A ScrolledWindow displays a portion of a larger window through a view with scrollbars. The user can use the scrollbars to view the entirety of the child window. Let's take a look at an example from TestGTK.
Example 6-5. TestGTK.java - ScrolledWindow
public void createScrolledWindows() { final Dialog win = new Dialog(); win.setTitle("Scrolled Windows"); win.setDefaultSize(200, 200); ScrolledWindow scrolled_window = new ScrolledWindow(null, null); scrolled_window.setBorderWidth(10); scrolled_window.setPolicy(PolicyType.AUTOMATIC, PolicyType.AUTOMATIC); ((Box) (win.getDialogLayout())).packStart(scrolled_window); scrolled_window.show(); Table table = new Table(20, 20, true); table.setRowSpacing(10); table.setColumnSpacing(10); scrolled_window.addWithViewport(table); table.show(); for (int i = 0; i < 20; i++) for (int j = 0; j < 20; j++) { ToggleButton button = new ToggleButton("button (" + i + "," + j + ")", false); table.attach(button, i, i + 1, j, j + 1, AttachOptions.EXPAND.or(AttachOptions.FILL), AttachOptions.EXPAND.or(AttachOptions.FILL), 0, 0); button.show(); } Button button = new Button("close", false); button.addListener(new ButtonListener() { public void buttonEvent(ButtonEvent event) { if (event.isOfType(ButtonEvent.Type.CLICK)) { win.destroy(); } } }); ((Box) win.getActionArea()).packStart(button, false, false, 10); button.show(); win.show(); win.run(); }
