Here is some code snippet for the if-else syntax in sdef file:<if>
<condition><class>ColumnScaleCondition</class></condition>
<then>
<property-editor>Scale</property-editor>
</then>
</if>And here is the ColumnScaleCondition class:public final class ColumnScaleConditionextends SapphireModelCondition
{
@Override
public boolean evaluate()
{....
}@Override
public List<String> getDependencies()
{
return Collections.singletonList( IColumnDescriptor.PROP_TYPE.getName() );
}
}Make sure you import the package of your condition class in the sdef file:<import>
<package>...</package>
</import>

I couldn't extract the correct syntax for if-else block, can you please give an example XML section on sdef file to achieve if else.
Thanks,

Thanks Konstantin,
Can you please point me to some examples for @PropertyListeners implementation?

We don’t support this yet. Please open an enhancement request. Another approach to dealing with a lot of content is to break it up among multiple nodes in the content outline. For instance, you could have an Advanced node beneath your main node rather than a collapsible Advanced section.

We have two ways of presenting multi-select lists: a slush bucket and a checkbox list. I suppose I can see how I horizontal arrangement of checkboxes could also be useful, especially if you know that the set of possible values is small, such as with some enums. Please open an enhancement request.

Enablement does not clear content. To clear content, you can use @PropertyListeners annotation to register listeners on your controlling properties. The listener will be called when property changes and can reach out and clear related properties as necessary. I suppose you could also register a listener on the property that needs clearing and look at the property’s enablement state instead. Such a listener could be written generically and then attached to any number of properties. Hmm… that makes me wonder if we should consider supporting this scenario out of the box. I can certainly see value of a @ClearOnDisable annotation. Maybe go ahead and open an enhancement request for this too.
> 4. Hide
You can use the if-else sdef construct to control what is shown based on the condition that you specify. We don’t have many examples of this in samples right now. The only one I found is in DefinitionEditor.sdef from the sapphire.sdk plugin.
The condition class that is used with if-else construct is “live” in that it can update itself. The UI listens on condition changing and acts accordingly. Take a look at SapphireModelCondition class which is a good base class for conditions that need to react to changes in the model.
Note that you can also use conditions to hide content outline nodes. There is a property in the node’s definition that accepts a “visible-when” condition.

Subject: Sapphire Query on Section, Multi List, Enablement
Hi Konstantin,
Sorry to bother you again, I have few more queries.
I assure you, I will put those communications back in forum once it back alive for wider audience. please help on email till then.
1. Section - Expand/Collapse
- I add a section in the sdef like 'Advanced Options', I want this to be collopsed by default, when required user can expand and fill in details. Is there a <hint> available for this?
2. Multiple Chose values arranged horizontally
- I have a property which will accept multiple choice of comma seprated values, is there a way I can arrange the options as check box horizontally. Currently the examples are having only slash bucket, which occupies more screen space than what we want
Example:
Property: Option1 Option2 Option3 (Check boxes)
3. Enablement
One of the problem I am seeing with Enablement annotation,
<item1>
<item2>
<item3>
I defined <item2> and <item3> are enabled only when <item1> set to a particular value. Lets say user first time select that value in <item1> and set required property in <item2> and <item3>. when he goes back to <item1> and changes its value. <item2> and <item3> are disabled as expected but the values previously entered in the XML is not going away. How do we remove those value from xml when we disable that field?
4. Hide
I have seen the example to hide some additional property based on a selection (in Contact, IAssistance). But it works only the sub properties like
<selection>
<option1>
<option2>
</selection>
<option1> and <option2> can be hidden and shown based on the selection.
Is there a way I can hide the UI of non sub properties like
<item1>
<item2>
<item3>
if <item1> set to particular value <item2> and <item3> should be removed.
Thanks,
-Naga
