How do I to set a letter key to start an action? [Solved]

[Cold_Distance]

Hi, a stupid question here, but I was searching through Google and all answers I found are too old, for Qt 4.

I just need to set a letter key to move a simple square on a window, I prefer A, S, D, W because they are the standard, and I want to know it because my current code doesn't work when I run the program on a Android AVD with a physical keyboard, because it seems that the AVD doesn't detect the cursor keys.

Here's my code.

import QtQuick 2.3
Item{
    id: root


    Rectangle {
        id:cuadrado
        width: 150
        height: 150
        color: "#53a135"
        border.color: "#61e361"

    }

    // A partir de aquí podemos empezar a manipular el 'cuadrado' desde el teclado
    focus: true
    Keys.onLeftPressed: cuadrado.x -= 8
    Keys.onRightPressed: cuadrado.x += 8
    Keys.onUpPressed: cuadrado.y -= 8
    Keys.onDownPressed: cuadrado.y += 8
    Keys.onPressed: {
        switch(event.key) {
        case Qt.Key_Plus:
            cuadrado.scale += 0.2
            break;
        case Qt.Key_Minus:
            cuadrado.scale -= 0.2
            break;
        }
    }

}

This is one of the three files of the project, but the problem is here.

Well I discovered it myself.

import QtQuick 2.3
Item{
    id: root


    Rectangle {
        id:cuadrado
        width: 150
        height: 150
        color: "#53a135"
        border.color: "#61e361"

    }

    // A partir de aquí podemos empezar a manipular el 'cuadrado' desde el teclado
    focus: true
    //Keys.onLeftPressed: cuadrado.x -= 8
    //Keys.onRightPressed: cuadrado.x += 8
    //Keys.onUpPressed: cuadrado.y -= 8
    //Keys.onDownPressed: cuadrado.y += 8
    Keys.onPressed: {
        switch(event.key) {
        case Qt.Key_Plus:
            cuadrado.scale += 0.2
            break;
        case Qt.Key_Minus:
            cuadrado.scale -= 0.2
            break;
        case Qt.Key_A:
            cuadrado.x -= 8
            break;
        case Qt.Key_D:
            cuadrado.x += 8
            break;
        case Qt.Key_W:
            cuadrado.y -= 8
            break;
        case Qt.Key_S:
            cuadrado.y += 8
            break;
        }
    }

}

Sorry.
