Dear developers,
i like to connect objects to the properties view.
When i select an object (with the Mouse etc.) the attributes (changes allowed) should appear in the view . I know i have to implement IPropertySource but i don't know how i can connect it to the properties view.

Thanks in advance

Marcel,

EMF's generated editors do it like this:

public Object getAdapter(Class key)
{
if (key.equals(IContentOutlinePage.class))
{
return getContentOutlinePage();
}
* else if (key.equals(IPropertySheetPage.class))**
{
return getPropertySheetPage();
}*
else if (key.equals(IGotoMarker.class))
{
return this;
}
else
{
return super.getAdapter(key);
}
}

public IPropertySheetPage getPropertySheetPage()
{
if (propertySheetPage == null)
{
propertySheetPage =
new ExtendedPropertySheetPage(editingDomain)
{
public void setSelectionToViewer(List selection)
{
EcoreEditor.this.setSelectionToViewer(selection);
EcoreEditor.this.setFocus();
}

public void setActionBars(IActionBars actionBars)
{
super.setActionBars(actionBars);
getActionBarContributor().shareGlobalActions(this,
actionBars);
}
};
* propertySheetPage.setPropertySourceProvider(new
AdapterFactoryContentProvider(adapterFactory));*
}

return propertySheetPage;
}

If you don't need a special (your own) property sheet page, then all you
need to do is for your selected object (these are the objects that show
up in your editor/view as the ISelection) needs to implement IAdaptable
and do:

public Object getAdapter(Class key) {
if (key == IPropertySource.class) {
return new YourPropertySource(this);
} else
...
}

This will then work with the default property sheet page if you don't
require any special processing other than what IPropertySource can do.

Your class needs to implement IAdaptable, and you have to provide a mechanism that when asked for an instance of IPRopertySource, that you return an implementation that can connect you. Often, it will look like:

public MyClass implements Adaptable, IPropertySource {
  public Object getAdapter(Class clazz) {
    if (clazz == IPropertySource.class) {
       return this;
    }
    return null;
  }
}

However, your class doesn't have to implement IPropertySource. It can return another class (say, an anonymous or named inner class) that does the work.

Ultimately it boils down to calls in the IPropertySource that look like getObject(String property) or some such. You just need to have a nested if looking for the name of the property and converting it into a real value.
