How to display image in directory?

sanda199

Hi I am quite new to qt. I wrote a program which display image in label. But at first I put image in build folder of my program. It can display fine. But when I move my image to home folder, it cannot display. My image is at Home folder. I am using ubuntu 11.10. my program is like that
@
#include <QtGui/QApplication>
#include "mainwindow.h"
#include <QLabel>

int main(int argc, char *argv[])
{
QApplication a(argc, argv);
QImage myImage;
myImage.load(":/Home/1.jpeg");

QLabel myLabel;
myLabel.setPixmap(QPixmap::fromImage(myImage));

myLabel.show();


return a.exec(&#41;;

}
@

If anything wrong, pls kindly tell me. Thanks.

Edit: please enclose code snippets in @ tags; Andre

to

@myImage.load(”/home/1.jpeg”);@

Sorry i was wrong.
In ubuntu as i know home path is /home/username/
So check the real path of file, it must be something like /home/username/1.jpeg

Hello

I know this was solved, but you could avoid future problems with images when using "Qt's resources mechanism":http://qt-project.org/doc/qt-4.8/resources.html.

bq. The Qt resource system is a platform-independent mechanism for storing binary files in the application's executable. This is useful if your application always needs a certain set of files (icons, translation files, etc.) and you don't want to run the risk of losing the files.

Hope this helps a little bit more and takes you one step further :)
