Why does a slider emit change events and not action events?
CHAPTER SUMMARY
1. User-interface components are arranged by placing them inside containers.
Containers can be placed inside larger containers.
2. Each container has a layout manager that directs the arrangement of its
components.
3. Three useful layout managers are the border layout, flow layout, and grid
layout.
4. When adding a component to a container with the border layout, specify the
NORTH
,
EAST
,
SOUTH
,
WEST
, or
CENTER
position.
5. The content pane of a frame has a border layout by default. A panel has a flow
layout by default.
6. For a small set of mutually exclusive choices, use a group of radio buttons or a
combo box.
7. Add radio buttons into a
ButtonGroup
so that only one button in the group is
on at any time.
8. You can place a border around a panel to group its contents visually.
9.
For a binary choice, use a check box.
10. For a large set of choices, use a combo box.
11. Radio buttons, check boxes, and combo boxes generate action events, just as
buttons do.
