I use VSCodium and gcc complier to develop c++ in linux, clangd server and clangd vscode plugin have been installed. My example code is shown below.

QByteArray bytearray;
configFile.open(QIODevice::WriteOnly); //configFile is a QFile
configFile.write(bytearray);

Clangd doesn’t mark the open() function as incorrect, but it tells me that the call to write() is incorrect with the following error message.

No matching member function for call to 'write'clang(ovl_no_viable_member_function_in_call)
qiodevice.h(90, 12): Candidate function not viable: no known conversion from 'QFile' to 'QIODevice' for object argument
qiodevice.h(89, 12): Candidate function not viable: no known conversion from 'QFile' to 'QIODevice' for object argument
qiodevice.h(88, 12): Candidate function not viable: requires 2 arguments, but 1 was provided

The QFile class inherits QFileDevice which inherits QIODevice, so the write() function should also exist in QFile. But clangd seems to not recognize the function.
In qiodevice.h

qint64 write(const char *data, qint64 len);
qint64 write(const char *data);
qint64 write(const QByteArray &data);

I included the qiodevice.h and qfiledevice.h but nothing changed.

I want the clangd language server to give correct message, help me ,thanks.
