Looking for a robust listbox replacement for the one I wrote ages ago

[DecapitatedKneecap]

About 10 years ago, I started writing my own console listbox control in C#. It worked great with Windows 7's conhost, but it's not playing too well with Window 11's new terminal due to how I rely on Console.WindowWidth and other dimensional properties to dynamically size the list control. I am looking for a replacement, but can't find any that support all of the same features as mine. Here are some of the features off the top of my head:

• Add items (+)
• Delete items (del)
• Disable items
• Single/multiselect
• Cancel selection/close listbox (esc)
• Swap items (ctrl+shift+up/down)
• Select all (ctrl+a)
• Deselect all (ctrl+d)
• Invert selection (ctrk+shift+i)
• Arrowing up/down through paginated list wraps to top/bottom of current page instead of advancing through pages
• Keydown events
• Each item is ListItem<T> which contains state info that you can retrieve via listbox.GetSelectedItem()
• Remembers last-selected index/page when reusing listbox instance
• Conditional state per item (colors, disabled, etc)

Does Terminal.Gui have a list control that supports these features? If not, would it be relatively straightforward for a new contributor such as myself to implement them?

Yes indeed.

ListView in v2 is built to show an IObservableList

You could use element T being a stateful object.

From your list, I think the only thing missing is 'Disabled' items.

You would need to write event handler for keys like Delete - but just have to wire up to remove from the backing list collection.

We also have:

• CollectionNavigator which let's you cycle through a letter e.g. 'a' to jump to next item beginning with a
• Cross platform support (works on Windows, Linux and MacOS)

For color, you would need to implement draw handler for the list items. I.e. implement the RowRender event or probably better to use Source.Render depending on use case

We also have

• TreeView
• TableView

If you need child items and/or multiple columns of data

TableView can also be set up to work like a list:

I'll have a look at it then, thanks!
