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:
| Code: |
<window name="Aetolia" usesession="false">
<uid>{FE71CB01-8573-4BEE-BD20-2A74E960FD86}</uid>
<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>
</button>
<alias name="teston" id="1069">
<value>#T+ test
#VARIABLE test_status %class(test)</value>
</alias>
<alias name="testoff" id="1070">
<value>#T- test
#VARIABLE test_status %class(test)</value>
</alias>
<var name="test_status" usedef="true" id="1071">0</var>
</window> |
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.
| Code: |
<?xml version="1.0" encoding="ISO-8859-1" ?>
<cmud>
<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>
</button>
<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>
<arglist>$name,$newState</arglist>
</func>
</class>
<class name="Test" enabled="false"/>
</cmud> |
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. |
