Hi!
I created submenu in standard popup menu.
Here the code generated:

public class ActionExportDB implements IObjectActionDelegate {

private Shell shell;

/**
* Constructor for Action1.
*/
public ActionExportDB() {
super();
}

/**
* @see IObjectActionDelegate#setActivePart(IAction, IWorkbenchPart)
*/
public void setActivePart(IAction action, IWorkbenchPart targetPart) {
shell = targetPart.getSite().getShell();
}

/**
* @see IActionDelegate#run(IAction)
*/
public void run(IAction action) {


/// DO SOME ON CLICK

}

/**
* @see IActionDelegate#selectionChanged(IAction, ISelection)
*/
public void selectionChanged(IAction action, ISelection selection) {
}

}


How I get View object from this parameters or how i get nodes in diagramm?
Thanks!

Hello Andrei,

You run action on EditPart, therefore the editpart should be calculated using
selection parameter:

public void selectionChanged(IAction action, ISelection selection) {
if (selection instanceof IStructuredSelection) {
IStructuredSelection structuredSelection = (IStructuredSelection)
selection;
if (structuredSelection.getFirstElement() instanceof GraphicalEditPart)
{
mySelectedElement = (GraphicalEditPart) structuredSelection.getFirstElement();
}
}
}

mySelection is selected EditPart. View can be got from EditPart using GraphicalEditPart#getNotationView()
method.


Best wishes,
Tanya.

Hi, Tatiana!
Thanks for your post.

I get Elements with
MainScheme modelElement = (MainScheme) view.getElement();
for (Iterator it = modelElement.getRefToWinGraphObject().iterator(); it
.hasNext();) {
WinGraphObject childElement = (WinGraphObject) it.next();

}

where WinGraphObject is a node(standard rectangle) of diagramm;

But, how i can get XY layout of this node?

Do i need get Figure from Element?

Thanks!
Andrei.

Hi Andrei,

You need coordinates of the figure, am I correct?
To get coordinates you can
- Work with Nodes.
View can be either Node, or Edge or Diagram. For Node call getLayoutConstraint()
method. If LayoutConstraint is instance of org.eclipse.gmf.runtime.notation.Bounds,
you can easily get location and size.

or
- Work with with EditParts.
To get IFigure call GraphicalEditPart#getFigure() method, then call IFigure#getBounds().


Best wishes,
Tanya.

Thank for your reponse.

my solution is :

Diagram myDiagram = view.getDiagram();
List<Node> nodeList = myDiagram.getChildren();

for (Node node : nodeList){
if (node.getLayoutConstraint() instanceof Bounds){
Bounds bounds = (Bounds)node.getLayoutConstraint();
Integer x = bounds.getX();
Integer y = bounds.getY();
}
}
