writeObject back to summary

private void writeObject(ObjectOutputStream s) throws IOException

Hides javax.swing.JComponent.writeObject.

Doc from javax.swing.JComponent.writeObject.

Before writing a JComponent to an ObjectOutputStream we temporarily uninstall its UI. This is tricky to do because we want to uninstall the UI before any of the JComponent's children (or its LayoutManager etc.) are written, and we don't want to restore the UI until the most derived JComponent subclass has been stored.

Parameters

s:ObjectOutputStream: the ObjectOutputStream in which to write

Annotations

@Serial

Exceptions

IOException:
