You can probably do it trough javascript as well.
For instance, I have a Piece.qml that acts as kind of "class header" to
create instances of Piece qml objects.
From javascript I the do:
var component = Qt.createComponent("Piece.qml");
pieces.push(component.createObject(gameBoard, {"x": xpos, "y": ypos,
"width": pw, "height": pw}
to setup a gaming board.
To connect the signals, at the end of Piece.qml I have something like:
Component.onCompleted: {
mouse.swipe.connect(Ui.movePlayer)
Where mouse.swipe is a signal I created for MouseArea {id: mouse ...} and
where Ui is my javascript, movePlayer being a function in there.
Then to clear the board and remove the objects from screen I do:
for (var i in pieces)
pieces[i].destroy()
So to lookup in docs is Qt.createComponent, createObject, connect, destroy.
quickhit example is QtSDK is a full example to play around with.
Hope this helps a bit,
Harri
