Textinput MUI Custom Class ========================== This is a combined single/multi line editor gadget. Key features: · only one compact class for single line/multi line mode, efficient due to code sharing · same prefs for single line/multi line mode · optional external editing in sync/async mode for multi line mode · fully configurable key bindings · supports cut & paste · supports many style configuration options including blinking and bar cursor · includes numeric mode with upper/lower bounds check · support old stringclass tags/methods for easy "drop in" replacement in existing code · works nicely in virtgroups (unlike the gadgetclass based stringclass) The class is still somewhat in "beta" and doesn't yet have proper documentation. Include file and demo program source are included, though. History ------- 11.10 ----- (first public release included in MD-2 0.182beta) 11.11 ----- - paste from clipboard now works - fixed all kind of problems with internal status loss during certain operations - SHIFT-DEL and SHIFT_BS now delete to beginning/to end of line 11.12 ----- - fixed problems with marking/cursor pointer pointing to freed mem on a buffer expand - major speedup in text output - cut & copy into clipboard now works 11.13 ----- - setting MUIA_(Textinput|String)_Contents with NULL caused enforcer orgy 11.14 ----- - prefs now have a "Samples" page of their own to make the group fit on 640x200 screen - gadget didn't go inactive upon a cleanup - DoCopy will now copy the whole contents to clipboard if no block is marked 12.0 ---- - totally changed key control settings; keys are now a list of key/action pairs (up to 32). It's now possible to specify more than one key for an action. - added a key action for calling external editor (defaults to "ramiga e") - added MUIA_Textinput_MinVersion attribute; object refuses to create itself if the required version is less than current version 12.1 ---- - fixed another problem with buffer expanding - fixed another problem with active state loss 12.2 ---- - added asynchronous external editor mode. If set, editor is called asynchronously, object remains enabled and a notification is made on the temp file. If changes to the file are made, it is reread. - added default popup menu (defaults to on for multi, off for single line objects) - speed up pasting of text from clipboard - text input is generally faster now - no longer craps out when trying to past multi line strings into a single line gadget 12.3 ---- - "Mark all" would place the cursor pointer past the end of the buffer, thus creating all kind of not so neat side effects - copying all text to clipboard caused to add a 0 byte at the end of the data - Added optional wordwrap. 12.4 ---- - pressing lamiga/ramiga command keys no longer activates any window menu shortcuts 12.5 ---- - shortended popup menu title size - wordwrap now defaults to "ON" for multi line gadgets (70 chars) - "Cut line" now works as advertized - fixed problem with cutting text loosing cursor pointer focus 12.6 ---- - wordwrap defaults can now be specified in the prefs - external editor can now be started multiple times in async mode 12.7 ---- - fixed resetting of drawmode to JAM1 (fixes artefacts) - setting/getting of MUIA_Textinput_Integer (and _String_Integer/_Numeric_Value) now works - added MUIA_Textinput_Changed attribute 12.8 ---- - fixed problems with D&D (Mousebutton events weren't eaten up, thus triggering D&D during mark) - now handles attached popup and attached lists correctly - pressing return in a single line gadget while text is marked no longer replaces that text 12.9 ---- - fixed a problem with blinking cursor trashing the rastport drawmode 13.0 ---- - now all keys are configurable independant of MUI navigation prefs - added MUIA_Textinput_RemainActive attribute. Object will remain active even after pressing RETURN in a single line gadget. - added MUIM_Textinput_Acknowledge method which is sent on pressing RETURN. Default handling is set() of MUIA_Textinput_Acknowledge and MUIA_String_Acknowledge to rootclass for backward compatibility. - AcceptChars/RejectChars now work - IsNumeric now works, including range checking - notification on MUIA_Textinput_Changed is now possible - added MUIM_Textinput_TranslateEvent hook method which allows to hook into textinput's inputevent->string translation. MapRawKey() has already been called at this place so the subclass can directly modify the translated buffer. - MUIM_HandleEvent is now called on the real class, instead of being coerced on the textinput class directly, to allow to totally hook the input handling - added MUIM_Textinput_InsertText method to insert text at the current cursor position - pasting of multi line text into single line gadget is now possible; the application must be careful to process all text during the MUIM_Textinput_Acknowledge method (or notification triggered on MUIA_Textinput_Acknowledge), because the method is called for every line in the clipboard data - added support for MUIA_Textinput_Secret/MUIA_String_Secret. Will not allow cutting/copying from such strings to avoid easy revelation of the password in question - setting MUIA_Textinput_Contents now causes the cursor to be at the end of the text, not at the beginning - multi line textinputs with scroller no longer send a scroller inform when the scroller positions haven't changed. Speeds up general option esspecially during text input. - added word left/right functionality 13.1 ---- - moved DEL/BS and TAB functionality to configurable keys, too - changed key config ID to avoid clashes with previous (incomplete) key bindings - fixed duplicate IDs for wordwrap on and wordwrap column - HELP key no longer causes CSI trash to be inserted into strings 13.2 ---- - various operations which modified contents didn't actually trigger notification on MUIA_Textinput_Contents/Changed. - RemainActive now disables the automatic deactivation of the gadget when clicking outside of the container bounds - fixed the "Last line" bug - fixed bogus xoffset not resetting to 0 on set() of string contents 13.3 ---- - fixed popup menu "Word wrap" toggling - fixed string insertion to not always trigger a string acknowledge when inserting strings without \n - fixed excess scrollbar refreshes 13.4 ---- - added MUIA_Textinput_Lines attribute (notificable) - fixed problems with cursor not being made properly visible when a left scroll is required - fixed TAB to not do a double jump - now holds a class global cache of translated input expressions; reduces object setup time drastically and reduces per-object memory requirements - fixed a few more potential problems with the scroll bars not being updated correctly - textinputscroll.mcc now properly forwards MUIM_Notify to the textinput object only 13.5 ---- - no longer disables menu shortcuts when active 13.6 ---- - added MUIA_Textinput_Editable - works around a nasty problem with IEQUALIFIER_MIDBUTTON being set on every and all input events on some systems, thus making the input handling not match anything. Now strips down matched Qualifiers to keyboard only (without CAPSLOCK) 13.7 ---- - unmapped special keys no longer cause bogus CSI sequences to be inserted - now handles menu shortcuts again (textinput key defs take precedence, though) - external edit button is now properly disabled in noedit mode - "external edit" popup entry is now properly disabled in noedit mode - secret mode no longer shows a bogus char at the end of line - "cut line" no longer copies to clipboard (and therefore now works in secret mode, too) - "cut line" didn't check whether the cursor was still visible - revert changes now works - pasting of multi line text into single line gadgets was hosed 13.8 ---- - now raises task priority for more smooth input handling when active - changed default key binding for "cut line" to "ramiga y" and for "cut marked" to "ramiga x" - "Cut marked" now behaves differently in single line mode; if nothing is marked, the gadget is erased completely (to match standard amiga string gadget behavior) - added double click mark handling; double click selects word, triple click line, quad click everything and more clicks deselects again - added "backspace to start of word" and "delete till end of word" functionality, default mappings to control-bs/del - menu shortcuts no longer trigger gadget shortcuts 13.9 ---- - no longer inserts a bogus blank when tabbing out of the gadget - added MUIM_Textinput_InsertFromFile functionality - added "Insert file" UI functionality; default key binding "ramiga shift o" 13.10 ----- - added MUIA_Textinputscroll_UseWinBorder - priority will now be set to normal if the window containing the gadget is deactivated 13.11 ----- - now using highly optimized TextFit/TextLength replacement for better output speed 13.12 ----- - improved overall speed with various internal optimizations - fixed cursor size to be calculated from the font's blank width, not tf_XSize, which could cause problems with some font sets 13.13 ----- - Prefs: Label for cursor colors accidentally read "marked", too - fixed a problem with characters not part of the current font messing up the size calculations - now compiled with SAS/C 6.58 13.14 ----- - notify events are now directly CoerceMethod()ed on the notify class to avoid going through the areaclass dispatcher/OM_SET method 13.15 ----- - now sets writemask/maxpen on planar display for much better rendering speed on AGA systems 13.16 ----- - fixed a problem with the font not being set on initial redraws - fixed a problem with planemasks not being reset when rendering the cursor, thus causing all kinds of artifacts 13.17 ----- - fixed a problem with the gadget not setting up properly when text was set()ed before receiving a MUIM_Setup 13.18 ----- -

reenabled double click functionality 13.19 ----- - modified default color scheme to use the BOOPSI stringclass alike color inversions for rendering the cursor - fixed problems with the gadget remaining visually "active" even when the window containing the gadget was deactivated - fixed task priority screwing 13.20 ----- - fixed disabling of Wordwrap/Insert file popup menu items for "NoEdit" mode gadgets - fixed screwup with non-proportional fonts 13.21 ----- - default cursor color is now the complement of the active string color, not the standard string color (this matches stringclass behavior) 13.22 ----- - now recognizes some language specific chars as parts of words when jumping - fixed a longstanding bug in the font width calculation which went berzerk upon hitting a non-printable character (control codes, for example) 13.23 ----- - fixed a bug with textinput going mad if the char kerning table had a negative value (xhelvetica, for example) - "cut" didn't update some internal cursor state variables thus causing some messup 13.24 ----- - fixed another bug related to characters below tf_LoChar being in the font set - fixed a race condition with MUIM_GoActive ariving before MUIM_Show/MUIM_Setup - fixed a problem with wordwrap not stopping on a line which had other whitespaces before the trailing \n -

fixed a long standing bug with asynchronous external editor calls only working once - added MUIA_Textinput_MarkStart | _MarkEnd attributes which return the byte offset of the marked area start/end or MUIV_Textinput_NoMark 13.26 ----- - fixed another problem with the activation state being lost under certain circumstances 13.27 ----- - fixed serious bug with DoubleClick moving the internal mark start pointer before the actual buffer, causing all kinds of neat side effects including Major Crash® - fixed cursor refresh problem when cursor was on a char with negative kerning values 13.28/29 (internal only) ------------------------ 13.30 ----- - added hyper textfit/textlen code from V/MUI 4.0, improving output speed and esspecially input response times 13.31 ----- -

modified the activate/inactivate handling a bit 13.34 ----- - fixed handling of menu shortcut selection while TI is active - fixed window activation sometimes not causing a proper redraw of the currently active TI object - fixed some longword boundary alignments in TI's data structure which could cause uneccessary slowdowns on 68020+ - fixed button up events to no longer trigger a whining "Hey, this is a readonly-gadget!" beep in readonly mode - did some general optimizations speeding up normal input 13.35 ----- - now strips \r when OM_SETting the complete buffer - fixed another instance of the bogus "Hey, I'm readonly" DisplayBeep()-whining - fixed broken cursor offset calculation in secret mode - optimized calculation of current line length 13.36 ----- - fixed a serious bug in the drawline code which could cause a RectFill() call with min/max exchanged, thus causing a nuke on AGA - removed all calls to OldOpenLibrary() to make Richard Körber happy 13.37 ----- - fixed a serious internal state screwup which occured when ramiga b ("mark start") was pressed and no cursor movement followed up before an actual key was entered -- basically ended up in a strcpy( -1, -1 ); 13.38 ----- - fixed a potential race condition when creating menu events from hotkeys which caused a MUIM_Cleanup operation (most notably direct notifications to MUIA_Application_Iconified) 13.39 ----- - added support for Contact Manager direct insertion 13.40 ----- - textinput.mcp didn't save wordwrap settings 13.41 ----- - fixed MUIA_ControlChar handling (thanks Zapek) 13.42 ----- - fixed the task priority screwing which only caused trouble anyway.
