How to display a picture

mrjj

@Payx
it should work with *.jpg.

but i can't find how to convert a QStringList to a Qimage or Qpixmap

Oh just use
fileName = QFileDialog::getOpenFileName(this,
tr("Open Image"), "/", tr("Image Files (*.png *.jpg *.bmp)"));

It only returns the 1 filename. ( NOTE THE MISSING s)

ui->mylabel->setPixmap( new QPixmap(fileName ));

Payx

I got one error : Expected one specifier before pixmap

mrjj

@Payx
the class is QPixmap
so its "new QPixmap"

~~setPixmap( new QPixmap(fileName ));~~

Sorry, was just fast code.

Payx

Yes i tried too before post but i had one error too, so i post the first error.

The second is :
No matching function for call to 'Qlabel::setPixmap(QPixmap*)"

mrjj

@Payx
Sorry not enough coffee :)

QPixmap pix(fileName );
setPixmap(pix);

If u are using QImage

m_imageLabel = new QLabel;
QImage imagePixmap;
imagePixmap.load(":/new/prefix1/Images/imageName.extension");
m_imageLabel->setPixmap(QPixmap::fromImage(imagePixmap));

Or

Only QPixmap

m_imageLabel = new QLabel;
QPixmap imagePixmap;
imagePixmap.load(":/new/prefix1/Images/imageName.extension");
m_imageLabel->setPixmap(imagePixmap);

imageName.extension can be image.png, image.jpeg.
