/* * RICHED20 TODO (incomplete): * * - messages/styles/notifications listed above * - 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) * - 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? * */
