import (
  "image/color"

  "fyne.io/fyne/v2"
  "fyne.io/fyne/v2/app"
  "fyne.io/fyne/v2/canvas"
  "fyne.io/fyne/v2/container"
)

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

  // Create a red line
  line := canvas.NewLine(color.RGBA{R: 255, G: 0, B: 0, A: 255})
  line.StrokeWidth = 4 // thickness

  // The line needs a container to give it space
  content := container.NewWithoutLayout(line)
  line.Resize(fyne.NewSize(200, 0)) // length in px
  line.Move(fyne.NewPos(20, 50))    // x, y position

  myWindow.SetContent(content)
  myWindow.Resize(fyne.NewSize(300, 150))
  myWindow.ShowAndRun()
}
