Hello,
I am formatting a very long text in QTextArea, because of the size of the text my application is very slow,
so I am trying to format only the text that is about to be viewed by the user, but I don't know how to get only that part of the text
for example:
.
.
.
this is a very long text
this is a very long text
this is a very long text

this is a very long text
this is a very long text
.
.
.
Is it possible to get the range of text lines that will be rendered by QTextEdit?
I am using
ui->textEdit->verticalScrollBar()
but I don't know how to convert its current position to line number, I am just a beginner at QT programming.
Thank you.
Regards.
