Text positions in ppt

I'm trying to determine the (x,y) coordinates for TextRuns within a slide (so
I can figure out which one is *really* the title!).  Can someone point me to
some sample code?

Thanks very much,
Larry

The code you need is in Slide#getTitle(), see 
ihttp://svn.apache.org/repos/asf/poi/trunk/src/scratchpad/src/org/apache/poi/hslf/model/Slide.java

To test whether a shape is the title use the following code:

         for(Shape sh : slide.getShapes()){
             if(sh instanceof TextShape){
                 TextShape tx = (TextShape)sh;
                 TextRun run = tx.getTextRun();
                 int type = run.getRunType();
                 if (type == TextHeaderAtom.CENTER_TITLE_TYPE || type == TextHeaderAtom.TITLE_TYPE ){
                     //got title
                     String title = run.getText();

                 }

             }
         }

TextBox is a subclass of TextShape which is a base class of all shapes that can hold text.
The correct code should test for TextShape, not for TextBox:

             if (sh[i] instanceof TextShape){
                TextShape box = (TextShape)
                String text = box.getText();
                ...
             }

I'm running into problems with that, however.  Not all the Shapes that
contain text are TextBoxes; in the presentations I've looked at, some are
Pictures, some are AutoShapes.  I need to get the location for every
TextRun.  If I could access the getShapeId() method in TextRun, it would let
me find the shape corresponding to each, but that method is protected.  Any
tips on how to proceed?

Thanks much,
Larry
