add EXE Icon

[Joe von Habsburg]

I want to add exe icon with cmake. I use qtcreator and I can give icon to mainwindow but I want to set to exe. How could I do it?

This is platform-dependent and is described here:

• https://doc.qt.io/qt-6/appicon.html

@Pl45m4 yes I read there but I do not understand.

firstly I create rc file also I have qrc file and, I add that line the rc file.

IDI_ICON1               ICON    "Resources/images/myappico.ico"

.After rc file will be added to cmake.

  set(APP_ICON_RESOURCE_WINDOWS "${CMAKE_CURRENT_SOURCE_DIR}/qt5app.rc")
    add_executable(qt5app main.cpp ${APP_ICON_RESOURCE_WINDOWS})

(That step create new layer on project)

It is very complex and not understanable. Is my step right ?

@Joe-von-Habsburg said in add EXE Icon:

IDI_ICON1 ICON "Resources/images/myappico.ico"

This is from the guide's qmake section
[Edit: but it's an overall resource example actually]

This:

    set(app_icon_resource_windows "${CMAKE_CURRENT_SOURCE_DIR}/resources/photosurface.rc")
    qt_add_executable(photosurfaceexample main.cpp ${app_icon_resource_windows})

and a resource file which contains your icon should work with cmake.

How you create the resource file is also linked and explained here:

• https://learn.microsoft.com/en-us/windows/win32/menurc/about-resource-files

Just read that you only use QtCreator and not Visual Studio.

photosurface.rc

what is that mean ? I realy do not know. I have .ico file. and how can I convert my ico file to rc file.

This was the example from here:

• https://doc.qt.io/qt-6/appicon.html#using-cmake-on-windows

The Microsoft link is only relevant, when you use Visual Studio to create your resource file.

Even this is in the qmake section, I think it will work for you as .rc file

IDI_ICON1     ICON    "path/to/myappico.ico"

@Pl45m4 could you give code example or command example ? I could not :(

This is actually right. Did you not make it?
Not quite understand your qrc part though, rc file and qrc file are totally irrelevant.

Yes I did now :)

Thank you so much for your helping

IDI_ICON1               ICON    "Resources/images/myapp.ico"

.rc file has been created by notepad

set(APP_ICON_RESOURCE_WINDOWS "${CMAKE_CURRENT_SOURCE_DIR}/icon.rc")

if(${QT_VERSION_MAJOR} GREATER_EQUAL 6)
    qt_add_executable(MyApp
        MANUAL_FINALIZATION
        ${PROJECT_SOURCES}
        ${QM_FILES}
        ${APP_ICON_RESOURCE_WINDOWS}
        ...
        icon.rc
