Communication between two qml files

Hannah24

Hello, I think this question might be really silly but since am just a few days old in qml. I would like to clarify my silly queries afterall you learn from mistakes.
I have two qml files. I want the mainfile to communicate wih the other file. Simple example:
main.qml:
@Rectangle {
width: 360
height: 360
MouseArea {
anchors.fill: parent
onClicked: {
secondwindow.visible=true
}
}
}
@

sub.qml

@Rectangle {
id:secondwindow
width: 100
height: 62
color:"REd"
visible:false
}
@

Onclick event it should display secondwindow which is in another qml file. This is my basic doubt if this is cleared I can proceed further.Thank you in advance.

For a component to be recognised by QML engine, the "sub.qml" needs to begin with a capital letter ("Sub.qml"). Then you can add it as a component to your main.qml like this:
@
Sub {
id: secondwindow
}
@

And now your code should work. Just remember to position the Sub component properly (by anchoring or setting x, y, width, height manually).

john ankanna please put the source code between '@' tags for better readability. Also, please don't hijack other people's threads.

What error are you getting? I have never coded using Cascades, but maybe your problem lies in QtQml or QtQuick, in which case I might be able to help.

You cannot mix BlackBerry Cascade with Qt Quick.You either create Cascade project or Qt Quick project.
