UiTimer Class

Package: GHIElectronics.Endpoint.UI
Namespace: GHIElectronics.Endpoint.UI

Thread-safe periodic callback that runs on the UI thread. The callback fires inside UI.Run's LVGL pump every periodMs milliseconds, so widget updates in it are safe (LVGL itself is single- threaded). Dispose cancels the timer. Create / SetPeriod / Dispose are safe from any thread; the body runs on the UI thread.

class UiTimer : public IDisposable {};

Constructors

UiTimer(uint periodMs, Action callback)

UiTimer(uint32_t periodMs, const Action& callback);

Create a periodic timer that fires callback on the UI thread.

Parameter	Type	Description
periodMs	uint	Period in milliseconds between callbacks.
callback	Action	Delegate to invoke on each tick; runs on LVGL's event thread so widget updates are safe.

UiTimer(TimeSpan period, Action callback)

UiTimer(Core::TimeSpan period, const Action& callback);

Create a periodic timer with a System.TimeSpan period (clamped to at least 1 ms).

Parameter	Type	Description
period	TimeSpan	Period between callbacks.
callback	Action	Delegate to invoke on each tick; runs on the UI thread.

Methods

Dispose()

void Dispose();

Cancel the timer and release its pinned callback. Idempotent.

SetPeriod(TimeSpan period)

void SetPeriod(Core::TimeSpan period);

Change the timer period (clamped to at least 1 ms). Safe to call from any thread.

Parameter	Type	Description
period	TimeSpan	New period.

SetPeriod(uint periodMs)

void SetPeriod(uint32_t periodMs);

Change the timer period in milliseconds. Safe to call from any thread.

Parameter	Type	Description
periodMs	uint	New period in milliseconds.
