Function Keys as Shortcut Sequences

twall

Hello, I'm working on an application that will be fully driven by the keyboard (in QML). This will be on an embedded device that has a keypad that uses the (linux) keyboard driver. However, there will be an option for the user to plug in a keyboard for themselves too. To prevent accidental keyboard button presses, I thought that I'd put the shortcuts that drive my program onto the function row. F1 through F15. I noticed that when I do:

        Shortcut {
            id: f1
            context: Qt.WindowShortcut
            sequence: 1 
            onActivated: {
                console.log("f1")
            }
        }

It works. However, when I use any other function key (say F2), the Shortcut does not register. What can I do to make it register?

@twall Can we see the code for Shortcut? Your problem is more than likely in there.

I'm not great with QML but from what I can see there is no QML Shortcut object. I could have missed it but even when I tried to duplicate your problem I get:

file:///home/mike/test.qml:4 Shortcut is not a type

I'm surprised that it works at all, the sequence for F-Keys should be 'F1' or 'F2' etc

however you can summ up different keys to the same onActivated action this way:

Shortcut{
        sequence: "F1,F2,F3"
        onActivated: console.log("FKey 1 and 2 and 3 were pressed after each other")
    }

//This one you're looking for
    Shortcut{
        sequences: ["F1","F2", "F3"]
        onActivated: console.log("FKey 1 or 2 or 3 was pressed")
    }

It's a QtQuick 2.7 type.

@J-Hilk Thank you so much! I feel like a goof.

Lol yep, I missed it when I searched. And in my test I only used QtQuick 2.1.
