将RTF加载到JTextPane中

Question

public class RichTextEditor extends TextEditorPane {

private final String extension = ".rtf";
private final String filetype = "text/richtext";

public RichTextEditor() {
    // super( null, "", "Untitled", null );
    super();
    // this.setContentType( "text/richtext" );
}

/**
 * Constructor for tabs with content.
 * 
 * @param stream
 * @param path
 * @param fileName
 * @param color
 */
public RichTextEditor( FileInputStream stream, String path, String fileName, Color color, boolean saveEligible ) {
    super( path, fileName, color, saveEligible );
    super.getScrollableTracksViewportWidth();
    //RTFEditorKit rtf = new RTFEditorKit();
    //this.setEditorKit( rtf );
    setEditor();
    this.read(stream, this.getDocument(), 0);
    //this.read( stream, "RTFEditorKit" );
    this.getDocument().putProperty( "file name", fileName );
}



private void setEditor() {
    this.setEditorKit( new RTFEditorKit() );

}

this.read(stream, this.getDocument(), 0);

JEditorPane类型中的read（InputStream,Document）方法不适用于参数（FileInputStream,Document,int）

为了能够访问编辑器工具包，您应该保留对它的引用。事实上，您的seteditor()方法的名称是setxxx，所以这应该是一个setter（事实上，我不认为您需要多次设置它，所以可能根本不应该存在这个方法）。定义字段：

private RTFEditorKit kit = new RTFEditorKit();

然后在构造函数中，

setEditorKit( kit );
kit.read(...);

如果坚持保留该方法，则其代码应为

kit = new RTFEditorKit();
setEditorKit( kit );
