Access item inside ListView via delegate

[J.Hilk]

hi @Ratzz

you already "listen" to the listModel count property for your onClicked why don't you make the visible property depending on it as well ?

                  Column {
                        width: 100
                        Button {
                            text: "Delete"
                            visible: listModel.count > 1
                            onClicked:{
                                if(listModel.count > 1)
                                    listModel.remove(index);
                            }
                        }
                    }

I was able to access the TextEdit value using property value which is set to model via ListElement something like this

@J-Hilk , Is there any better way than this ?

[J.Hilk]

@Ratzz
for example, you could just bind the text directly:

                    Column {
                        width: 50
                        TextEdit { text: editableText}
                    }
...
...
     ListModel {
            id: listModel
            ListElement {
                    editableText: "SomeText"
            }
     }

That works as well

Now when I tried with empty text

ListModel {
            id: listModel
            ListElement {
                    editableText: ""
            }
     }

and then I tried to change the text field value manually say "sometext" . Button event returned null

onClicked: { 
listModel.get(0).editableText 
console.log(listModel.get(0).editableText ) //Null
}

while button event setting property gave proper result

onClicked: { 
listModel.setProperty(index, "editableText ", id.text)
console.log(listModel.get(0).editableText ) //"sometext"
}

@Ratzz interesting

I usually have c++ based models, so my experience with QML models is limited 😕

Maybe someone else know more about this behavior

@J-Hilk
okay Fine.

@Ratzz said in Access item inside ListView via delegate:

listModel.get(0).editableText

What is that line supposed to do? You are not modifying anything here

onClicked: { 
    listModel.setProperty(index, "editableText ", textEdit.text)
}

just do that instead:

onClicked: editableText = textEdit.text

[Ratzz]

@GrecKo , Yes I can do that as well.

How can I get the updated text "editableText" as soon I change the value of TextEdit is changed?

[GrecKo]

@Ratzz console.log(editableText ), you have access to the role values (as context properties) corresponding to the model cell in the delegate

[Ratzz]

@GrecKo , I mean without the button, when I edit the values of TextEdit, I should be able to get the modified text. I tried via property. It always gave me empty
