I wrote the following code to assign image source runtime .
//main.h
class Main : public QQuickView
{
Q_OBJECT
public:
static Main *instance();
void mousePressEvent(QMouseEvent* m);
//void keyReleaseEvent(QKeyEvent* e);
void setup();
static QObject *rootObject;
static QObject *image;
int lock_value;
static QStringList lockimage;
private:
explicit Main();
};
//main.cpp
main instance ()
{
QDeclarativeView* view = NULL;
view->setSource(QUrl::fromLocalFile(“main.qml”));
rootObject = dynamic_cast<QObject *>(view->rootObject());
//rootObject = (QObject *)view->rootObject();
// find element by name
image = rootObject->findChild<QObject *>(QString(“status_locked_img”));
}
display instance ()
{
image->setProperty(“source”, QString(“images/image1.png”));
}
//main.qml
Rectangle {
id:status_locked
color: “black”
width: 10; height:10
x:8;y:6
property int type : lock_status
Image {
objectName: status_locked_img
visible: true
}
I am getting error while building
“ error: C2681: ‘QGraphicsObject *’ : invalid expression type for dynamic_cast”
please help me in resolving this error
