Java 使用卡片布局进行验证
有一个单J框架,我在其中放置了两个面板&两个面板都有卡片布局 通过图像J,具有两个面板的框架是一个 panel pane>>我将调用panel1、panel2、panel3,其中所有这3个面板都有一些控件,如JtextField、jComboBox等 按钮窗格>>在此面板中,按下“下一步”时,面板具有按钮“下一步”和“上一步”(如果面板窗格显示panel1,则为panel1控件)以进行验证 像那样等等 代码如下Java 使用卡片布局进行验证,java,swing,validation,cardlayout,Java,Swing,Validation,Cardlayout,有一个单J框架,我在其中放置了两个面板&两个面板都有卡片布局 通过图像J,具有两个面板的框架是一个 panel pane>>我将调用panel1、panel2、panel3,其中所有这3个面板都有一些控件,如JtextField、jComboBox等 按钮窗格>>在此面板中,按下“下一步”时,面板具有按钮“下一步”和“上一步”(如果面板窗格显示panel1,则为panel1控件)以进行验证 像那样等等 代码如下 package Code; /** * * @author Ro
