/*
|
|
* RICHED20 TODO (incomplete):
|
|
*
|
|
* - messages/styles/notifications listed above
|
|
* - Undo coalescing
|
|
* - add remaining CHARFORMAT/PARAFORMAT fields
|
|
* - right/center align should strip spaces from the beginning
|
|
* - pictures/OLE objects (not just smiling faces that lack API support ;-) )
|
|
* - COM interface (looks like a major pain in the TODO list)
|
|
* - calculate heights of pictures (half-done)
|
|
* - horizontal scrolling (not even started)
|
|
* - hysteresis during wrapping (related to scrollbars appearing/disappearing)
|
|
* - find/replace
|
|
* - how to implement EM_FORMATRANGE and EM_DISPLAYBAND ? (Mission Impossible)
|
|
* - italic caret with italic fonts
|
|
* - IME
|
|
* - most notifications aren't sent at all (the most important ones are)
|
|
* - when should EN_SELCHANGE be sent after text change ? (before/after EN_UPDATE?)
|
|
* - WM_SETTEXT may use wrong style (but I'm 80% sure it's OK)
|
|
* - EM_GETCHARFORMAT with SCF_SELECTION may not behave 100% like in original (but very close)
|
|
* - full justification
|
|
* - hyphenation
|
|
* - tables
|
|
* - ListBox & ComboBox not implemented
|
|
*
|
|
* Bugs that are probably fixed, but not so easy to verify:
|
|
* - EN_UPDATE/EN_CHANGE are handled very incorrectly (should be OK now)
|
|
* - undo for ME_JoinParagraphs doesn't store paragraph format ? (it does)
|
|
* - check/fix artificial EOL logic (bCursorAtEnd, hardly logical)
|
|
* - caret shouldn't be displayed when selection isn't empty
|
|
* - check refcounting in style management functions (looks perfect now, but no bugs is suspicious)
|
|
* - undo for setting default format (done, might be buggy)
|
|
* - styles might be not released properly (looks like they work like charm, but who knows?
