2012-04-05Fixed build error in msvs because Fl ref to FULLSCREEN enum was not ↵Fabien Costantini
accessible in Fl_Widget. new inline is_fullscreen() getter has been implemented to avoid a build error with (at least) msvc compilers. Fixed a ton of warnings / problems when bilding on windows 64 bits target with ms toolchain. cleaned up about 200 warnings raised when building win74 targets. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@9325 ea41ed52-d2ee-0310-a9c1-e6b18d33e121

2010-12-15Homogenize use of re-encoding and transcoding (in favor of the latter).Manolo Gouy
Also, makes clear that the code is ready to deal with any encoding, not just fixed-length ones. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@8040 ea41ed52-d2ee-0310-a9c1-e6b18d33e121

git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@8032 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
2010-12-10Fix STR #2348. Files encoded with UTF-8 or CP1252 are accepted. Any ↵Manolo Gouy
non-UTF-8-encoded data is interpreted according to CP1252 and transcoded to UTF-8. By default, a warning message is displayed when the input file was transcoded. This default behavior can be modified by changing a function pointer. A flag has been added to the Fl_Text_Buffer object that informs the caller if the input file was transcoded to UTF-8. The Fl_Text_Buffer.cxx file contains some preliminary code that could be used in the future to input other encodings provided they are fixed-length (e.g., all ISO-8859-* character sets, UTF-16). This code is not compiled at this point. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@8004 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
2010-12-08Fixed Windows text file line endings, as discussed in STR 2348 andAlbrecht Schlosser
fltk.development. Side effect: All Windows text files written are in Windows, aka DOS format (with CR/LF line endings), no matter what format they had when read. This is compatible with FLTK 1.1. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@7979 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
2010-12-07Restoring the non-binary read for MSWindows files. Still, I think this is ↵Matthias Melcher
harmful because now we read in ASCII and write in binary format... git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@7969 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
2010-12-06Ooops, Fl_Text_Buffer::insertfile must read in binary format, or it will ↵Matthias Melcher
screw up line endings! (Actually, this could be debated, but by reading and writing in binary format, the file integrity would remain) git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@7968 ea41ed52-d2ee-0310-a9c1-e6b18d33e121

2010-12-06Fixed crashes when Fl_Text_* detects illegal UTF 8 sequences. Widgets will ↵Matthias Melcher
not do any further processing but just jump over the character. Screen representation depends largely on whatever the underlying OS does with those sequences, but I feel that this is out of the scope of this library.

2010-11-06Working on correct line wrapping in Fl_Text_Display: starting to replace all ↵Matthias Melcher
byte based charracter calculations with utf8 functions. Current version wraps, but scroll bars are wrong. Non-wrapping text display starts to work better. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@7797 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
2010-11-04Starting to rework Fl_Text_Display from scratch to make wrapping work ↵Matthias Melcher
correctly. Fixed a few issues that made wrapping crash. Using ASCII range only with fixed character sizes should still wrap as expected?! git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@7794 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
2010-11-03STR 2158: partially solved. This commit is huge, I admit. I recoded most of ↵Matthias Melcher
Fl_Text_Buffer and large chunks of Fl_Text_Display to make it UTF-8 safe. Rendering of all left-to-right scripts works well on OS X for all tested fonts. International input works AFAIK. Copy and paste of UTF-8 data works. ----> what's not working yet though is line wrapping. Also, text search for internationsl characters is not working yet. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@7792 ea41ed52-d2ee-0310-a9c1-e6b18d33e121

2010-07-10Updated the Fluid IDE support for the current source file structure. Changed ↵Matthias Melcher
the Fl_Tree rendering code around a bit to make the tree more like MSWindows on Windows and more like Apple on Apple machines. I hope you guys like it. I also moved the function to load Fl_Preferences into an Fl_Tree into the Fl_Tree class where it belongs. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@7672 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
2010-04-20added implementations of fl_wcwidth_() and fl_wcwidth() to src/fl_utf.cengelsman
these supercede the old fl_wcwidth() code in src/xutf8/fl_wcwidth.c. also added corresponding declarations to FL/fl_utf.c, and updated src/Fl_Text_Buffer.c to enable the call to fl_wcwidth() git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@7551 ea41ed52-d2ee-0310-a9c1-e6b18d33e121

This is by no means a fix. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@7440 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
2010-04-05Holy Gucamole! NEdit was designed with 'C' style strings in mind. Until that ↵Matthias Melcher
is that someone had the great idea to allow <nul> as a valid character in the text editor. The developers jumped through quite some hoops to allow that without rewriting the core. Well, actually they did: they added a parameter to pretty much every internal call that conatined the null-replacement-character. Anyway, since we only handle 'C' strings, I remove all related code. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@7437 ea41ed52-d2ee-0310-a9c1-e6b18d33e121

2010-04-05I humbly apologize for this commit, but I just could not bear it anymore. I ↵Matthias Melcher
moved all Doxygen comments from Fl_Text_Buffer.cxx into the header (I kept searching back and forth for the comments) and then did the unthinkable: I reformatted Fl_Text_Buffer.cxx! OMG. It is actually somewhat *readable* now. I shouldn't have done it! It's a mess ;-). Fl_Text_Buffer was modified many times to do things it was never designed to do. And looking at 'svn b;ame', I remember that I tried to quick-fix UTF-8 on top of that. Anyway, I'll dig into this now. I want 1.3.0 out of the door (end of ramble). git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@7432 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
2009-07-04Fl_Text_Display C code simple refactoring:Fabien Costantini
+ Replaced uninitialized C parameters archaisms, by on the fly C++ local var. decl.

2008-09-21More doxygen updates for Fl_Text_Buffer. Also changed some argumentAlbrecht Schlosser
names from "char *s" to "char *text" to be in sync with the docs. Caution: If there will be name conflicts with Fl_Text_buffer::text(), then this can at least be fixed easier, because searching for "text" is better than for "s". I remember that some argument names x,y,w,h have been changed to uppercase, because of conflicts with x(), etc. with ... valgrind (?) or maybe some compilers ? I did this deliberately, because changing the headers and doxygen docs to "s" instead of "text" appeared to be not feasible. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@6326 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
