Is it possible to have the CSS command-button invoke a user-written
macro command?
Sure. This has always worked.
Note that in XXE, there is no differences in terms of access between a
command written in Java and a macro command. Both are found in the same
global command registry.
Reference:
http://www.xmlmind.com/xmleditor/_distrib/doc/csssupport/command-button.html
On elements which contain an IDREF attribute, we'd like to have a
drop-down-arrow on the element which, when the user clicks on it,
invokes one of our custom macros (which creates a pick list of the
appropriate set of IDs for that particular element).
For example, we have IDs for things like reference works, sections,
chapters, examples, index items, etc., etc. We have specific elements
to refer to each one of these so that the user does not have to wade
through a large set of irrelevant IDs. For example, for citations to
referenced works, we have a citation element. When a user inserts a
citation element and invokes our custom macro command (called
'SetReference'), that command displays a pick list of the works in the
master list of references. It does not show any other elements with an
ID, only those that are relevant to a 'citation'.
I've tried to use the command-button to refer to our macro, but it does
not work (which is no great surprise since the documentation says the
command must be one in Chapter 6 of the command documentation).
I don't see why. Probably a very minor problem.
But it would be nice if something like this
command-button(icon, icon(pop-down), color, black, command, "SetReference")
Good idea to quote "SetReference" because in CSS, identifiers are
case-insensitive. Without the quotes, XXE would have looked for a
command called setreference.
would invoke our macro.
As I think you know, we are way back on version 5.3.0 of XXE. So if
this is now available in newer versions and I failed to notice, then
please forgive me for asking. But if there is a way, then I'd really
like to know.
It should work find in v5.3 too, because the feature you need has worked
since the inception of command-button().
Real example used in the configuration found in the add-on called "Easy
Profiling":
Excerpts from profiling.css:
---
@property-value value-footer(setStyleIcon)
" "
command-button(icon, setStyleIcon, tool-tip, _("Set style"),
command, "{prf}setStyle", parameter, "style")
buttons(#808080);
value[style]:after {
content: value-footer(url(has_style.png));
}

(@property-value is just a simple CSS macro facility. See
http://www.xmlmind.com/xmleditor/_distrib/doc/csssupport/prop-group-value.html)
Excerpts from profiling.xxe:
---
<command name="{prf}setStyle">
<macro>
<sequence>
<command name="editAttribute" parameter="%0" />
<set variable="style" expression="%_" plainString="true" />
<choice>
<sequence>
<test expression="not($style)" />
<command name="removeAttribute" parameter="%0" />
</sequence>
<sequence>
<get
expression="replace($style,"'","\\'",l)" />
<command name="putAttribute" parameter="%0 '%_'" />
</sequence>
</choice>
</sequence>
</macro>
</command>
