Public bug reported:
When using 3 columns (each with a page) and resizing the window to 2 and
1 column, the middle column is empty after resizing to 3 columns again.
(The video may show this more clearly.)
Maybe I am just using this wrong.
Here is the code I used:
import QtQuick 2.4
import Ubuntu.Components 1.3
MainView {
objectName: "mainView"
applicationName: "apltest.mweber"
width: units.gu(100)
height: units.gu(75)
AdaptivePageLayout {
id: apl
anchors.fill: parent
primaryPage: page1
property bool thirdCol: false
layouts: [
PageColumnsLayout {
when: width > units.gu(140) && apl.thirdCol
// column #0
PageColumn {
minimumWidth: units.gu(30)
maximumWidth: units.gu(60)
preferredWidth: units.gu(40)
}
// column #1
PageColumn {
minimumWidth: units.gu(30)
maximumWidth: units.gu(60)
preferredWidth: units.gu(40)
}
// column #2
PageColumn {
fillWidth: true
}
},
PageColumnsLayout {
when: width > units.gu(80)
// column #0
PageColumn {
minimumWidth: units.gu(30)
maximumWidth: units.gu(60)
preferredWidth: units.gu(40)
}
// column #1
PageColumn {
fillWidth: true
}
}
]
Page {
id: page1
header: PageHeader {
id: header
title: "Main Page"
}
Column {
anchors.top: header.bottom
width: parent.width
ListItem {
ListItemLayout {
title.text: "Home"
}
onClicked: {
page1.pageStack.addPageToNextColumn(page1, page2)
apl.thirdCol = false
}
}
ListItem {
ListItemLayout {
title.text: "Settings"
}
onClicked: {
page1.pageStack.addPageToNextColumn(page1, page3)
apl.thirdCol = true
}
}
ListItem {
ListItemLayout {
title.text: apl.columns
}
}
}
}
Page {
id: page2
header: PageHeader {
title: "Home"
}
Rectangle {
width: Math.min(parent.width / 2, parent.height / 2)
height: width
color: "green"
anchors.centerIn: parent
}
}
Page {
id: page3
header: PageHeader {
title: "Settings"
}
Column {
anchors.top: parent.top
anchors.topMargin: header.height
width: parent.width
ListItem {
ListItemLayout {
title.text: "About"
}
onClicked: page3.pageStack.addPageToNextColumn(page3, page4)
}
}
}
Page {
id: page4
header: PageHeader {
title: "Page #4"
}
Rectangle {
width: Math.min(parent.width / 2, parent.height / 2)
height: width
color: "red"
anchors.centerIn: parent
}
}
}
}
