[solved] QML increasing memory usage

SteveKing

I've been trying to use a loader to load different QML 'pages' in my application and have found that eventually it runs out of memory. From running this through a memory analyzer it seems that the number of QScriptObject::Data and QScript::QVariantDelegate seem to keep increasing. The simple code is shown at the bottom.

You'll see from this that I've also tried using a page / page stack from the QML components, but this uses memory even faster!

@Rectangle {
id: mainItem
anchors.fill: parent

Timer {
   running: true
   interval: 500
   repeat: true
   property bool p1: true
   onTriggered: {
      if (p1)
      {
         console.log("A")
         p1 = false
         //localPageStack.push(page2)
         pageShow.sourceComponent = page2
      }
      else
      {
         console.log("B")
         p1 = true
         //localPageStack.pop()
         pageShow.sourceComponent = page1
      }
   }
}

Component {
   id: page1
   // Page {
   Rectangle {
      anchors.fill: parent
      Rectangle {
         anchors.fill: parent
         color: 'white'
         Text {
            text: "Hello"
         }
      }
   }
}
Component {
   id: page2
   //Page {
   Rectangle {
      anchors.fill: parent
      Rectangle {
         anchors.fill: parent
         color: 'white'
         Text {
            text: "Goodbye"
         }
      }
   }
}

Loader {
   id: pageShow
   anchors.fill: parent
   sourceComponent: page1
}

//Component.onCompleted: localPageStack.push(page1)

//screen area
//PageStack {
//  id: localPageStack
//  anchors.fill: parent
//}

}

Looks like the function @gc()@ works for the loader case...
