Community extensions to the cross platform GUI in Go based on Material Design

About

This repository holds community extensions for the Fyne toolkit.

This is in early development and more information will appear soon.

Layouts

Community contributed layouts.

import "fyne.io/x/fyne/layout"

Widgets

Community contributed widgets.

import "fyne.io/x/fyne/widget"

Animated Gif

A widget that will run animated gifs.

gif, err := NewAnimatedGif(storage.NewFileURI("./testdata/gif/earth.gif"))
gif.Start()

FileTree

An extension of widget.Tree for displaying a file system hierarchy.

tree := widget.NewFileTree(storage.NewFileURI("~")) // Start from home directory
tree.Filter = storage.NewExtensionFileFilter([]string{".txt"}) // Filter files
tree.Sorter = func(u1, u2 fyne.URI) bool {
    return u1.String() < u2.String() // Sort alphabetically
}

CompletionEntry

An extension of widget.Entry for displaying a popup menu for completion. The "up" and "down" keys on the keyboard are used to navigate through the menu, the "Enter" key is used to confirm the selection. The options can also be selected with the mouse. The "Escape" key closes the selection list.

entry := widget.NewCompletionEntry([]string{})

// When the use typed text, complete the list.
entry.OnChanged = func(s string) {
    // completion start for text length >= 3
    if len(s) < 3 {
        entry.HideCompletion()
        return
    }

    // Make a search on wikipedia
    resp, err := http.Get(
        "https://en.wikipedia.org/w/api.php?action=opensearch&search=" + entry.Text,
    )
    if err != nil {
        entry.HideCompletion()
        return
    }

    // Get the list of possible completion
    var results [][]string
    json.NewDecoder(resp.Body).Decode(&results)

    // no results
    if len(results) == 0 {
        entry.HideCompletion()
        return
    }

    // then show them
    entry.SetOptions(results[1])
    entry.ShowCompletion()
}

7-Segment ("Hex") Display

A skeuomorphic widget simulating a 7-segment "hex" display. Supports setting digits by value, as well as directly controlling which segments are on or off.

Check out the demo for an example of usage.

h := widget.NewHexWidget()
// show the value 'F' on the display
h.Set(0xf)

Validation

Community contributed validators.

import fyne.io/x/fyne/data/validation

Password

A validator for validating passwords. Uses https://github.com/wagslane/go-password-validator for validation using an entropy system.

pw := validation.NewPassword(70) // Minimum password entropy allowed defined as 70.
