验证在添加组件并调用 setVisible() /javase/7/docs/api/java/awt/Window.html#pack%28%29\"rel =nofollow noreferrer> pack()
,如本相关示例中所述。您可能还需要采用适当的布局。按照此处的建议调用 repaint()
可能会修复症状但不是根本原因。
Verify that you invoke setVisible()
after adding components and calling pack()
, as discussed in this related example. You may also need to adopt an appropriate layout. Invoking repaint()
, as suggested here, may fix the symptom but not the underlying cause.
