您可以创建自定义按钮.
You can create a custom button.
一种方法是对按钮使用CardLayout
并向其中添加JTextField
和JLabel
.在按钮的ActionListener
中,如果按下按钮,则显示文本字段并禁用按钮.在字段中输入文本并点击 enter 后,带有show的标签和按钮将被启用.
One way is to use a CardLayout
for the button and add a JTextField
and a JLabel
to it. In the ActionListener
of the button, if the button is pressed, you show the text field and disable the button. After you enter your text in the field and hit enter, the label with show, and the button is enabled.
