    Default How do you apply GridBagLayout constraints to existing controls

    I use the GUI builder of NetBeans and put a panel on a frame and controls on the panel.
    How do I then apply GridBagLayout to these controls?
    I have tried re-adding the control to the panel in code but in this example changing the x,y to anything other than 0,0 makes my label disappear.
        public MyFrame() {           // constructor 
        private void InitInputPanel(){
            JPanel p = this.InputPanel; 
            GridBagLayout gbl = new GridBagLayout();
            GridBagConstraints gbc = new GridBagConstraints();
            gbc.gridwidth = 11;
            gbc.gridheight = 84;
            gbc.gridx = 1;
            gbc.gridy = 80;
            p.add(this.lblCustomerName, gbc);
    I found lots of help using GridBagLayout and all of them build the control in code and add it to the frame.
    How do I use GridBagLayout with already placed controls?

    Default Re: How do you apply GridBagLayout constraints to existing controls

    My little experience with having NetBeans build any GUI is that it is very difficult to make any changes to that GUI yourself.
    Any changes to the NetBeans GUI must be done using NetBeans.
    If you don't understand my answer, don't ignore it, ask a question.
