get the currently selected shaoe from impress

Yes, get the current XController from the XModel and use the

XSelectionSupplier interface on it. This either returns a
single
XShape reference or a sequence of XShape for multi
selections.

Thanks for your reply, i had created the code as u
told...but it is showing
null pointer exception..the code is

public void callPlayer(XScriptContext xSc) {
        String name="";
        XComponent xComponent = xSc.getDocument();

        XModel xModel = (XModel)
UnoRuntime.queryInterface(XModel.class,
xComponent);
        XController xController =
xModel.getCurrentController();
        XSelectionSupplier xSelection = (XSelectionSupplier)
UnoRuntime.queryInterface(XSelectionSupplier.class,xControll
er);
        Object temp =  xSelection.getSelection();
        XShape getShape = (XShape)
UnoRuntime.queryInterface(XShape.class,temp);

        XPropertySet xShpProp = (XPropertySet)
                               
UnoRuntime.queryInterface(XPropertySet.class,
getShape);
        try {
           name =
xShpProp.getPropertyValue("Name").toString();
        } catch (UnknownPropertyException ex) {
            ex.printStackTrace();
        } catch (WrappedTargetException ex) {
            ex.printStackTrace();
        }

the method getSelection returns a ShapesCollection.
Therefore you  
could query this to css.container.XIndexAccess and then make
use of  
the method getByIndex() to get your shape.

Hope that helps

yes, I queryed with xshapes and used getbyindex method its
working
fine...now the problem is on click of the shape iam calling
macro which
should find which shape is clicked..for this getting the
selected shape is
not working correctly...so is there any other(interfaces)
way to find which
shape is clicked?

what do you mean with "not working correctly" ?
If only one shape is selected the "getSelection()"
method will be a  
collection of shapes that consists of only one shape.
If you mean by "clicking on it" that you have a
cursor inside the  
shape afterwards, than the selection is indeed the ShapeText
... is  
that what you meant by not working ?

Hi Stephan,
getSelection is working correctly...that is not the
problem..i am clearly
descriping the scenario here
i had inserted a shape inside impress document and made
interaction(Onclick)
of the shape to call a macro. this macro contains the code
to get the
currently selected shape.

So if i click the shape the macro is called before the shape
got
selected...so the macro code cannot find the selected
shape...what iam
asking now is is there any other way get the shape which is
clicked.

now that is a bit inconvenient 
What I'd do is add a SelectionChangeListener ... when your
"Shape" is  
clicked and an "selectionChanged" event should be
fired and you can  
work with that.
In Basic something like the following should work when
binding the  
"OnClick" event to the method "OnClick"

global xListener

Sub OnClick
xListener = createUNOListener 
("cb_","com.sun.star.view.XSelectionChangeLis
tener")
xView = ThisComponent.currentController
xView.addSelectionChangeListener(xListener)
End Sub

sub cb_selectionChanged()
xView = ThisComponent.currentController
xSelection = xView.getSelection

REM "remove Listener"
xView.removeSelectionChangeListener(xListener)

if not isEmpty(xSelection) then
	msgbox xSelection.dbg_supportedInterfaces
endif
end sub

Hope that helps

Hi Stephan,
whether the getselection works when the shape is clicked
during slide
show..i.e) when the shape is linked to macro and working
fine in normal
impress document..when the slideshow is started is that
possible to get
current  documents and shape selected.

in presentation view nothing is selected and so the
selection changed  
event will most likely not be fired.
I suppose the easiest way to handle this would be to create
one  
method for each shape where the shape's name is handed over
to a  
method that does what has to be done with all shapes.

Somethings like

sub shape1_click
	doShapeStuff("Shape1")
end sub

sub doShapeStuff(ShapeName as String)
	xShape=ThisComponent.DrawPages(0).getByName(ShapeName)
	'...
	' do something brilliant 
	'...
end sub

Hope that helps
