问题 I have a CardLayout in which I add cards only as needed.

So, no error will be thrown if I ask it to show

JFrame whose content changes as we click on the different buttons

I am using Java's Swing here to make a UI application. I have a created a JFrame, with some buttons. When I click on this button, I want a new JFrame with some different content at this place. However, I do not want a new JFrame to load here. One approach, I know is of setting the visbility of the second JFrame to be True in the actionPerformed(ActionEvent obj) method of the button in the first JFrame. But it again loads a new JFrame and I don't want that. public class FirstUI extends JFrame { JButton but1; public FirstUI(){ but1= new JButton("Click here"); add(but1); XYZ obj= new XYZ(): but1

How to reload a JPanel?

由 蹲街弑〆低调 提交于 2019-12-04 09:04:58
I'm a java newbie... I need to know how to reload a JPanel ? I extended the JPanel class and created a panel that will run in a cardlayout in an Applet. I want this panel to reload/refresh after the user clicks a button in this panel. I tried including the revalidate () and repaint () methods (methods I don't understand well) in the ActionListener for the button but nothing happened. Can anyone throw some light on how to correctly refresh the whole panel? This works fine for me. But after an other _panel.revalidate(); _panel.repaint(); 来源： https://stackoverflow.com/questions/17608421/how-to

问题 I'm sure someone has asked this question before, but my google-fu is not strong today. I have a JFrame that uses a CardLayout as its manager.
