DK for ActiveX | TatukGIS_XDK11.ITGIS_DynamicAggregatorAbstract.HideShape | Methods | Properties

Mark shape as hidden during aggregation cycle. Prevents source shape rendering.

Available also on: Delphi | .NET | Java | Python.

// C#
public void HideShape(
  OleVariant _uid
);

' VisualBasic
Public Sub HideShape(
  ByVal _uid As OleVariant
)

// Oxygene
public
  procedure HideShape(
    _uid : OleVariant
  );

PURPOSE:Hide source shapes during aggregation. When creating aggregated shape from multiple sources, hide originals to avoid double-rendering.

BEHAVIOR:Records UID as hidden (internal tracking). Layer skips rendering shapes with hidden UIDs. Called during Prepare(). Hiding cleared after draw cycle (clearContext).

USAGE:Hide sources:aggregator.HideShape(shape1.UID); aggregator.HideShape(shape2.UID); { don't draw originals }

CONSTRAINTS:Must call during Prepare(). UID must be valid. Hidden state cleared after draw (per-cycle).
