JProgressBar没有正确显示

Question

I am attempting to use a JProgressBar as a health bar for a simple game. I am trying to get it to be full and visible to start the program. This is my code for the JProgressBar:

    progressBar = new JProgressBar();
    progressBar.setMinimum(0);
    progressBar.setMaximum(model.user.getTotalHp());
    progressBar.setValue(model.user.getTotalHp());
    progressBar.setForeground(Color.GREEN);
    progressBar.setString(model.user.getHp() + "/" + model.user.getTotalHp());
    progressBar.setBounds(450 + insets.left, 370 + insets.top,
             size.width+40, size.height + 45);
    add(progressBar);

This is the result: https://gyazo.com/4e6fc1879597ba67495bda183dbbf212 What am I doing wrong, it's not full, green, or have the String inside.

Answer 1

The string isn't painting because you need to call this first:

progressBar.setStringPainted(true);

I used the following code and the progress bar renders fine:

JFrame frame = new JFrame("test");
JProgressBar progressBar = new JProgressBar();
progressBar.setMinimum(0);
progressBar.setMaximum(100);
progressBar.setValue(50);
progressBar.setForeground(Color.GREEN);
progressBar.setString("50/100");
progressBar.setStringPainted(true);
frame.add(progressBar);
frame.setVisible(true);

Maybe your total is coming out as 0 or maybe a float being rounded to 0.
