libui/README.md

libui: a portable GUI library for C

This README is being written.

Announcements

• 21 May 2016
  • I will now post announcements and updates here.
  • Now that Ubuntu 16.04 LTS is here, no earlier than next Saturday, 28 May 2016 at noon EDT, I will bump the minimum GTK+ version from 3.4 to 3.10. This will add a lot of new features that I can now add to libui, such as search-oriented uiEntries, lists of arbitrary control layouts, and more. If you are still running a Linux distribution that doesn't come with 3.10, you will either need to upgrade or use jhbuild to set up a newer version of GTK+ in a private environment.
  • You can decide if I should also drop OS X 10.7 here.

Updates

Note that today's entry may be updated later today.

• 22 May 2016
  • Removed uiControlVerifyDestroy(); that is now part of uiFreeControl() itself.
  • Added uiPi, a constant for π. This is provided for C and C++ programmers, where there is no standard named constant for π; bindings authors shouldn't need to worry about this.
  • Fixed uiMultilineEntry not properly having line breaks on Windows.
  • Added uiNewNonWrappingMultilineEntry(), which creates a uiMultilineEntry that scrolls horizontally instead of wrapping lines. (This is not documented as being changeable after the fact on Windows, hence it's a creation-time choice.)
  • uiAreas on Windows and some internal Direct2D areas now respond to WM_PRINTCLIENT properly, which should hopefully increase the quality of screenshots.

Runtime Requirements

• Windows: Windows Vista SP2 with Platform Update or newer
• Unix: GTK+ 3.4 or newer
• Mac OS X: OS X 10.7 or newer

Build Requirements

• All platforms:
  • GNU make 3.81 or newer (Xcode comes with this; on Windows you will need to get it yourself)
• Windows: Microsoft Visual Studio 2013 or newer (2013 is needed for va_copy())
  • MinGW is currently unsupported. MinGW-w64 support will be re-added once the following features come in:
    • Isolation awareness
    • Linker symbols for some functions such as TaskDialog() (which I thought I submitted...)
• Unix: nothing specific
• Mac OS X: nothing specific, so long as you can build Cocoa programs

(TODO write some notes on make variables and cross-compiling)

Documentation

Needs to be written. Consult ui.h and the examples for details for now.

Language Bindings

libui was originally written as part of my package ui for Go. Now that libui is separate, package ui has become a binding to libui. As such, package ui is the only official binding.

Other people have made bindings to other languages:

• TODO list them here
