Scancodes Windows Linux
-
Hi. I need to receive the current button clicked. Conditions: Linux\Win + any keyboard layout.
My code doesn't correct in Win:enum class Keys { F1 = 67, F2 = 68, F3 = 69, F4 = 70, F5 = 71, F6 = 72, F7 = 73, F8 = 74, F9 = 75, F10 = 76, F11 = 95, F12 = 96, CAPS = 66, LSHIFT = 50, RSHIFT = 62, LCTRL = 37, RCTRL = 105, LALT = 64, RALT = 108, ENTER = 36, BACKSPACE = 22, Q = 24, W = 25, E = 26, R = 27, T = 28, Y = 29, U = 30, I = 31, O = 32, P = 33, A = 38, S = 39, D = 40, F = 41, G = 42, H = 43, J = 44, K = 45, L = 46, Z = 52, X = 53, C = 54, V = 55, B = 56, N = 57, M = 58, LSqBracket = 34, RSqBracket = 35, VerticalLine = 51, COLON = 47, QuotationMark = 48, LAngleBracket = 59, RAngleBracket = 60, Question = 61, SlantLine = 106, Asterick = 63, Minus = 82, Plus = 86, NLEnter = 104, NLDel = 91, Zero = 19, One = 10, Two = 11, Three = 12, Four = 13, Five = 14, Six = 15, Seven = 16, Eight = 17, Nine = 18, NLZero = 90, NLOne = 87, NLTwo = 88, NLThree = 89, NLFour = 83, NLFive = 84, NLSix = 85, NLSeven = 79, NLEight = 80, NLNine = 81 };Values in Windows and Linux are different. This code only for Linux. If use QKeyEvent::key() for a different keyboard layout (for example - Russian layout) , then any key() below will be ignored (except Key_Escape):
void Form::keyPressEvent(QKeyEvent *e) { if(e->key() == Qt::Key_C){ buttonClicked("C"); return; } }How do solve this?

By taking a look into the documentation you will find enough functions which gives you a scan code instead the key.

@Christian-Ehrlicher I know it. But values in enum class Keys are QKeyEvent::nativeScanCode() const. It didn't work in Windows.

What does this mean? nativeScanCode() returns an uint32, not an enum...

void Form::keyPressEvent(QKeyEvent *e) { qDebug() << QString("Key=%1 Scan=%2").arg(e->text()).arg(e->nativeScanCode()); }and we'll receive these nums, which I wrote in enum.

I rewrote it for Win and Linux, but I'm sure there is a simpler solution.

@Evgeny-Siberia why enum?
const QMap<uint32,QString> keyNames = { {scancode1:"1"}, {scancode2:"2"}, ... }@artwaw
"why enum?" - I thought about this earlier but decided that enum is easy to read. I will use it in a project.switch (e->nativeScanCode()) { case static_cast<quint32>(Keys::F1): ...Here we can see that it was F1 that was pressed. For more convenient use.

@Evgeny-Siberia I fail to see the improvement of rewriting Qt::Keys - especially that those are already platform independent. You are, of course, most welcome to do as you wish.
EDIT:
I mean, there already isQt::key_F1, replacing it with key::whatever... But it's your code.For more information please re-read.
Kind Regards,
