how can I find number of lines in QTextedit ?

[redkite]

Hi, Jpn nearly give you the answer, I suggest you to find a tutorial on how using the Qt4 Assistant.

I'm in a good moon, I will explain you.

QTextDocument * QTextEdit::document () const

QTextDocument * QTextEdit::document () const

To copy to clipboard, switch view to plain text mode 

As you can see, this method return a QTextDocument* and as jpn said in his first reply, this class have the property you are looking for :

blockCount : const int

blockCount : const int

To copy to clipboard, switch view to plain text mode 

Finishing with a little example (very little) :

...
QTextEdit *textEdit;
int i = textEdit->document()->blockCount();
...

...
QTextEdit *textEdit;
int i = textEdit->document()->blockCount();
...

To copy to clipboard, switch view to plain text mode 

and i will contain the number of lines that textEdit contain. (more exactly the number of return, I mean an empty line is also counted)

Hope this will be enough ^^ and hope you will give more importance to the doc !!

Cheers.

I think these are called paragraphs Of course excluding empty blocks unless you treat them as empty paragraphs...
