Class UIManager

java.lang.Object
vaadinx.swing.UIManager
All Implemented Interfaces:
Serializable
public class UIManager extends Object implements Serializable
Port of UIManager. Path 2 (external) of the icon-rendering plan: a hand-picked lookup table maps the OptionPane.* icon keys to VaadinIcon glyphs via VaadinIconAdapter, so dialog-heavy migrated code that pulls icons by key (e.g. JOptionPane.showMessageDialog(parent, msg, "title", PLAIN_MESSAGE, UIManager.getIcon("OptionPane.errorIcon"))) reaches the same Vaadin glyph the JOptionPane static-factory path picks internally.

L&F machinery is permanently out of scope per R_match_swing_errors sub-bucket (b); UIDefaults, LookAndFeel install/lookup, and the addPropertyChangeListener surface aren't ported. The other typed-getter family (getColor(Object), getFont(Object), ...) compiles for import-swap but stubs through EHelper.onUnimplemented(String, String, Object...) so call sites surface in migration logs rather than fail to compile.

Unknown icon keys log via EHelper.onUnimplemented(String, String, Object...) and return null, matching the JDK contract that UIManager.getIcon may return null for un-installed keys.

The supported key set today is the four OptionPane.* messageType icons. Adding more keys is purely additive — wire a new entry in ICON_KEYS when a future component needs the L&F-key shape (e.g. FileChooser.directoryIcon, Tree.openIcon). Doing so preemptively violates R_infra_not_surface.

      Answers from LookAndFeelDefaults' Metal table for the colour keys it covers, and keeps the WARN for the rest.

      The returned instance is a ColorUIResource, which is load-bearing rather than incidental: passing it straight back into setBackground is how a migrated app says "reset me to the default", and the marker is what makes that render as the theme's colour instead of as a pinned literal (D_theme_is_lookandfeel).
