I have in Java two panels which need to have same layout, there is my functions for initializations panels. 
private void InitializePanelCom(){
        pnlCom=new JPanel();
        pnlCom.setSize(300,160);
        pnlCom.setLocation(10, 60);
        add(pnlCom);
        GridBagLayout gb=new GridBagLayout();
        GridBagConstraints gc=new GridBagConstraints();
        pnlCom.setLayout(gb);
        jLabelcommPort = setJLabel("Com Port : ");
        jLabelbaudRate = setJLabel("Baud Rate : ");
        jLabelplcAddress = setJLabel("Plc Address : ");
        jLabelsendTime = setJLabel("Send Time : ");
        jLabelx50 = setJLabel(" x 50 ms (2 - 99)");
        jComboBoxcommPort = setJComboBox(commPortList);
        jComboBoxbaudRate = setJComboBox(bitRateList);
        jTextAreaPlcAddress = setJTextField("");
        jTextAreaSendTime = setJTextField("");
        gc.insets = new Insets(10,0,0,0);
        gc.ipadx = 120; 
        gc.weightx = 1;
        gc.gridx = 0;
        gc.gridy = 0;
        gc.anchor=GridBagConstraints.EAST;
        pnlCom.add(jLabelcommPort,gc);
        gc.insets = new Insets(10,0,0,0);

Problem is that second panel (initializetcp, second picture doesn't look the same, labels are moved at left , it is different ). Can anybody help, I am new with GridBagContsraints at all ?
