Can we declare global variable in QML file?

Question

I want to do something similer to following code:

//test.qml import QtQuick 1.0 Item  {     var globalforJs =10;      function increment() // JavaScript function     {         globalforJs++;     }     .... QML Code 

Can we have global variable in QML file and access it from the JavaScript function?

Answer 1

Try property int globalForJs: 10;

If you want a variable that can take any type:

property var globalForJs: 10

Prior to QML 2, use the variant keyword instead of var.

Answer 2

Using int or variant properties do not create a javascript variable, but rather a semantically different generic QML property (see here)

Before Qt 5, global javascript variables were recommended to be defined in a separately imported javascript file, however Qt 5 adds a var type property support.
