and merges in subsequent transactions indiscriminately until it's told to stop.
It also gives the last transaction in its child list a chance to merge the
next transaction.
All this is in support of complex transactions that result in text insertion
being able to collapse into a single undoable event.
Also improved tracking of bogus content node used when document is empty.
trivial to add more properties
finished first cut at SetTextProperty. This triggers lots of crashes in
range/selection code where we're holding onto a stale frame pointer (at
least, that's my best guess.)
synched with Charlie's change-o-rama
added an assert in DeleteTextTxn::Init() checking aNumCharsToDelete vs.
0
NS_ASSERTION(0!=aNumCharsToDelete, "bad arg, numCharsToDelete");
if the number of chars to delete is 0, we shouldn't be creating a
transaction at all. I had never seen this condition arise before
Charlie's checkin, I don't know if he introduced it or if it was a
latent bug I just never tripped over before.
updated to new nsCOMPtr usage
nsTextEditor::InsertBreak() implemented
splits the text node at the caret (deletes any extended selection to force a collapsed selection.)
inserts a <BR> which I assume we'll convert to a CR when we write to a text stream.
undo and redo work, except for the bug noted below
More stuff:
interface cleanup
strategic debugging code added
delete selection txn sets the collapses the selection...this is just a placeholder, but I needed it for undo/redo of InsertBreak.
join and split now work for text nodes as well as interior nodes
* added DeleteSelection to editor. Doesn't work very well yet because selection is giving me random offsets into text content.
* lots of work in the various transactions.
