Tango ATK Tutorial

The following screen shot shows a numberSpectrumViewer. Note that the table on the right,
has been displayed using the chart menus under the right mouse button.
ATK does not provide any component for setting a NumberSpectrum attribute.
StringSpectrum attributes
By string spectrum attribute we mean any Tango Attribute whose format is “Spectrum” and
whose data type is DevString.
The SimpleStringSpectrumViewer is used to display the value of a StringSpectrum attribute.
The SimpleStringSpectrumViewer displays the spectrum attribute as a scrolled text. Each
string element of the spectrum is displayed in a new line. The code sample is very similar to
the one given in the previous section for the use of NumberSpectrumViewer. You just need to
replace NumberSpectrumViewer by SimpleStringSpectrumViewer and replace
INumberSpectrum by IStringSpectrum.
