解：

在add_executable()语句中添加资源文件

问题

(不在add_library()中)

无法设置主窗口图标.

笔记：

>当我不使用AUTORCC时,我遇到了一些编译问题：
QtCore / qglobal.h：没有这样的文件或目录.但是,我更喜欢AUTORCC作为一种更现代的CMake方法.
>如果没有AUTORCC(与提供的CMakeLists.txt不同)和Qt-4.6.2,则当前代码有效.
不同的CMakeLists.txt)

码

这是我项目的最小化代码.树：

@H_502_21@|- CMakeLists.txt |- main_window.hpp |- main_window.cpp |- main.cpp |- resources | - resources.qrc | - images | - logo.png

main_window.cpp

@H_502_21@#ifndef MAINWINDOW_HPP #define MAINWINDOW_HPP #include <QMainWindow> class MainWindow : public QMainWindow { Q_OBJECT public: MainWindow(); }; #endif

main_window.cpp

@H_502_21@#include "main_window.hpp" MainWindow::MainWindow() { // i tried ":/images.png",":/resources/images/logo.png",":/logo.png" setWindowIcon(QIcon(":images/logo.png")); }

main.cpp中

@H_502_21@#include <QApplication> #include "main_window.hpp" int main(int argc,char *argv[]) { QApplication app(argc,argv); app.setOrganizationName("Organization"); app.setApplicationName("Application Example"); MainWindow mainWin; mainWin.show(); return app.exec();

}

的CMakeLists.txt.

@H_502_21@cmake_minimum_required(VERSION 3.1) project(qt_project) set(CMAKE_AUTOMOC ON) set(CMAKE_AUTORCC ON) find_package(Qt4 4.6 required) set(QT_USE_QTGUI TRUE) set(QT_USE_QTXML TRUE) include(${QT_USE_FILE}) add_definitions(${QT_DEFINITIONS}) // NOTE: it would be more convenient to be able to add the // resource file here upon the creation of the library add_library(mylib main_window.cpp) // SOLVED // BEFORE: add_executable(qt_test main.cpp) add_executable(qt_test main.cpp resources/resources.qrc) target_link_libraries(qt_test mylib ${QT_LIBRARIES} )

资源/ resources.qrc

@H_502_21@<!DOCTYPE RCC><RCC version="1.0"> <qresource> <file>images/logo.png</file> </qresource> </RCC>

编辑

这是生成的qrc_resources.cxx

@H_502_21@#include <QtCore/qglobal.h> static const unsigned char qt_resource_data[] = { // /users/ddakop/dev/misc/qt/resources/images/logo.png // ... removed hex data }; static const unsigned char qt_resource_name[] = { // images // ... removed hex data // logo.png // ... removed hex data }; static const unsigned char qt_resource_struct[] = { // : 0x0,0x0,0x2,0x1,// :/images 0x0,// :/images/logo.png 0x0,0x12,}; QT_BEGIN_NAMESPACE extern Q_CORE_EXPORT bool qRegisterResourceData (int,const unsigned char *,const unsigned char *); extern Q_CORE_EXPORT bool qUnregisterResourceData (int,const unsigned char *); QT_END_NAMESPACE int QT_MANGLE_NAMESPACE(qInitResources_resources)() { QT_PREPEND_NAMESPACE(qRegisterResourceData) (0x01,qt_resource_struct,qt_resource_name,qt_resource_data); return 1; } Q_CONSTRUCTOR_FUNCTION(QT_MANGLE_NAMESPACE(qInitResources_resources)) int QT_MANGLE_NAMESPACE(qCleanupResources_resources)() { QT_PREPEND_NAMESPACE(qUnregisterResourceData) (0x01,qt_resource_data); return 1; } Q_DESTRUCTOR_FUNCTION(QT_MANGLE_NAMESPACE(qCleanupResources_resources))
