深沉的船

JTextPane 网上说 它内置了 不能显示水平滚动条 没办法 只好看它的源码:



JTextPane 中 没找到相似的 JEditorPane 都是有相似的.



解决的办法如下:

把父类中的

 public boolean getScrollableTracksViewportWidth()
    {
        if(getParent() instanceof JViewport)
        {
            JViewport jviewport = (JViewport)getParent();
            TextUI textui = getUI();
            int i = jviewport.getWidth();
            Dimension dimension = textui.getMinimumSize(this);
            Dimension dimension1 = textui.getMaximumSize(this);
            if(i >= dimension.width && i <= dimension1.width)
                return true;
        }
        return false;
    }

public boolean getScrollableTracksViewportWidth()<br/> {<br/> if(getParent() instanceof JViewport)<br/> {<br/> JViewport jviewport = (JViewport)getParent();<br/> TextUI textui = getUI();<br/> int i = jviewport.getWidth();<br/> Dimension dimension = textui.getMinimumSize(this);<br/> Dimension dimension1 = textui.getMaximumSize(this);<br/> if(i >= dimension.width && i <= dimension1.width)<br/> return true;<br/> }<br/> return false;<br/> }<br/>
为

	@Override
	public boolean getScrollableTracksViewportWidth() {
		return false;
	}

@Override<br/> public boolean getScrollableTracksViewportWidth() {<br/> return false;<br/> }<br/>
就可以了.



另外有一种方法:

JTextPane pane = new JTextPane();

		pane.setContentType("text/html");

		JScrollPane scrollPane = new JScrollPane(pane);

		scrollPane.setHorizontalScrollBarPolicy(JScrollPane.HORIZONTAL_SCROLLBAR_AS_NEEDED);

		scrollPane.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED);

JTextPane pane = new JTextPane();<br/><br/> pane.setContentType("text/html");<br/><br/> JScrollPane scrollPane = new JScrollPane(pane);<br/><br/> scrollPane.setHorizontalScrollBarPolicy(JScrollPane.HORIZONTAL_SCROLLBAR_AS_NEEDED);<br/><br/> scrollPane.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED);<br/>
