[英]Qt resources files with CMake and AUTORCC
Solution : 方案 :
Add resource files in the add_executable()
statement 在add_executable()
语句中添加资源文件
(not in the add_library()
) (不在add_library()
)
Fail to set main window icon. 无法设置主窗口图标。
Notes : 备注 :
When I don't use AUTORCC
I run into some compilation problems: QtCore/qglobal.h: no such file or directory
. 当我不使用AUTORCC
我遇到了一些编译问题: QtCore/qglobal.h: no such file or directory
。 But, I do prefer AUTORCC as a more modern CMake approach. 但是,我更喜欢AUTORCC作为一种更现代的CMake方法。
Without the AUTORCC (different CMakeLists.txt than the provided) and Qt-4.6.2 the current code worked. 如果没有AUTORCC(与提供的CMakeLists.txt不同)和Qt-4.6.2,则当前代码无效。 different CMakeLists.txt) 不同的CMakeLists.txt)

I think you need to link qrc_resources generated file. 我认为你需要链接qrc_resources生成的文件。
I suppose you know the next info: 我想你知道下一个信息:
http://www.cmake.org/cmake/help/v3.0/manual/cmake-qt.7.html http://www.cmake.org/cmake/help/v3.0/manual/cmake-qt.7.html
Where you can see the next line: 在哪里可以看到下一行:
add_executable(myexe main.cpp resource_file.qrc)

I'm not sure if this is new or not, but I have figured out a way to add resources to libraries. 我不确定这是否是新的,但我已经想出了一种向库添加资源的方法。
In my library's CMakeLists.txt I have the following: 在我的图书馆的CMakeLists.txt中,我有以下内容:
list (APPEND RESOURCES library.qrc)
qt5_add_resources (RCC_SOURCES ${RESOURCES})
...
add_library(library ${RCC_SOURCES} ${SOURCES})
In the library, in one of my "main classes" (for me, this class was the first thing that gets created in the library and the last thing that gets destroyed), I did the following: 在库中,在我的一个“主类”中(对我来说,这个类是在库中创建的第一个东西,最后一个被破坏的东西),我做了以下内容:
class libClass : public QMainWindow {
Q_OBJECT
public:
libClass() : QMainWindow(nullptr, 0) {
Q_INIT_RESOURCE(library);
}
~libClass() {
Q_CLEANUP_RESOURCE(library);
}
};
