RE: [ve-dev] Accessing Selected object in VE
|
Hi Rashmi,
You're right that unfortunately getEditDomain()
isn't on JavaVisualEditorPart - it should be but somehow got removed. In
the meantime however is the selected object you're getting an EditPart
or an IJavaInstance ? Usually if the selection is on the graphical
canvas or JavaBeans tree viewer then it'll be an EditPart, and there is
a static helper method EditPart.getEditDomain(EditPart anEditPart) that
will return the edit domain.
Best regards,
Joe Winchester

RE: [ve-dev]
Accessing Selected object in VE
Hi Srimanth,
Thanks for the input. I was
able to assign a selection listener to the JavaVisualEditor. Its working
fine. I can display the kind of object that is being selected by doing
toString() to the selection object. Casting it to IJavaInstance provides
with further functionalities. But I am unable to get the edit domain for
the JavaVisualEditorPart as the required method ' getEditDomain()' does
not seem to exist.
I want to loop through all the components
from the root model to get to the component which i want it to be selected.
Can you please help me out.
Thank You and Regards
Rashmi H.Ramachandra

Hi Rashmi,
> how do I get the selected component on the visual editor canvas?
If you can get the EditorPart (JavaVisualEditorPart), you can add a listener
to its site's page's selection provider -
getSite().getPage().addSelectionListener(new
ISelectionListener(){
public void selectionChanged(IWorkbenchPart
part, ISelection selection) {
System.out.println("Selection Changed!");
}
});
> How do I get access to the root model
'JavaVisualEditorPart.getEditDomain().getDiagramData()' will give you the
root model. You can cast it to the 'BeanSubclassComposition' class to access
the this type, the components etc.
Or if you are coming from Codegen's model, 'IBeanDeclModel.getCompositionModel().getModelRoot()'
should give you the 'BeanSubclassComposition' also.
> and the IJAvaInstance of the selected object.
When you get the GEF EditPart of the selected object as described above,
just do a 'getModel()' on the EditPart to get the IJavaInstance.
Regards,
Sri.

| [ve-dev] Accessing Selected
object in VE |
|
hi all,
how do I get the selected component on the visual editor canvas?
How do I get access to the root model and the IJAvaInstance of the selected
object.
I have tried to go through source code of 'org.eclipse.ve.internal.java.codegen.editorpart.BeansList'
and 'org.eclipse.ve.internal.java.codegen.editorpart.JavaVisualEditorPart'.
I am not able to find any entry point for accessing selected objects.
My requirement is to build a tree that partially
replicates the JavaBean View to show both visual and non-visual components
present in the java file in the form of a tree.Is there any API provided
for developers to access the components in the visual editor. I have tried
going through the current API and the source code available for tracking
the JavaBean View components, but it has not been fruitful
Can anybody please help.
