Trigger function call in ListView delegate

[Bob64]

I feel as though I should know how to do this but I am struggling to know what to write in my ListView delegate.

It's essentially a TextInput that I want to call select() on, giving it arguments that are stored in my ListModel.

Assume I have selstart and selend fields in my model. There isn't an option in TextInput to bind these to properties; there is just the select() function. In other circumstances I would deal with this sort of thing with a Connection to call a function in response to a property change but that doesn't seem appropriate for a model-delegate interaction.

@J-Hilk Thanks. My problem (late last night!) with Connections was that I couldn't see how to make a connection to a model role. I resolved it by introducing an intermediate property in the component and binding the model role to that. I don't know if there is a better or more direct way but that seems to work.

     ...
     property var start: selstart  // selstart is a model role

     onStartChanged: doSomething()
     ...

@Bob64
If I understand you correctly, than I would personally go with either a Connection inside the delegate - like you suggested - or via a Binding
