systray is a cross-platform Go library to place an icon and menu in the notification area.
## Features
* Supported on Windows, macOS, and Linux
* Menu items can be checked and/or disabled
* Methods may be called from any Goroutine
## API
```go
func main() {
systray.Run(onReady, onExit)
}
func onReady() {
systray.SetIcon(icon.Data)
systray.SetTitle("Awesome App")
systray.SetTooltip("Pretty awesome超级棒")
mQuit := systray.AddMenuItem("Quit", "Quit the whole app")
// Sets the icon of a menu item. Only available on Mac and Windows.
mQuit.SetIcon(icon.Data)
}
func onExit() {
// clean up here
}
```
See [full API](https://pkg.go.dev/github.com/getlantern/systray?tab=doc) as well as [CHANGELOG](https://github.com/getlantern/systray/tree/master/CHANGELOG.md).
## Try the example app!
Have go v1.12+ or higher installed? Here's an example to get started on macOS:
```sh
git clone https://github.com/getlantern/systray
cd example
env GO111MODULE=on go build
./example
```
On Windows, you should build like this:
```
env GO111MODULE=on go build -ldflags "-H=windowsgui"
```
The following text will then appear on the console:
```sh
go: finding github.com/skratchdot/open-golang latest
go: finding github.com/getlantern/systray latest
go: finding github.com/getlantern/golog latest
```
Now look for *Awesome App* in your menu bar!
![Awesome App screenshot](example/screenshot.png)
## The Webview example
The code under `webview_example` is to demostrate how it can co-exist with other UI elements. Note that the example doesn't work on macOS versions older than 10.15 Catalina.
## Platform notes
### Linux
* Building apps requires gcc as well as the `gtk3` and `libappindicator3` development headers to be installed. For Debian or Ubuntu, you may install these using:
```sh
sudo apt-get install gcc libgtk-3-dev libappindicator3-dev
```
On Linux Mint, `libxapp-dev` is also required .
To build `webview_example`, you also need to install `libwebkit2gtk-4.0-dev` and remove `webview_example/rsrc.syso` which is required on Windows.
### Windows
* To avoid opening a console at application startup, use these compile flags:
```sh
go build -ldflags -H=windowsgui
```
### macOS
On macOS, you will need to create an application bundle to wrap the binary; simply folders with the following minimal structure and assets:
```
SystrayApp.app/
Contents/
Info.plist
MacOS/
go-executable
Resources/
SystrayApp.icns
```
When running as an app bundle, you may want to add one or both of the following to your Info.plist:
```xml
<!-- avoid having a blurry icon and text -->
<key>NSHighResolutionCapable</key>
<string>True</string>
<!-- avoid showing the app on the Dock -->
<key>LSUIElement</key>
<string>1</string>
```
Consult the [Official Apple Documentation here](https://developer.apple.com/library/archive/documentation/CoreFoundation/Conceptual/CFBundles/BundleTypes/BundleTypes.html#//apple_ref/doc/uid/10000123i-CH101-SW1).

# Systray
systray is a cross-platform Go library to place an icon and menu in the notification area.
This repository is a fork of [getlantern/systray](https://github.com/getlantern/systray)
removing the GTK dependency and support for legacy linux system tray.
## Features
* Supported on Windows, macOS, Linux and many BSD systems
* Menu items can be checked and/or disabled
* Methods may be called from any Goroutine
## API
```go

### Running in a Fyne app
This repository is designed to allow any toolkit to integrate system tray without any additional dependencies.
It is maintained by the Fyne team, but if you are using Fyne there is an even easier to use API in the main repository that wraps this project.
In your app you can use a standard `fyne.Menu` structure and pass it to `SetSystemTrayMenu` when your app is a desktop app, as follows:
```go
menu := fyne.NewMenu("MyApp",
fyne.NewMenuItem("Show", func() {
log.Println("Tapped show")
}))
if desk, ok := myApp.(desktop.App); ok {
desk.SetSystemTrayMenu(menu)
}
```
You can find out more in the toolkit documentation:
[System Tray Menu](https://developer.fyne.io/explore/systray).
### Run in another toolkit
Most graphical toolkits will grab the main loop so the `Run` code above is not possible.
For this reason there is another entry point `RunWithExternalLoop`.
This function of the library returns a start and end function that should be called
when the application has started and will end, to loop in appropriate features.
See [full API](https://pkg.go.dev/fyne.io/systray?tab=doc) as well as [CHANGELOG](https://github.com/fyne-io/systray/tree/master/CHANGELOG.md).
Note: this package requires cgo, so make sure you set `CGO_ENABLED=1` before building.
## Try the example app!
Have go v1.12+ or higher installed? Here's an example to get started on macOS or Linux:
```sh
git clone https://github.com/fyne-io/systray
cd systray/example
go run .
```
On Windows, you should follow the instructions above, but use the followign run command:
```
go run -ldflags "-H=windowsgui" .
```
Now look for *Awesome App* in your menu bar!
![Awesome App screenshot](example/screenshot.png)
## Platform notes
### Linux/BSD
This implementation uses DBus to communicate through the SystemNotifier/AppIndicator spec, older tray implementations may not load the icon.
If you are running an older desktop environment, or system tray provider, you may require a proxy app which can convert the new DBus calls to the old format.
The recommended tool for Gnome based trays is [snixembed](https://git.sr.ht/~steef/snixembed), others are available.
Search for "StatusNotifierItems XEmbedded" in your package manager.
### Windows
* To avoid opening a console at application startup, use "fyne package" for your app or manually use these compile flags:
```sh
go build -ldflags -H=windowsgui
```
### macOS
On macOS, you will need to create an application bundle to wrap the binary; simply use "fyne package" or add folders with the following minimal structure and assets:
```
SystrayApp.app/
Contents/
Info.plist
MacOS/
go-executable
Resources/
SystrayApp.icns
```
If bundling manually, you may want to add one or both of the following to your Info.plist:
```xml
<!-- avoid having a blurry icon and text -->
<key>NSHighResolutionCapable</key>
<string>True</string>
<!-- avoid showing the app on the Dock -->
<key>LSUIElement</key>
<string>1</string>
```
Consult the [Official Apple Documentation here](https://developer.apple.com/library/archive/documentation/CoreFoundation/Conceptual/CFBundles/BundleTypes/BundleTypes.html#//apple_ref/doc/uid/10000123i-CH101-SW1).
On macOS, it's possible to set the underlying
[`NSStatusItemBehavior`](https://developer.apple.com/documentation/appkit/nsstatusitembehavior?language=objc)
with `systray.SetRemovalAllowed(true)`. When enabled, the user can cmd-drag the
icon off the menu bar.

# How to Contribute
## Getting Started
- Fork the repository on GitHub
- Read the [README](README.markdown) for build and test instructions
- Play with the project, submit bugs, submit patches!
## Contribution Flow
This is a rough outline of what a contributor's workflow looks like:
- Create a topic branch from where you want to base your work (usually master).
- Make commits of logical units.
- Make sure your commit messages are in the proper format (see below).
- Push your changes to a topic branch in your fork of the repository.
- Make sure the tests pass, and add any new tests as appropriate.
- Submit a pull request to the original repository.
Thanks for your contributions!
### Format of the Commit Message
We follow a rough convention for commit messages that is designed to answer two
questions: what changed and why. The subject line should feature the what and
the body of the commit should describe the why.
```
scripts: add the test-cluster command
this uses tmux to setup a test cluster that you can easily kill and
start for debugging.
Fixes #38
```
The format can be described more formally as follows:
```
<subsystem>: <what changed>
<BLANK LINE>
<why this change was made>
<BLANK LINE>
<footer>
```
The first line is the subject and should be no longer than 70 characters, the
second line is always blank, and other lines should be wrapped at 80 characters.
This allows the message to be easier to read on GitHub as well as in various
git tools.

![Build Status](https://github.com/godbus/dbus/workflows/Go/badge.svg)
dbus
----
dbus is a simple library that implements native Go client bindings for the
D-Bus message bus system.
### Features
* Complete native implementation of the D-Bus message protocol
* Go-like API (channels for signals / asynchronous method calls, Goroutine-safe connections)
* Subpackages that help with the introspection / property interfaces
### Installation
This packages requires Go 1.12 or later. It can be installed by running the command below:
```
go get github.com/godbus/dbus/v5
```
### Usage
The complete package documentation and some simple examples are available at
[godoc.org](http://godoc.org/github.com/godbus/dbus). Also, the
[_examples](https://github.com/godbus/dbus/tree/master/_examples) directory
gives a short overview over the basic usage.
#### Projects using godbus
- [fyne](https://github.com/fyne-io/fyne) a cross platform GUI in Go inspired by Material Design.
- [fynedesk](https://github.com/fyne-io/fynedesk) a full desktop environment for Linux/Unix using Fyne.
- [go-bluetooth](https://github.com/muka/go-bluetooth) provides a bluetooth client over bluez dbus API.
- [iwd](https://github.com/shibumi/iwd) go bindings for the internet wireless daemon "iwd".
- [notify](https://github.com/esiqveland/notify) provides desktop notifications over dbus into a library.
- [playerbm](https://github.com/altdesktop/playerbm) a bookmark utility for media players.
Please note that the API is considered unstable for now and may change without
further notice.
### License
go.dbus is available under the Simplified BSD License; see LICENSE for the full

/*
Package dbus implements bindings to the D-Bus message bus system.
To use the message bus API, you first need to connect to a bus (usually the
session or system bus). The acquired connection then can be used to call methods
on remote objects and emit or receive signals. Using the Export method, you can
arrange D-Bus methods calls to be directly translated to method calls on a Go
value.
Conversion Rules
For outgoing messages, Go types are automatically converted to the
corresponding D-Bus types. See the official specification at
https://dbus.freedesktop.org/doc/dbus-specification.html#type-system for more
information on the D-Bus type system. The following types are directly encoded
as their respective D-Bus equivalents:
Go type | D-Bus type
------------+-----------
byte | BYTE
bool | BOOLEAN
int16 | INT16
uint16 | UINT16
int | INT32
uint | UINT32
int32 | INT32
uint32 | UINT32
int64 | INT64
uint64 | UINT64
float64 | DOUBLE
string | STRING
ObjectPath | OBJECT_PATH
Signature | SIGNATURE
Variant | VARIANT
interface{} | VARIANT
UnixFDIndex | UNIX_FD
Slices and arrays encode as ARRAYs of their element type.
Maps encode as DICTs, provided that their key type can be used as a key for
a DICT.
Structs other than Variant and Signature encode as a STRUCT containing their
exported fields in order. Fields whose tags contain `dbus:"-"` and unexported
fields will be skipped.
Pointers encode as the value they're pointed to.
Types convertible to one of the base types above will be mapped as the
base type.
Trying to encode any other type or a slice, map or struct containing an
unsupported type will result in an InvalidTypeError.
For incoming messages, the inverse of these rules are used, with the exception
of STRUCTs. Incoming STRUCTS are represented as a slice of empty interfaces
containing the struct fields in the correct order. The Store function can be
used to convert such values to Go structs.
Unix FD passing
Handling Unix file descriptors deserves special mention. To use them, you should
first check that they are supported on a connection by calling SupportsUnixFDs.
If it returns true, all method of Connection will translate messages containing
UnixFD's to messages that are accompanied by the given file descriptors with the
UnixFD values being substituted by the correct indices. Similarly, the indices
of incoming messages are automatically resolved. It shouldn't be necessary to use
UnixFDIndex.
