OnWaveformAnalyzerLineMoved event

Previous pageReturn to chapter overviewNext page



Occurs when a graphic item of type "vertical line" inside the waveform analyzer is being moved through the mouse or through the WaveformAnalyzer.GraphicItemHorzPositionSet method.


This event replaces the usage of the CallbackWaveformAnalyzerLineMoved 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 graphic items management on the waveform analyzer refer to the How to add graphic items to the Waveform analyzer section.

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.
