@sapui5/types: sap/gantt/simple/DeltaLine is missing the settings constructor overload

Summary

The TypeScript definition for sap/gantt/simple/DeltaLine in @sapui5/types appears to be incomplete.

At runtime, DeltaLine supports being created with a settings object, but the current type definition only exposes constructor(sId?: string).

This breaks TSX / JSX scenarios and also plain TypeScript code that instantiates DeltaLine with settings.

Affected Package

• @sapui5/types: ~1.142.13

Affected UI5 Class

• sap/gantt/simple/DeltaLine

Current Typing

declare module "sap/gantt/simple/DeltaLine" {
  export default class DeltaLine extends UI5Element {
    constructor(sId?: string);
  }
}

Expected Typing

declare module "sap/gantt/simple/DeltaLine" {
  export default class DeltaLine extends UI5Element {
    constructor(settings?: $DeltaLineSettings);
    constructor(id?: string, settings?: $DeltaLineSettings);
  }
}

Actual Behaviour

TypeScript rejects valid code like this:

import DeltaLine from "sap/gantt/simple/DeltaLine";

const deltaLine = new DeltaLine({
  stroke: "red",
  timeStamp: "2026-01-01T00:00:00",
  endTimeStamp: "2026-01-01T12:00:00",
  visibleDeltaStartEndLines: false,
});

Expected Behaviour

The code above should type-check, because DeltaLine accepts a settings object at runtime.

Why This Matters

• It forces local type workarounds or wrapper classes.
• It breaks UI5 JSX/TSX runtimes that derive prop types from UI5 constructor signatures.
• It is inconsistent with the exported $DeltaLineSettings interface, which already exists.

Reproduction

1. Install @sapui5/types@~1.142.13
2. Create a TypeScript file with the example above
3. Run TypeScript type-checking
4. Observe that the constructor signature does not accept the settings object

Environment

• TypeScript: project using strict mode
• UI5 typings: @sapui5/types@~1.142.13
• UI5 runtime used in app: 1.142.13

Suggested Fix

Please add the missing settings-based constructor overloads for sap/gantt/simple/DeltaLine.

The class already exports $DeltaLineSettings, so the constructor typing likely only needs to be aligned with the actual runtime API.

Additional Context

In our project we had to introduce a local wrapper around sap/gantt/simple/DeltaLine only to bridge the missing constructor typing. The runtime API itself works correctly; the issue is limited to the TypeScript declaration.

Search the @sapui5/types declaration for sap/gantt/simple/DeltaLine and compare its constructors with neighboring UI5 classes and the existing $DeltaLineSettings interface. Add the two settings-based overloads described in the issue, then run the TypeScript reproduction or project type-check to verify that the shown instantiation is accepted.
