这是修改后的SWT代码段，显示了如何将气球工具提示添加到SWT
Text实例。
下次，请考虑更具体地询问，我现在不这样做，如果您要查找的是..
import org.eclipse.swt.SWT;import org.eclipse.swt.events.FocusEvent;import org.eclipse.swt.events.FocusListener;import org.eclipse.swt.graphics.Point;import org.eclipse.swt.layout.RowLayout;import org.eclipse.swt.widgets.Display;import org.eclipse.swt.widgets.Shell;import org.eclipse.swt.widgets.Text;import org.eclipse.swt.widgets.ToolTip;public class TextFieldTooltip { public static void main(String[] args) { Display display = new Display(); Shell shell = new Shell(display); shell.setLayout(new RowLayout(SWT.VERTICAL)); final ToolTip tip = new ToolTip(shell, SWT.BALLOON); tip.setMessage("Here is a message for the user. When the message is too long it wraps. I should say something cool but nothing comes to my mind."); Text tfTooltip = new Text(shell, SWT.BORDER); tfTooltip.setText("sample text field"); tfTooltip.addFocusListener(new FocusListener() { @Override public void focusLost(FocusEvent e) { tip.setVisible(false); } @Override public void focusGained(FocusEvent e) { Text actionWidget = (Text) e.widget; Point loc = actionWidget.toDisplay(actionWidget.getLocation()); tip.setLocation(loc.x + actionWidget.getSize().x - actionWidget.getBorderWidth(), loc.y); tip.setVisible(true); } }); Text tfNext = new Text(shell, SWT.BORDER); tfNext.setText("TF without tooltip"); shell.setBounds(50, 50, 300, 200); shell.open(); while (!shell.isDisposed()) { if (!display.readAndDispatch()) display.sleep(); } display.dispose(); }}
