SCOPE CHANGED signal
Emits SCOPE_CHANGED signal.
In-ports
trigger <any> (dynamic) — triggers SCOPE_CHANGED signal.
Out-ports
output <Signal> — emits SCOPE_CHANGED signal event.
Overview
The SCOPE CHANGED signal is used to notify widgets of an upcoming data scope change. It emits a SCOPE_CHANGED signal on the output port immediately after its initialization. If the trigger port is connected, the component will wait for an event on the trigger port before emitting the signal. The component emits a SCOPE_CHANGED signal every time it receives an event on the trigger port.
The effect of the SCOPE_CHANGED signal on a widget depends on the widget's implementation. Widgets that react to the SCOPE_CHANGED signal may reset their internal state or visually indicate the transition by fading.
