+Tool Description
+================
+
+This tool helps with finding Qt4 tools and libraries,
+and also provides syntactic sugar for using Qt4 tools.
+
+The following snippet illustrates the tool usage::
+
+ def options(opt):
+ opt.load('compiler_cxx qt4')
+
+ def configure(conf):
+ conf.load('compiler_cxx qt4')
+
+ def build(bld):
+ bld(
+ features = 'qt4 cxx cxxprogram',
+ uselib = 'QTCORE QTGUI QTOPENGL QTSVG',
+ source = 'main.cpp textures.qrc aboutDialog.ui',
+ target = 'window',
+ )
+
+Here, the UI description and resource files will be processed
+to generate code.
+
+Usage
+=====
+
+Load the "qt4" tool.
+
+You also need to edit your sources accordingly:
+
+- the normal way of doing things is to have your C++ files
+ include the .moc file.
+ This is regarded as the best practice (and provides much faster
+ compilations).
+ It also implies that the include paths have beenset properly.
+
+- to have the include paths added automatically, use the following::
+
+ from waflib.TaskGen import feature, before_method, after_method
+ @feature('cxx')
+ @after_method('process_source')
+ @before_method('apply_incpaths')
+ def add_includes_paths(self):
+ incs = set(self.to_list(getattr(self, 'includes', '')))
+ for x in self.compiled_tasks:
+ incs.add(x.inputs[0].parent.path_from(self.path))
+ self.includes = sorted(incs)
+
+Note: another tool provides Qt processing that does not require
+.moc includes, see 'playground/slow_qt/'.
+
+A few options (--qt{dir,bin,...}) and environment variables
+(QT4_{ROOT,DIR,MOC,UIC,XCOMPILE}) allow finer tuning of the tool,
+tool path selection, etc; please read the source for more info.
