SetContextProperty and threading

SavageTwinky

I'm having a small issue with creating an object on a thread as well as setting it as a property in a qml view. I'm just wondering why this doesn't work. I want the qml view to update while the work is being done but it does not.

main .cpp
@
// create update thread
QThread sexyThread;
Sexy sexyWork;
sexyWork.moveToThread(&sexyThread);
updateThread.start();

// create view
QDeclarativeView view;
// hook up the update class to the view
view.rootContext()->setContextProperty("sexyView", &sexyWork);

// set the main view
view.setSource(QUrl("qrc:QML/main.qml"));

#ifdef TARGET
view.showFullScreen();
#else
view.show();
#endif
return app->exec();
@

main.qml
@
import Qt 4.7

Rectangle {
width: 800; height: 480

Connections {
    target: sexyView
}

Text {
    id: statusText
    x: 327
    y: 91
    text: sexyView.getStatusToQML
    anchors.topMargin: 91
    anchors.top: parent.top
}

ProgressBar {
    id: progress
    x: 275
    y: 139
    value: sexyView.getProgressToQML
}

Button {
    anchors.centerIn: parent
    onClicked: sexyView.runUpdate(&#41;
}

}

Hi,

Did you check that the property name you are using in setContextProperty is the same as the one you have in your QML ? Here for example "sexyView" and you are giving it your worker object.

Posting your QML code would also help

Yah everything works fine, it's just I don't get the gui updates until the very end sorry for not clarifying that.

i'm guessing I can't tie a threaded object directly as a context property? i'll just find another way to do this
