loadImage - use in inline function

[DanH]

I was previously loading this image via LAF but now I have to draw my knob in an inline function so how do I get the image back in? The below results in the image being undefined.... Obviously it's expecting a string

const var HaloSlider = Engine.loadImageIntoPool("{PROJECT_FOLDER}H3 KB BACK 1.png");

inline function drawModSlider(g, obj)
{

		g.drawImage(HaloSlider, obj.area, 10, 0);

@DanH If this is a paint routine you load the image into the panel, if it's a look and feel function you load the image into the laf object.

[DanH]

@d-healey Is it either of those though? I'm drawing a Slider, so not a panel, and I'm not using LAF (I don't think?!)

[d.healey]

@DanH I'll need to see more code to know what you're doing

[Christoph Hart]

I'm pretty sure you'll be passing inline function drawModSlider(g, obj) into a registerFunction() call of a a LAF object, otherwise it won't do anything.

//KnobLaf3.loadImage("{PROJECT_FOLDER}H3 KB BACK 1.png", "H3KBBK");
const var HaloSlider = Engine.loadImageIntoPool("{PROJECT_FOLDER}H3 KB BACK 1.png");

inline function drawModSlider(g, obj)
{
	local ar = Rectangle(obj.area).reduced(THICKNESS/2 + 2);
	local n = Rectangle(0.0, 0.0, 1.0, 1.0);

	local track = Content.createPath(); track.setBounds(n);
	track.addArc(n, START-0.05, START + ARC_WIDTH+0.05);
	
	
	if(obj.modulationDragState)
	{
		if(obj.modulationDragState == 2)
		{
			g.setColour(obj.itemColour1);
		}
		else
		{
			g.setColour(0x44FFFFFF);
		}
		
		g.fillEllipse(ar.reduced(-THICKNESS/2 - 1));
	}
	
	g.setColour(0x77000000);
	g.drawPath(track, ar, THICKNESS);
	
	
	local modRange = Content.createPath(); modRange.setBounds(n);
	modRange.addArc(n, START + obj.modMinValue * ARC_WIDTH,
					   START + obj.modMaxValue * ARC_WIDTH);
					   
	g.setColour(0x22FFFFFF);
	g.drawPath(modRange, ar, THICKNESS - 2);
	
	local value = Content.createPath(); value.setBounds(n);
	value.addArc(n, START + obj.valueNormalized * ARC_WIDTH,
					START + Math.range(obj.scaledValue + obj.addValue, 0.0, 1.0) * ARC_WIDTH);
					
	g.setColour(obj.itemColour1);
	g.drawPath(value, ar, THICKNESS - 4);
	
	local thumb = Content.createPath(); thumb.setBounds(n);
	thumb.addArc(n, START + obj.valueNormalized * ARC_WIDTH - 0.01,
					START + obj.valueNormalized * ARC_WIDTH + 0.01);
	
	g.setColour(Colours.white);
	g.drawPath(thumb, ar, p);
	
	g.drawAlignedText(obj.valueAsText, ar, "centred");
	g.setColour(0x55FFFFFF);
	g.drawAlignedText(obj.text, ar, "centredBottom");
}

@DanH I don't see anywhere that you're applying the function to a component, but 99% sure it's going to be laf.

@Christoph-Hart said in loadImage - use in inline function:

registerFunction()

ah ok that makes more sense

I can see it now
