[solved]QImage Load issue

[kamlmish]

Hi
I have a small piece of code to load a list of images

void MainWindow::listdisplay()
{
    QDir dir("/home/kamlesh/Gall/GALL/images/eBeam Gallery/Art & Design/2D Shapes");
    dir.setFilter(QDir::Files);
    QList<QImage> images;
    QImage thumb, tmp;
    int sizeW = 20;
    int sizeH = 20;
    QStringList listfiles = dir.entryList(QStringList()<<"*.png",QDir::Files);
    for(int i=0;i<=listfiles.count();i++)
    {
 
       [B] QString filename = listfiles.at(i);
        bool x = tmp.load(filename);[/B]
        //bool x = tmp.load("/home/kamlesh/Gall/GALL/images/eBeam Gallery/Art & Design/2D Shapes/Black Hexagon.png");
        if(x == true){
        thumb = (tmp.scaled( 1240, 1480 ).scaled( sizeW, sizeH, Qt::KeepAspectRatio )); //two passes
        modl->setData( modl->index( i, 0 ), thumb, Qt::DecorationRole );}
    }
    //listwidget->addItems(listfiles);
    viw->setModel(modl);
    viw->show();
 
}

void MainWindow::listdisplay()
{
    QDir dir("/home/kamlesh/Gall/GALL/images/eBeam Gallery/Art & Design/2D Shapes");
    dir.setFilter(QDir::Files);
    QList<QImage> images;
    QImage thumb, tmp;
    int sizeW = 20;
    int sizeH = 20;
    QStringList listfiles = dir.entryList(QStringList()<<"*.png",QDir::Files);
    for(int i=0;i<=listfiles.count();i++)
    {

       [B] QString filename = listfiles.at(i);
        bool x = tmp.load(filename);[/B]
        //bool x = tmp.load("/home/kamlesh/Gall/GALL/images/eBeam Gallery/Art & Design/2D Shapes/Black Hexagon.png");
        if(x == true){
        thumb = (tmp.scaled( 1240, 1480 ).scaled( sizeW, sizeH, Qt::KeepAspectRatio )); //two passes
        modl->setData( modl->index( i, 0 ), thumb, Qt::DecorationRole );}
    }
    //listwidget->addItems(listfiles);
    viw->setModel(modl);
    viw->show();

}

Issue is that , I am able to get the filename , but when I use
QImage::load(filename)
it returns FALSE value

have you debuged the content of filename? I guess it is only relative to dir. So you probably have to prepend that first.

Even after appending the full path, QImage::Load doesnt work

void MainWindow::listdisplay()
{
    QDir dir("/home/kamlesh/Gall/GALL/images/eBeam Gallery/Art & Design/2D Shapes");
    dir.setFilter(QDir::Files);
    QList<QImage> images;
    QImage thumb, tmp;
    int sizeW = 20;
    int sizeH = 20;
    QStringList listfiles = dir.entryList(QStringList()<<"*.png",QDir::Files);
    for(int i=0;i<=listfiles.count();i++)
    {
        QString filename = listfiles.at(i);
        QString filepath = dir.absoluteFilePath(filename);
        bool x = tmp.load(filepath);
        //bool x = tmp.load("/home/kamlesh/Gall/GALL/images/eBeam Gallery/Art & Design/2D Shapes/Black Hexagon.png");
        if(x == true)
        {
        thumb = (tmp.scaled( 1240, 1480 ).scaled( sizeW, sizeH, Qt::KeepAspectRatio )); //two passes
        modl->setData( modl->index( i, 0 ), thumb, Qt::DecorationRole );
        }
 
    }

void MainWindow::listdisplay()
{
    QDir dir("/home/kamlesh/Gall/GALL/images/eBeam Gallery/Art & Design/2D Shapes");
    dir.setFilter(QDir::Files);
    QList<QImage> images;
    QImage thumb, tmp;
    int sizeW = 20;
    int sizeH = 20;
    QStringList listfiles = dir.entryList(QStringList()<<"*.png",QDir::Files);
    for(int i=0;i<=listfiles.count();i++)
    {
        QString filename = listfiles.at(i);
        QString filepath = dir.absoluteFilePath(filename);
        bool x = tmp.load(filepath);
        //bool x = tmp.load("/home/kamlesh/Gall/GALL/images/eBeam Gallery/Art & Design/2D Shapes/Black Hexagon.png");
        if(x == true)
        {
        thumb = (tmp.scaled( 1240, 1480 ).scaled( sizeW, sizeH, Qt::KeepAspectRatio )); //two passes
        modl->setData( modl->index( i, 0 ), thumb, Qt::DecorationRole );
        }

    }

The images have been taken from MACOS, and the work environment is linux,qt
Is that the issue ?

try use an easy directory instead of "/home/kamlesh/Gall/GALL/images/eBeam Gallery/Art & Design/2D Shapes/", such as "/tmp/1.png"
hope to help you.
