Toggle buttons working with set values
Basically, I wanted to make a few toggle buttons to show me the status of certain classes in my package. Enabled/disabled, if I click them it'd enable/disable dependent on the status of the class.

However, I noticed that it would only accept variables as a value to toggle on/off. What I'd really like to do is have the value (The variable field.) be possible to reference things such as %class(test) etc. So, instead of having the button check on the class, I had to go for something like:

<window name="Aetolia" usesession="false">
  <packages>English Directions|Aetolia</packages>
  <class name="Test" enabled="false" id="1066"/>
  <button type="Toggle" variable="@test_status" priority="10670" id="1067">
    <caption>Test on</caption>
    <state caption="Test off"></state>
  <alias name="teston" id="1069">
    <value>#T+ test
#VARIABLE test_status %class(test)</value>
  <alias name="testoff" id="1070">
    <value>#T- test
#VARIABLE test_status %class(test)</value>
  <var name="test_status" usedef="true" id="1071">0</var>

So! If there's a better way of doing it, I'd be appreciative of any pointers. I'd also suggest being able to use certain things in a button, rather than variables. %class, %pref, etc. Not sure how possible this is, though.

You have the right idea.
The problem with using functions in the button state or expression boxes is that the state of a predefined function never changes.
If Zugg were to make the buttons evaluate the functions things can slow WAY down. Besides handling this yourself is pretty easy.
<?xml version="1.0" encoding="ISO-8859-1" ?>
  <class name="ClassStates">
    <button type="Toggle" variable="@ClassStates.Test" priority="10670">
      <caption>Test is Off</caption>
      <value>#call @class(Test,1)</value>
      <state caption="Test is On">#call @class(Test,0)</state>
    <var name="ClassStates" type="Record">Test=0</var>
    <func name="Class">
      <value>#if (%null($newState)) {#Return %class($name)}
#switch ($newState)
 (0) {
      #T- $name
      #addkey ClassStates $name 0
 (1) {
      #T+ $name
      #addkey ClassStates $name 1
#Return {%class($name)}</value>
  <class name="Test" enabled="false"/>

The above code creates the following.
    A class named Test
    A class named ClassStates
    A Button within ClassStates
    A database variable within ClassStates named ClassStates
    A function within ClassStates named Class.

The button is controlled by the value of the key test in the ClassStates variable.

To test things out type '#call @class(Test,1)', '#call @class(Test,0)', or '#show The class Test is in the @class(Test) state.' into the command line.
Clicking the button also turns on or off the Test class.
