.hpp header files not shown in projects view

[SGaist]

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The first thing would be to update Qt Creator to a more recent version. 7 is really outdated.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

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 ?

[Omar Hatem]

@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...

[Omar Hatem]

@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
