如何在不更改其他元素位置的情况下使组件不可见 [英] How to make a component invisible, without changing the location of other elements

问题描述

有两个按钮:下一步"和"返回"以传递列表.到达终点时，下一步"按钮消失，但后退"按钮不应跳到她的位置.我使用setVisible (false)，但是按钮返回"跳到下一步"的位置.位置管理器是GridBagLayout.

There are two buttons: "Next" & "Back" to pass on the list. When the reached the end, the button "Next" to disappear, but the button "back" should not jump to her place. I use the setVisible (false), but the button 'Back' jump to the place of the "Next". Location manager is GridBagLayout.

推荐答案

将按钮与一个或多个空JPanel(或JLabel)一起放置在具有CardLayout的容器JPanel中.当您想隐藏按钮时，只需在容器中交换卡即可.

Place the button in a container JPanel with CardLayout together with one more empty JPanel (or JLabel). When you would like to hide the button just swap cards in the container.
