Hi Yegor,

I have two queries regarding groups:

1. While it is possible to create new shapes in a group, I couldn't
find a way to add existing shapes to an XSLFGroupShape object. Is this
possible?

2. Is there a way to Ungroup shapes in a PPTx file?

Thanks,
Ankit

You can't add existing shapes to XSLFGroupShape, but you can create a
new shape and copy contents of an existing shape into it :

        XSLFAutoShape existingShape = ...;
        group.createAutoShape().copy(existingShape);

        XSLFTextBox existingTextBox = ...;
        group.createTextBox().copy(existingTextBox)

No, it is not supported. Ungroupping is not that simple: the code will
need to iterate over group, convert each shape's XML into non-group
form. Then it needs to transform anchors to the parent coordinate
system (slide or parent group if it is a nested group) and finally
delete the shape from the group and re-attach it to the parent.
