Description
Indicates whether the TGraphicsObject object has acquired a handle to the underlying GDI object.
Use HandleAllocated to determine whether the Handle property is set for the graphics object. HandleAllocated indicates whether the underlying GDI object has been acquired. Use HandleAllocated rather than reading the Handle property. When an application reads the Handle property, TGraphicsObject descendants automatically create the underlying GDI object and return its handle if the property had not been previously set.
