How to get rangeEnd from AudioWaveform while dragging

[oskarsh]

Hey, how can I get the range end value from the AudioWaveform. The AudioWaveform is connected to a AudioLoopPlayer.

I tried to register a control callback but seems like it is not triggered when the range end changes.

What I am trying to achieve is that I want the AudioWaveform be clickable and play the sample. I am using a trigger panel for this. The trigger panel cancels out all events to the AudioWaveform range end slider. So I will need to dynamically resize the trigger panel on the left side of the range end slider. To have the left side clickable and play a sample while I can still drag the range end slider.
