OTL Syntax
EventSource = HMI.ScreenClosedEventSource(ScreenTerm);Description
The ScreenClosedEventSource term accepts a Screen object that is to be made an event source. This term enables an OTX sequence to use a Screen as a source for events in the context of the OTX EventHandling extension. A Screen shall trigger an event every when the specified screen is closed. This can be used within a event:WaitForEventAction to continue execution after a screen was closed.
Return Value
The Term returns the value, see table below.
In OTX, Terms are categorized according to its return data type!
| Data Type | Description |
| EventSource | Event source from a screen object. |
Properties
| Name | Data Type | Class | Default | Cardinality | Description |
| Screen | Screen | Term | - | [1] | Represents the Screen that shall be connected to the event source. |
OTL Examples
package HMI.ScreenSignature ScreenSignature1(ref Integer ScreenInOutParameter1);
/// Global Declarations
public procedure main()
{
/// Local Declarations
HMI.Screen ScreenHandle1;
Integer Integer1;
EventHandling.EventSource EventSource1;
/// Flow
HMI.OpenScreen(ScreenHandle1, ScreenSignature1, {ScreenInOutParameter1 = Integer1}, false);
HMI.CloseScreen(ScreenHandle1);
EventSource1 = HMI.ScreenClosedEventSource(ScreenHandle1);
}
