Warning: This file is generated.

[JackMyson]

When I upgraded my Qt Creator to the newest, i.e. version 15.0.0, the CMake sub-directory indices are all disappeared. Also, when I click into the, let say, src as in add_subdirectory(${CMAKE_CURRENT_LIST_DIR}/src}), and typed in/ deleted something in the file, it popped up something like "Warning: This file is generated. Do not show again". Although it causes no harm to my project, it's very annoying.

Anyone knows if it is a normal phenomenon or not, for an upgraded Qt Creator?

(That is, I've never encountered any problems in Qt Creator v. 13 and 14.)

Thank in advance!

Hi,

It does look like something is off.
Can you provide a minimal projects that triggers this behavior in Qt Creator ?

./CMakeLists.txt

cmake_minimum_required(VERSION 3.16)

project(Testing VERSION 0.7.0 LANGUAGES CXX)

set(CMAKE_AUTOUIC ON)
set(CMAKE_AUTOMOC ON)

find_package(QT NAMES Qt6 Qt5 REQUIRED COMPONENTS Widgets)
find_package(Qt${QT_VERSION_MAJOR} REQUIRED COMPONENTS Widgets)

set(SOURCES "")

include_directories(${CMAKE_CURRENT_LIST_DIR}/src)

add_subdirectory(${CMAKE_CURRENT_LIST_DIR}/src)  # <- This file!!

if (${QT_VERSION_MAJOR} GREATER_EQUAL 6)
    qt_add_executable(Testing MANUAL_FINALIZATION ${SOURCES})

    if (ANDROID)
        add_library(Testing SHARED ${SOURCES})
    else()
        add_executable(Testing ${SOURCES})
    endif()

endif()

./src/CMakeLists.txt

set(SOURCES

# When I edit this file, it triggers

Thanks a lot!

Qt Creator 15 has changes regarding the project view. The CMake targets have their defining CMakeLists.txt as a node.

The idea would be to have a quick access to the CMakeLists.txt that defined the target. And only the top CMakeLists.txt is being displayed.

All the rest CMakeLists.txt are marked as generated, that's why you get the annoying warning.

Please do open a bug report at https://bugreports.qt.io/secure/CreateIssue.jspa?pid=10512

I could think of an option or a variable set in the top CMakeListst.txt that would control how Qt Creator renders the project's view.

@cristian-adam Yes, you're absolutely correct. The best way to deal with this annoying thingy is just putting some check buttons inside Edit->Preferences->Environment or CMake->display/hide quick views. That would be great.

Anyway, am going to suggest doing so on the Bug Reporter. Thanks for the response.
