The “get_db()” function is a member function of the implicit type defined by your top QML file. To invoke it you need to resolve it on a reference of the instance. There are a few ways you can get access to a reference of the instance: either directly by id (if it’s in the same component scope), passing a reference to the object as a parameter of a function, storing a reference in a pragma library JavaScript resource, and so on. An example of the latter is included.
eg:
// shared.js
.pragma library
var databaseObject = null
function init(dbObj) {
databaseObject = dbObj;
}
// DatabaseAccess.qml
import QtQuick 2.0
import QtQuick.LocalStorage 2.0
import "shared.js" as Shared
Text {
id: root
....
function get_db() {
....
}
Component.onCompleted: Shared.init(root)
}
// OtherFile.qml
import QtQuick 2.0
import "shared.js" as Shared
Item {
Component.onCompleted: {
Shared.databaseObject.get_db(); // etc.
}
}
I’d suggest reading the documentation about attributes of objects (which includes properties, methods, the id, and so on) for more information about this stuff.
Cheers,
Chris.
