    Default [SOLVED] [newbie] The method GBC(int, int) is undefined for the type FontFrame

    Do you see the problem here? The method GBC.setInsets() exists.

    See error below.

    :confused:


    Java Code:
    [B]FontFrame.java[/B]
    package homenetwork.bkr.training;
    
    import java.awt.*;
    import java.awt.event.*;
    import javax.swing.*;
    
    @SuppressWarnings("serial")
    public class FontFrame extends JFrame {
    	
    	public FontFrame() {
    		setTitle("GridBagLayout Test");
    		setSize(DEFAULT_WIDTH, DEFAULT_HEIGHT);
    		
    		GridBagLayout layout = new GridBagLayout();
    		setLayout(layout);
    		
    		ActionListener listener = new FontAction();
    		
    		//construct components
    		@SuppressWarnings("unused")
    		JLabel faceLabel = new JLabel("Face :");
    		face = new JComboBox(new String[] {"Serif", "SansSerif", "Monospaced", "Dialog", "DialogInput"});
    		face.addActionListener(listener);
    		
    		@SuppressWarnings("unused")
    		JLabel sizeLabel = new JLabel("Size: ");
    		size = new JComboBox(new String[] {"8","10","12","15", "18", "24", "36", "48"});
    		
    		size.addActionListener(listener);
    		
    		bold = new JCheckBox("Bold");
    		bold.addActionListener(listener);
    		/* FIX */ 
    		sample = new JTextArea();
    		sample.setText("The quick brown fox jumps over the lazy dog.");
    		sample.setEditable(false);
    		sample.setLineWrap(true);
    		sample.setBorder(BorderFactory.createEtchedBorder());
    		
    		//add components to grid, using GBC convenience class 
    		add(faceLabel, new GBC(0,0).setAnchor(GBC.EAST));
    		add(face, new GBC(1,0).setAnchor(GBC.HORIZONTAL));
    		add(sizeLabel, new GBC(0,1).setAnchor(GBC.EAST));
    		add(size, new GBC(1,1).setFill(GBC.HORIZONTAL).setWeight(100,0).setInsets);
    		add(bold, new GBC(0,2,2,1).setAnchor(GBC.CENTER).setWeight(100,0).setInsets);
    		add(italic, new GBC(0,3,2,1).setAnchor(GBC.CENTER).setWeight(100,100));
    		add(sample, new GBC(2,0,1,4).setAnchor(GBC.BOTH).setWeight(100,100));
