accept from url, and with argument

[mateosalta]

if a app wanted to link to webapp creator - ubports/morph-browser#18
we would need to accept a url argument

You can do it by adding webapp-creator.url-dispatcher file with the contents: [{"protocol": "webapp-creator"}] and adding a hook to manifest.json file: "hooks": { "webapp-creator": {"urls": "webapp-creator.url-dispatcher"} }.
Then you can invoke Webapp Creator by URL: webapp-creator://params and get the params by parsing the URL in QML: var params = Array.prototype.slice.call(Qt.application.arguments).filter(function (a) { return a.match(/^webapp-creator:\/\//); })[0].substring(17);
The image in QML could be serialized as data URI: Image { source: "data:image/png;base64," + imageDataFromURL }.
