RAW FloatingTile & Listener from Connection instead of sliderValueChanged

[ustk]

@Christoph-Hart How can we use the listener from a connection (when the slider is updated from outside, not by click/drag)

class ExternalTestComponent : public hise::FloatingTileContent,
							  public juce::Component,
							  public juce::Slider::Listener
{
public:

	SET_PANEL_NAME("ExternalTestComponent");

	ExternalTestComponent(juce::FloatingTile* parent) :
		FloatingTileContent(parent),
		gainSlider("Gain"),
		gainConnection(&gainSlider, getMainController(), "Sine Wave Generator1")
		
	{
		addAndMakeVisible(gainSlider);
		gainSlider.setSliderStyle(Slider::RotaryHorizontalVerticalDrag);
		gainSlider.setTextBoxStyle(Slider::NoTextBox, false, 80, 40);
		gainSlider.setRange(0.0, 1.0);
		gainSlider.addListener(this);
	}

	~ExternalTestComponent()
	{
		gainSlider.removeListener(this);
	}
	
	void resized() override
	{
		auto area = getLocalBounds();
		gainSlider.setBounds(area.withSizeKeepingCentre(80, 120));
	}

	void paint(Graphics& g) override
	{
		g.fillAll(Colours::red.withMultipliedAlpha(0.3));

		g.setColour(Colours::blue);

		float barWidth = gainSlider.getValue() * 480.0;
		Rectangle<float> area (10.0, 10.0, barWidth, 40.0);
		g.fillRect(area);
	}

	void sliderValueChanged(juce::Slider* slider) override
	{
		if (slider == &gainSlider)
		{
			repaint();
		}
	}

	juce::Slider gainSlider;

	hise::raw::UIConnection::Slider<SineSynth::Gain> gainConnection;
};
};

@ustk I'd like to do this ideally from a DSP parameter with a unidirectional connection... Or better, is there a way to make a connection directly from a core.peak node, that would be killer :)

EDIT: I just realized that for my needs I will still need a timer, so it's not advantageous compared to drawing with Hise script...
