OnWaveformAnalyzerGraphicItemClick event

Previous pageReturn to chapter overviewNext page

Remarks

 

Occurs when a mouse button is clicked over a graphic item available on the waveform analyzer.

 

This event replaces the usage of the CallbackWaveformAnalyzerGraphItemClick delegate and is only intended for usage with applications developed using Visual Basic 6 (which results unreliable when dealing with delegates and callbacks) and, in order to be enabled, requires a call to the COMEventsEnable method.

 

For details about the use of the Waveform Analyzer refer to the How to use the Waveform Analyzer section.

For further details about methods of the Waveform Analyzer refer to the WaveformAnalyzer class section.
