Qt import library - creating a QML function

[teh_raab]

Hi All,

Im probably being really dumb and staring right at the issue but can't see the solution.. I've written an import library that we use for various Qt 4.8 QML applications. I have various objects that i can instantiate inside QML without any problem e.g.

Logger {
	id: write;
	name: "Main.qml";
	Component.onCompleted: {
		log("log started");
	}
}

Logger {
	id: write;
	name: "Main.qml";
	Component.onCompleted: {
		log("log started");
	}
}

To copy to clipboard, switch view to plain text mode 

and as expected, have access to this "Logger" components "log" method e.g.

MouseArea {
	anchors.fill: parent;
	onClicked: {
		write.log("Mouse area clicked)
		console.log(convert.time_ms_to_sec(-1));
		console.log(convert.time_ms_to_sec(15000));
	}
}

MouseArea {
	anchors.fill: parent;
	onClicked: {
		write.log("Mouse area clicked)
		console.log(convert.time_ms_to_sec(-1));
		console.log(convert.time_ms_to_sec(15000));
	}
}

To copy to clipboard, switch view to plain text mode 

This all works fine. My problem is that i now want to create some global functions inside my import library that can be called from anywhere without having to instantiate an object in every QML file. For example, i made a test function that converts milliseconds to seconds, but in order to use it i have to declare my "Conversion" object in each QML file, like..

Conversion {
	id: convert;
}
 
MouseArea {
	anchors.fill: parent;
	onClicked: {
		console.log(convert.time_ms_to_sec(15000));
	}
}

Conversion {
	id: convert;
}

MouseArea {
	anchors.fill: parent;
	onClicked: {
		console.log(convert.time_ms_to_sec(15000));
	}
}

To copy to clipboard, switch view to plain text mode 

Is there a way of doing this without having to declare the "Conversion {}"?!? I want to be able to simply call convert.time_ms_to_sec(<val>) in any script that has my import.

Thanks in advanced,

Raab.
