Editable text

ui.EditableText shows a *string as a text that the user edits in place, as a file's name in Finder: a double click on it, or Enter while it has the focus, shows a text input of it, with the text before its extension selected. Enter keeps what was typed, as moving the focus away does, and Escape goes back; Changed reports a new value.

if ui.EditableText(c, &app.title).Changed() {
	app.save()
}

In lists and tables

In a list's or a table's rows, the list keeps the focus and the text takes none: Return on macOS, and F2 elsewhere, edit the text of the row chosen, while a double click on the row is Submitted; a click on the text of a row already chosen edits it, once a second click would no longer make a double click.

ui.Table(c, &app.files, cols, len(files), func(row, col int) {
	if col == 0 && ui.EditableText(c, &files[row].Name).Changed() {
		app.rename(files[row])
	}
})

Accessibility

Assistive technology reads the text, and the text field while it is edited.
