Scroll

The Scroll container shows a portion of content that is larger than the space available, adding scrollbars so the user can move around it. Wrap any fyne.CanvasObject using container.NewScroll(...) and it will be given its minimum size, with anything that does not fit being scrolled to.

If you only want movement in one direction then use container.NewVScroll(...) or container.NewHScroll(...), which scroll vertically and horizontally respectively. A vertical scroll is the usual choice for a long form or document, as the content can then grow downwards whilst still fitting the width of the window.

Note that a scroll container has a very small minimum size - it is asking to be given whatever space is going spare. That means a window should be resized, or the scroll placed in a layout that expands it, otherwise there may be nothing to see. It also means you should not put a scroll inside a Box container along the direction it scrolls, as the box will only offer the minimum size.

The current position is available in the Offset field, and ScrollToTop(), ScrollToBottom() and ScrollToOffset(...) let your code move the view. The collection widgets scroll internally, so they do not need to be wrapped in this container.

  package main

import (
	"fmt"

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

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

	content := container.NewVBox()
	for i := 1; i <= 50; i++ {
		content.Add(widget.NewLabel(fmt.Sprintf("Line %d of some long content", i)))
	}

	scroll := container.NewVScroll(content)

	myWindow.SetContent(scroll)
	myWindow.Resize(fyne.NewSize(300, 200))
	myWindow.ShowAndRun()
}
