开源软件名称(OpenSource Name):fyne-io/fyne开源软件地址(OpenSource Url):https://github.com/fyne-io/fyne开源编程语言(OpenSource Language):Go 95.4%开源软件介绍(OpenSource Introduction):AboutFyne is an easy-to-use UI toolkit and app API written in Go. It is designed to build applications that run on desktop and mobile devices with a single codebase. Version 2.2 is the current release of the Fyne API, it added system tray support,
PrerequisitesTo develop apps using Fyne you will need Go version 1.14 or later, a C compiler and your system's development tools. If you're not sure if that's all installed or you don't know how then check out our Getting Started document. Using the standard go tools you can install Fyne's core library using:
Widget demoTo run a showcase of the features of Fyne execute the following:
And you should see something like this (after you click a few buttons): Or if you are using the light theme: And even running on a mobile device: Getting StartedFyne is designed to be really easy to code with. If you have followed the prerequisite steps above then all you need is a Go IDE (or a text editor). Open a new file and you're ready to write your first app! package main
import (
"fyne.io/fyne/v2/app"
"fyne.io/fyne/v2/container"
"fyne.io/fyne/v2/widget"
)
func main() {
a := app.New()
w := a.NewWindow("Hello")
hello := widget.NewLabel("Hello Fyne!")
w.SetContent(container.NewVBox(
hello,
widget.NewButton("Hi!", func() {
hello.SetText("Welcome :)")
}),
))
w.ShowAndRun()
} And you can run that simply as:
It should look like this:
Run in mobile simulationThere is a helpful mobile simulation mode that gives a hint of how your app would work on a mobile device:
Another option is to use InstallingUsing
Packaging for mobileTo run on a mobile device it is necessary to package up the application. To do this we can use the fyne utility "package" subcommand. You will need to add appropriate parameters as prompted, but the basic command is shown below. Once packaged you can install using the platform development tools or the fyne "install" subcommand.
The built Android application can run either in a real device or an Android emulator. However, building for iOS is slightly different. If the "-os" argument is "ios", it is build only for a real iOS device. Specify "-os" to "iossimulator" allows the application be able to run in an iOS simulator:
Preparing a releaseUsing the fyne utility "release" subcommand you can package up your app for release
to app stores and market places. Make sure you have the standard build tools installed
and have followed the platform documentation for setting up accounts and signing.
Then you can execute something like the following, notice the
The above command will create a '.ipa' file that can then be uploaded to the iOS App Store. DocumentationMore documentation is available at the Fyne developer website or on pkg.go.dev. ExamplesYou can find many example applications in the examples repository. Alternatively a list of applications using fyne can be found at our website. Shipping the Fyne ToolkitAll Fyne apps will work without pre-installed libraries, this is one reason the apps are so portable. However, if looking to support Fyne in a bigger way on your operating system then you can install some utilities that help to make a more complete experience. Additional appsIt is recommended that you install the following additional apps:
These are optional applications but can help to create a more complete desktop experience. FyneDesk (Linux / BSD)To go all the way with Fyne on your desktop / laptop computer you could install FyneDesk as well :) |
