Question

je ne peux pas mettre txt en ligne et img dans un JEditorPane

Image de JEditorPane:

comment puis-je les mettre en ligne?

Ceci est mon code:

 JFrame frame = new JFrame("HelloWorldSwing"); 

     frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
     GridBagLayout gridBagLayout = new GridBagLayout(); 
     gridBagLayout.columnWidths = new int[]{363, 0}; 
     gridBagLayout.rowHeights = new int[]{261, 0, 0}; 
     gridBagLayout.columnWeights = new double[]{0.0, Double.MIN_VALUE}; 
     gridBagLayout.rowWeights = new double[]{0.0, 0.0, Double.MIN_VALUE}; 
     frame.getContentPane().setLayout(gridBagLayout); 


     JEditorPane jep = new JEditorPane(); 
     jep.setContentType("text/html"); 

     HTMLEditorKit kit = new HTMLEditorKit(); 
     jep.setEditorKit(kit); 


     StyleSheet styleSheet = kit.getStyleSheet(); 
     styleSheet.addRule("body {color:#000; font-family:times; margin: 4px; display: inline; line-height: 20px;}"); 
     styleSheet.addRule("img {padding-top: 10;}"); 


     jep.setText("<span>Hello computer! <img src='file:ClientServer/Sticker/1.png' width='20' height='20' valign='middle'></span>");

• javax/swing/text/html/ImageView.java

/** 
* Update any cached values that come from attributes. 
*/ 
protected void setPropertiesFromAttributes() { 
    StyleSheet sheet = getStyleSheet(); 
    this.attr = sheet.getViewAttributes(this); 

    //... 

    AttributeSet attr = getElement().getAttributes(); 

    // Alignment. 
    // PENDING: This needs to be changed to support the CSS versions 
    // when conversion from ALIGN to VERTICAL_ALIGN is complete. 
    Object alignment = attr.getAttribute(HTML.Attribute.ALIGN); 

    vAlign = 1.0f; 
    if (alignment != null) { 
     alignment = alignment.toString(); 
     if ("top".equals(alignment)) { 
      vAlign = 0f; 
     } 
     else if ("middle".equals(alignment)) { 
      vAlign = .5f; 
     } 
    } 

• En se référant au code ci-dessus, en spécifiant "align" au lieu de "valign" ne semble pas fonctionner correctement .
  • styleSheet.addRule("img {padding-top: 10; align: middle; valign: middle; vertical-align: middle; }");

Ce qui suit est un exemple de substituant la méthode ImageView#getAlignment(...).

public class ImgBaselineTest { 
    private JComponent makeUI() { 
    JEditorPane editor2 = makeEditorPane(new ImgBaselineHTMLEditorKit()); 
    JEditorPane editor1 = makeEditorPane(new HTMLEditorKit()); 
    JPanel p = new JPanel(new GridLayout(2, 1)); 
    p.add(new JScrollPane(editor1)); 
    p.add(new JScrollPane(editor2)); 
    return p; 
    } 
    private JEditorPane makeEditorPane(HTMLEditorKit kit) { 
    JEditorPane jep = new JEditorPane(); 
    jep.setContentType("text/html"); 
    jep.putClientProperty(JEditorPane.HONOR_DISPLAY_PROPERTIES, Boolean.TRUE); 
    // HTMLEditorKit kit = new HTMLEditorKit(); 
    // HTMLEditorKit kit = new ImgBaselineHTMLEditorKit(); 
    jep.setEditorKit(kit); 
    StyleSheet styleSheet = kit.getStyleSheet(); 
    styleSheet.addRule("span {color:orange; font-family:times; margin: 4px; display: inline; line-height: 20px;}"); 
    styleSheet.addRule("img {padding-top: 10; align: middle; valign: middle; vertical-align: middle; }"); 

    //URL url = ImgBaselineTest.class.getResource("16x16.png"); 
    String url = "https://i.stack.imgur.com/MOQoc.png"; 
    // jep.setText("<span>Hello computer! <img src='" + url + "' width='20' height='20' valign='middle'></span>");

    return jep; 
    }

    EventQueue.invokeLater(() -> {

     f.setSize(320, 240); 
     f.setLocationRelativeTo(null); 
     f.setVisible(true); 
    }); 
    } 
}

    @Override public ViewFactory getViewFactory() { 
    return new HTMLEditorKit.HTMLFactory() { 
     @Override public View create(Element elem) { 
     View view = super.create(elem); 
     if (view instanceof LabelView) { 
      System.out.println(view.getAlignment(View.Y_AXIS)); 
     } 
     AttributeSet attrs = elem.getAttributes(); 
     Object elementName = attrs.getAttribute(AbstractDocument.ElementNameAttribute); 
     Object o = elementName != null ? null : attrs.getAttribute(StyleConstants.NameAttribute); 
     if (o instanceof HTML.Tag) { 
      HTML.Tag kind = (HTML.Tag) o; 
      if (kind == HTML.Tag.IMG) { 
      return new ImageView(elem) { 
       @Override public float getAlignment(int axis) { 
       switch (axis) { 
       case View.Y_AXIS: 
        return .8125f; // magic number... 
       default: 
        return super.getAlignment(axis); 
       } 
       } 
      }; 
      } 
     } 
     return view; 
     } 
    }; 
    } 
}
