推荐答案

您还可以尝试使用EmptyBorder在两个组件之间添加间隙.如果已经有边框，则可以将其与EmptyBorder结合使用以创建CompoundBorder.在下面的代码片段中，创建了一个新的CompoundBorder，它具有TitledBorder和EmptyBorder，后者在组件周围强制填充了1个像素.

You could also try using an EmptyBorder to put in gaps between the two components. If you already have a Border, you can use that in conjunction with an EmptyBorder to create a CompoundBorder. In the code fragment below, a new CompoundBorder is created that has a TitledBorder and an EmptyBorder which enforces a padding of 1 pixed around the component.

testPanel.setBorder(
   javax.swing.BorderFactory.createCompoundBorder(
      javax.swing.BorderFactory.createTitledBorder(
         null, "Border Title",
         javax.swing.border.TitledBorder.DEFAULT_JUSTIFICATION,
         javax.swing.border.TitledBorder.DEFAULT_POSITION,
         new java.awt.Font("Verdana", 1, 11)
      ),
      javax.swing.BorderFactory.createEmptyBorder(1, 1, 1, 1)
   )
);
