Agar Changelog

New in version 1.4.1

March 21st, 2011
  • Port to Xbox (thanks Michael J. Wood!).
  • Widget code can now use the AG_Redraw() interfaces to trigger rendering. The generic event loop uses this information to avoid unnecessary video updates -- custom event loops should be modified to test for the window "dirty" flag to take advantage of this feature.
  • Fixed compilation with --disable-legacy option.
  • Implemented AG_SurfaceFromPNG() and AG_SurfaceFromJPEG().
  • Fixed crash bug in AG_SurfaceFromSDL(); thanks trapdoor!
  • Added AG_SetJPEGQuality(), to set quality used by AG_SurfaceExportJPEG().
  • Merge --enable-foodebug into --enable-objdebug; remove lockdebug.
  • Upgrade build system to BSDBuild 2.8. Note that stale ./agar-config/ and ./agar-foo-config/ directories may break the build and should be removed before ./configure is executed.
  • Fix deadlock condition with the AG_Timeout(3) interface when timers are scheduled in reverse order; thanks to Jakob Reschke for the fix!
  • Fixed UTF8 conversion bug with 3-byte sequences; thanks Jerry Huang!
  • Fixed coordinates offset for popup menus under single-window drivers.
  • Numerous improvements to the API reference. Added AG_DriverGLX(3), AG_DriverWGL(3), AG_DriverSDLFB(3), AG_DriverSDLGL(3), AG_DriverMw(3) and AG_DriverSw(3), AG_InitGraphics() manual pages.
  • Fixed crash bug with AG_TEXTBOX_STATIC and AG_EDITABLE_STATIC.
  • Added "STRUCTURE DATA" section to AG_Window(3).
  • Added missing SDL_LockSurface() calls in sdlfb/sdlgl drivers.
  • AG_InitGraphics() can now accept driver initialization arguments.
  • Avoid use of gettimeofday() on cygwin platform.
  • MATH: Fix type conversion warnings.
  • Implemented AG_DirDlg(3) directory selection widget.
  • Implemented AG_Anim(3) interface.
  • WGL: Terminate application by exiting the event loop instead of using exit().
  • In AG_Scrollbar(3), implement AG_SCROLLBAR_AUTOHIDE option.
  • Fix compilation issues under MinGW / MSYS (thanks Joergen!)
  • WGL: Post a "window-gainfocus" event when a window is focused for the first time on creation.

New in version 1.4.0 (April 17th, 2010)

  • Added support for multiple "native" windows; rework of the low-level graphics and input device interfaces. As of this release, the available drivers are:
  • o glx (OpenGL rendering via X Window System; multiple windows)
  • o wgl (OpenGL rendering under Windows; multiple windows)
  • o sdlfb (framebuffer rendering via SDL; internal WM)
  • o sdlgl (GL rendering via SDL; internal WM).
  • New drivers can also be implemented as part of an application, the driver API is documented in AG_Driver(3).
  • Applications should now use AG_InitGraphics()to initialize the graphical interface. Backward compatibility is preserved, but AG_InitVideo()will only select among single-window graphics drivers.
  • Agar can now be built without the SDL library, where the SDL graphics driver is not needed.
  • Many improvements to the AG_Surface(3) interface, no longer rely on SDL.
  • Implement generic AG_Keyboard and AG_Mouse interfaces; allow for multiple input devices.
  • Implement widget "actions" as a generic method of handling mouse and keyboard actions per user preferences (see AG_Widget(WIDGET_ACTIONS) ).
  • Agar windows are now attached and detached using AG_ObjectAttach()and AG_ObjectDetach()against a parent AG_Driver(3); the AG_ViewDetach()function is now deprecated.
  • Added AG_Tbl(3), AG_Tree(3) interfaces to ag_core.
  • Fix handling of dynamically-allocated strings in AG_CopyVariable().
  • Implement AG_TlistUniq(), AG_TlistAddHead().
  • Important optimizations to AG_LookupClass().
  • Consistently provide plain string variants for every function accepting format string arguments. This allows for more efficient code, and avoids complications with language bindings.
  • As the window-* prefixes in events such as window-mousemotion is no longer relevant, mark them deprecated in favor of mouse-* and key-*.
  • The integer typedefs Uint8, Sint8, Uint16, Sint16, etc. are no longer made public unless _USE_AGAR_TYPES is explicitely defined.
  • Widgets such as AG_Textbox(3) now embed AG_Label(3) widgets to display their associated text labels.
  • Added AG_TextboxSetFont(), AG_EditableSetFont(), AG_ConsoleSetFont().
  • Various additions to AG_Console(3).
  • It is now possible to have the AG_Scrollbar(3) control size scaled automatically from the "visible" binding, by enabling AG_SCROLLBAR_AUTOSIZE.
  • Consistently represent color values using AG_Color(3) throughout the API.
  • Many additions and updates to the API reference.
  • Added various size hint routines: AG_ProgressBarSetLength(), AG_ScrollbarSizeHint().
  • Fixed a few memory leaks on AG_Destroy(); added demos/reinit/ test case.
  • Cursor changes are no longer performed directly from widget code. Instead, widgets now register "cursor change areas" via the AG_Cursor(3) interface.
  • Introduce AG_EventQ structure,
  • Added AG_ObjectSetAttachFn(), AG_ObjectSetDetachFn(), AG_ObjectMoveToHead()and AG_ObjectMoveToTail()functions, allowing the order of child objects to be controlled. This is used by AG_Window(3) where order is important.
  • Implemented AG_ShortFilename()utility routine.
  • VG: Implemented VG_Status(), VG_TextString(). VG_View(3) now uses widget actions.
  • The default theme now allows transparency in the color scheme.

New in version 1.3.4 (August 31st, 2009)

  • Improvements, bugfixes, and new features.

New in version 1.3.3 (November 3rd, 2008)

  • Bindings for Ada were added.
  • A math library was added. Portability and compilation fixes were made.
  • Many improvements were made to the AG_Object system; object classes are now dynamically loadable.
  • Error handling has been improved.
  • The VG library was mostly reimplemented and is now documented officially.
  • Important sizing, clipping/culling, and rendering-related fixes were made in the GUI library.
  • New widgets include Slider and Scrollview.
