Question

我有一个带有几个PanelDescriptors的向导迭代器。我试图在“下一步”时显示等待光标。单击一个实现WizardDescriptor.ValidatingPanel的PanelDescriptor。其中的validate（）方法需要时间执行。

到目前为止，我已经尝试过几种方法，但不适用于我。

            try {
                JFrame mainFrame = (JFrame) WindowManager.getDefault().getMainWindow();
                Component glassPane = mainFrame.getGlassPane();
                if (isWaiting) {
                    glassPane.setVisible(true);
                    glassPane.setCursor(Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR));
                } else {
                    glassPane.setVisible(false);
                    glassPane.setCursor(Cursor.getPredefinedCursor(Cursor.DEFAULT_CURSOR));
                }
            } catch (Exception e) {
                // probably not worth handling 
            }
        }
    });
}

try {            
    TopComponent.getRegistry().getActivated().setCursor(Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR));
    doBusyStuff();
} finally {
    TopComponent.getRegistry().getActivated().setCursor(Cursor.getDefaultCursor());
}

任何暗示我指向正确方向的提示都会受到赞赏。

试试这个

    private static final java.awt.event.MouseAdapter mouseAdapter = new java.awt.event.MouseAdapter() {

    };

    protected static final Cursor READY_CSR = new Cursor(Cursor.DEFAULT_CURSOR);
    protected static final Cursor WAIT_CSR  = new Cursor(Cursor.WAIT_CURSOR);

    public void setBusy(boolean busy) {

        if(busy) {
            setCursor(WAIT_CSR);
            frame.getGlassPane().setCursor(Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR));
            frame.getGlassPane().addMouseListener(mouseAdapter);
            frame.getGlassPane().setVisible(true);
        }else {
            setCursor(READY_CSR);
            frame.getGlassPane().setCursor(Cursor.getPredefinedCursor(Cursor.DEFAULT_CURSOR));
            frame.getGlassPane().removeMouseListener(mouseAdapter);
            frame.getGlassPane().setVisible(false);
        }
    }
