e803. 获得和设置JProgressBar的值

  // To create a progress bar, see e801 创建一个JProgressBar组件
    
    // Get the current value
    int value = progress.getValue();
    
    // Get the minimum value
    int min = progress.getMinimum();
    
    // Get the maximum value
    int max = progress.getMaximum();
    
    
    // Change the minimum value
    int newMin = 0;
    progress.setMinimum(newMin);
    
    // Change the maximum value
    int newMax = 256;
    progress.setMaximum(newMax);
    
    // Set the value; the new value will be forced into the bar's range
    int newValue = 33;
    progress.setValue(newValue);

It is also possible to set all the values at once by using the model:

    progress.getModel().setRangeProperties(newValue, 0, newMin, newMax, false);
