Hello,
Do you use the property sheet entry provided by GEF =
(UndoablePropertySheetEntry) ?
Don't ask me what it is, I don't know, but the result is all the model =
modifications you do through the properties view will be embedded in a =
Command and executed through the CommandStack.
So, as a result:
- the editor dirty state should update when you change smthg in the =
properties view,
- all the modifications done through the properties view should be =
undoable,
- when you change smthg in the model (with Command & CommandStack), if t=
he =
properties view is opened, it should update to reflect the change.
Here is the code to add in the editor class:
private PropertySheetPage propPage;
public Object getAdapter(Class aClass)
{
...
else if (aClass =3D=3D IPropertySheetPage.class)
return getPropertySheetPage();
...
}
public PropertySheetPage getPropertySheetPage()
{
if (propPage =3D=3D null)
{
propPage =3D new PropertySheetPage();
propPage.setRootEntry(GEFPlugin.createUndoablePropertySheetE ntry(getCo=
mmandStack()));
}
return propPage;
}
also, make sure the isDirty method is properly (I don't know if this is =
=
really "properly" but it works) implemented:
public boolean isDirty()
{
return getCommandStack().isDirty();
}
Hope this will help,

Thanks for your answer!
In my editor , getAdapter() implemented liked below:
public Object getAdapter(Class type) {
if (type == IContentOutlinePage.class)
return getOutlinePage();
return super.getAdapter(type);
}
The method super.getAdapter(type) had done many works include your
mentioned in eclipse 2.1.3. But PropertySheetEntry had been called
insted of UndoablePropertySheetEntry .
Thanks in advance !
