Question

如何从JasperViewer中删除保存按钮？我发现了一种方法，但它来自JRViewer组件，我根本不相信。

Answer 1

我知道这已经过时了，但是在我开始工作之前我偶然发现了这一点，所以为了未来的研究人员，我将在这里展示对我有用的东西。

import javax.swing.JPanel;
import net.sf.jasperreports.engine.JasperPrint;
import net.sf.jasperreports.view.JasperViewer;

public class MyJasperViewer extends JasperViewer {

    public MyJasperViewer(JasperPrint jasperPrint, boolean isExitOnClose) {
        super(jasperPrint, isExitOnClose);

        try {
            ((JPanel) this.viewer.getComponent(0)).remove(0);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

现在就像这样使用它

JasperPrint jp = JasperFillManager.fillReport(url.openStream(), map, conn);

MyJasperViewer jv = new MyJasperViewer(jp, false);
jv.setVisible(true);

Answer 2

private void adjustViewerLayoutAndLookAndShow(JasperViewer viewer) {
    Container contentPane = viewer.getContentPane();
    JRViewerToolbar toolbar = (JRViewerToolbar) ((JRViewer)((JPanel)contentPane.getComponents()[0]).getComponent(0)).getComponent(0);

    JButton btnSave = (JButton) toolbar.getComponent(0);
    btnSave.setEnabled(false);

    JButton btnPrint = (JButton) toolbar.getComponent(1);
    btnSave.setEnabled(false);


    viewer.setTitle(extraInfo);
    viewer.setVisible(true);
}

从JasperViewer中删除或禁用保存按钮
