QQuickImageProvider not recieving Unicode from Qml - cannot find image

T_Eng

Hi,
I am building an application with a QML image source that is set from C++ backend. My problem being the QQuickImageProvider I have attached to my application engine as an image provider takes in the image source data as a QString in the requestPixmap function - using the example provided in QQuickImageProvider doc

class ColorImageProvider : public QQuickImageProvider
{
public:
    ColorImageProvider()
        : QQuickImageProvider(QQuickImageProvider::Pixmap)
    {
    }

    QPixmap requestPixmap(const QString &id, QSize *size, const QSize &requestedSize)
    {
        int width = 100;
        int height = 50;

        if (size)
            *size = QSize(width, height);
        QPixmap pixmap(requestedSize.width() > 0 ? requestedSize.width() : width,
                       requestedSize.height() > 0 ? requestedSize.height() : height);
        pixmap.fill(QColor(id).rgba());

        return pixmap;
    }
};

How can I ensure the Unicode string properly propagates from C++ backend to QML back to QQuickImageProvider::requestPixmap()?

Thanks!

Hi,

Can you show how you are using your provider in your code ? As well as an example of string ?
