BooleanValue/IntegerValue [message #663924]

Ok... Last question for now I promise...

Looking at the docs, I'm trying to figure out how to implement a Boolean property that uses option buttons to offer true or false in the UI.

I found the discussion of Value Properties in the doc and saw that I should be able to define a BooleanValue something like this example of how to use the IntegerValue:

@Label( standard = "age" )
@NonNullValue
ValueProperty PROP_AGE = new ValueProperty( TYPE, "Age" );
IntegerValue getAge();
void setAge( String age );
void setAge( Integer age );

Just one problem... IntegerValue doesn't seem to exist. Neither does BooleanValue. Is there another example that I can refer to?

Konstantin - I know I saw you do something similar to this in the brief demo you did for me at EclipseCon, but can't seem to find an example that does the same thing.

Any and all help is greatly appreciated.

Thanks!

Along the same lines, I see that Boolean properties are rendered in the UI as a checkbox with the checkbox part on the left and the label on the right. Is there a "hint" to suggest that the checkbox should be to the right of the label?

The doc must be out of date. Here is how you would write your example:

@Type( base = Integer.class )
@Label( standard = "age" )
@NonNullValue
ValueProperty PROP_AGE = new ValueProperty( TYPE, "Age" );
Value<Integer> getAge();
void setAge( String age );
void setAge( Integer age );

If you grab the Sapphire samples project, the gallery sample has quite a bit of usage of different data types.

There is an open enhancement request for that:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=329068

Right now, we only support the native "label on the right" style of checkboxes, but you can choose if you it should be aligned on first column or the second column.

To get it to align on the second column, create a composite part, set "indent" property on the composite" and place the boolean property editor inside the composite.
