Dear Everyone,
How can we display a jpg file in a widget.
I m using following code but there is no output .....

QLabel *imageLabel;
imageLabel = new QLabel(this,0);
imageLabel->setGeometry ( locx,locy,w,h );
imageLabel->setBackgroundRole(QPalette::Base);
imageLabel->setSizePolicy(QSizePolicy::Ignored, QSizePolicy::Ignored);
imageLabel->setScaledContents(true);
QImage image(mediaPath[currentIndex]);
if (!image.isNull())
{
qDebug()<<"Image"<<mediaPath[currentIndex];
}
imageLabel->setPixmap(QPixmap::fromImage(image));

Please if you have any idea about it give reply.
Thanks:

Do you have the QJPEG plugin? What does QImageReader::supportedImageFormats() return?

P.S. Please, don't double-post.

Hello Everyone,
I m displaying a .jpg file in a widget through QLabel and QScrollerArea Class .
But it does not display the .jpg files

My coding is as following ..........

Qt Code:

Switch view

QLabel *imageLabel;
	imageLabel = new QLabel;
	imageLabel->setBackgroundRole(QPalette::Base);
	imageLabel->setSizePolicy(QSizePolicy::Ignored, QSizePolicy::Fixed);
     	imageLabel->setScaledContents(TRUE);
 
 QImage image(mediaPath[currentIndex]);
	imageLabel->setPixmap(QPixmap::fromImage(image));
	imageLabel->resize(imageLabel->pixmap()->size());
scrollArea->setBackgroundRole(QPalette::Dark);
	scrollArea->setWidget(imageLabel);
	scrollArea->setWidgetResizable(TRUE);

QLabel *imageLabel;
	imageLabel = new QLabel;
	imageLabel->setBackgroundRole(QPalette::Base);
	imageLabel->setSizePolicy(QSizePolicy::Ignored, QSizePolicy::Fixed);
     	imageLabel->setScaledContents(TRUE);

 QImage image(mediaPath[currentIndex]);
	imageLabel->setPixmap(QPixmap::fromImage(image));
	imageLabel->resize(imageLabel->pixmap()->size());
scrollArea->setBackgroundRole(QPalette::Dark);
	scrollArea->setWidget(imageLabel);
	scrollArea->setWidgetResizable(TRUE);

To copy to clipboard, switch view to plain text mode

If anyone has any idea please reply it.
Thanks in advance......................
