modifier

The effective SwingModifier chain currently declared on this node, including any inherited component defaults applicable to this component followed by elements passed directly on the node's own modifier.

Walk it with SwingModifier.foldIn, which hands out a SwingModifier.Element; read the name and declaredValues of each one that is a SwingModifier.InspectableElement to show what the component carries.

A composed entry appears as the entries its factory returned for this component.

It is the whole effective declared modifier chain, placement included: an element saying where the component sits in its parent stands in it alongside the ones saying what it looks like. Inherited defaults are flattened into their effective property elements; provider-key boundaries are not preserved and key names are not presented as synthetic modifier elements.

It answers whatever the composition declared last, whether or not the pass that declared it had anything to write, so it never lags the composition. Every node holds its modifier whatever org.jetbrains.compose.swing.tooling.isDebugInspectorInfoEnabled says; what that switch decides is whether a tool can reach the node at all.
