Hello all,
I would like to know whether it is possible to programmatically add a few
property-entries to the property-view, when selecting an element in my
GMF-generated editor. I read some of the posts about this subject, but they
where not very clear to me.
( http://dev.eclipse.org/newslists/news.eclipse.modeling.gmf/m sg00890.html)
What is the first step in order to have propertyProviders actually present
in my generated editor? At the moment I don't see any classes for me to
override with my own custom behaviour. I basically want to add some
properties to the property-view bases on a selection made in the editor.
This information has to come from code outside the generated editor, so
therefore I need to implement this programatically, and not using the
genmodel (I think?).
But where is the place to cut in-between the code of GMF, in order to
deliver a specialised PropertyProvider ?
Does anyone have any experience with this?
Kind regards,
Martin

To maybe answer my own question:
I''ve achieved this behaviour by overriding : PropertySource , being created
in : diagram.sheet.YourAPPPropertySection (getPropertySource(Object
object)). Here I have overridden the getPropertyDescriptors and
getPropertyValue to respond to my own inserted PropertyDescriptor.
To check if the right element is selected, the 'object' object can be used
to check which element it is.
I think i'm sticking to my own sollution, unless ofcourse it is very very
evil :-D

Martin

To display the custom property-view i've did the following:
- In the .diagram.sheet.youAPPPropertySection i've changed the
getPropertySource(Object object) method to use my custom PropertySource
class
- I've overwritten myPropertySource extending PropertySource, and
implemented the getPropertyDescriptors and getPropertyValue functions.
- These two functions add my own PropertyDescriptor , and respond to a
requiest on this descriptor.
I think it works ok.
I can even check the kind of element which is requisting the properties by
checking the class of the 'object' object.
I will stick to this, unless it is very very evil to do it in this way :-D

Martin

Martin,
Typically you'd do this directly in the generated EMF.Edit item
providers so your changes would be specific to each type of object and
would appear in all editors based on them. Not sure if that applies for
GMF, but I think it does...
