Since there's no documentation for how to make a theme, using your own
stylesheets may be easier. What you can do is make a selection drop-down
like this:
<$select tiddler="SampleReveal1" default="set1" >
<option value="set1">Small Blue</option>
<option value="set2">Medium Red</option>
</$select>
Then you can make a stylesheet (regular tiddler tagged with
$:/tags/Stylesheet) like this:
\rules only filteredtranscludeinline transcludeinline macrodef
macrocallinline html
<$reveal type="match" state="SampleReveal1" text="set1">
.tc-tiddler-body h2 {
color: blue ;
font-size: 12px ;
}
</$reveal>
<$reveal type="match" state="SampleReveal1" text="set2">
.tc-tiddler-body h2 {
color: red ;
font-size: 24px ;
}
</$reveal>
I've used my own font/sizes/colors as an example, but you get the idea.
Getting back to your original question, if you were really set on changing
values inside the existing theme structure, you could do it in 2 steps. In
the first step, you select the group of styles you want from your
drop-down. A series of reveal widgets would then reveal a button. Inside
the button, you could use the action-setfield widget(s) to set as many
values as you wanted. You would then click on the button to invoke the
changes. So, 2 clicks/options from the users stand-point. The reason it
takes two steps is because you can't currently use the <$select> widget to
activate the action-setfield widget ... or at least I don't think you can.
Only the button widget can be used to send multiple messages at once.
Good luck!
