[SOLVED]Dynamically Created Custom QML Type has no Children

fatdollar

I've written a custom QML Type in c++ which is a Vehicle Gauge. The class works wonderfully and I can export it to QML and use it just fine. I then created a QML file with this custom type as the Parent/Root item in the file. If I load this QML file in start up everything works as desired. My custom signals work as I expect them to. The other objects (ie MouseArea, Rectangle) behave just fine.

The problem comes when I try to dynamically create this QML file. None of the objects know anything about the other ones in the file and my signals form the custom QML type don't fire. I know they are getting sent but the QML doesn't do anything. The object loads and shows up in the view but dosn't do anything.

Here is some Code to demonstrate a little bit:

C++:
@class MyGauge: public QQuickPaintedItem
{
Q_OBJECT

//QML properties
//various properties

......

signals:
void mySignal();
......
// functions and such
}
@

QML file using MyGauge:
@MyGauge{
id: gauge
onMySignal: {
console.log("on move gauge")
mouse.function()
}

Rectangle {
    id: highlight
    anchors.fill: parent
    color: "transparent"
    border.color: "black"
    border.width: 3
    visible: mouse.visible
}

MouseArea {
    id: mouse
    anchors.fill: parent
    visible: false
    onReleased: {
        console.log("release")
        gauge.z = 0//bottom level
        drag.target = null
        visible = false
        exitMenu()
    }

    function function() {
        visible = true
        drag.target = gauge
        drag.axis = Drag.XandYAxis
        drag.maximumX = gauge.parent.width - gauge.width
        drag.minimumX = 0
        drag.maximumY = gauge.parent.height - gauge.height
        drag.minimumY = 0
        gauge.z = 31//on top of all gauges
    }
}

function function1(col,row) {
   //calculatoins
}

function function2(x,y,mX,mY) {
   //calculations
}

}

javascript for creating MyGauge:

As I said before the QML file works perfectly when it is not used with the javascript to dynamically create the object. But when I use the javascript to create the object onMySignal doesn't even process. I can manually connect the signal to a function using :
@gauge.onMoveGauge.connect(foo)@

However then I can't call function1 or function2 anywhere in the file because I get then error that they are undefined. The highlight.visible also does not update with the mouse.visible even if I use a Binding element. Also when i try to look at the children of gauge i get null...as if the MouseArea and Rectangle aren't event there.

I'm completely at a loss as to what is happening...at this point any advice would be better than my frustrated attempts to hack this apart.

OK I ended up solving this one on my own...

The problem was where is was calling the javascript function createGauge.

Basically I had a Parent object that dynamically created a menu for the gauge selection...I called my create function within the menu and it did not work.

When I create MyGauge from within the parent object it worked just fine.

Thanks. I hope that made sense...if you have any questions of that didn't make any sense I'd be happy to clarify.
