changing state of previously selected list item

[tyrnikeisari]

Hi

I have a QML application with ListView and ListModel. When I click an list item I'll change it's state (to "selected") and draw it bit differently. This works just fine.

Next I'll select another item from the list. At this point I would like to change previously selected items state back to "unselected". I know the index of the item, but I can't figure out how to access delegate's state.

How I can do this or is there better approach? I'm just testing and learning how to do things before actually implementing my application.

Hi tyrnikeisari,

You can try to access the attached property "view" of the QML ListView element from your delegate ListView.view.

So in your delegate, when drawing the "selected" item you can use a condition like:

if (ListView.view.currentIndex == index)

if (ListView.view.currentIndex == index)

To copy to clipboard, switch view to plain text mode 

Hope this is useful.

Hi Wladek

Thanks for your reply.

I added the check when focus changes and that did the trick. I have in my delegate item:

onFocusChanged: {
    if(listView.currentIndex == index){
         delegateItem.state = 'selected';
    }
    else{
          delegateItem.state = 'deselected';
    }
}

onFocusChanged: {
    if(listView.currentIndex == index){
         delegateItem.state = 'selected';
    }
    else{
          delegateItem.state = 'deselected';
    }
}

To copy to clipboard, switch view to plain text mode
