qtvirtualkeyboard Chinese word candidate list on embedded linux
-
Hello,
I have been ported QT 5.11.3 to my own embedded linux platform, based on ARM v7a chip.
This is running on windowns7 created by QTCreator 4.9.2 , with QT 5.11.3.
I can select the word what i need from upside candidate list.
But when I compile and run it on my embedded system, select bar won't appear after i typed the spell.
this is my code:

I tryed to use
QtQuick.VirtualKeyboard.Settings 2.2set variable.
wordCandidateList.alwaysVisible = trueit shows candidate list rectangle now, but still empty, no any candidate appear.

I found that Japaneese Kanji work normally, maybe it's chinese dictionary problem.

Hello guys.
I solved the problem.It's because of dictionary path compiled as absolute prefix path.
I checked the source code,
qtvirtualkeyboard\src\virtualkeyboard\tcinputmethod.cpp382 if (inputMode == InputEngine::Zhuyin) { 383 if (d->zhuyinDictionary.isEmpty()) { 384 QString zhuyinDictionary(qEnvironmentVariable("QT_VIRTUALKEYBOARD_ZHUYIN_DICTIONARY")); 385 if (zhuyinDictionary.isEmpty()) 386 zhuyinDictionary = QLibraryInfo::location(QLibraryInfo::DataPath) + "/qtvirtualkeyboard/tcime/dict_zhuyin.dat"; 387 d->zhuyinDictionary.load(zhuyinDictionary); 388 } 389 d->wordDictionary = &d->zhuyinDictionary; 390 }Line 386 :
It used QLibraryInfo, the datapath equals prefix path .I am not expert in QT, but in this case it is not related by qt path on my platform,
I thought the path should be "$QT_ROOT/prefix".
But actually , it used "/prefix" as absolute path.
So I have to move the dictionary file to"/prefix/qtvirtualkeyboard/tcime/dict_zhuyin.dat"
instead of"&QT_ROOT/prefix/qtvirtualkeyboard/tcime/dict_zhuyin.dat"that's why Japanese work fine, because it implemented without external dictionary.
Is this a bug ? Or just my misunderstanding of QT.

Hi and welcome to devnet,
What is the code for the working dictionary ?

I changedenum QLibraryInfo::LibraryLocationtype.
fromQLibraryInfo::DataPathtoQLibraryInfo::PluginsPath,
also moved qtvirtualkeyboard folder from/toQT_PLUGIN_PATH/.382 if (inputMode == InputEngine::Zhuyin) { 383 if (d->zhuyinDictionary.isEmpty()) { 384 QString zhuyinDictionary(qEnvironmentVariable("QT_VIRTUALKEYBOARD_ZHUYIN_DICTIONARY")); 385 if (zhuyinDictionary.isEmpty()) 386 zhuyinDictionary = QLibraryInfo::location(QLibraryInfo::PluginsPath) + "/qtvirtualkeyboard/tcime/dict_zhuyin.dat"; 387 d->zhuyinDictionary.load(zhuyinDictionary); 388 } 389 d->wordDictionary = &d->zhuyinDictionary; 390 }I checked this:
Qt Virtual Keyboard Deployment GuideIt said:
For example, for Qt libraries built from source, it could be qtbase/qtvirtualkeyboard/tcime/dict_zhuyin.dat.It was,but for embeded system, we won't provide QTBASE envirement variable, made this is not really portable ,
but we'll setQT_PLUGIN_PATH, that's why I made the change;
And this,
enum QLibraryInfo::LibraryLocation
says,QLibraryInfo::DataPath :The location of general `architecture-independent` Qt data.Truely cause me misunderstanding. I don't know this is meaning
absoluteorportable.
