[Bug 1504755] Re: Popover does not open on top of all other Items
So, wrapping another Item around the example code above which serves as
the root item, the problem is not there. Also, when the root Item is a
MainView, the problem does not occur because the MainView places its
children in a separate default Item.
This makes the bug less urgent for now.

Title:
Popover does not open on top of all other Items
Status in ubuntu-ui-toolkit package in Ubuntu:
New
Bug description:
When I open a Popover, I expect it to be on top of all other Items.
This is not the case if any Item has a z-value > 0, the Popover will
then open behind that Item, potentially hiding the Popover.
Use the example code below to reproduce the issue. Run the qml code
and click the button at the bottom to open the popover behind the blue
rectangle.
Note that also the MouseArea in the blue rectangle eats the events of
the Popover's InverseMouseArea that is used to close the popover. So
if there is a MouseArea in an Item with z>1, this area cannot be
clicked to close the Popover.
import QtQuick 2.4
import Ubuntu.Components 1.3
import Ubuntu.Components.Popups 1.3
Item {
width: 600
height: 600
Rectangle {
anchors.centerIn: parent
color: "blue"
width: 400
height: 400
opacity: 0.8
z: 1
MouseArea { anchors.fill: parent }
}
Rectangle {
anchors {
right: parent.right
verticalCenter: parent.verticalCenter
}
width: 300
height: 300
color: "yellow"
}
Button {
id: button
anchors {
bottom: parent.bottom
horizontalCenter: parent.horizontalCenter
margins: 30
}
text: "Pop!"
onClicked: PopupUtils.open(popoverComponent, button)
Component {
id: popoverComponent
Popover {
Rectangle {
color: "green"
width: parent.width
height: 300
}
}
}
}
}
