COM Objects > SpectrumEnh object > Methods

Remarks

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.
