[Interest] keyPressEvent on subclass of QPlainTextEdit

[nus1998]

Hi All,

I have some questions on keyPressEvent on sub-class of QPlainTextEdit, for the code attached below.
If I press '(', '{', or '[', these keys will be displayed in the edit. qDebug outputs 16777248  (value of Shift) for '(' and '{',  and outputs nothing for '['.
if I press any other key, they will be printed correctly and not displayed in the edit.

What's the problem for that?

my env: Qt 5.6.2 minGW version on win10 x64.

Best regards
Nus
