Question

I am using Netbeans gui, the fast easy drag and drop, lets say a created a JButton, named it “Start”, I added an event (ActionPerformed) for this JButton, so I get the following method

private void JButtonActionPerformed(java.awt.event.ActionEvent evt)     
{                                             
    // TODO add your handling code here:
}  

Then I added a JProgressBar, I want this progressbar to start when I click on this button, and be able to control its speed…etc..

Answer 1

You cannot directly set it’s speed, you just have to set it’s value. Read the docs for details. BTW JProgressBar is not really Netbeans specific, it is standard swing gui toolkit.
