QPlainTextEdit highlight word

[ArkKup]

Hi,

In my texteditor application I'd like to highlight all occurrence of a word under cursor. The problem is that it works for all lines except highlighted line.

void CodeEditor::test()
{
highlightCurrentLine(); //function based on CodeEditor example
highlightCurrentWord("bar");
}
 
void CodeEditor::highlightCurrentWord(QString curWord)
{
QTextCharFormat fmt;
fmt.setBackground(Qt::red);
fmt.setForeground(Qt::black);
//...
QTextCursor cursor = QTextCursor(block);
cursor.select(QTextCursor::WordUnderCursor);
//...
cursor.setPosition(begin, QTextCursor::MoveAnchor);
cursor.setPosition(end, QTextCursor::KeepAnchor);
cursor.mergeCharFormat(fmt); //I did try also cursor.setCharFormat(fmt);
//...

void CodeEditor::test()
{
highlightCurrentLine(); //function based on CodeEditor example
highlightCurrentWord("bar");
}

void CodeEditor::highlightCurrentWord(QString curWord)
{
QTextCharFormat fmt;
fmt.setBackground(Qt::red);
fmt.setForeground(Qt::black);
//...
QTextCursor cursor = QTextCursor(block);
cursor.select(QTextCursor::WordUnderCursor);
//...
cursor.setPosition(begin, QTextCursor::MoveAnchor);
cursor.setPosition(end, QTextCursor::KeepAnchor);
cursor.mergeCharFormat(fmt); //I did try also cursor.setCharFormat(fmt);
//...

To copy to clipboard, switch view to plain text mode 

So for example if I have three lines

foo xyz bar

bar edddd

abc bar

let's say line 1 is cursor current line and therefore is highlighted. I want to highlight 'bar' word it will be highlighted in lines 2, 3 but not in line 1 cause of line highlight present.

Anyone know how to solve this issue ? somehow merge formating ?

Thanks in advance!
