Hello,
I am still stuck with the traversal.
Well I have simple example pageloader.qml, a.qml and b.qml and i would like to
display other qml file when mouse is clicked on the text.I tried Loader {source
:"a.qml"} and I tried to use "source : "b.qml"" onClicked of a.qml it didn't
work as source is not in the scope.,couldn't achieve desired result.
//Pageloader.qml
import Qt 4.7
Item {
width: 200
height: 200
a {opacity: 1} ---->>>>> cannot assign to non-existent property "a"
b {opacity: 0}
}
//a.qml
import Qt 4.7
Rectangle {
id: rectangleA
width: 200
height: 200
Text {
x: 72
y: 67
width: 28
height: 48
text: "A"
font.bold: true
font.pointSize: 30
anchors.horizontalCenter: parent.horizontalCenter
anchors.verticalCenter: parent.verticalCenter
MouseArea{
anchors.bottomMargin: 0
anchors.topMargin: 0
anchors.leftMargin: 0
anchors.rightMargin: 0
anchors.fill: parent
onClicked:{
console.log("A Clicked!")
}
}
}
}
//b.qml
import Qt 4.7
Rectangle {
id: rectangleB
width: 200
height: 200
Text {
x: 72
y: 67
width: 28
height: 48
text: "B"
font.bold: true
font.pointSize: 30
anchors.horizontalCenter: parent.horizontalCenter
anchors.verticalCenter: parent.verticalCenter
MouseArea{
anchors.bottomMargin: 0
anchors.topMargin: 0
anchors.leftMargin: 0
anchors.rightMargin: 0
anchors.fill: parent
onClicked:{
console.log("B Clicked!")
}
}
}
}
The documentation @
http://doc.trolltech.com/4.7-snapshot/qdeclarativescope.html says:
"The component instance scope hierarchy extends to out-of-line components, too.
In the following example, the TitlePage.qml component creates two TitleText
instances. Even though the TitleText element is in a separate file, it still
has access to the title property when it is used from within the TitlePage.
QML is a dynamically scoped language - depending on where it is used, the title
property may resolve differently."
Could someone explain how the above statement conflicts with above my test
example?
Thanks and regards,
Rakesh

Either load both and transition visually:
Item {
A { opacity: 0 }
B { opacity: 1 }
... logic to change opacities ...
}
Or use Loader to load just one at a time (really only necessary if A and B are
quite large and complicated).
