Pietro Gagliardi a7ec908ebd Removed gListboxSelected; it was never being called anyway (only gListboxSelectedMulti is; Windows still uses selectedIndex() for Listbox because of differences in how multi-selection listboxes are handled there and Mac OS X never had this function written to begin with). 2014-03-09 11:36:44 -04:00
test Added bounds checks for Listbox.InsertBefore(). This stupid 32-bit Mac bug keeps Listbox.Delete() unchecked for now... 2014-03-09 10:51:01 -04:00
unmigrated Re-added Windows font grabbing code. I won't use it just yet, since I only now realize I don't actually need it for preferred sizes, but eh 2014-02-24 11:55:38 -05:00
.travis.yml Remove the 32-bit GTK+ from linux/386 Travis.ci builds; I have no idea how to fix this. 2014-03-05 12:38:49 -05:00

bleh_darwin.m Have ui.Go() return on main() return on Mac OS X. 2014-03-05 20:09:15 -05:00
button.go Fixed Mac OS X control placement flipping. This is done by passing the height of the window around setRect() calls to avoid polling the content view frame each time. 2014-03-03 17:44:03 -05:00
callbacks_unix.go Moved to a proper package; main() is now a test and go test -c is used to build. Once I iron out a bug with Windows event handling, I'll add a README. 2014-02-19 11:41:10 -05:00

restrictions.md Windows sysData has been adjusted to deal with child controls. Rather than storing the parent window, it is passed as an argument to sysData.make(), which does the child ID allocation. Child IDs are now window-local, getting rid of that restriction. 2014-02-12 21:08:10 -05:00

Build Status

Native UI library for Go

THIS PACKAGE IS UNDER ACTIVE DEVELOPMENT. Feel free to start using it, but mind: it's far from feature-complete, it's still in need of testing and crash-fixing, and the API can (and will) change. If you can help, please do! Run ./test to build a test binary test/test which runs a (mostly) feature-complete UI test. Run ./d32 ./test to build a 32-bit version (you will need a cgo-enabled 32-bit go environment, and I have only tested this on Mac OS X).

This is a simple library for building cross-platform GUI programs in Go. It targets Windows, Mac OS X, Linux, and other Unixes, and provides a thread-safe, channel-based API. The API itself is minimal; it aims to provide only what is necessary for GUI program design. That being said, suggestions are welcome. Layout is done using various layout managers, and some effort is taken to conform to the target platform's UI guidelines. Otherwise, the library uses native toolkits.

ui aims to run on all supported versions of supported platforms. To be more precise, the system requirements are:

  • Windows: Windows 2000 or newer. The Windows backend uses package syscall and calls Windows DLLs directly, so does not rely on cgo.
  • Mac OS X: Mac OS X 10.6 (Snow Leopard) or newer. Objective-C dispatch is done by interfacing with libobjc directly, and thus this uses cgo.
    • Note: you will need Go 1.3 or newer for this verison, as it uses a single .m file due to technical restrictions (read the comments in bleh_darwin.m for details), and earlier versions of Go do not auto-build .m files.
  • Other Unixes: The Unix backend uses GTK+, and thus cgo. It requires GTK+ 3.4 or newer; for Ubuntu this means 12.04 LTS (Precise Pangolin) at minimum. Check your distribution.

ui itself has no outside Go package dependencies; it is entirely self-contained.

To install, simply go get this package. On Mac OS X, make sure you have the Apple development headers. On other Unixes, make sure you have the GTK+ development files (for Ubuntu, libgtk-3-dev is sufficient).

Package documentation is available at http://godoc.org/github.com/andlabs/ui.

For an example of how ui is used, see https://github.com/andlabs/wakeup, which is a small program that implements a basic alarm clock.

Contributing

Contributions are welcome. File issues, pull requests, approach me on IRC (pietro10 in #go-nuts; andlabs elsewhere), etc. Even suggestions are welcome: while I'm mainly drawing from my own GUI programming experience, everyone is different.

If you want to dive in, read implementation.md: this is a description of how the library works. (Feel free to suggest improvements to this as well.) The other .md files in this repository contain various development notes.

Please suggest documentation improvements as well.
