SelectEntry

The select entry widget combines the Entry and the select widget described in Choices. The user can pick one of the values you offer from a drop-down list, or they can ignore the list and type a value of their own.

Construct one with widget.NewSelectEntry(), passing a slice of string for the options that should be suggested. The list can be replaced later using SetOptions(...).

Because a select entry extends the entry widget you use it in the same way - read the Text field for the current value and set OnChanged to be told when it changes, whether the user typed the text or chose it from the list. Fields like PlaceHolder and Validator work as they do for a regular entry.

  package main

import (
	"log"

	"fyne.io/fyne/v2"
	"fyne.io/fyne/v2/app"
	"fyne.io/fyne/v2/widget"
)

func main() {
	myApp := app.New()
	myWindow := myApp.NewWindow("SelectEntry Widget")

	combo := widget.NewSelectEntry([]string{"Red", "Green", "Blue"})
	combo.PlaceHolder = "Choose or type a colour"
	combo.OnChanged = func(value string) {
		log.Println("Colour is", value)
	}

	myWindow.SetContent(combo)
	myWindow.Resize(fyne.NewSize(250, 100))
	myWindow.ShowAndRun()
}
