Add widget based spellchecker example
This example demonstrates how to convert 'dic' dictionary files
into 'bdict' binary format using qwebengine_convert_dict tool.
It shows how to implement language selection. It adds two dummy
dictionaries.

In this example, we want to support the English and German + languages. + + The Qt WebEngine spellchecker supports dictionaries from the + \l{Hunspell project}, but they have to be compiled into a special binary + format. A Hunspell dictionary consists of two files: + + \list + + \li A \c .dic file that is a dictionary containing words for the + language + \li An \c .aff file that defines the meaning of special flags in the + dictionary + \endlist + + These two files can be converted into the \c bdic format by using the + \c qwebengine_convert_dict tool that is shipped together with Qt. + + In this example, we are going to compile en_US and de_DE dictionaries. + However, the real full dictionaries would take too much space for the + purposes of this example. Therefore, we have created two dummy dictionaries + that contain the following words and can be used to demonstrate the + conversion process: + + \list + \li English dictionary: I, you, he, she, it, we, they, love, loves, qt + \li German dictionary: ich, du, er, sie, es, wir, ihr, sie, Sie, liebe, + liebst, liebt, lieben, liebt, qt + \endlist + + Each word in a dictionary can be prefixed with \c q. For more information + about how to create \c dic and \c aff files, see the Hunspell dictionary + file format specification in the \l{Hunspell Project}. + + When a specific spellchecking language is requested, Qt WebEngine will try + to load the already compiled matching \c .bdic file first from + \e qtwebengine_dictionaries directories relative to the executable, + then it will look in \c QT_INSTALL_PREFIX/qtwebengines_dictionaries. + + We specify the QMAKE_EXTRA_COMPILERS parameter in the project file to add a + conversion step to the build process: + + \quotefromfile webenginewidgets/spellchecker/spellchecker.pro + \skipto CONVERT_TOOL + \printuntil QMAKE_EXTRA_COMPILERS + + To set up a dictionary, we run \c qwebengine_convert_dic passing the + file path of the dictionary \c dic and \c bdic files. The \c aff file and + optional \c delta file are also picked up by the \c convert process. + The output \c bdic file is placed into the \e qtwebengine_dictionaries local + directory, which the application binary will run from. + + \section1 Setting the Spellchecker + + The constructor of our class is trivial. + + \quotefromfile webenginewidgets/spellchecker/webview.cpp + \skipto WebView::WebView + \printuntil } + We define simple mapping between our dictionary filenames and + the actual language display name. We will use that mapping to display names + of dictionaries in the context menu. Spellchecking is disabled by default. + Therefore we also enable spellchecker and set the \e English dictionary. + When Qt WebEngine's spellcheck service initializes, it will try to load the + \c bdict dictionaries and to check them for consistency. + Any errors are logged by using the qWarning() function. + + \section1 Switching the Spellchecking Language + + The current language used for spellchecking is defined per profile, and can + get set using the QWebEngineProfile::setSpellCheckLanguage method. When the + user clicks on an underlined misspelled word, the default context menu + displays up to four suggestions. Selecting one will replace the misspelled + word. We could reimplement a number of suggestions, by overriding + QWebEngineView::contextMenuEvent and using + QWebEngineContextMenuData::spellCheckerSuggestions, but we will demonstrate + how to add langague options in the context menu instead: + + \quotefromfile webenginewidgets/spellchecker/webview.cpp + \skipto void WebView::contextMenuEvent + \printuntil menu->popup + \printline } + + Above, we get the QWebEngineContextMenuData instance using the + QWebEnginePage::contextMenuData method. We use it to be notified when the + user clicks on an editable field and show the \uicontrol {Check Spelling} + item in the context menu. Moreover, if spellchecking is enabled, we also + add the \uicontrol {Select Language} submenu with the supported languages. + When an action is triggered, we set the language with the + QWebEngineProfile::setSpellCheckLanguage call. +*/ diff --git a/examples/webenginewidgets/spellchecker/main.cpp b/examples/webenginewidgets/spellchecker/main.cpp new file mode 100644 index 000000000..0d411f665 --- /dev/null +++ b/examples/webenginewidgets/spellchecker/main.cpp @@ -0,0 +1,54 @@ +/**************************************************************************** +** +** Copyright (C) 2016 The Qt Company Ltd. +** Contact: http://www.qt.io/licensing/ +** +** This file is part of the examples of the Qt Toolkit. +** +** $QT_BEGIN_LICENSE:BSD$ +** You may use this file under the terms of the BSD license as follows: +** +** "Redistribution and use in source and binary forms, with or without +** modification, are permitted provided that the following conditions are +** met: +** * Redistributions of source code must retain the above copyright +** notice, this list of conditions and the following disclaimer. +** * Redistributions in binary form must reproduce the above copyright +** notice, this list of conditions and the following disclaimer in +** the documentation and/or other materials provided with the +** distribution. +** * Neither the name of The Qt Company Ltd nor the names of its +** contributors may be used to endorse or promote products derived +** from this software without specific prior written permission. +** +** +** THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS +** "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT +** LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR +** A PARTICULAR PURPOSE ARE DISCLAIMED.
