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 } } } } ** Affects: ubuntu-ui-toolkit (Ubuntu) Importance: Undecided Status: New ** Attachment added: "apl-2016-08-24_22.50.02.mkv" https://bugs.launchpad.net/bugs/1616798/+attachment/4727418/+files/apl-2016-08-24_22.50.02.mkv -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to ubuntu-ui-toolkit in Ubuntu. https://bugs.launchpad.net/bugs/1616798 Title: AdaptivePageLayout behaves odd, when using 3 columns Status in ubuntu-ui-toolkit package in Ubuntu: New Bug description: 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.
