CCS/AM3358: Ctrl key issue in Qt

Part Number: AM3358

Tool/software: Code Composer Studio

hello,everyone:

       I used QT to design a program to identify a combination of keys.

       For example, Ctrl+1, Ctrl+2, Ctrl+3, Ctrl+4 and so on, the program works normally under Windows and receives the corresponding ASCII characters of 49, 50, 51, 52.

       But in the system designed with am3358 core board, the corresponding ASCII acceptance characters of 40, 59, 92, 93.

       Which reasons may cause the above phenomenon?

                                                               thank you !
