Subject Re: PDPushButton Appearance

Thanks, it is working. Now I can see the button.
I need to understand this. I am a developer (java, c, .net, etc.) but I do
not know PDF format and I am new to PDFBox (used iText long ago).


The Javadocs states:

public void setNeedAppearances(Boolean
<http://download.oracle.com/javase/1.6.0/docs/api/java/lang/Boolean.html?is-external=true>
value)

Set the NeedAppearances value. *If this is false, *PDFBox will create
appearances for all field widget.


The javadoc does not say what happens if you set to TRUE.
You set to TRUE and the widget is visible, then I don't understand what
"appearances" is (and I think I don't understand differences between
appearances and widgets).
Also, the text field was already visibel (with border and background
colors).

Thanks again.
