Please share more information about the errors by showing the build issues and the compile output.

Resource files are the way to go. If you have issues with files that are not found, you are not setting your paths correctly.

Emily

my error is qrc:/qml/qmlevolution/PicturePathviewDelegate.qml:19:9: QML Image: Cannot open: qrc:/home/user/MyDocs/DCIM/png/320_50633_fe167344f5c3eb3.png

my picture path is /home/user/MyDocs/DCIM/png

the picture displaied normal when there is no resource file

andre

You mean that inside your resource file, you use the /home/user/MyDocs/DCIM/png/ path?! That path looks suspiciously like a local file path.

Personally, I'd just use something like images/ as the path in my qrc.

Could you show us the contents of your .qrc file please?

Emily

my icon of png can display but the picture_viewer application executable can't display nesssary pictures in /home/user/MyDocs/DICM/png

The problem is quite obvious then, I think:

You are trying to load an image file with the :/home/user/MyDocs/DCIM/png/320_50633_fe167344f5c3eb3.png path, but that path does not exist in your resource.

You should use relative paths in your qml files. That prevents issues like these. On top of that, I would suggest you group your files properly. That is: you put images in a separate directory. That is just a style issue though.

Emily

I don.t want :/home/user/MyDocs/DCIM/png/320_50633_fe167344f5c3eb3.png as icon
Though I don't add the directory in resource file ,the error is the directory automaticly added qrc
I use QDir to load and scan /home/user/MyDocs/DCIM/png/
the code as fellow

@
m_pictureFolder = new PictureFolder("/home/user/MyDocs/DCIM/png");

PictureFolder::PictureFolder(const QString workDir)
{
m_qListPicture = new QList<Picture>;
QStringList filters;
foreach(QByteArray format, QImageReader::supportedImageFormats())
filters += "." + format;
imageScan(workDir,filters/,out*/);
}

void PictureFolder::imageScan(const QString &path,const QStringList &filters/, QTextStream &out/)
{
QDir pictureDir(path);

foreach(QString file, pictureDir.entryList(filters,QDir::Files))
{
    file=pictureDir.absoluteFilePath(file);
    *m_qListPicture << Picture(file,"comments here:");/*生成了一个图片对象*/

}

foreach(QString subDir, pictureDir.entryList(QDir::Dirs|QDir::NoDotAndDotDot))
    imageScan(path + QDir::separator() + subDir, filters/*,out*/);

}
