public Class UnoSelection

Returns:Optional<com.sun.star.lang.XServiceInfo>

may be Optional.empty(), or some type supporting XServiceInfo So far it seems the first thing we have to do with a selection is to decide what do we have.

One way to do that is accessing its XServiceInfo interface.

Experiments using printServiceInfo with cursor in various positions in the document:

With cursor within the frame, in text: *** xserviceinfo.getImplementationName: "SwXTextRanges" "com.sun.star.text.TextRanges"

With cursor somewhere else in text: *** xserviceinfo.getImplementationName: "SwXTextRanges" "com.sun.star.text.TextRanges"

With cursor in comment (also known as "annotation"): *** XSelectionSupplier is OK *** Object initialSelection is null *** xserviceinfo is null

With frame selected: *** xserviceinfo.getImplementationName: "SwXTextFrame" "com.sun.star.text.BaseFrame" "com.sun.star.text.TextContent" "com.sun.star.document.LinkTarget" "com.sun.star.text.TextFrame" "com.sun.star.text.Text"

With cursor selecting an inserted image: *** XSelectionSupplier is OK *** Object initialSelection is OK *** xserviceinfo is OK *** xserviceinfo.getImplementationName: "SwXTextGraphicObject" "com.sun.star.text.BaseFrame" "com.sun.star.text.TextContent" "com.sun.star.document.LinkTarget" "com.sun.star.text.TextGraphicObject"

Select the object represented by newSelection if it is known and selectable in this XSelectionSupplier object.

Presumably result from XSelectionSupplier.getSelection() is usually OK. It also accepted XTextRange newSelection = doc.getText().getStart();
