Scaling QPixmap to fit Label

[gabor53]

The following code is working, but the image is not scaled to fit the label.

#include "dialog.h"
#include "ui_dialog.h"

Dialog::Dialog(QWidget *parent) :
    QDialog(parent),
    ui(new Ui::Dialog)
{
    ui->setupUi(this);

    QPixmap pix("C:/Programming/Qtsamples/Image_handling/IMG_6745.jpg");
    ui->label->setPixmap (pix);
}

Dialog::~Dialog()
{
    delete ui;
}

```'
How to make the image fit inside the label? (I tried several suggestions from the internet but they didn't work.)
Thank you for your help.

Hi,
setting scaledContents of the label should do it.

ui->label->setScaledContents(true);

You can also do

QPixmap p; // load pixmap
// get label dimensions
int w = label->width();
int h = label->height();
// set a scaled pixmap to a w x h window keeping its aspect ratio 
label->setPixmap(p.scaled(w,h,Qt::KeepAspectRatio);

If you need to scale it down to fit the are of the label.

Thank you. Both worked though I guess it is supposed to be

int w = ui->label->width ();
int h = ui->label->height ();
ui->label->setPixmap (pix.scaled (w,h,Qt::KeepAspectRatio));
