Why can't Qt distinguish the hyphen and the minus key?-CodePudding

I'm reviewing some part of a project written with Qt:

void Editor::keyPressEvent(QKeyEvent* event)
{
    int key = event->key();

    switch (key) {
    case Qt::Key_Tab:
...

I've put a breakpoint at int key = event->key().

Now, I've notice that pressing the minus "-" on the keypad shows me in debug:

Pressed 'Minus' (key:45 vKey:65453)
Qt::Key_Minus (0x002d)

Then, pressing "-" (the hyphen on the hyphen/underscore key gives me:

Pressed 'Minus' (key:45 vKey:45)"
Qt::Key_Minus (0x002d)
1439241440

So they are definitely detected as different (judging from this "vKey" number) but the event is the same: "Key_Minus".

Why can't I get the "Key_hyphen" event? How could I solve this (maybe using this "vKey" number?

CodePudding user response：

Try

event->nativeVirtualKey();

and

event->nativeScanCode();
