Thread: Need help editing the size of a JButton!?!?

My two buttons "Calculate" and "Translate" is taking up the entire portion of their respected panel when added. How can I shrink the size of the button so it looks normal?

What have you tried?
How is the layout managed? ...with a layout manager or other?

 
//This is where I am creating my mainPanel1 and mainPanel2 layout and borders. 
 
Border lineBorder = new LineBorder(Color.BLUE, 2);
        mainPanel1 = new JPanel(new GridLayout(4,1));
        mainPanel1.setBorder(BorderFactory.createTitledBorder(lineBorder, "COLOR --> VALUE", 1, 2, null,Color.GREEN));
        mainPanel2 = new JPanel(new GridLayout(3,1,5,5));
        mainPanel2.setBorder(BorderFactory.createTitledBorder(lineBorder, "VALUE --> COLOR", 1, 2, null,Color.GREEN));
 
//This is where I'm adding my calculate1 button to my mainPanel1 and calculate2 button to my mainPanel2
 
calculate1 = new javax.swing.JButton();
        calculate1.setText("CALCULATE");
        mainPanel1.add(calculate1);
        calculate1.addActionListener(new java.awt.event.ActionListener(){
            public void actionPerformed(java.awt.event.ActionEvent evt){
                calculate1ActionPerformed(evt);
            }
        });
 
        calculate2 = new javax.swing.JButton();
        calculate2.setText("TRANSLATE");
        p2a.add(calculate2);
        calculate2.addActionListener(new java.awt.event.ActionListener(){
            public void actionPerformed(java.awt.event.ActionEvent evt){
                calculate2ActionPerformed(evt);
            }
        });

--- Update ---

I have tried doing a set-dimensions that didn't work. I tried messing with my mainPanel 1 & 2 array size specifying new horizontal and vertical gaps but that didn't work either. I tried doing a set-location I believe it was to left or right or middle and that didn't do anything either.

There are several methods that would set a dimension for a component, (some of which have been depreciated). Can you post a SSCCE that shows where you are setting the size?
Layout managers (GridLayout) will set the size of each component to or greater than their preferred size, have you set the preferred size?

Hello.
You may set the dimensions using setPreferredSize() or setSize() methods.
You can also set the X and Y location for the buttons.
Just check the API - JButton (Java Platform SE 7 )
Let us know if the problem is resolved.

Syed.

I was hoping I wouldn't have to do this but I can't get it to work by doing the set dimensions. I'm posting it all below here. I commented above the line where I was trying to set the dimensions of the button "calculate". It's about 1/3 of the way down above all my public void functions. There is some functionality that is not being used so I apologize for any unorganized sections. I'm still in the building stage. That and I'm a newbie.
