Question

Need help!

In java swing, how can I jump back(open up) the hidden form from which the previous form had been generated?

Elaborating -> I made an object of form2 in form1, hid the 1st form and displayed the 2nd one. Now after a while I have to hide the form2 and open the original form1. How can I do that?

Form1 is a class in which I made an object of Form2 on a button click. I used setVisible to hide Form1 and then open Form2. Now Form2 is visible. Then on a button click on Form2, I need to dispose Form2 and unhide Form1. I don't know any function to unhide Form2, neither do I want to create a new object of Form1. — Snehil_V127, Apr 07 '14 at 14:28

You can use form.setVisible(true) and form.setVisible(false)

In form1 you'll put this under the button

form2 f2 = new form2(this);

In form2 you'll do this

f1.setVisible(false);

then when you go back

f1.setVisible(true);
this.dispose();

...but you will probably have to rerender? – chris polzer Apr 07 '14 at 14:22
I cannot do that because I don't want to create an object of Form1 in Form2. I need to unhide Form1 from Form2 – Snehil_V127 Apr 07 '14 at 14:29
You are going to have to create an object of Form1 in Form2 if you want to interact with it. – Leniaal Apr 07 '14 at 14:32
But wouldn't I lose the original Form1 and it's values then? – Snehil_V127 Apr 07 '14 at 14:40
@Snehil_V127 See the changes in my answer, f1 is defined in the constructor of form2 – Leniaal Apr 07 '14 at 14:45
@user1896006 I got it now. Thanks a lot :) – Snehil_V127 Apr 07 '14 at 15:12

Unless you have a really good reason to do something like this, then don't.

Instead, use a CardLayout which will allow you to move back and forward and set the currently active view at your hearts content
