If I have this right, JTable gets the map initialised via this code in
BasicTableUI.java
InputMap getInputMap(int condition) {
if (condition == JComponent.WHEN_ANCESTOR_OF_FOCUSED_COMPONENT) {
InputMap keyMap =
(InputMap)DefaultLookup.get(table, this,
"Table.ancestorInputMap");
InputMap rtlKeyMap;
if (table.getComponentOrientation().isLeftToRight() ||
((rtlKeyMap = (InputMap)DefaultLookup.get(table, this,
"Table.ancestorInputMap.RightToLeft")) == null)) {
return keyMap;
} else {
rtlKeyMap.setParent(keyMap);
return rtlKeyMap;
}
}
return null;
}
This uses the shared defaults for the L&F.
I imagine that sharing is by far the most efficient thing to do for 99% of
uses, in which case I expect that somewhere there's some doc telling apps that
if they mess with the map for a component, they need to make a copy first ? But
how to do that ? And the author of the code above that modified the shared map
presumably was ignorant of this.
