如何在Qt Creator中导入图标资源

本文主要描述如何在Qt Creator中创建资源文件，并的打入导入图标文件。

查看图标资源文件时，可以在项目的工程文件上鼠标单击右键-Open With-资源编辑器，效果如下图所示：

在项目的工程文件上鼠标单击右键-Open With-普通文本编辑器，效果如下图所示：

如果需要导入已经存在的资源文件和图标文件，如saribbonresouce.qrc是已经存在的资源文件，icon是已经存在的图标文件，见下图所示，

如果需要导入已经存在的资源文件和图标文件，则只需要在项目的项目文件*.pro中最后添加如下蓝色标注的语句：

QT       += core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = MyRibbonWindow
TEMPLATE = app

# The following define makes your compiler emit warnings if you use
# any feature of Qt which has been marked as 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 you use 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 6.0.0

#配置本应用程序编译后的输出路径
CONFIG(debug, debug|release){
    DESTDIR = $$PWD/../bin_qt$$[QT_VERSION]_debug
}else {
    DESTDIR = $$PWD/../bin_qt$$[QT_VERSION]_release
}

SOURCES += 
        main.cpp 
        mainwindow.cpp

HEADERS += 
        mainwindow.h

FORMS += 
        mainwindow.ui

RESOURCES += 
    saribbonresouce.qrc 

#此处的$$PWD代表D:MyProjectMyRibbonDemoMyRibbonWindowMyRibbonWindow.pro文件所在的目录
include($$PWD/../SARibbonBar.pri)

之后，按下“Crtl+S”保存，Qt Creator就会自动扫描和导入图标资源。如果未自动加载，可将Qt Creator关闭后再重启，一般就可加载成功。
