[SOLVED] Navigation between swing forms

stevedb · #1 (**permalink**) 03-30-2008, 03:56 PM

Hi all,

I am using Netbeans version 6 to create a tutorial application and I cannot seem to find a way to use a button to open up a different form.

I have created the forms using JFrames with a Main Menu, then 2 other menu forms that I want to have the user press a button to take them to one of the 2 other menu forms.

I know that I need to use Action Listeners but it is the code to open the form when the button is pressed which is eluding me.

Thanks in advance
Steve

Let's see your code.

Here it is for the Main Menu Form, the other forms are called 'UseCaseTutorialMenu.java' and 'ActivityDiagramTutorialMenu.java':

public class UMLMenu extends javax.swing.JDialog {

/** Creates new form UMLMenu */
public UMLMenu(java.awt.Frame parent, boolean modal) {
super(parent, modal);
initComponents();
}

I'm unable to compile your file. The forum software can mangle code that is posted outside the [code] [/code] tags. I have no patience for dealing with the GroupLayout machine code. If you can edit your post and post formatted code I'll try again.

Here it is again, sorry didnt realise that it needed to be in the [code] tags
