[Solved] Listview and Mousearea and setting current index

patrikd

hi all,
i have a listview and i also have a navigation which allows directly to set a current index on the listview.
clicking on the nav makes the listview scrolling to the pos of the selected item. this works so far so good.
i now added a mousearea on the listview for listening for doubleclicks, resizing the view to fullscreen.
when i use this doubleclickarea the autoscrolling to the currentindex from navigation doesn't work anymore.
i have to scroll the listview one time by hand and then the autoscrolling works again.
here my listview:
@
ListView {
id: listViewMain

                delegate: mainViewDelegate
                model: pages.pages
                snapMode: ListView.SnapOneItem;
                highlightFollowsCurrentItem: true
                highlightRangeMode:ListView.StrictlyEnforceRange
                highlightMoveDuration: 1200
                orientation: Qt.Horizontal
                clip: true
                currentIndex: 0
                onCurrentIndexChanged: {
                    console.log("currentIndex changed")
                }
                MouseArea {
                    id: doubleClickArea
                    anchors.fill: parent
                    onDoubleClicked: {
                        console.log("doubleclick")
                        if (contentPage.state == "fullscreen")
                            contentPage.state = "regular"
                        else
                            contentPage.state = "fullscreen"
                    }
                }
                

            }//end listViewMain

@

from the navigation i use:
@
listViewMain.currentIndex = targetIndex
@

"onCurrentIndexChanged" is called but the listview doesn't move anymore.
any ideas?
thx,

Hi,

What is navigation ? Is it a Component ?

patrikd

Hi p3c0,
yes its a component within a repeater. i also have two buttons within the listview at the right and left for next end prev. behaviour is the same.
best,
patrik

Trying to understand the senario:
So is it that after you double click, the screen resizes to fullscreen, then when you navigate, it doesnot scroll but the currentIndex changes ?
May be you should post a small complete working example which will explain it.

patrikd

hi p3c,
yes thats the correct scenario. and after that, when i scroll by hand once the functionallity for autoscrolling is back.
thx,

Ok. I tried something similar but it works for me. Which Qt Version and OS are you using ?
Or can you post a reduced complete compilable code which will show the problem ?

patrikd

hi,
os win8.1. behaviour is identic for android. i will try to extract the code and post it.
thx,

Qt 5.4 and 5.3

Hi p3C0,
i found the reason. at the begining of the resize transistion i called a function to lock the listview with "listview.enabled = false". a script with "enable.listview = true" was called at the end. the listview was correctly enabled but this seemed the reason for stopping of the autoscrolling.
thx for your help,
patrik

Glad to hear that it's working now. Happy coding :)
