How to set and retrieve a class object in a ListView?

[gloomy summit]

Hi,
I'm coding a project that has a class that is called Course, and I wanted to implement a way for a user in my application to search for courses. To do this, I've set up the retrieval from a database for courses. However, I'm currently stuck in figuring out how to display my objects into a ListView and then retrieving the object once a user selects one and clicks a button.

From what I've googled online, theres only solutions for displaying an object inside a list which doesn't solve the latter of my problem, and utilising an ArrayAdaptor to convert the objects into something recognisable for a list. However, the second solution I couldn't figure out how to extend the ArrayAdapter, and all the online guides seemed to be tailored for Android development rather than just a desktop application.

So, are there any simpler solutions to setting and retrieving a class object in a listview? And if the ArrayAdapter is my only solution, could someone help explain how it works, as I'm currently lost with the guides.

Hi, what exactly is your issue? Can you post some code of what have you tried?

Are you sure you are talking about JavaFX? AFAIK there is not ListAdapter necessary for listView...

[gloomy summit]

Yes I am talking about JavaFX
So far I haven't tried any code as I was confused about how to approach the issue

and the issue is I want to load an array of custom objects

into a list

and let a user select an option

and then retrieve the object from that selection

but im not sure how to go about doing that

[gloomy summit]

so if I can populate a listview like that

can I simply just retrieve the object from the same list?

[stiff parrot]

sure

there is a "selectionModel" method on the ListView instance where you can add a listener to selectionChange

Also this "selectionModel" have a property of "selectedItem"

[gloomy summit]

so something like listview.getselectionmodel.getSelectedItem()
should net me back my object?

[stiff parrot]

yes

[gloomy summit]

hm

ok, now its clearer

thanks mate
