In the Keil ARM 4.6 version, the Functions window displays list of all opened c-files and it's functions normally, but since 4.7 version (5.0 have this trouble too!) the Functions window have a two files only: system_stm32Fxx.c and file contains the main() function. I know about right-click menu inside window, there is ok all with checkboxes.
It's a Bug or not (it's only on the my IDE or not???)
The checkbox "Scan current editor files" on the right-click menu have no effect.
I have specification: Only the files declared in Project Components in a Functions window are displayed normally.
If I'll write in the C-file text the string '#include <otherFile.c>', this file otherFile.c after compilation is displayed in window Project in the ain c-file as "included" - it's usual, normally. But this file does not wish to be displayed in the Functions window at the left tab, despite established checkbox "Scan current editor files" by the mouse left-click menu on the Functions window. The last MDK version where it works well is the 4.70a. All newer versions have this trouble.
This function was very convenient as to there are cases when it is required to include a code piece placed in a separate file which should be included in strictly certain place of the project and this file is used in set of different projects simultaneously and should be identical in all projects.
