JScrollBar

 Here are the steps to use JScrollBar in NetBeans with a GUI project:

---

✅ Step-by-Step in NetBeans GUI Builder:

🎯 1. Create a New Project

• Open NetBeans.

• Go to File > New Project.

• Choose Java > Java Application.

• Click Next, name the project, and click Finish.

---

🎯 2. Create a JFrame Form

• Right-click the Source Packages > your package.

• Select New > JFrame Form.

• Name it (e.g., ScrollBarExample), and click Finish.

---

🎯 3. Add Components via Drag and Drop

• Open ScrollBarExample.java in Design view.

• From the Palette, drag:

  • A JLabel to display the value (e.g., jLabel1)

  • A JScrollBar (found under Swing Controls)

---

🎯 4. Configure the ScrollBar

• Click on the JScrollBar (e.g., jScrollBar1)

• In Properties window, set:

  • orientation = HORIZONTAL

  • minimum = 0

  • maximum = 100

  • value = 0

  • unitIncrement = 1

  • blockIncrement = 10

---

🎯 5. Write Logic to Handle Scroll

• Switch to Source view.

• Find the scrollbar event (click on the scrollbar, then in Events > adjustmentValueChanged).

Add the following code inside the event:

private void jScrollBar1AdjustmentValueChanged(java.awt.event.AdjustmentEvent evt) {
    int val = jScrollBar1.getValue();
    jLabel1.setText("Scroll value: " + val);
}

---

🎯 6. Run the Project

• Right-click your JFrame file > Run File.

• You should see a horizontal scrollbar that updates the label as you scroll.

---

🔁 Optional:

To scroll another component (like an image or text area), you may want to use a JScrollPane instead — let me know if you want steps for that too.
