OnWaveformAnalyzerPaintDone event

Previous pageReturn to chapter overviewNext page



Occurs when the waveform analyzer has completed its graphic rendering, allowing to add custom graphics directly from the container application's code.


This event replaces the usage of the CallbackWaveformAnalyzerPaintDone 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.
