From 7c52284b294cb33bc2e5d747e2e3c14d8ab937ae Mon Sep 17 00:00:00 2001 From: Robert Bieber Date: Wed, 21 Jul 2010 07:45:29 +0000 Subject: Theme Editor: Implemented download and decompression of font pack in the preferences dialog. Dialog will also allow the user to set a directory for a custom target database, but the update button doesn't work yet. Also fixed the file filters for open file/open project actions and resized the preferences dialog git-svn-id: svn://svn.rockbox.org/rockbox/trunk@27509 a1c6a512-1295-4272-9138-f99709370657 --- utils/themeeditor/gui/fontdownloader.cpp | 158 +++ utils/themeeditor/gui/fontdownloader.h | 59 + utils/themeeditor/gui/fontdownloader.ui | 87 ++ utils/themeeditor/gui/preferencesdialog.cpp | 32 + utils/themeeditor/gui/preferencesdialog.h | 2 + utils/themeeditor/gui/preferencesdialog.ui | 100 +- utils/themeeditor/gui/skindocument.h | 2 +- utils/themeeditor/models/projectmodel.h | 2 +- utils/themeeditor/models/targetdata.cpp | 11 +- utils/themeeditor/models/targetdata.h | 9 +- utils/themeeditor/quazip/LICENSE.GPL | 341 ++++++ utils/themeeditor/quazip/README.ROCKBOX | 6 + utils/themeeditor/quazip/crypt.h | 133 +++ utils/themeeditor/quazip/ioapi.c | 184 +++ utils/themeeditor/quazip/ioapi.h | 75 ++ utils/themeeditor/quazip/quazip.cpp | 285 +++++ utils/themeeditor/quazip/quazip.h | 346 ++++++ utils/themeeditor/quazip/quazipfile.cpp | 377 +++++++ utils/themeeditor/quazip/quazipfile.h | 442 ++++++++ utils/themeeditor/quazip/quazipfileinfo.h | 73 ++ utils/themeeditor/quazip/quazipnewinfo.cpp | 59 + utils/themeeditor/quazip/quazipnewinfo.h | 109 ++ utils/themeeditor/quazip/unzip.c | 1601 +++++++++++++++++++++++++++ utils/themeeditor/quazip/unzip.h | 354 ++++++ utils/themeeditor/quazip/zip.c | 1221 ++++++++++++++++++++ utils/themeeditor/quazip/zip.h | 235 ++++ utils/themeeditor/themeeditor.pro | 36 +- utils/themeeditor/zlib/zconf.h | 326 ++++++ utils/themeeditor/zlib/zlib.h | 1200 ++++++++++++++++++++ 29 files changed, 7841 insertions(+), 24 deletions(-) create mode 100644 utils/themeeditor/gui/fontdownloader.cpp create mode 100644 utils/themeeditor/gui/fontdownloader.h create mode 100644 utils/themeeditor/gui/fontdownloader.ui create mode 100644 utils/themeeditor/quazip/LICENSE.GPL create mode 100644 utils/themeeditor/quazip/README.ROCKBOX create mode 100644 utils/themeeditor/quazip/crypt.h create mode 100644 utils/themeeditor/quazip/ioapi.c create mode 100644 utils/themeeditor/quazip/ioapi.h create mode 100644 utils/themeeditor/quazip/quazip.cpp create mode 100644 utils/themeeditor/quazip/quazip.h create mode 100644 utils/themeeditor/quazip/quazipfile.cpp create mode 100644 utils/themeeditor/quazip/quazipfile.h create mode 100644 utils/themeeditor/quazip/quazipfileinfo.h create mode 100644 utils/themeeditor/quazip/quazipnewinfo.cpp create mode 100644 utils/themeeditor/quazip/quazipnewinfo.h create mode 100644 utils/themeeditor/quazip/unzip.c create mode 100644 utils/themeeditor/quazip/unzip.h create mode 100644 utils/themeeditor/quazip/zip.c create mode 100644 utils/themeeditor/quazip/zip.h create mode 100644 utils/themeeditor/zlib/zconf.h create mode 100644 utils/themeeditor/zlib/zlib.h (limited to 'utils/themeeditor') diff --git a/utils/themeeditor/gui/fontdownloader.cpp b/utils/themeeditor/gui/fontdownloader.cpp new file mode 100644 index 0000000000..7aa4cd8d57 --- /dev/null +++ b/utils/themeeditor/gui/fontdownloader.cpp @@ -0,0 +1,158 @@ +/*************************************************************************** + * __________ __ ___. + * Open \______ \ ____ ____ | | _\_ |__ _______ ___ + * Source | _// _ \_/ ___\| |/ /| __ \ / _ \ \/ / + * Jukebox | | ( <_> ) \___| < | \_\ ( <_> > < < + * Firmware |____|_ /\____/ \___ >__|_ \|___ /\____/__/\_ \ + * \/ \/ \/ \/ \/ + * $Id$ + * + * Copyright (C) 2010 Robert Bieber + * + * This program is free software;

By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Library General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10.

It can be + * used to read table contents of the ZIP archive and retreiving + * information about the files inside it. + * + * You can also use this class to open files inside archive by passing + * pointer to the instance of this class to the constructor of the + * QuaZipFile class. But see QuaZipFile::QuaZipFile(QuaZip*, QObject*) + * for the possible pitfalls. + * + * This class is indended to provide interface to the ZIP subpackage of + * the ZIP/UNZIP package as well as to the UNZIP subpackage. But + * currently it supports only UNZIP. + * + * The use of this class is simple - just create instance using + * constructor, then set ZIP archive file name using setFile() function + * (if you did not passed the name to the constructor), then open() and + * then use different functions to work with it! Well, if you are + * paranoid, you may also wish to call close before destructing the + * instance, to check for errors on close. + * + * You may also use getUnzFile() and getZipFile() functions to get the + * ZIP archive handle and use it with ZIP/UNZIP package API directly. + * + * This class supports localized file names inside ZIP archive, but you + * have to set up proper codec with setCodec() function. By default, + * locale codec will be used, which is probably ok for UNIX systems, but + * will almost certainly fail with ZIP archives created in Windows. This + * is because Windows ZIP programs have strange habit of using DOS + * encoding for file names in ZIP archives. For example, ZIP archive + * with cyrillic names created in Windows will have file names in \c + * IBM866 encoding instead of \c WINDOWS-1251. I think that calling one + * function is not much trouble, but for true platform independency it + * would be nice to have some mechanism for file name encoding auto + * detection using locale information.

Writing is only possible with the existing instance. + * + * \section quazipfile-sequential Sequential or random-access? + * + * At the first thought, QuaZipFile has fixed size, the start and the + * end and should be therefore considered random-access device. But + * there is one major obstacle to making it random-access: ZIP/UNZIP API + * does not support seek() operation and the only way to implement it is + * through reopening the file and re-reading to the required position, + * but this is prohibitely slow. + * + * Therefore, QuaZipFile is considered to be a sequential device. This + * has advantage of availability of the ungetChar() operation (QIODevice + * does not implement it properly for non-sequential devices unless they + * support seek()). Disadvantage is a somewhat strange behaviour of the + * size() and pos() functions. This should be kept in mind while using + * this class. + * + **/ +class QuaZipFile: public QIODevice { + Q_OBJECT + private: + QuaZip *zip; + QString fileName; + QuaZip::CaseSensitivity caseSensitivity; + bool raw; + qint64 writePos; + // these two are for writing raw files + ulong uncompressedSize; + quint32 crc; + bool internal; + int zipError; + // these are not supported nor implemented + QuaZipFile(const QuaZipFile& that); + QuaZipFile& operator=(const QuaZipFile& that); + void resetZipError()const {setZipError(UNZ_OK);} + // const, but sets zipError! + void setZipError(int zipError)const; + protected: + /// Implementation of the QIODevice::readData(). + qint64 readData(char *data, qint64 maxSize); + /// Implementation of the QIODevice::writeData(). + qint64 writeData(const char *data, qint64 maxSize); + public: + /// Constructs a QuaZipFile instance. + /** You should use setZipName() and setFileName() or setZip() before + * trying to call open() on the constructed object. + **/ + QuaZipFile(); + /// Constructs a QuaZipFile instance. + /** \a parent argument specifies this object's parent object. + * + * You should use setZipName() and setFileName() or setZip() before + * trying to call open() on the constructed object. + **/ + QuaZipFile(QObject *parent); + /// Constructs a QuaZipFile instance. + /** \a parent argument specifies this object's parent object and \a + * zipName specifies ZIP archive file name. + * + * You should use setFileName() before trying to call open() on the + * constructed object. + * + * QuaZipFile constructed by this constructor can be used for read + * only access.

If not all input can be processed (because there is not + enough room in the output buffer), next_in and avail_in are updated and + processing will resume at this point for the next call of deflate(). + + - Provide more output starting at next_out and update next_out and avail_out + accordingly.

(In particular + avail_in is zero after the call if enough output space has been provided + before the call.) Flushing may degrade compression for some compression + algorithms and so it should be used only when necessary. + + If flush is set to Z_FULL_FLUSH, all output is flushed as with + Z_SYNC_FLUSH, and the compression state is reset so that decompression can + restart from this point if previous compressed data has been damaged or if + random access is desired. Using Z_FULL_FLUSH too often can seriously degrade + the compression. + + If deflate returns with avail_out == 0, this function must be called again + with the same value of the flush parameter and more output space (updated + avail_out), until the flush is complete (deflate returns with non-zero + avail_out). In the case of a Z_FULL_FLUSH or Z_SYNC_FLUSH, make sure that + avail_out is greater than six to avoid repeated flush markers due to + avail_out == 0 on return. + + If the parameter flush is set to Z_FINISH, pending input is processed, + pending output is flushed and deflate returns with Z_STREAM_END if there + was enough output space; if deflate returns with Z_OK, this function must be + called again with Z_FINISH and more output space (updated avail_out) but no + more input data, until it returns with Z_STREAM_END or an error.

If not all input can be processed (because there is not + enough room in the output buffer), next_in is updated and processing + will resume at this point for the next call of inflate(). + + - Provide more output starting at next_out and update next_out and avail_out + accordingly. inflate() provides as much output as possible, until there + is no more input data or no more space in the output buffer (see below + about the flush parameter). + + Before the call of inflate(), the application should ensure that at least + one of the actions is possible, by providing more input and/or consuming + more output, and updating the next_* and avail_* values accordingly. + The application can consume the uncompressed output when it wants, for + example when the output buffer is full (avail_out == 0), or after each + call of inflate(). If inflate returns Z_OK and with zero avail_out, it + must be called again after making room in the output buffer because there + might be more output pending. + + The flush parameter of inflate() can be Z_NO_FLUSH, Z_SYNC_FLUSH, + Z_FINISH, or Z_BLOCK. Z_SYNC_FLUSH requests that inflate() flush as much + output as possible to the output buffer. Z_BLOCK requests that inflate() stop + if and when it get to the next deflate block boundary. When decoding the zlib + or gzip format, this will cause inflate() to return immediately after the + header and before the first block. When doing a raw inflate, inflate() will + go ahead and process the first block, and will return when it gets to the end + of that block, or when it runs out of data. + + The Z_BLOCK option assists in appending to or combining deflate streams. + Also to assist in this, on return inflate() will set strm->data_type to the + number of unused bits in the last byte taken from strm->next_in, plus 64 + if inflate() is currently decoding the last block in the deflate stream, + plus 128 if inflate() returned immediately after decoding an end-of-block + code or decoding the complete header up to just before the first byte of the + deflate stream. The end-of-block will not be indicated until all of the + uncompressed data from that block has been written to strm->next_out. The + number of unused bits may in general be greater than seven, except when + bit 7 of data_type is set, in which case the number of unused bits will be + less than eight. + + inflate() should normally be called until it returns Z_STREAM_END or an + error. However if all decompression is to be performed in a single step + (a single call of inflate), the parameter flush should be set to + Z_FINISH. In this case all pending input is processed and all pending + output is flushed; avail_out must be large enough to hold all the + uncompressed data. (The size of the uncompressed data may have been saved + by the compressor for this purpose.) The next operation on this stream must + be inflateEnd to deallocate the decompression state. The use of Z_FINISH + is never required, but can be used to inform inflate that a faster approach + may be used for the single inflate() call. + + In this implementation, inflate() always flushes as much output as + possible to the output buffer, and always uses the faster approach on the + first call. So the only effect of the flush parameter in this implementation + is on the return value of inflate(), as noted below, or when it returns early + because Z_BLOCK is used. + + If a preset dictionary is needed after this call (see inflateSetDictionary + below), inflate sets strm->adler to the adler32 checksum of the dictionary + chosen by the compressor and returns Z_NEED_DICT; otherwise it sets + strm->adler to the adler32 checksum of all output produced so far (that is, + total_out bytes) and returns Z_OK, Z_STREAM_END or an error code as described + below. At the end of the stream, inflate() checks that its computed adler32 + checksum is equal to that saved by the compressor and returns Z_STREAM_END + only if the checksum is correct. + + inflate() will decompress and check either zlib-wrapped or gzip-wrapped + deflate data.
