* Update copyright headersJani Heikkinen2015-02-111-1/+1
| | | | | | | | | | | | | | | | | | Qt copyrights are now in The Qt Company, so we could update the source code headers accordingly. In the same go we should also fix the links to point to qt.io. Outdated header.LGPL removed (use header.LGPL21 instead) Old header.LGPL3 renamed to header.LGPL3-COMM to match actual licensing combination. New header.LGPL-COMM taken in the use file which were using old header.LGPL3 (src/plugins/platforms/android/extract.cpp) Added new header.LGPL3 containing Commercial + LGPLv3 + GPLv2 license combination Change-Id: I6f49b819a8a20cc4f88b794a8f6726d975e8ffbe Reviewed-by: Matti Paaso <matti.paaso@theqtcompany.com>

* QCharAttributes: add wordStart/wordEnd flagsKonstantin Ritt2012-09-261-1/+9
| | | | | | | | | | | | | | | A simple heuristic is used to detect the word beginning and ending by looking at the word break property value of surrounding characters. This behaves better than the white-spaces based implementation used before and makes it possible to tailor the default algorithm for complex scripts. BIG FAT WARNING: The QCharAttributes buffer now has to have a length of string length + 1 for the flags at end of text.

* A step out from Harfbuzz (reduce dependency)Konstantin Ritt2012-09-221-10/+10
| | | | | | | | | | | | | | | | | Introduce QCharAttributes and use it instead of HB_CharAttributes everywhere in Qt (in Harfbuzz, the HB_CharAttributes is only used in the text segmentation algorithm which has been moved from HB to Qt (well, most of it)). Rename some members to better reflect their meaning, remember to keep HB_CharAttributes in sync with QCharAttributes. Also replace HB_ScriptItem with a (temporary) QUnicodeTools::ScriptItem struct that will be replaced with a more efficient/friendly solution a bit later. The soft hyphen and the mandatory break detection has been factored out of the default text breaking algorithm to a higher level in order to refactor the QCharAttributes bitfields and to optimize the implementation for the common case.

* Shift positions for lineBreakTypeKonstantin Ritt2012-06-071-2/+1
| | | | | | | | | | | | | | | | | | | to keep them consistent with positions for all other flags. This changes the internal behavior so that attributes[0].lineBreakType now means "break opportunity at start of the text (before the first character in the string)" and is always assigned with HB_NoBreak to conform rule LB2 (see http://www.unicode.org/reports/tr14/#LB2). The current implementation is based on the sample implementation from tr14 that aimed to be as simple as possible rather than to be optimal. From now, we can use pieces of the attributes array "as is" without having to adjust some positions. Or we can analize some long text by chunks (e.g. paragraph by paragraph) and consume less memory. This introduces a minor overhead that will be eliminated shortly. Change-Id: Ic873a05a9d5203b1c3d5aff2e4445a3f034c4bd2 Reviewed-by: Lars Knoll <lars.knoll@nokia.com>

* Harfbuzz-thai: Hide ZWJ and ZWNJ characters and show Inherited charactersJohn Tapsell2012-02-231-3/+8
| | | | | | | | | | | | | | | | | | | | | | | Thai is not supposed to have ZWJ and ZWNJ characters or any other of the Inherited Unicode Scripts (http://www.verisigninc.com/assets/idn-inherited-unicode-script.pdf) - they don't have a mapping to the thai encoding tis620 which libthai requires. However it is an unfortunate fact that there are many websites etc that liberally place these ZWJ and ZWNJ characters throughout thai text to force word boundaries, so we must also deal with them. We deal with all Inherited characters by mapping them to the invalid code ~0 in tis620 encoding, following what libthai does internally in its own tis620 encoding functions, and then replacing this character with the original unicode and setting dontPrint to true to hide the ZWJ and ZWNJ characters. Includes a unit test to check the behaviour.
