FormLayout布局和FormItem对比

FormLayout布局

package main

import (
	"fyne.io/fyne/v2"
	"fyne.io/fyne/v2/app"
	"fyne.io/fyne/v2/container"
	"fyne.io/fyne/v2/layout"
	"fyne.io/fyne/v2/widget"
)


func main() {
	myApp := app.New()
	myWindow := myApp.NewWindow("VPN")
	userLable := widget.NewLabel("USERNAME")
	userEntry := widget.NewEntry()

	passLable := widget.NewLabel("PASSWORD")
	passEntry := widget.NewPasswordEntry()

	c := container.New(layout.NewFormLayout(), userLable, userEntry, passLable, passEntry)
	myWindow.SetContent(c)
	myWindow.Resize(fyne.NewSize(300, 300))
	myWindow.Show()
	myApp.Run()
}

效果图如下:

FormItem

package main

import (
	"fyne.io/fyne/v2"
	"fyne.io/fyne/v2/app"
	"fyne.io/fyne/v2/container"
	"fyne.io/fyne/v2/layout"
	"fyne.io/fyne/v2/widget"
)

func main() {
	myApp := app.New()
	myWindow := myApp.NewWindow("VPN")
	userEntry := widget.NewEntry()
	userL := widget.NewFormItem("USERNAME", userEntry)
	passEntry := widget.NewPasswordEntry()
	passL := widget.NewFormItem("PASSWORD", passEntry)
	form := widget.NewForm(userL, passL)
	c := container.NewVBox(form)
	myWindow.SetContent(c)
	myWindow.Resize(fyne.NewSize(300, 300))
	myWindow.Show()
	myApp.Run()
}

效果图如下:

总结

1.这2个都能达到同样的效果。

2.角色定位：FormLayout是布局方式，负责安排对象的位置和大小；FormItem是表单项，负责收集用户输入的数据。
