提要

當多人合作開發一個項目的時，若每人創建一個工程，就會出現同一個項目中多個pro文件。pri文件就是解決多個pro文件的一種方式，方便了最后代碼的合并。

示例

1.如何建立pri文件
2.pri文件與pro文件之間的聯系怎樣建立

如何建立pri文件

創建一個項目，在項目文件夾下創建一個文本文件，即txt文件，創建后修改其名稱為xxx.pri;

.pri文件與pro文件之間的聯系怎樣建立

繼上面創建好項目和pri文件后，用QtCreate打開項目，進入.pro文件，假如你的pro文件是這樣的；

QT += core guigreaterThan(QT_MAJOR_VERSION, 4): QT += widgetsCONFIG += c++11# The following define makes your compiler emit warnings if you use # any Qt feature that has been marked deprecated (the exact warnings # depend on your compiler). Please consult the documentation of the # deprecated API in order to know how to port your code away from it. DEFINES += QT_DEPRECATED_WARNINGS# You can also make your code fail to compile if it uses deprecated APIs. # In order to do so, uncomment the following line. # You can also select to disable deprecated APIs only up to a certain version of Qt. #DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000 # disables all the APIs deprecated before Qt 6.0.0SOURCES += \main.cpp \largescreenlistwidget.cppHEADERS += \dataStruct.h \largescreenlistwidget.hFORMS += \largescreenlistwidget.ui# Default rules for deployment. qnx: target.path = /tmp/$${TARGET}/bin else: unix:!android: target.path = /opt/$${TARGET}/bin !isEmpty(target.path): INSTALLS += targetDISTFILES +=

可以看到pro文件包含了源文件，頭文件，ui文件，此時將源文件，頭文件，ui文件部分，剪切下來粘貼到pri文件中。
下面是pri文件的內容：

SOURCES += \main.cpp \largescreenlistwidget.cppHEADERS += \dataStruct.h \largescreenlistwidget.hFORMS += \largescreenlistwidget.ui

pri文件保存之后，進入到pro文件，將其內容改為以下：

QT += core guigreaterThan(QT_MAJOR_VERSION, 4): QT += widgetsCONFIG += c++11# The following define makes your compiler emit warnings if you use # any Qt feature that has been marked deprecated (the exact warnings # depend on your compiler). Please consult the documentation of the # deprecated API in order to know how to port your code away from it. DEFINES += QT_DEPRECATED_WARNINGS# You can also make your code fail to compile if it uses deprecated APIs. # In order to do so, uncomment the following line. # You can also select to disable deprecated APIs only up to a certain version of Qt. #DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000 # disables all the APIs deprecated before Qt 6.0.0include(largescreenlistwidget.pri)# Default rules for deployment. qnx: target.path = /tmp/$${TARGET}/bin else: unix:!android: target.path = /opt/$${TARGET}/bin !isEmpty(target.path): INSTALLS += targetDISTFILES +=

相比于之前的pro文件，此時的pro文件將pri文件的 內容包含了進來，實際上相當于將之前的源文件，頭文件，ui文件放在了pri文件，將pri文件當作了頭文件一樣被包含進來。即之前包含的源文件，頭文件，ui文件部分，變為了include(largescreenlistwidget.pri)。
