If I add an ActionSet to a StandardListItem, then how do I find out which row (or indexPath) triggered an action?

[lew]

use the onTriggered event of the listview:

ListView {
 ...
 dataModel: ...

 listItemComponents: ...

 onTriggered: {
   var chosenItem = dataModel.data(indexPath);
   //do w/e here
 }

}

Also please check the docs, it's properly explained over there:

This is the way you handle list item selection. But how to do this for an ActionItem? As far as I know, there is no such thing as a global indexPath for this (in C).

ooops my bad

this one is a little bit more complicated, and the documentation is indeed lacking on that part, here goes:

1) make sure your row data have some sort of unique identifier (id in this case)

2) add a function to handle your context action menu at the same level as your ListView (see doSomethingWithContextAction below)

3) from your ListItemComponent, access your listView, then call the function in step (2) by passing as argument your unique id

ListView {
 ...
 dataModel: ...

 listItemComponents: [
   ListItemComponent {
     Container {
         id: listItemComponentContainer //this is required!
         ...ActionItem {
             onTriggered: {
listItemComponentContainer.ListItem.view.doSomethingForContextAction(ListItemData.id)

             }
         }
     }
   }
 ]

 onTriggered: {
   var chosenItem = dataModel.data(indexPath);
   //do w/e here
 }

 function doSomethingForContextAction(someId){
 }

}

Thanks, it looks clear.

How would this work in C, though?

i'll let you figure that one  

given how awful the QDE is, i tried to avoid as much c++ as possible...

[marcelnijman]

hehehe.

qde is not the best, but I have all my code in c++, so converting to qml is not optimal.
