Spectrum.Create method 

 

Remarks 

 

Creates an instance of the Spectrum class: once created, the Spectrum will stay active until the termination of the container application: being a graphical object, the Spectrum needs to be associated to an existing window that will be used as a surface for the graphic rendering: this window can be changed at a later time through the Spectrum.SetHwnd method. 

 

Once created, by default the Spectrum is still not visible: you must make a call to the Spectrum.Show method in order to display it. 

 

Note that you can have a different Spectrum for each of the allocated players: for further details about using the embedded Spectrum refer to the Spectrum class section. 

 

For details about using Visual Feedbacks refer to the How to use embedded Visual Feedbacks section.
