.hpp header files not shown in projects view

[Omar Hatem]

I am using qt creator version 7.0.
In any cmake project, when you have your header files written with extension ".hpp" it doesn't show up in the projects view in files tab.

However, if you rename your header file to be ".h" header file it will be shown. Is there any solution or work around to this ?

I just tested with Qt Creator 11.0.3 on macOS and the .hpp headers are properly shown.

Might be a silly question but did you also update the CMakeLists.txt file after renaming the header file ?

Hi and welcome to devnet,

The first thing would be to update Qt Creator to a more recent version. 7 is really outdated.

@SGaist Thank you for the reply. The reason why I am using this version is because I am developing on Linux (Ubuntu 20.04 LTS). The most recent versions of qt creator have a really annoying bug; when you run the a cpp target whether it's set to "run in terminal" or not, it freezes. you have to wait for like 5 secs or more before qt creator responds again.
In either way, the I tried the latest version, and it didn't show the ".hpp" files also.

@SGaist Actually it works in qt creator 11.0.3 on ubuntu 20.04 LTS. But I wonder Should I add the header files one by one in cmakelists.txt?

for example, this doesn't work.:

set(INC_DIRS ${CMAKE_CURRENT_SOURCE_DIR}/include)
add_executable(${PROJECT_NAME}  ${SOURCES} ${INC_DIRS})

but this works:

set (HEADERS ${CMAKE_CURRENT_SOURCE_DIR}/include/test.hpp)
add_executable(${PROJECT_NAME}  ${SOURCES} ${HEADERS})

@Omar-Hatem because add_executable() takes a list of source/header files, not directories as described in the documentation.

Should I add the header files one by one in cmakelists.txt?

Yes, the same goes for every source file.

[Omar Hatem]

@Christian-Ehrlicher So, I must add the header to the add_executable
fucntion in order to work? otherwise target_include_directories won't suffice to view the header files under the headers files filter in the project view?

[Christian Ehrlicher]

Correct. It would be very cumbersome if all headers from include_directories() would be shown there...

@Christian-Ehrlicher @SGaist Thank you guys!

[Omar Hatem]

@Christian-Ehrlicher I have a question please, just to make sure, is including the header files in add_executable function makes extra overhead during compilation?

[Christian Ehrlicher]

@Omar-Hatem No
