Hi,
i am porting the UI of my cacheme application to qml. Most things somehow work,
some even nicely (making map overlays
is a snap) and some are rather tricky (a nice file selector). But there is one
thing i can't figure out how to do correctly:
I have a widget which is a ggraphicsgeomap. This widget of course needs to
interface to various things like the
gps. My original plain qt had a global instance of my locationProvider class
and i connected this to a slot in my mapwidget instance.
But how do i do that with qml in between? My main.cpp contains an instance of
my locationProvider, so i need a connect
my custom widget with the instance only known to my main function. I think one
step is to register my locationProvider with the
declarative view:
LocationProvider locationProvider;
view.rootContext()->setContextProperty("LocationProvider", &locationProvider);
in my qml part i create an instance of my map class (my map is registered in
c++ via
qmlRegisterType<MapWidget>("MapWidget", 1, 0, "Map"), so the widget is created
this way:
Map {
id: map
}
Now the question: How do i connect a signal from my locationProvider with a
slot of my map?
Regards,
Till
