QTextEdit

Hello friends,

I am implementing a header and footer in my application...

I an using QTextEdit for header and footer....

Now My problem is..

How do i disable the scrollbar which will automatically appears as the data
in the TextEdit increases,

I want the TextEdit to resize itself as the content increases...

In Qt3 we had heightForWidth function to do this ....

How can I achieve the same in Qt4..

Thanks

Use:

Code:

---

textEdit->setHorizontalScrollBarPolicy(Qt::ScrollBarAlwaysOff);
textEdit->setVerticalScrollBarPolicy(Qt::ScrollBarAlwaysOff);

---

Regards

I am able to remove the scrollBar now,
But How to resize the TextEdit based on the content of the edit...

what is the equivalent functionality of heightForWidth

Code:

---

QTextEdit *text = new QTextEdit(window);
	text->resize(640, 30);
        text->setVerticalScrollBarPolicy(Qt::ScrollBarAlwaysOff); 
	qDebug() << "before " <<text->width();
	text->setText("AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAABBBB
        BBBBBBBBBBBBBBBBBBBBBBBBCCCCCCCCCCCCCCCCCCCCRRRRRRRRRRRRRR
        RRRRRRRRRRRRRRRRRRGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGG
        GGGGGGGGGGGGGGGGGGGGGGGGGJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJ
        JJJJKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKK");
	qDebug() << "After " <<text->width();
	int ht = text->heightForWidth(text->width());
	if(ht > 20)
	text->resize(text->width(), ht);

---

In the above code the width and height remain the same before and after the text is inserted....

How could I resize the TextEdit based on content .

And How can I get the total number of lines in TextEdit.

Thanks

If you want a widget that can display rich text and resizes it self to the contents of the text, how about using QLabel instead of QTextEdit?
