* added focus listener. Doesn't do much yet, but when focus notifications start appearing, we'll be ready for them. The code is in
place to hide selection when we lose focus and paint selection when we get focus. That's probably not quite right, but it's a start.
We will need to be able to determine the distinction between losing focus to another control within our app, and losing focus to
another app.
* added support for disabled and readonly states in the editor. This is accomplished by having flags set by the client, and letting the
rules system deal with those flags. The flags I added are:
TEXT_EDITOR_FLAG_PLAINTEXT 0x01 // only plain text editing is allowed
TEXT_EDITOR_FLAG_SINGLELINE 0x02 // enter key and CR-LF handled specially
TEXT_EDITOR_FLAG_PASSWORD 0x04 // text is not entered into content, only a representative character
TEXT_EDITOR_FLAG_READONLY 0x08 // editing events are disabled. Editor may still accept focus.
TEXT_EDITOR_FLAG_DISALBED 0x10 // all events are disabled (like scrolling). Editor will not accept focus.
* added WillInsertBreak/DidInsertBreak into text rules, so flags could be checked. This gets us readonly, disabled, and single line
behavior.
* cleaned up the code that allocates, registers, and destroys event listeners. Thanks to Kin and Simon for cleaning up the
ownership model on the listeners, it was a big help.
* added support for a max text length. You can now tell the text editor, be no bigger than n characters.
features like set paragraph style, set list type, indent, etc. I'm sure there's holes in my
implementation that these high level features will make obvious.
2. I've factored a lot of utility methods from several modules into nsEditor as public static methods.
This makes them easily accessable to all, and will help Joe and I remove redundant methods.
3. I changed the HTML tags to lower case, and made all string compares case-insensitive. No, this
isn't quite the right thing to do, but we don't have atoms from layout yet. The Right Thing is for us
to reuse those atoms.
1. fix for bug 5796, crash on exit. This was a bad, bad memory smudge on my part, easily fixed by doing the right ref counting in the
right places.
2. some preliminary code for M6 block transformations has leaked into this checkin. It's safer than trying to re-code the fix above into
a fresh tree. Unless you're making calls to do block transformations, you won't see any difference.
* added TextEditorTest.cpp, a unit test module for nsTextEditor. It's use is actually commented out since my checkin is happening so late due
to all-day build bustage, and I don't have a Mac handy to verify. With someone's Mac help tomorrow, I can turn it on.
* some minor bug fixes to property handling
made a special case for typing with BR as the selection (as after an InsertBreak.)
made DEL and BACKSPACE at the beginning and end of a text node
fixes bugs 3742 and 3756 (with permission from choff and gkostello)
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
