Note to ALL users: please read and comment; the design of the package is fatally flawed but I want to know what people think of the fix.

Note to Mac users: there is a bug in Go 1.3 stable that causes cgo to crash trying to build this package. Please follow the linked bug report for detials.

Woah, lots of attention! Thanks!

Updates

• 26 June 2014

  • Controls in Windows can now be spaced apart more naturally. Call w.SetSpaced(true) to opt in. Whether this will remain opt-in or whether the name will change is still unknown at this point.
  • There's a new function Layout() which provides high-level layout creation. The function was written by boppreh and details can be found here. Whether this function will stay in the main package or be moved to a subpackage is still unknown.
  • There is now Checkbox.SetChecked() to set the check state of a Checkbox programmatically.

• 25 June 2014
  Labels by default now align themselves relative to the control they are next to. There is a new function NewStandaloneLabel() which returns a label whose text is aligned to the top-left corner of the alloted space regardless.

  I have decided to remove Mac OS X 10.6 support because it's only causing problems for building (and everyone else says I should anyway, including Mac developers!). This does break my original goal, but I'm going to have to break things sooner or later. Please let me know if any of you actually use this package on 10.6. (I personally don't like it when programs require 10.7 (or iOS 7, for that matter), but what are you gonna do?)

README

This is a placeholder README; the previous file (olddocs/oldREADME.md) was rather long and confusing. I'll be rewriting it properly soon.

Until then, here's the important things you need to know:

• this package is very much incomplete; see stable.md for a list of what is guaranteed to not change at the API level — for everything newer, you have been warned!
• this package requires Go 1.3, which is presently available as a RC build (source builds from go tip will work too)
  • I don't think the Windows side uses any Go 1.3 features, but just to be safe I'm going to say express caution
  • Unix builds need 1.3 to fix some type-checker bugs in cgo
  • Mac OS X builds need 1.3 because Go 1.3 adds Objective-C support to cgo
• the Windows build does not need cgo unless you want to regenerate the zconstants_windows_*.go files; the other targets do
• my plan is to target all versions of OSs that Go itself supports. I will, however, make concessions where appropriate. This means:
  • Windows: Windows XP or newer
  • Unix: this is trickier; I decided to settle on GTK+ 3.4 or newer as Ubuntu 12.04 LTS ships with it
  • Mac OS X: Mac OS X 10.7 or newer (Go supports 10.6 but this is a pain to compile Cocoa programs for due to flaws in the later header files)
• for the Windows build, you won't need to provide a comctl32.dll version 6 manifest, as the package produces its own
  • comctl32.dll version 6 is required for proper functioning!

andlabs/wakeup is a repository that provides a sample application.

If you are feeling adventurous, running ./test.sh (which accepts go build options) from within the package directory will build a test program which I use to make sure everything works. (I'm not sure how to do automated tests for a package like this, so go test will say no tests found for now; sorry.) If you are cross-compiling to Windows, you will need to have a very specific Go setup which allows multiple cross-compilation setups in a single installation; this requires a CL which won't be in Go 1.3 but may appear in Go 1.4 if accepted and both windows/386 and windows/amd64 set up for cgo. (This is because ./test.sh on Windows targets invariably regenerates the zconstants_windows_*.go files; there is no option to turn it off lest I become complacent and use it myself.)

Finally, please send documentation suggestions! I'm taking the documentation of this package very seriously because I don't want to make anything ambiguous. (Trust me, ambiguity in API documentation was a pain when writing this...)

Thanks!

(Note: I temporarily disabled Travis.ci; if I can figure out how to do good cross-compiles with it, then I can put it back.)
