Adding qrc icon resource to a CMake Qt project

[Slei]

Hey,

I'm currently trying to add a icon to my cmake project, to be able to use it as SystemTrayIcon,
it works fine when using qmake via

Hierarchy:

resources.qrc
   /icons
         myicon.ico

.pro
RESOURCES += \
    resource.qrc

icon code: 
 auto icon = QIcon(":/icons/myicon.ico");

but it doesn't work with cmake using the following cmake commands:

qt5_add_resources(resource.qrc)

or

add_executeable(resource.qrc)

has anyone any idea what i'm doing wrong?

thanks

It must be qt5_add_resources(srcs_for_exe resource.qrc) and then later add_executable(... ${srcs_for_exe})
See http://doc.qt.io/qt-5/cmake-manual.html#macro-reference

ok it generated a resource .cpp now with all the icon data, which seems to be good. bit it still doen't display an icon in the systemtray so something else might be wrong

Hi,

Did you ensure that the generated cpp file gets compiled and linked properly ?

[Slei]

do I have to do anything special with cmake or should this be done automatically with one of those

	set(CMAKE_AUTOMOC ON)
	set(CMAKE_AUTORCC ON)
	set(CMAKE_AUTOUIC ON)

[Slei]

i probably should add that I'm currently using a source build, maybe the there is no .ico support by default?
but I've alos tried it with png and jpg

Can you show your CMakeList.txt file ?

I've tried it with GLOB for qrc or directly adding a qrc to the executable (custom cmake function in my case)

/       file(GLOB source_files *.c *.cpp *.qrc)
       file(GLOB header_files *.h *.hpp *.txt)

	set(CMAKE_INCLUDE_CURRENT_DIR ON)
	set(CMAKE_AUTOMOC ON)
	set(CMAKE_AUTORCC ON)
	set(CMAKE_AUTOUIC ON)
	find_package(Qt5Widgets REQUIRED)
	find_package(Qt5WebEngineWidgets REQUIRED)
	find_package(Qt5WebChannel REQUIRED)


	qt5_add_resources(COLYOO_QT_RESOURCES app.qrc web.qrc)

	message(STATUS "SLEIDEBUG:${COLYOO_QT_RESOURCES}")


       # add the GUI WIN32 executable
       cyo_add_executable(${PROJECT_NAME} WIN32 ${source_files} ${header_files} chatwidget.ui ${COLYOO_QT_RESOURCES})

if you have set(CMAKE_AUTORCC ON) then there's no need to call qt5_add_resources just add your .qrc files to the list of sources for the target as they were .cpp files

[Slei]

@VRonin

I've heard about that but it still doesn't work :o

[Slei]

@VRonin do I still have to add it to the executable and GLOB it then? or is this also done automatically with the AUTORCC

[VRonin]

you don't have to GLOB it, you can GLOB it. You could also add .qrc files in the same way you are adding chatwidget.ui at the moment

ok i think it works now, for whatever reason I'll test it a few times to be 100% sure, thsi is my current cmakelists.txt

    # search all source and header files
    file(GLOB source_files *.c *.cpp *.qrc)
    file(GLOB header_files *.h *.hpp *.txt)

	set(CMAKE_INCLUDE_CURRENT_DIR ON)
	set(CMAKE_AUTOMOC ON)
	set(CMAKE_AUTORCC ON)
	set(CMAKE_AUTOUIC ON)
	find_package(Qt5Widgets REQUIRED)
	find_package(Qt5WebEngineWidgets REQUIRED)
	find_package(Qt5WebChannel REQUIRED)


	#qt5_add_resources(COLYOO_QT_RESOURCES app.qrc web.qrc)

	message(STATUS "SLEIDEBUG:${COLYOO_QT_RESOURCES}")


    # add the GUI WIN32 executable
    cyo_add_executable(${PROJECT_NAME} WIN32 ${source_files} ${header_files} chatwidget.ui ${COLYOO_QT_RESOURCES})

but i think i tried this version once before and it didn't work lol ._.
