Question

I’m kinda new to java swing and I’m trying to do this by hand for practice. In the following example, I have a setup where I have a GridLayout to display fields the way I want. But I need to re-size the text fields, since I don’t want them to all be that constant size. I need some to be bigger or smaller. Is there a way to do this? Also is there a way to remove some of the padding after the labels?

public void setupFrame() {
    pnlTop.setLayout(new GridLayout(3, 4, 10, 10));

    lblClosetLoc.setText("Closet location:");
    lblPhone1.setText("Phone 1:");
    lblJackPaired.setText("Jack paired:");
    lblPhone2.setText("Phone 2:");
    lblCubicle.setText("Cubicle:");
    lblJackType.setText("Jack type:");      
    txtClosetLoc.setEditable(false);
    txtClosetLoc.setText("");       
    txtPhone1.setEditable(false);
    txtPhone1.setText("");      
    txtJackPaired.setEditable(false);
    txtJackPaired.setText("");      
    txtPhone2.setEditable(false);
    txtPhone2.setText("");      
    txtCubicle.setEditable(false);
    txtCubicle.setText("");     
    txtJackType.setEditable(false);
    txtJackType.setText("");        

    pnlTop.add(lblClosetLoc);
    pnlTop.add(txtClosetLoc);
    pnlTop.add(lblPhone1);
    pnlTop.add(txtPhone1);
    pnlTop.add(lblJackPaired);
    pnlTop.add(txtJackPaired);
    pnlTop.add(lblPhone2);
    pnlTop.add(txtPhone2);
    pnlTop.add(lblCubicle);
    pnlTop.add(txtCubicle);
    pnlTop.add(lblJackType);
    pnlTop.add(txtJackType);

    getContentPane().add(pnlTop);       

    setTitle("Test");
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    setLocation(300, 300);
    pack();
}

re-sizing textfields in GridLayout

basic property of GridLayout is that resize its child in both direction and fills / schrinks all available area came from its parent

Also is there a way to remove some of the padding after the labels?

pading are defined by .... 10, 10) in the pnlTop.setLayout(new GridLayout(3, 4, 10, 10));

I need some to be bigger or smaller. Is there a way to do this?

have to look at GridBagLayout or SpringLayout
