Container

Container children queries

Function	Container	JLayeredPane	JToolBarJPopupMenu	JMenuBar
size	getComponentCount			getMenuCount
at	getComponent		getComponentAtIndex (deprecated in JMenuBar) (used from BasicToolBarUI)	getMenu (if JMenu)
toArray	getComponents
contains	by getParent
indexOf	loop	getIndexOf	getComponentIndex (brilliant implementation) (used from BasicToolBarUI/internally)

Container children commands

Command	Container	JPopupMenu
add	add
addAt	add	insert (really ingenious implementation, seems the writer was not aware add(index) existed) (used internally, from JMenu)
multiple add	loop over add
replace, set	not directly, remove + add
move	add (constraints are lost) setComponentZOrder (1.5)
remove	remove
remove(index)	remove
multiple remove	loop over remove
clear	removeAll

Container modification implementations

JToolBar: addImpl: overridden to setDefaultCapable to false for JButton

CellRendererPane: addImpl: don't do anything if already a child

JRootPane: always move glass pane to front afterwards (breaks some invariants)

JViewport: addImpl calls setView, which calls super.addImpl; remove(component) removes listener (broken)

JTabbedPane: calls addImpl directly; add does much magic; remove delegates to removeTabAt

JApplet/JDialog/JFrame/JWindow/JInternalFrame: root pane checking

JSplitPane: add removes old component in same place, remove(2x)/removeAll reset cached components, all call revalidate/repaint???

JTabbedPane: remove

JMenu: delegates to its popup menu

JPopupMenu: remove with new IllegalArgumentException (purpose?), insert(Component ,index)

JLayeredPane: index/layer conversion; validateOptimizedDrawing

Container modification delegates:

JScrollPane: setCorner, setViewport(View), setXXXHeader(View), setXXXScrollBar

JViewport: setView

JSplitPane: setXXXComponent

JTabbedPane: addTab (3x), insertTab, removeTabAt

JSlider: setLabelTable

JLayeredPane: setLayer <- setLayer, setPosition <- moveToFront, moveToBack

JRootPane/RootPaneContainer: setXXXPane

Container notification

JComponent: both: "ancestor" property, more

JMenuBar: (un-)register with KeyboardManager

JRootPane: internal, enable key events?

JTable: scroll pane, focus property change listener

JTextComponent: clear focused component (why?)

Other

JColorChooser: panels

JFileChooser: accessory

JTextPane: insertComponent (-:

JToolBar:

margin/borderPainted

weird LayoutManager strategy

invalidate from updateUI?
