Syntax

C++/CLI

C++

public virtual RasterMagnifyGlassCrosshair Crosshair { get; set; }

public: 
virtual property RasterMagnifyGlassCrosshair Crosshair { 
   RasterMagnifyGlassCrosshair get(); 
   void set (    RasterMagnifyGlassCrosshair ); 
}

public:  
   virtual property RasterMagnifyGlassCrosshair^ Crosshair 
   { 
      RasterMagnifyGlassCrosshair^ get() 
      void set(RasterMagnifyGlassCrosshair^ value) 
   }

Property Value

The Crosshair type.

Remarks

Using the CrosshairWidth and CrosshairColor properties depends on the value of this property.

If it set to RasterMagnifyGlassCrosshair.Fine both of them will be used.

If it set to RasterMagnifyGlassCrosshair.None none of them will be used.
