Qt Study 05 Qt Creator Project introduction

Qt Creator engineering management

• Qt Creator With The way of the project Manage the source code

• One Qt Creator The project includes Different types of The file of ：

  .pro Project description file ( important )

  .pro.user User profile ( Is not important )

  .h The header file

  .cpp Source file

  .ui Interface description file

  Resource file ( picture , Audio , etc. )

.pro Project description file

• .pro The basic composition of the project description document

  # - Comment start character

  QT - Module declaration

  TARGET - Executable file name

  TEMPLATE - Program template declaration ( Whether to generate dynamic library or executable file )

  SOURCE - Source file declaration

  HEADERS - Header file declaration

  FORMS - See statement for interface document

  RC_FILE - Resource file declaration

• .pro Advanced variables in the project description file

  INCLUDEPATH - Header file search path

  CONFIG - Set the configuration and compilation options for the project

  LIBS - Add third party library files

  DEFINES - Define compilation macro

CONFIG To configure

• CONFIG Used to set the project Configuration information and Compilation options

• CONFIG Common options for

  debug - structure debug Version of the executable

  release - structure release Version of the executable

  debug_and_release - At the same time build debug Version and release edition

  warn_on - Output as many warning messages as possible

  warn_off - Do not output warning messages

.pro The nature of the document is Qt Medium Makefile file ！

.pro The nature of the document

Project documents

Generally speaking , The descriptions in the project file are Using relative paths

And the relative path is Relative to the project file itself for

Qt Creator take Project documents As Target file

Be careful ：

1.Qt Creator When the project file is opened, a .pro.user file

2…pro.user The file contains some information related to Qt Related configuration information

3. When you need to move items between different computers , It is suggested to delete .pro.user file

Concepts in engineering

• structure (build)

  For All files are compiled , Final Generate executable

• Debug edition

  Sure Program debugging Build version of

  The executable program contains debugging information , The operation efficiency is not high

• Release edition

  Final release Build this version of the application

  No debug information , High operational efficiency
