[news.eclipse.modeling.gmf] Re: property with File Browser Dialog 
Hi,

the problem is that in AdapterFactoryProvider#getPropertySource(Object object) - the object is value which was set for the feature but I need the feature to build PropertySource. Because if the feature was not set, I'll get null and will not be able to recognize if I have to use FileBrowser property source or not.

Hi, Atanas, I don't understand what you are asking:-( 

Maybe it will help if you describe a little more on what you have done,
and more specifically in which class/classes are the 2 methods below;
these methods are found all over the place so which one are you
referring to?.

Thanks Khai, I use your advise and now I can change Property Descriptors, but I have a problem because the object in

"IPropertySource getPropertySource(Object object)" represents value of property in sheet property page (for example object of type Integer or other depends of type value) and later in section :

"public IPropertyDescriptor[] getPropertyDescriptors() {
        ColorPropertyDescriptor descriptor;
        descriptor = new ColorPropertyDescriptor(object, PropertyName); ",

and I can not get the name of the property and category !!
I do not know how to do it.

Regards, Atanas.

This is a bit of a stretch because I haven't implemented any of this but
this is what I think you'd need to do for the GMF Properties View.

GMF uses tabbed sheets and sections... in your case specifically

org.eclipse.gmf.runtime.diagram.ui.properties.sections.AdvancedPropertySection 


It's this class that you would need to extend and override; the method
getPropertySourceProvider() is where you would return your custom
provider.

The rest of the information mentioned earlier in this thread should still be applicable.


Additionally you would have to override the contribution in the plugin.xml to use your 'custom' AdvancedPropertySection.

There is a thread in this same newsgroup under "Adding underline and strikethrough in appereance" where I'd posted some suggestions on how to
override the default contributions.


Hopes this help.

John,

That's sounds like a GMF question I don't know the answer to...

Hi Ed,

Thank you for the link. I tryed to use some of the solutions but it didn't help me very much.
For example:

The editor has this:

propertySheetPage.setPropertySourceProvider(new AdapterFactoryContentProvider(adapterFactory));

so you can override the the content provider to create a derived
property source:

   protected IPropertySource createPropertySource(Object object,
   IItemPropertySource itemPropertySource)
   {
     return new PropertySource(object, itemPropertySource);
   }

and you can override the property source to create a derived property
descriptor:

   protected IPropertyDescriptor
   createPropertyDescriptor(IItemPropertyDescriptor
   itemPropertyDescriptor)
   {
     return new PropertyDescriptor(object, itemPropertyDescriptor);
   }

And there you can implement whatever logic you want to produce
alternative cell editors in whatever situations they would be appropriate.



I change the propertySheetPage.setPropertySourceProviderto use my own class (new CustomAdapterFactoryContentProvider(adapterFactory));

But it's not called from Diagram. I noticed that GMF uses %Model%PropertyProvider extends GenericEMFPropertiesProvider

and only the addImagePropertyDescriptor {itemPropertyDescriptors.add(..)} from ItemProvider


and I don't know how to chnage that method to achieve the desired result
