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);
