Keyed list

A keyed list is a widget that allows you to display a map value to users and have them edit it (core.KeyedList). Users can use context menus to add, remove, and move rows.

For a slice, use a list instead. For a slice of structs, use a table. For a single struct, use a form. For a nested tree, use a tree.

Properties

You can make a keyed list from any map pointer:

core.NewKeyedList(b).SetMap(&map[string]int{"Go": 1, "C++": 3, "Python": 5})

You can make a keyed list that fits in one line:

core.NewKeyedList(b).SetInline(true).SetMap(&map[string]int{"Go": 1, "C++": 3})

You can prevent users from editing a keyed list:

core.NewKeyedList(b).SetMap(&map[string]int{"Go": 1, "C++": 3, "Python": 5}).SetReadOnly(true)

You can make a keyed list with elements of any type:

core.NewKeyedList(b).SetMap(&map[string]any{"Go": 1, "C++": "C-like", "Python": true})

Events

You can detect when a user changes the value of a keyed list:

m := map[string]int{"Go": 1, "C++": 3, "Python": 5}
core.NewKeyedList(b).SetMap(&m).OnChange(func(e events.Event) {
    core.MessageSnackbar(b, fmt.Sprintf("Map: %v", m))
})

Keyed list button

You can make a button that opens a dialog with a keyed list:

core.NewKeyedListButton(b).SetMap(&map[string]int{"Go": 1, "C++": 3, "Python": 5})
