SpectrumEnh.Create method

Previous pageReturn to chapter overviewNext page



Creates an instance of the enhanced spectrum analyzer on the full client area of the given parent window. The parent window can be changed at a later time through the SpectrumEnh.SetHwnd method.


In case you should need to create the enhanced spectrum analyzer on a specific initial position and with a specific initial size you may use the SpectrumEnh.CreateNew method.


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


For further details about using the Enhanced Spectrum Analyzer refer to the SpectrumEnh section.
