How to get Matisse GUI to show up my custom added components?

Question

I'm making my really first "graphic" program in Java and almost all the components I used were added by dragging them into the NetBeans GUI, that's okay.

However, I had to add some code into a new void outside the famous: initComponents() because I needed a JSlider which can interpret floats binded into a JTextField and viceversa, but that's not the main topic.

public AlbedoSection() {//Constructor
    initComponents();//Generated by the GUI mostly
    myInitComponents();//The void that I'm talking about 
                       //which adds a custom Slider with a TextField
                       //But doesnt show up in the GUI Editor
}

public void myInitComponents() {
    final DecimalFormat df = new DecimalFormat("0.####");
    //final JFrame frame = new JFrame();
    final JTextField text = new JTextField(20);
    final DoubleJSlider slider = new DoubleJSlider(0, 10000, 0, 100);
    slider.addChangeListener(new ChangeListener() {
        @Override
        public void stateChanged(ChangeEvent e) {
            text.setText(df.format(slider.getScaledValue()));
        }
    });
    text.addKeyListener(new KeyAdapter() {
        @Override
        public void keyReleased(KeyEvent ke) {
            String typed = text.getText();

            double value = Double.parseDouble(typed) * slider.scale;
            slider.setValue((int) value);
        }
    });
    slider.setBounds(700,450,200,30);
    text.setBounds(900,450,50,30);
    add(text); //adding textfield into the frame
    add(slider); // adding slider into the frame
}

I also set the components up and the program itsef works perfectly when I compile it, BUT the new "hardcoded" components doesn't seem to show up into the GUI Editor which led me to wonder If there's a way of doing that.

Forgive me If that's a stupid question, I'm just really new into programming.

So you're in essence asking why code *not shown* is not working, and this is ***very*** hard for us to answer. — Hovercraft Full Of Eels, Jun 06 '18 at 17:02
Please create and post your [mcve] with your question so we can see *and* run your code. Also do you understand how Swing layouts work? If not, perhaps study the tutorials for this as it may give you the answer. — Hovercraft Full Of Eels, Jun 06 '18 at 17:03
@HovercraftFullOfEels Sorry about that, I edited my post, hopefuly you can understand better what's my issue — RedEyedJealousy, Jun 06 '18 at 17:35
Yeah, you're not taking layout managers into consideration. Consider this: create a JPanel in NetBeans designer, give it a BorderLayout, add it to the main GUI, and then add your JSlider **to that JPanel**. — Hovercraft Full Of Eels, Jun 06 '18 at 20:58
and yes, read/study the layout manager tutorials. Google them. — Hovercraft Full Of Eels, Jun 06 '18 at 20:58
