Icon

Package gi is the top-level repository for the GoGi GUI framework. All of the code is in the sub-packages within this repository: * gist: css-based styling settings, including Color * girl: rendering library, can be used standalone, SVG compliant * gi: the main 2D GUI Node, Widgets, and RenderWin * giv: more complex Views of Go data structures, supporting Model-View paradigm. * svg: full SVG rendering framework, used for Icons in gi. * gi3d: 3D rendering of a Scene within 2D windows -- full interactive 3D scenegraph. * histyle: text syntax-based highlighting styles -- used in textview.View * python: access all of GoGi from within Python using GoPy system.

Package systray is a cross-platform Go library to place an icon and menu in the notification area.

Package trayhost is a cross-platform Go library to place an icon in the host operating system's taskbar. - macOS - Fully implemented and supported by @dmitshur. - Linux - Partially implemented, but unsupported (needs an owner/maintainer). - Windows - Partially implemented, but unsupported (needs an owner/maintainer). On macOS, for Notification Center user notifications to work, your Go binary that uses trayhost must be a part of a standard macOS app bundle. Most other functionality of trayhost will be available if the binary is not a part of app bundle, but you will get a terminal pop up, and you will not be able to configure some aspects of the app. Here's a minimal layout of an app bundle: Here's a minimal Info.plist file as reference (only the entries that are needed, nothing extra): - CFBundleIdentifier needs to be set to some value for Notification Center to work. - The binary must be inside Contents/MacOS directory for Notification Center to work. - NSHighResolutionCapable to enable Retina mode. - LSUIElement is needed to make the app not appear in Cmd+Tab list and the dock while still being able to show a tooltip in the menu bar. On macOS, when you run an app bundle, the working directory of the executed process is the root directory (/), not the app bundle's Contents/Resources directory. Change directory to Resources if you need to load resources from there.

Package trayhost is a library for placing a Go application in the task bar (system tray, notification area, or dock) in a consistent manner across multiple platforms. Currently, there is built-in support for Windows, Mac OSX, and Linux systems that support GTK+ 3 status icons (including Gnome 2, KDE 4, Cinnamon, MATE and other desktop environments). The indended usage is for applications that utilize web technology for the user interface, but require access to the client system beyond what is offered in a browser sandbox (for instance, an application that requires access to the user's file system). The library places a tray icon on the host system's task bar that can be used to open a URL, giving users easy access to the web-based user interface.

Package icns implements an encoder for Apple's `.icns` file format. Reference: "https://en.wikipedia.org/wiki/Apple_Icon_Image_format". icns files allow for high resolution icons to make your apps look sexy. The most common ways to generate icns files are 1. use `iconutil` which is a Mac native cli utility, or 2. use tools that wrap `ImageMagick` which adds a large dependency to your project for such a simple use case. With this library you can use pure Go to create icns files from any source image, given that you can decode it into an `image.Image`, without any heavyweight dependencies or subprocessing required. You can also use this library to create icns files on windows and linux. A small CLI app `icnsify` is provided to allow you to create icns files using this library from the command line. It supports piping, which is something `iconutil` does not do, making it substantially easier to wrap. Note: All icons within the icns are sized for high dpi retina screens, using the appropriate icns OSTypes.
