ProgressBar appearance change after deploying application

[Amazonasmann]

Hi,
my QProgressBar changes appearance after I deploy my application (By deploying I mean copying all necessary dlls and .exe file to some other PC).

In Qt Creator:

After Deploy:

I have an empty qt.conf file next to my .exe file and copy some DLLs ( /platforms/qwindows.dll ) to the folder of my executable.
I assume that I am missing some theme or DLL to achieve what I want.
What do I need to deploy with my .exe to get the "green progressbar" ?

Hi,

Did you already use windeployqt ?

[Amazonasmann]

Hi,
no I did not use windeployqt ( I didn't know what this is tbh). A quick google search showed me the documentation which raises a question: Can I use this with CMake?

@amazonasmann as it is a standalone console application and you pass the finished executable as a parameter, I see no reason why the original build system should matter

Thank you @SGaist I found my solution. I used windeployqt to copy all necessary DLLs and as it turns out I was missing the "styles/qwindowsvistastyle.dll" (This is just a guess but most probably this is the case).

In CMake I added the following:

# Retrieve the absolute path to qmake and then use that path to find
# the binaries
get_target_property(_qmake_executable Qt5::qmake IMPORTED_LOCATION)
get_filename_component(_qt_bin_dir "${_qmake_executable}" DIRECTORY)
find_program(WINDEPLOYQT_EXECUTABLE windeployqt HINTS "${_qt_bin_dir}")

add_custom_command(TARGET MyApp POST_BUILD
    COMMAND "${CMAKE_COMMAND}" -E
        env PATH="${_qt_bin_dir}" "${WINDEPLOYQT_EXECUTABLE}"
            "$<TARGET_FILE:MyApp>"
    COMMENT "Running windeployqt..."
)

Which adds all necessary dependencies to the folder.
