Syntax

// C#
public event TGIS_PaintEvent BeforePaintEvent

  add {}
  remove {}
}
' VisualBasic
Public Custom Event BeforePaintEvent As TGIS_PaintEvent
  AddHandler(ByVal value As TGIS_PaintEvent)

Value

Remarks

This even can be quite costly. To maintain compatibility with the old code we guarantee proper Graphics context even on SharpDX renderer. Try to replace this event with BeforePaintRendererEvent, which is always fast.
