Bug 230071 Snippet223 requires an image
I just tried to run Snippet223 and it fails trying to acquire the 'eclipse.png' image...all the other snippets I've seen are self-contained (one of their best features...;-).
examples/org.eclipse.swt.snippets/src/org/eclipse/swt/snippets/Snippet258.java
ToolBar toolBar = new ToolBar (shell, SWT.FLAT);
			ToolItem item = new ToolItem (toolBar, SWT.PUSH);
			item.setImage (image);
			item.addSelectionListener(new SelectionAdapter() {
				public void widgetSelected(SelectionEvent e) {
					text.setText("");
					System.out.println("Search cancelled");
				}
			});
		}
		text.setLayoutData(new GridData(GridData.FILL_HORIZONTAL));
		text.setText("Search text");
		text.addSelectionListener(new SelectionAdapter() {
			public void widgetDefaultSelected(SelectionEvent e) {
				if (e.detail == SWT.CANCEL) {
					System.out.println("Search cancelled");
				} else {
					System.out.println("Searching for: " + text.getText() + "...");
				}
			}
		});
		shell.pack();
		shell.open();
		while (!shell.isDisposed()) {
			if (!display.readAndDispatch()) display.sleep();
		}
		if (image != null) image.dispose();
		display.dispose();
	}
}
