如何在Java中的不同JPanel中使用滚动条显示不同的图像? [英] How to display different image with scroll bar in different JPanel in Java?

问题描述

我试图通过使用Java Swing窗口浏览对话框来在不同的Jpanel中显示两个图像.但是浏览第二张图像后，面板没有处于其位置.同样，没有滚动条的图像尺寸也会变大.我必须使用哪种类型的布局.每当浏览具有固定大小和滚动条的新布局时，都需要更改图像.请发表您的想法来帮助我.


我已经通过网格布局将一个面板分成了fout部分.我需要在顶部的两个部分中显示两个图像.
如果mge大小不同，则图像隐藏在面板内部.如果我使用滚动条，则无法对齐
正确地我应该使用哪种类型的布局.

推荐答案

将javax.swing.JPanel放在javax.swing.JScrollPane上，如下所示:

Put your javax.swing.JPanel on a javax.swing.JScrollPane like this:

JPanel pnlImage = new JPanel(new BorderLayout());
JScrollPane spnImage = new JScrollPane(pnlImage);

然后，不要将面板pnlImage放置在容器或框架上，而是将滚动窗格spnImage放置在容器或框架上.

Then instead of placing the panel pnlImage on your container or frame, place the scroll pane spnImage on it.

从上一个答案中，您得到了巨大的提示.使用ScrollPanel，所有内容都在面板上，并为您管理滚动.

From the previuous answer you were given a HUGE clue. Use a ScrollPanel, everything goes on the panel and it manages the scrolling for you.
