How to scale pixmap to fit

Hi this is the code i currently have:

Code:

---

ui->imagebox->setPixmap(QPixmap("C:\\Picture2.png"))

---

where imagebox is a label.

How do i scale this to fit the label it is contained within?

Thanks for your time and trouble.

Have a look at the QPixmap doc:

Quote:

---

QPixmap scaledToHeight ( int height, Qt::TransformationMode mode = Qt::FastTransformation ) const
QPixmap scaledToWidth ( int width, Qt::TransformationMode mode = Qt::FastTransformation ) const

---

I think you are looking for:

Code:

---

ui->imagebox->setScaledContents(true);

Thanks Joh, your solution worked great.

is great, however I need to scale the content of the label background picture just to the width (I've got always wider, then higher pictures and I do not want to make images to be deformed).
I've tried:

Code:

---

void SetImage( QLabel * pLabel, QImage * pImg )
{
        pLabel->setBackgroundRole( QPalette::Base );
	pLabel->setSizePolicy( QSizePolicy::Ignored, QSizePolicy::Ignored );
 
	pLabel->setAlignment( Qt::AlignHCenter | Qt::AlignVCenter );
 
	QPixmap qPixMap = QPixmap::fromImage( * pImg );
	qPixMap.scaledToWidth( 400 );  // width of the label
	pLabel->setPixmap( qPixMap );
}

---

but it doesn't work.

Can anybody suggest me how to do that.
I'll be grateful for an explanation, why the code above doesn't work.

Thank you a lot.

you didn't explain what "doesn't work" mean.
But I can prity much guess.
The docs for this method says:

Quote:

---

Returns a scaled copy of the image.

So it does not alter the object calling the method, but RETURNS the result.
So you need to do something like:

Code:

---

qPixMap = qPixMap.scaledToWidth( 400 );  // width of the label
