Add anchors property to Popup to allow centering in parent/window
Currently, users must manually position their Popup using x and y
bindings:
Popup {
x: (parent.width - width) / 2
y: (parent.height - height) / 2
}
This patch adds an anchors property so that you can do this instead:
Popup {
anchors.centerIn: parent
}
It's also possible to conveniently center within the window from
anywhere within the scene (106e7b63 also documents an alternative way
of doing this using Overlay):
Window {
id: window
Pane {
Popup {
anchors.centerIn: window
}
}
}
QQuickAnchors were never used with Popup, because we cannot use the
QQuickAnchors implementation as-is, as the visual QQuickItem parent
is not the actual parent item of QQuickPopupItem.
Currently just centerIn is supported, as that's the most common
use case.
[ChangeLog][Controls][Popup] Added anchors.centerIn to Popup to allow
a covenient way of centering a popup.
