somehow to do this.

This is what I have so far:
@void MakeDisplay::processDoc(){
QTextDocument doc = text->toPlainText();
QTextCursor cursor(text->textCursor());
for (int i=0;i < doc.size();i++)
{
cursor.setPosition(i-1,0);
if (doc[i] = '@')
{
cursor.blockFormat()
}
}

}

now changed to:

@void MakeDisplay::processDoc(){
QString doc = text->toPlainText();
QTextCursor cursor = text->textCursor();
QTextCharFormat format;
format.setFontWeight(75);
for (int i=0;i < doc.size();i++)
{
if (doc[i] == '@')
{
cursor.select(QTextCursor::WordUnderCursor);
cursor.setPosition(i, QTextCursor::MoveAnchor);
cursor.setPosition(i, QTextCursor::KeepAnchor);
cursor.mergeCharFormat(format);

    }
}

}@

which does not work, but at least compiles with no errors :D
