"var"

[september]

on the type of var gives this error "
(qrc:/tank/tank1.qml:10:14: Expected property type)
QDeclarativeComponent: Component is not ready
QGraphicsScene::addItem: cannot add null item"

[JKSH]

"Component is not ready" suggests that it takes time for your component to load. You need to wait until it finishes loading, before assigning it to a variable.

Do the assignment inside the Component.onCompleted() signal handler. See:

• http://qt-project.org/doc/qt-5/qml-qtqml-component.html#onCompleted-signal
• http://qt-project.org/doc/qt-5/qml-var.html#change-notification-semantics

The 'var' property type is only available in QtQuick 2.0, not in QtQuick 1.0. (Well, technically, in QtQml 2.0, but yeah.)

Cheers,

september, are you able to upgrade to Qt Quick 2? Qt Quick 1 is obsolete now.
