[Bug 1484736] [NEW] Locked & Hidden Page header is shown briefly when returning to the page
Public bug reported:
While playing with U.C 1.3, I noticed the following bug with page
headers.
Assume you have a pagestack with 2 pages, rootPage and secondPage. The
rootPage header is locked and not visible. When you push secondPage and
then pop it, you will briefly notice the rootPage header being shown
which then slides out of view. This is rather every time the hide
animation is shown.
Affects ubuntu-clock-app which hides & locks the page header.
Here is a sample app to reproduce the bug:
import QtQuick 2.4
import Ubuntu.Components 1.3
MainView {
applicationName: "testheader.nik90"
width: units.gu(100)
height: units.gu(75)
PageStack {
id: mainStack
Component.onCompleted: push(rootPage)
Page {
id: rootPage
head {
visible: false
locked: true
}
Column {
anchors { left: parent.left; right: parent.right; top: parent.top; margins: units.gu(2) }
spacing: units.gu(2)
Label {
width: parent.width
wrapMode: Text.WordWrap
text: "Steps to reproduce bug:
1. Press \"Click Me\" button to push second page.
2. Press \"Back\" header button to go back to the root page
3. Notice how the root page header is shown briefly and then slides out of sight"
}
Button {
text: "Click Me"
color: UbuntuColors.green
anchors.horizontalCenter: parent.horizontalCenter
onClicked: mainStack.push(secondPage)
}
}
}
Page {
id: secondPage
title: "Second Page"
visible: false
}
}
}
