  11 Tool Description
  12 ================
  13
  14 This tool helps with finding Qt4 tools and libraries,
  15 and also provides syntactic sugar for using Qt4 tools.
  16
  17 The following snippet illustrates the tool usage::
  18
  19         def options(opt):
  20                 opt.load('compiler_cxx qt4')
  21
  22         def configure(conf):
  23                 conf.load('compiler_cxx qt4')
  24
  25         def build(bld):
  26                 bld(
  27                         features = 'qt4 cxx cxxprogram',
  28                         uselib   = 'QTCORE QTGUI QTOPENGL QTSVG',
  29                         source   = 'main.cpp textures.qrc aboutDialog.ui',
  30                         target   = 'window',
  31                 )
  32
  33 Here, the UI description and resource files will be processed
  34 to generate code.
  35
  36 Usage
  37 =====
  38
  39 Load the "qt4" tool.
  40
  41 You also need to edit your sources accordingly:
  42
  43 - the normal way of doing things is to have your C++ files
  44   include the .moc file.
  45   This is regarded as the best practice (and provides much faster
  46   compilations).
  47   It also implies that the include paths have beenset properly.
  48
  49 - to have the include paths added automatically, use the following::
  50
  51      from waflib.TaskGen import feature, before_method, after_method
  52      @feature('cxx')
  53      @after_method('process_source')
  54      @before_method('apply_incpaths')
  55      def add_includes_paths(self):
  56         incs = set(self.to_list(getattr(self, 'includes', '')))
  57         for x in self.compiled_tasks:
  58             incs.add(x.inputs[0].parent.path_from(self.path))
  59         self.includes = list(incs)
  60
  61 Note: another tool provides Qt processing that does not require
  62 .moc includes, see 'playground/slow_qt/'.
  63
  64 A few options (--qt{dir,bin,...}) and environment variables
  65 (QT4_{ROOT,DIR,MOC,UIC,XCOMPILE}) allow finer tuning of the tool,
  66 tool path selection, etc; please read the source for more info.
