Hello together,
can anyone here help me with the second Hand in Watchface?
I´m trying to program an Watchface with an sweeping seond Hand. As Basic I used the example Code in Visual Studio. Here the Watchdace get the Time by using the OnTick Mothode in the Main Class. The Rotation will be set in an Class called ClockViewModel. Here my Question: How can I manage that the watchface get the time permanently, so I can use the millisendos for calculating the rotationangle, not only once a second by using the TimeTick Event?
Perhabs someone of you have another Idea how to manage it?
In the uploaded picture is an part of the code.
Yours,
Chris
( If you don´t see the Pic, here´s the code:
MainCalss:
class Program : FormsWatchface
{
ClockViewModel _viewModel;
protected override void OnCreate()
{
base.OnCreate();
var watchfaceApp = new TextWatchApplication();
_viewModel = new ClockViewModel();
watchfaceApp.BindingContext = _viewModel;
LoadWatchface(watchfaceApp);
}
protected override void OnTick(TimeEventArgs time)
{
base.OnTick(time);
if (_viewModel != null)
{
_viewModel.Time = time.Time.UtcTimestamp;
}
}
protected override void OnAmbientChanged(AmbientEventArgs mode)
{
base.OnAmbientChanged(mode);
}
protected override void OnAmbientTick(TimeEventArgs time)
{
base.OnAmbientTick(time);
}
static void Main(string[] args)
{
var app = new Program();
Forms.Init(app);
FormsCircularUI.Init();
app.Run(args);
}
}
