It's ok, but checking both for

(RichViewEdit1->GetItemStyle(0) == 0)

and

(RichViewEdit1->GetItemStyle(0) >= 0)

is redundant.

When you paste text from another editor, it is pasted with its font and

paragraph attributes.

If you delete this text, the attributes remain.

The document is empty, but it's different from the initial empty document -

when you start typing, text has different font, paragraph alignment may

differ, etc. What's why the code above returns false.

Ok, here is less strict checking:

bEmpty = (RichViewEdit1->ItemCount == 0) ||

((RichViewEdit1->ItemCount == 1) &&

(RichViewEdit1->GetItemStyle(0) >= 0) &&

(RichViewEdit1->GetItemText(0).Trim() == ""))
