@Daisuke – there is no append method (by this or any other name) that I know of.

To list a Java object’s methods, you can use the builtin methods or methodsview functions, or one of my utilities: uiinspect or checkClass.

jEditbox.append(new_text);

Would this be possible?
Another question: Since I don’t know Java, I have no clue about what kind of member functions are available. How can one know that?

@Carsten – it should work, you’re probably doing something wrong. Perhaps you are updating the wrong handle, or updating the editbox’s contents via Matlab not Java (this resets the Java customizations).

is there a way to get rid of the vertical scrollbar? I tried to do so using

jScrollPane.setVerticalScrollBarPolicy(javax.swing.JScrollPane.VERTICAL_SCROLLBAR_NEVER)

but this has no effect.

Thanks,
Carsten

@Holger – this is probably related to the fact thar R2013b started using Java 7, which is a major overhaul over the previous Java 6. I assume that this broke some functionality of the editbox. Since the underlying Java control is a standard JTextPane, you can easily search the net for relevant reports of (and possible workarounds for) this issue. Let us know if you find something relevant.

After getting some feedback on stackexchange, I have a way to dramatically improve performance. Instead of performing getText and setText, you can insert the new HTML at the end of the document in the following way

function logMessage(jEditbox, text)
text = [text ''];

% Place the HTML message segment at the bottom of the editbox
Doc = jEditbox.getDocument();
jEditbox.getEditorKit().read(java.io.StringReader(text), Doc, Doc.getLength());
jEditbox.setCaretPosition(Doc.getLength());
end

I was using this for some time (from older posts).
But in R2013b (all prior versions work), the hyperlink feature broke. Not completely, but the mouse cursor doesn’t change to a hand when hovering over a hyperlink.

In addition the following code also does nothing:

jHelpLinkButton = java(findjobj(hButton));
jHelpLinkButton.setCursor(java.awt.Cursor.getPredefinedCursor(java.awt.Cursor.HAND_CURSOR));

When using a “com.mathworks.widgets.HyperlinkTextLabel” (from your book), also the hand cursor doesn’t appear, but at least, the label changes color when hovering.

Any idea, how I can get this working again?
An acceptable workaround would be to change the hyperlink style, so it has an alternate color when hovering over it. But I think I would have to change the default style for hyperlinks in the HTMLEditorKit…
