AWT Controls

Basic Controls

AWT ships practical input controls that all extend Component:

• Label - static text.
• TextField - one-line input.
• Button - clickable action.
• Checkbox and CheckboxGroup - toggles and radio groups.
• TextArea - multi-line text.
• Panel - a container to group controls.

Code

Label name = new Label("Name:");
TextField field = new TextField(15);
Button go = new Button("Submit");
Checkbox agree = new Checkbox("I agree");
TextArea notes = new TextArea(4, 25);
Panel p = new Panel();
p.setLayout(new FlowLayout());
p.add(name); p.add(field); p.add(go);
add(p);
add(agree);
add(notes);

Key Points

• Use TextField for single-line and TextArea for multi-line input.
• CheckboxGroup makes mutually exclusive radio buttons.
• Panels group related controls and get their own layout manager.
