Hi, everyone. I stumbled across behavior which looks as a bug to me. Qt 5.7
import QtQuick 2.2
import QtQuick.Controls 1.1
ApplicationWindow {
visible: true
width: 2048/2
height: 1536/2
Rectangle {
id: big
x: 10
y: 20
width: 400
height: 400
MouseArea {
anchors.fill: parent
drag.target: parent
drag.filterChildren: true
Rectangle {
id: green
x: 30; y: 30
width: 100; height: 100
color: "green"
MouseArea {
anchors.fill: parent
}
}
Rectangle {
id: red
x: 200; y: 30
width: 100; height: 100
color: "red"
MouseArea {
anchors.fill: parent
onPressed: mouse.accepted = false
}
}
}
}
}
Basically, there's a large rectangle containing two small rectangles. Each
of them contains a mouse area, the big rectangle's mouse area is supposed
to make the big rectangle draggable, so drag.filterChildren is set to true
to intercept drags. The green rectangle's mouse area accepts mouse press
events, the red rectangle's mouse area is specifically told not to. The
result: I can drag the big rectangle by dragging the green rectangle, but I
can't do the same by dragging the red one. By looking at the source code I
concluded that the filtering mechanism relies on the fact that some item on
top of the mouse area receiving filtered events actually accepts press
events. This does not seem right to me, I want the big rectangle to be
dragged no matter how items on top handle mouse press events, what do you
think?
