Highlighting the running line in QTextEdit
Message 1 in thread
Hello
There is a program running in a QTextEdit, and I know the line number(int
currentLine).Does any knows how to highlighting the running line?
I do it this way, but it's doesn't work well(Just move down a few lines,
then stops there.But the program has not came to the end yet, that is, the
program is still exected.)
void Neopen::Highlighting(int currentLine)
{
QTextCursor cursor = programTextEdit->textCursor();
cursor.setPosition(line, QTextCursor::KeepAnchor);
cursor.select(QTextCursor::LineUnderCursor);
programTextEdit->setTextCursor(cursor);
}

Waiting 5 hours, after posting at a time when many are asleep (1:30 am local for me) or are just waking up, and then sending out a “Any ideas response” is just downright rude.
I highly suggest you read through the QT documentation… look at the “all classes” page and look for the work highlight…

(Grin) *rude* isn't the word to describe this. *Pushy and lazy to read Docs*

Desperate, more likely. The docs don't help much in cases like this.

You probably need to either call programTextEdit->repaint(), or
QApplication::ProcessEvents() to allow the repaint to update the screen.
