import org.eclipse.swt.SWT;
import org.eclipse.swt.layout.GridData;
import org.eclipse.swt.layout.GridLayout;
import org.eclipse.swt.widgets.*;

public class SWTDialogExample {
    public static void main(String[] args) {
        Display display = new Display();
        Shell shell = new Shell(display);
        shell.setLayout(new GridLayout(2, false));

        // 创建一个标签控件
        Label label = new Label(shell, SWT.NONE);
        label.setText("标签内容：");

        // 创建一个文本框控件
        Text text = new Text(shell, SWT.BORDER);
        text.setLayoutData(new GridData(SWT.FILL, SWT.CENTER, true, false));

        // 创建一个按钮控件
        Button button = new Button(shell, SWT.PUSH);
        button.setText("获取标签内容");
        button.addListener(SWT.Selection, event -> {
            // 获取标签的文本内容并在控制台打印
            System.out.println("标签内容：" + label.getText());
        });

        shell.pack();
        shell.open();

        while (!shell.isDisposed()) {
            if (!display.readAndDispatch()) {
                display.sleep();
            }
        }

        display.dispose();
    }
}
