How to display a picture

[Payx]

I found what i sought :

QStringList fileNames = QFileDialog::getOpenFileNames(this, tr("Open Image"),"/path",tr("Image Files (*.jpg)"));

But i got all files, and i just want .jpg for now """"""tr("Image Files (*.jpg)"));"""""""""" dont work ?

then i want to put my picture file in a label, but i can't find how to convert a QStringList to a Qimage or Qpixmap

@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*)"

@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.
