@LeLev Thank you very much for your answer. It helped me to understand my issue a little more. So I tried your code, and it works, meaning that the ListView isn't eating the Space key.
However my interface is a little more complex than this one, it contains other objects like SwipeView, and yes, my items contain components like buttons which may take the focus. However I already tried to deactivate them and even thus the issue remained.
I played a while around the code you posted. I noticed that the following code no longer receives any key:
Rectangle
{
anchors.fill: parent
color: "transparent"
visible: true
SwipeView
{
anchors.fill: parent
activeFocusOnTab: false
Page
{
background: null
ListView
{
id: view
anchors.fill: parent
spacing: 2
focus: true
model: ListModel
{
ListElement
{
name: "el1"
}
ListElement
{
name: "el2"
}
ListElement
{
name: "el3"
}
}
delegate: Button
{
focus: false
focusPolicy: Qt.NoFocus
onFocusChanged: {if (focus) focus = false;}
width: parent.width
height: 50
text: index === view.currentIndex ? "currentIndex" : modelData
onClicked:
{
view.currentIndex = index
}
}
Keys.onPressed:
{
console.warn("key clicked");
if (event.key === Qt.Key_Space)
{
console.log("space clicked");
console.log(view.model.get(view.currentIndex).name); // view.model.get(ind).name = "new value"
event.accepted = true;
}
}
}
}
}
}
So I assume that some components operate like filters and may stop internally the keyboard signals, or at least a part of them, without let the choice to the developer to bypass this behavior (or at least I don't know how to do). To be honest I'm a little puzzled, because I worked for15 years with the Windows API before changing for Qt, and receiving a keyboard notification was never an issue, even when the parent component already received it before (in fact it was the contrary: the message could be blocked in the parent, but by default it was passing).
So now the question is: in the above code, how can I receive the keyboard signals, and in particular the Space key, in my ListView despite of the parent SwipeView? Or which solution is normally used in a such situation, e.g is there a way to globally listen the keyboard and intercept keys in the Windows level, BEFORE any component receives them?
