SwingX 和 JToggleButton

发布于 2024-12-03 07:09:24 字数 128 浏览 3 评论 0原文

在我的应用程序中，我使用 SwingX 库中的 JXButton，我真的很喜欢画家方法。现在我必须将我的简单按钮更改为切换按钮，并为未选择/选择状态使用不同的画家。不幸的是我找不到 JXToggleButton。有没有办法保持画家方法的优势？

创建 JXType 组件实际上相当容易。您可能需要对边界、焦点等进行一些额外的检查。但这是您将采取的一般方法

public class JXToggleButton extends JToggleButton implements FocusListener, Paintable {
    private Painter<JTextField> backgroundPainter;
    private Painter<JTextField> foregroundPainter;

    public void setBackgroundPainter(Painter<JTextField> painter) {
        this.backgroundPainter = painter;
    }

    public void setForegroundPainter(Painter<JTextField> painter) {
        this.foregroundPainter = painter;
    }

    @Override
    protected void paintComponent(Graphics g) {

        if (backgroundPainter != null) {
            this.backgroundPainter.paint((Graphics2D) g, this, getWidth(), getHeight());
        }

        super.paintComponent(g);

        if (foregroundPainter != null) {
            foregroundtPainter.paint((Graphics2D) g, this, getWidth(), getHeight());
        }

    }
}

It's actually fairly easy to create a JXType component. You may need to do some extra checks for borders, focus, etc.. but this is the general approach you would take

public class JXToggleButton extends JToggleButton implements FocusListener, Paintable {
    private Painter<JTextField> backgroundPainter;
    private Painter<JTextField> foregroundPainter;

    public void setBackgroundPainter(Painter<JTextField> painter) {
        this.backgroundPainter = painter;
    }

    public void setForegroundPainter(Painter<JTextField> painter) {
        this.foregroundPainter = painter;
    }

    @Override
    protected void paintComponent(Graphics g) {

        if (backgroundPainter != null) {
            this.backgroundPainter.paint((Graphics2D) g, this, getWidth(), getHeight());
        }

        super.paintComponent(g);

        if (foregroundPainter != null) {
            foregroundtPainter.paint((Graphics2D) g, this, getWidth(), getHeight());
        }

    }
}
