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.
attribute MOZ_EDITOR_BOGUS_NODE set to TRUE. this solves the problem of when you do a SelectAll then a DEL, you don't have a cursor
or any way to set selection in the document. You do still have the problem that the nbsp is pretty narrow and the frame containing it is hard to hit
with the mouse. We really need the "set selection to frame nearest the mouse down point" operation.
the intent is for all inserts to look for this node, and if found delete it before the insert. likewise, all deletes will be no-ops if this node is found.
Added nsEditor::DoInitialInsert() for doing first insert into an empty document. Try typing into <html><body></body></html>
Added some smarts to DeleteSelectionAndCreateNode() so it only splits the selected node when appropriate (when the selection is not at offset 0 or max)
CreateElementTxn now creates text nodes as well as DOM elements
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.
added nsEditProperty
beginning of implementation for SetTextProperties. Currently, it only works if the selection is entirely within a single text node. Currently only
supports bold and italic (mapped to ctrl-b and ctrl-i for testing purposes.)
changed a bunch of interfaces to make things easier, like CreateElement now returns (as an out-param) the element created.
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
* the TxnMgr is invoked by the editor via nsRepository
* editor.h|cpp have been renamed nsEditor.h|cpp for consistency
* editorInterfaces.h|cpp have been renamed nsEditorEventListeners.c|hpp
* added nsITextEditor.h, nsTextEditor.h|cpp. The text editor is a placeholder for the rules unique to text
editing. It invokes the nsIEditor to do core editing operations.
* reworked nsIEditor and related interfaces as per emerging design.
* nsEditor::BeginTransaction and EndTransaction call nsTransactionManager::BeginBatch and EndBatch.
