Dynamic sizes in QtQuick 2.0 application

[Axtroz]

Hello,

I'm struggling to grasp the concept behind QtQuick.Layouts.
I want to create a 3 column UI that fills up the window without setting fixed sizes. Then in each column there should be multiple rows with no fixed widths.
So far, I have been unable to achieve this with the code below, instead it shows 3 red, green, blue columns next to each other. Is there some Layout limitation in place or the whole solution is wrong and I should use other means to achieve this?
All the examples I found use a fixed width/height, but that doesn't work for my goal.
Thank you!

	spacing: 2
 
	Rectangle {
		Layout.fillWidth: true
		Layout.fillHeight: true

		ColumnLayout {
			spacing: 2
 
			Rectangle {
				Layout.fillWidth: true
				height: 32
				color: "black"

What is the output you expect and how does it differ from what you achieve right now? Aren't you missing an "anchors.fill: parent" binding in the column layout? Right now you layout has null size.

Oh wow, this was embarassing. I've been overlooking that half the day. I guess one could go so on on coffee only. Thank you once again for taking the time to answer my (obvious and ignorant) question.
