File tree

A file tree is a widget that allow users to view directories as nested trees (filetree.Tree).

For displaying a list of files with metadata, consider a file picker instead.

Properties

You can make a file tree and open it at any filepath:

filetree.NewTree(b).OpenPath(".")

Events

You can detect when a user selects files:

ft := filetree.NewTree(b).OpenPath(".")
ft.OnSelect(func(e events.Event) {
    selected := []string{}
    ft.SelectedFunc(func(n *filetree.Node) {
        selected = append(selected, string(n.Filepath))
    })
    core.MessageSnackbar(ft, strings.Join(selected, " "))
})

You can filter which files or directories are shown:

ft := filetree.NewTree(b)
ft.FilterFunc = func(path string, info fs.FileInfo) bool {
    return info.IsDir() // only show directories
}
ft.OpenPath(".")
