update...
I figured it out...
I found the snippet in Docs and modified it for my usage. Yee.
const var rm = Engine.getGlobalRoutingManager();
const var mc = rm.getCable("bars");
const var pnlMasterPlayheadBars = Content.getComponent("pnlMasterPlayheadBars");
pnlMasterPlayheadBars.data.value = 0;
mc.registerCallback(function(value)
{
pnlMasterPlayheadBars.data.value = value;
pnlMasterPlayheadBars.repaint();
//Console.print(value);
}, AsyncNotification);
pnlMasterPlayheadBars.setPaintRoutine(function(g)
{
var a = this.getLocalBounds(0);
g.fillAll(this.get("bgColour"));
g.setColour(Colours.withAlpha(this.get("textColour"), 1.0));
var x = a[2] / 100 * (this.data.value * 100);
g.drawVerticalLine(x, 0, a[3]);
});
