\title Building Qt Virtual Keyboard
\section1 Overview
This document describes how to build the Qt Virtual Keyboard plugin.
The project is split into the following subprojects:
\table
\row
\li \e examples/virtualkeyboard/basic/basic.pro
\li Qt Virtual Keyboard Demo application
\row
\li \e src/virtualkeyboard/import/
\li Qt Virtual Keyboard QML plugin (QtQuick.VirtualKeyboard)
\row
\li \e src/virtualkeyboard/plugin/
\li Qt Virtual Keyboard platform input context plugin. This plugin
provides the QPlatformInputContext interface for the Qt and is
also responsible for loading the Virtual Keyboard Plugins
(QtQuick.VirtualKeyboard.Plugins).
\row
\li \e src/virtualkeyboard/plugins/
\li A directory containing Qt Virtual Keyboard plugins, such as the Hunspell plugin
\row
\li \e src/virtualkeyboard/settings/
\li Qt Virtual Keyboard Settings QML plugin (QtQuick.VirtualKeyboard.Settings)
\row
\li \e src/virtualkeyboard/styles/styles.pro
\li Qt Virtual Keyboard Styles QML plugin (QtQuick.VirtualKeyboard.Styles)
\row
\li \e src/virtualkeyboard/virtualkeyboard.pro
\li Qt Virtual Keyboard module, QML components and layouts
\endtable
The input methods are implemented either in C++ or QML.
Qt Virtual Keyboard provides implementations of \e PlainInputMethod,
\e MultitapInputMethod and \e HunspellInputMethod.
The \e MultitapInputMethod is implemented in QML while the others are implemented
in C++.
\section1 Build Instructions
The Qt Virtual Keyboard can be built for Linux Desktop/X11, Windows Desktop
or Boot2Qt targets.
The target is automatically detected by QMAKE and requires no special
configuration parameters.
Qt Creator is the preferred build environment for Qt Virtual Keyboard as you
can then leverage the shadow build functionality and rapidly switch between
build targets.
\section2 Configuration Options
The table below contains the top-level options for configuring the virtual
keyboard features.
\table
\header
\li CONFIG
\li Description
\li Remarks
\row
\li \e lang-<code>
\li Enables the specified language
\li The specified language can be activated using \e lang-<code> option, which
has the format "language[_country]", where:
\list
\li language is a lowercase, two-letter, ISO 639 language code
\li country is an uppercase, two-letter, ISO 3166 country code
\endlist
This option can be used to define the language support as required. The virtual
keyboard can support one or more languages at a time.
For example, \c CONFIG+=lang-fi_FI activates the Finnish language.
The virtual keyboard automatically includes all languages if no other languages
are specified.
\row
\li \e lang-all
\li Enables all the languages
\li Enables all the languages supported by the virtual keyboard. This flag is essentially
an alias for \c {CONFIG+="lang-ar_AR lang-da_DK ..."}
This option is enabled by default. To build only a specific language, use the
\c lang-<code> option above.
\row
\li \e handwriting
\li Enables handwriting input
\li This flag enables handwriting input using the first engine available at
build time in the following order: \c myscript, \c t9write, \c lipi-toolkit. To enable handwriting
input using a specific engine, use the feature-specific configuration instead.
For example, \c CONFIG+=lipi-toolkit.
\row
\li \e arrow-key-navigation
\li Enables arrow key navigation for the keyboard
\li Allows controlling the keyboard using the arrow and return keys.
\endtable
\section3 Advanced Configuration Options
The table below shows the advanced configuration options that will be applied
automatically when activating a certain top-level feature. The options can also be
used for enabling or disabling a specific feature.
In most cases, these options are not needed, but there are also cases where their use is
justified. For example, the Traditional Chinese language (CONFIG=lang-zh_TW) will include
both Zhuyin and Cangjie input methods by default. This behavior can be changed by adding
the preferred input method to the configuration, e.g., \c CONFIG+="lang-zh_TW zhuyin".
\table
\header
\li Advanced CONFIG
\li Top-level CONFIG
\li Description
\li Remarks
\row
\li \e disable-desktop
\li \e n/a
\li Disables Desktop integration
\li By default, the desktop integration is enabled when the target environment
is X11 or Windows desktop. With this option, the desktop integration can be
disabled.
\note For embedded integration, where the InputPanel is instantitated by
the application, there is no need to use this option explicitly. The virtual
keyboard will not create the desktop input panel if the application creates
InputPanel before the focus is set to an input field.
\row
\li \e disable-layouts
\li \e n/a
\li Disables built-in layouts
\li By default, the virtual keyboard plugin contains the English keyboard layout.
By specifiying the \e disable-layouts configuration flag, the built-in layout(s)
are excluded from the virtual keyboard plugin.
\note In this scenario, the \c QT_VIRTUALKEYBOARD_LAYOUT_PATH environment
variable should be set to the file system directory containing the custom keyboard
layouts before running the application.
\row
\li \e disable-xcb
\li \e n/a
\li Disables X11 integration
\li \note Deprecated since 1.3. Use \e disable-desktop instead.
\row
\li \e disable-hunspell
\li \e n/a
\li Disables Hunspell integration
\li Hunspell integration is enabled if the Hunspell library is available on the
system, or if it is built using the local project file. Integration can be
disabled using this option.
\row
\li \e no-bundle-pinyin
\li \e n/a
\li Disables bundling of pinyin resources
\li This option excludes pinyin resources from the plugin binary. This option may be
used to reduce the plugin binary size.
\row
\li \e no-bundle-tcime
\li \e n/a
\li Disables bundling of tcime resources
\li This option excludes tcime resources from the plugin binary. This option may be
used to reduce the plugin binary size.

\endtable
\section2 Building Documentation
\table
\row
\li \e {make docs}
\li Generates documentation
\endtable
\section2 Hunspell Integration
By default, \e HunspellInputMethod will not be available unless the Hunspell
library and development headers are found. For Linux/X11 targets, the Hunspell
library can be provided by installing the libhunspell-dev package.
Alternatively, the Hunspell sources can be extracted into the
\e src/plugins/hunspell/3rdparty/hunspell directory. The sources are automatically
detected by the qmake and the project will be configured to use the local Hunspell.
If Hunspell sources are used, then the dictionary files must also be
copied into the \e src/plugins/hunspell/3rdparty/hunspell/data directory.
An example of how the directory structure should look after copying in the
Hunspell sources and dictionary files is listed below:
\badcode
3rdparty
└── hunspell
├── data
│ ├── en_GB.aff
│ └── en_GB.dic
├── hunspell.pro
└── src
└── hunspell
├── affentry.cxx
├── affentry.hxx
(etc.)
\endcode
\section2 T9 Write Integration
T9 Write integration supports the T9 Write Alphabetic and T9 Write CJK engines. Both
engines are integrated via T9WriteInputMethod. The input method can be initialized
with either of the engines at runtime. The engine selection happens automatically
based on input locale and input mode from the keyboard.
\section3 T9 Write Compatibility
Qt Virtual Keyboard is compatible with T9 Write v7.5.0 onward.
The latest tested version is v7.8.1.
\section3 T9 Write Build Preparations
The contents of the SDK must be either manually copied to the directory structure
described below, or by using the \e unpack.py script found in the t9write directory.
To unpack the SDK using the script:
\badcode
$ cd src/plugins/t9write/3rdparty/t9write/
$ python unpack.py T9Write_Alpha_v7-8-0_SDK.zip .
\endcode
\badcode

\endcode
\note The above files are from the T9 Write demo SDK for Windows; the contents may vary for other
platforms.
Where the contents of each directory are:
\table
\header
\li Directory
\li Description
\li Remarks
\row
\li \e api
\li This directory should contain all of the API files
\li The API files usually located in the "api" and "public" directories
of the SDK, but sometimes in the "demo" directory.
When using both Alphabetic and CJK engines at the same time, any
overlapping files can be copied from either SDK.
\row
\li \e data
\li This directory should contain all HWR databases and optionally
XT9 databases.
\li HWR database for the T9 Write Alphabetic:
\list
\li \e _databas_le.bin
\endlist
HWR database for the T9 Write CJK:
\list
\li \e cjk_HK_std_le.hdb HongKong Chinese
\li \e cjk_J_std_le.hdb Japanese
\li \e cjk_K_mkt_le.hdb Korean
\li \e cjk_S_gb18030_le.hdb Simplified Chinese
\li \e cjk_T_std_le.hdb Traditional Chinese
\endlist
Language database:
\list
\li File extension is either \e .ldb or \e .phd
\endlist
\row
\li \e lib/<target>/<linkage>/<engine-variant>
\li Directory structure holding supported target builds.
\li These directories should hold the desired target libraries.
If both shared and static libraries are found, shared libraries
are preferred.
For example, to enable a static win32 build, copy
\e t9write_alphabetic_rel.obj to \e lib/win32/static/alphabetic
directory.
\endtable
Finally, the SDK is included in the build by adding CONFIG+=t9write to the
qmake command line.
\section2 MyScript Text SDK Integration
MyScript Text is designed for building applications that enable the recognition of
handwritten text. MyScript Text supports the recognition of isolated characters, cursive,
print and superimposed writing.
MyScript superimposed writing is integrated into Qt Virtual Keyboard. It enables
the recognition of letters, words or parts of words written one over the other,
without any explicit separation between consecutive fragments. It is capable of running
on memory and CPU constrained devices.
\section3 Input handwriting styles of MyScript Text SDK
The end-user can write one word fragment over the other, or one character over the other,
as depicted below. Space between two written words are automatically added, so that there
is no need for an explicit gesture.

\section3 Setting the Certificate of MyScript Text SDK
\b {A valid certificate is mandatory to use the MyScript Text SDK.} This is a
security measure that uniquely identifies you as a legitimate customer of MyScript
technologies. The certificate helps MyScript trace customers' identify and the products
that have been purchased.
The certificate is delivered in the /c [your_login].vo.zip package. When you unzip
this package, the certificate is automatically put in the appropriate location.
This ensure that the certificate is instantly working within the services and code
samples that you have been provided with.
\section3 How to build Qt Virtual Keyboard with MyScript Text SDK
The MyScript Text SDK is included in the build of Qt Virtual Keyboard by either
adding \c CONFIG+=handwriting or \c CONFIG+=myscript to the qmake command line.
\section2 Static builds
The virtual keyboard can be built and linked statically against the application.
This implies that Qt is also built statically (using the -static option in the
configure command line).
Static builds of the virtual keyboard are enabled by adding \c CONFIG+=static to
the qmake command line and then rebuilding.
Some third party modules used by the virtual keyboard are always built as shared
libraries. These modules are Hunspell and Lipi Toolkit.
\section3 Using the static plugin
The following section should be added to the application project file that uses the
statically built virtual keyboard.
\code
static {
QTPLUGIN += qtvirtualkeyboardplugin
QT += svg
}
\endcode
\c QTPLUGIN causes qmake to pull linker dependencies for the virtual keyboard
plugin. The SVG module is required as an extra dependency for Qt, since the SVG format is
required by the default styles.
From here on, using a statically built virtual keyboard is no different from the normal
case.
\section1 Deployment
\section2 Desktop Targets
Add a Deploy Step that executes the \e {make install} command, then deploy using
the \e {Deploy All} command.
\section2 Boot2Qt Targets
The installation is done by copying the necessary files to the memory card, or
by using the adb push command.
