任何人都可以给出示例代码或链接,以了解如何在Swing应用程序中将JProgressbar绑定到bean类的属性吗?

最佳答案

您可以使用JGoodies Binding将进度条绑定到模型。但是,您的(view-)模型必须触发属性更改事件才能起作用。
http://www.jgoodies.com/downloads/libraries.html我可以在星期一发布示例代码。

例:

在您的ViewModel中:

private final PropertyChangeSupport changeSupport = new PropertyChangeSupport(this);

private int progress;

public void addPropertyChangeListener(PropertyChangeListener listener)
{
    changeSupport.addPropertyChangeListener(listener);
}

public void removePropertyChangeListener(PropertyChangeListener listener)
{
    changeSupport.removePropertyChangeListener(listener);
}

public int getProgress()
{
    return progress;
}

public static final String PROPERTY_PROGRESS = "progress";

public void setProgress(int progress)
{
    int old = this.progress;
    this.progress = progress;
    changeSupport.firePropertyChange(PROPERTY_PROGRESS, old, progress);
}


在您看来:

BeanAdapter<ViewModel> beanAdapter = new BeanAdapter<ViewModel>(viewModel, true);
Bindings.bind(progressBar, "value", beanAdapter.getValueModel(ViewModel.PROPERTY_PROGRESS));
