Remarks

The canvas panel is a designer friendly panel that allows widgets to be laid out at arbitrary locations, anchored and z-ordered with other children of the canvas. The canvas is a great widget for manual layout, but bad when you want to procedurally just generate widgets and place them in a container (unless you want absolute layout).

Many Children Absolute Layout Anchors
