QMake 和 Uic

qmake 和 uic都很好用 qmake用来生成makefile文件 然后交给编译器来进行编译 uic将QtDesigner生成的ui文件解析成ui_uifilename.h文件（user interface complier）

uic：
Description


This page documents the User Interface Compiler for the Qt GUI toolkit.The uic reads a user interface definition (.ui) file in XML asgenerated by Qt Designer and creates corresponding C++ header or sourcefiles. It also generates an image file that embeds raw image data inC++ source code.

Generate declaration:
uic [options] <file>
Generate implementation:
uic [options] -impl <headerfile> <file>
<headerfile>: name of the declaration file

Generate image collection:
uic [options] -embed <project> <image1> <image2> <image3> ...
<project>: project name <image[1..n]>: image files

For convenience, uic can also generate declaration or implementation stubs for subclasses.

Generate subclass declaration:
uic [options] -subdecl <subclassname> <baseclassheaderfile> <file>
<subclassname>: name of the subclass to generate
<baseclassheaderfile>: declaration file of the baseclass

Generate subclass implementation:
uic [options] -subimpl <subclassname> <subclassheaderfile> <file>
<subclassname>: name of the subclass to generate
<subclassheaderfile>: declaration file of the subclass
General Options

-o file
Write output to file rather than to stdout.
-nofwd

Omit forward declarations of custom classes in the generated header file. This is necessary if typedef classes are used.
-tr func
Use func() instead of tr() for internationalization.
-version
Display the version of uic and exit.
Usage

uic is almost always invoked by make(1), rather than by hand.

Here are useful makefile rules if you only use GNU make:
%.h: %.ui
uic $< -o $@
%.cpp: %.ui
uic -impl $*.h $< -o $@
If you want to write portably, you can use individual rules of the following form:
NAME.h: NAME.ui
uic $< -o $@
NAME.cpp: NAME.ui
uic -impl $*.h $< -o $@
You must also remember to add NAME.cpp to your SOURCES (substitute yourfavorite name) variable and NAME.o to your OBJECTS variable.

(While we prefer to name our C++ source files .cpp, the uic doesn'tcare, so you can use .C, .cc, .CC, .cxx or even .c++ if you prefer.)
