8 Finding and Using Qt4
9 ^^^^^^^^^^^^^^^^^^^^^
11 This module can be used to find Qt4.  The most important issue is that
12 the Qt4 qmake is available via the system path.  This qmake is then
13 used to detect basically everything else.  This module defines a
14 number of :prop_tgt:`IMPORTED` targets, macros and variables.
16 Typical usage could be something like:
18 .. code-block:: cmake
20    set(CMAKE_AUTOMOC ON)
21    set(CMAKE_INCLUDE_CURRENT_DIR ON)
22    find_package(Qt4 4.4.3 REQUIRED QtGui QtXml)
23    add_executable(myexe main.cpp)
24    target_link_libraries(myexe Qt4::QtGui Qt4::QtXml)
26 .. note::
28  When using :prop_tgt:`IMPORTED` targets, the qtmain.lib static library is
29  automatically linked on Windows for :prop_tgt:`WIN32 <WIN32_EXECUTABLE>`
30  executables. To disable that globally, set the
31  ``QT4_NO_LINK_QTMAIN`` variable before finding Qt4. To disable that
32  for a particular executable, set the ``QT4_NO_LINK_QTMAIN`` target
33  property to ``TRUE`` on the executable.
35 Qt Build Tools
36 ^^^^^^^^^^^^^^
38 Qt relies on some bundled tools for code generation, such as ``moc`` for
39 meta-object code generation, ``uic`` for widget layout and population,
40 and ``rcc`` for virtual filesystem content generation.  These tools may be
41 automatically invoked by :manual:`cmake(1)` if the appropriate conditions
42 are met.  See :manual:`cmake-qt(7)` for more.
44 Qt Macros
45 ^^^^^^^^^
47 In some cases it can be necessary or useful to invoke the Qt build tools in a
48 more-manual way. Several macros are available to add targets for such uses.
52   macro QT4_WRAP_CPP(outfiles inputfile ... [TARGET tgt] OPTIONS ...)
53         create moc code from a list of files containing Qt class with
54         the Q_OBJECT declaration.  Per-directory preprocessor definitions
55         are also added.  If the <tgt> is specified, the
56         INTERFACE_INCLUDE_DIRECTORIES and INTERFACE_COMPILE_DEFINITIONS from
57         the <tgt> are passed to moc.  Options may be given to moc, such as
58         those found when executing "moc -help".
63   macro QT4_WRAP_UI(outfiles inputfile ... OPTIONS ...)
64         create code from a list of Qt designer ui files.
65         Options may be given to uic, such as those found
66         when executing "uic -help"
71   macro QT4_ADD_RESOURCES(outfiles inputfile ... OPTIONS ...)
72         create code from a list of Qt resource files.
73         Options may be given to rcc, such as those found
74         when executing "rcc -help"
79   macro QT4_GENERATE_MOC(inputfile outputfile [TARGET tgt])
80         creates a rule to run moc on infile and create outfile.
81         Use this if for some reason QT4_WRAP_CPP() isn't appropriate, e.g.
82         because you need a custom filename for the moc file or something
83         similar.  If the <tgt> is specified, the
84         INTERFACE_INCLUDE_DIRECTORIES and INTERFACE_COMPILE_DEFINITIONS from
85         the <tgt> are passed to moc.
90   macro QT4_ADD_DBUS_INTERFACE(outfiles interface basename)
91         Create the interface header and implementation files with the
92         given basename from the given interface xml file and add it to
93         the list of sources.
95         You can pass additional parameters to the qdbusxml2cpp call by setting
96         properties on the input file:
98         INCLUDE the given file will be included in the generate interface header
100         CLASSNAME the generated class is named accordingly
102         NO_NAMESPACE the generated class is not wrapped in a namespace
107   macro QT4_ADD_DBUS_INTERFACES(outfiles inputfile ... )
108         Create the interface header and implementation files
109         for all listed interface xml files.
110         The basename will be automatically determined from the name
111         of the xml file.
113         The source file properties described for
114         QT4_ADD_DBUS_INTERFACE also apply here.
119   macro QT4_ADD_DBUS_ADAPTOR(outfiles xmlfile parentheader parentclassname
120                              [basename] [classname])
121         create a dbus adaptor (header and implementation file) from the xml file
122         describing the interface, and add it to the list of sources. The adaptor
123         forwards the calls to a parent class, defined in parentheader and named
124         parentclassname. The name of the generated files will be
125         <basename>adaptor.{cpp,h} where basename defaults to the basename of the
126         xml file.
127         If <classname> is provided, then it will be used as the classname of the
128         adaptor itself.
133   macro QT4_GENERATE_DBUS_INTERFACE( header [interfacename] OPTIONS ...)
134         generate the xml interface file from the given header.
135         If the optional argument interfacename is omitted, the name of the
136         interface file is constructed from the basename of the header with
137         the suffix .xml appended.
138         Options may be given to qdbuscpp2xml, such as those found when
139         executing "qdbuscpp2xml --help"
144   macro QT4_CREATE_TRANSLATION( qm_files directories ... sources ...
145                                 ts_files ... OPTIONS ...)
146         out: qm_files
147         in:  directories sources ts_files
148         options: flags to pass to lupdate, such as -extensions to specify
149         extensions for a directory scan.
150         generates commands to create .ts (via lupdate) and .qm
151         (via lrelease) - files from directories and/or sources. The ts files are
152         created and/or updated in the source tree (unless given with full paths).
153         The qm files are generated in the build tree.
154         Updating the translations can be done by adding the qm_files
155         to the source list of your library/executable, so they are
156         always updated, or by adding a custom target to control when
157         they get updated/generated.
162   macro QT4_ADD_TRANSLATION( qm_files ts_files ... )
163         out: qm_files
164         in:  ts_files
165         generates commands to create .qm from .ts - files. The generated
166         filenames can be found in qm_files. The ts_files
167         must exist and are not updated in any way.
172   macro QT4_AUTOMOC(sourcefile1 sourcefile2 ... [TARGET tgt])
173         The qt4_automoc macro is obsolete.  Use the CMAKE_AUTOMOC feature instead.
174         This macro is still experimental.
175         It can be used to have moc automatically handled.
176         So if you have the files foo.h and foo.cpp, and in foo.h a
177         a class uses the Q_OBJECT macro, moc has to run on it. If you don't
178         want to use QT4_WRAP_CPP() (which is reliable and mature), you can insert
179         #include "foo.moc"
180         in foo.cpp and then give foo.cpp as argument to QT4_AUTOMOC(). This will
181         scan all listed files at cmake-time for such included moc files and if it
182         finds them cause a rule to be generated to run moc at build time on the
183         accompanying header file foo.h.
184         If a source file has the SKIP_AUTOMOC property set it will be ignored by
185         this macro.
186         If the <tgt> is specified, the INTERFACE_INCLUDE_DIRECTORIES and
187         INTERFACE_COMPILE_DEFINITIONS from the <tgt> are passed to moc.
192  function QT4_USE_MODULES( target [link_type] modules...)
193         This function is obsolete. Use target_link_libraries with IMPORTED targets
194         instead.
195         Make <target> use the <modules> from Qt. Using a Qt module means
196         to link to the library, add the relevant include directories for the
197         module, and add the relevant compiler defines for using the module.
198         Modules are roughly equivalent to components of Qt4, so usage would be
199         something like:
200          qt4_use_modules(myexe Core Gui Declarative)
201         to use QtCore, QtGui and QtDeclarative. The optional <link_type> argument
202         can be specified as either LINK_PUBLIC or LINK_PRIVATE to specify the
203         same argument to the target_link_libraries call.
206 IMPORTED Targets
207 ^^^^^^^^^^^^^^^^
209 A particular Qt library may be used by using the corresponding
210 :prop_tgt:`IMPORTED` target with the :command:`target_link_libraries`
211 command:
213 .. code-block:: cmake
215   target_link_libraries(myexe Qt4::QtGui Qt4::QtXml)
217 Using a target in this way causes :cmake(1)` to use the appropriate include
218 directories and compile definitions for the target when compiling ``myexe``.
220 Targets are aware of their dependencies, so for example it is not necessary
221 to list ``Qt4::QtCore`` if another Qt library is listed, and it is not
222 necessary to list ``Qt4::QtGui`` if ``Qt4::QtDeclarative`` is listed.
223 Targets may be tested for existence in the usual way with the
224 :command:`if(TARGET)` command.
226 The Qt toolkit may contain both debug and release libraries.
