Hi Hussein,
I've come up with a cheat to accomplish my desired ability to set node trees as
readonly using css. You may be able to tell me whether this is inadvisable or
na?ve. I think perhaps it is at least a bit na?ve in that it assumes the
context node is an alement, so it wouldn't work for comments or attibutes. With
a bit more time I could probably solve that. I created a stylesheet extension
that looks like this:
package com.pgs.xxe.css;
import com.xmlmind.xmledit.doc.Element;
import com.xmlmind.xmledit.doc.Node;
import com.xmlmind.xmledit.styledview.StyledViewFactory;
import com.xmlmind.xmledit.stylesheet.StyleSpecsBase;
import com.xmlmind.xmledit.stylesheet.StyleValue;
public class StyleSheetExtension extends StyleSpecsBase {
public StyleSheetExtension(String[]args, StyledViewFactory
styledviewfactory) {
}
public StyleValue readonly(StyleValue[] args, Node contextNode,
StyledViewFactory viewFactory) {
Element element = (Element) contextNode;
element.setReadOnly(true);
return null;
}
}
And I created a css rule that looks like this:
content: invoke("readonly");
Because the readonly method returns a null StyleValue, it has no effect on the
element content. As far as I can tell it's working, but it seems so simple that
it couldn't possibly be covering everything, could it?
Regards,
Matt

You can do many things. This is how the form controls -- see
XXE_install_dir/demo/form-sampler.xml --
Slightly edited excerpt of
XXE_install_dir/demo/form-sampler/form-sampler.css:
---
rgb2 {
content: gadget("com.xmlmind.xmledit.form.ComboBox",
labels, "Green\A Blue\A Red",
values, "green\A blue\A red"); }
---
(http://www.xmlmind.com/xmleditor/_distrib/doc/csssupport/gadget.html)
and the support of MathML have been implemented.
Slightly edited excerpt of MathML_addon_install_dir/common/mathml.css:
---
mml|msqrt {
/* Block-like */
display: view("com.xmlmind.xmleditext.mathml.MathElementViewFactory");
}
---
However the most advanced techniques are not documented. For now, you just have:
---
smiley {
content: component("Smiley");
font: normal normal small sans-serif;
/* Needed to display the red border of the selection */
display: inline-block;
padding: 1px;
}
---
That is, you can replace the normal view of a styled element by a custom
component.
See "XMLmind XML Editor - Developer's Guide", "Active custom views:
specialized editors embedded in the DocumentView"
