0.8.6 (December 21, 2007)
-----
Cursor
- Don't load default cursor if LITE_NO_CURSOR is exported.
Utilities
- Fixed bug in image loading routine for non-ARGB images and no explicit format passed.
Show errors in image loading routine.
bench tool
- Disable alpha channel and window theme.
0.8.5 (December 14, 2007)
-----
- Fix bounds checking for LiteButtons to correctly handle negative
coordinates, like those generated when you move to the left or above
the button.
- Correctly generate enter/leave events when the LiteBox hierarchy changes.
- Release a LiteBox's drag_box when containing window is left. Since mouse
is grabbed during drag, this only happens when other parts of the system
adjust the window hierarchy
- Fixed width/height mixup in lite_get_window_size().
- Fixed signed/unsigned types and warnings.
- Check for event_buffer != NULL in prvlite_wakeup_event_loop().
- Added missing call to prvlite_wakeup_event_loop() in lite_update_window().
0.8.4 (March 1, 2007)
-----
- Fixed issue with timing of window update and window resizing leading
to graphics glitches
- Reworked window destruction again to make sure that windows aren't
completely destroyed until they are no longer used by the event loop
mechanism
- fixes to ensure that a window's drag box won't be incorrectly set
- change order of event loop so window refresh during event queue
processing occurs without also triggering timeouts
- validation checks added to some LiteCursor calls on debug build
- window validation added to many LiteWindow calls on debug build
0.8.3 (December 13, 2006)
-----
- New API: lite_destroy_all_windows - calls lite_destroy_window
on all windows in system from newest to oldest
- New API: lite_rebase_window_timeouts - used to adjust all window
timeouts when the system time changes
- New API: lite_window_event_available - returns true if any
events are queued up or any timeouts are ready.
- New API: lite_set_window_bounds - used to move and resize a
window in one on-screen operation
- Const correctness parameter changes for lite_get_font_filename(),
lite_set_window_background()
- lite_update_box() and internal find_child() rewritten to be
non-recursive for speed purposes
- more fixes around window destruction and properly releasing
interfaces and freeing memory
- lite_init_box now disallows boxes with negative height or width
- modified update code to use memmove instead of memcpy to fix overlap
problem
- lite_window_event_loop will force an update at least once every 200
milliseconds if one is needed and hasn't happened yet
0.8.2 (October 14, 2006)
-----
- expanded the LiteBoxType enumeration to have different items for
each LiteBox and LiteWindow type defined in the library, with
special ranges for expanding the number of types for client
libraries
- updated code to fix stdbool.h warnings (Ville Syrjala)
- patch to support vertical sliders (Pierre-Hugues Husson)
- changed window update loop to be more efficient
- fixed bugs with new window destruction code
- fixed bug with routing of resize events to not-yet-displayed windows
- fixed a memory leak with freeing window memory on DWET_DESTROYED
- fixed a IDirectFBLayer reference leak in lite_change_cursor_opacity
- changed lite_enqueue_window_timeout and lite_enqueue_idle_callback
to never return the value 0 as the ID
- fixed bad return value for lite_remove_window_timeout
0.8.1 (September 20, 2006)
-----
- new API: lite_set_window_enabled - this function will tell a window
if it should handle events that are sent to it. DESTROYED events
will always be handled.
- fix to handle_wheel to ignore wheel events for a box if it ignores
keyboard events
- optimized shared library lookup tables by using -Wl,-O1 option for gnu ld
- optimized lite_set_active_font call by having it avoid a cache lookup
just to validate that a font has been loaded
- reworked window destruction extensively to work correctly with DFB's
window destruction model. You should use the window's box->Destroy
callback for cleanup code, while window->OnDestroy is just used to
catch the DWET_DESTROYED message that will get sent later
- removed the nesting level concept from window timeouts, as it led to
hard to fix cases. If you want a timeout to not be called, make sure
to remove it before opening a new window.
0.8.0 (August 30, 2006)
-----
- new API: lite_destoy_box_contents - destroy a LiteBox and its children, but
don't free the LiteBox pointer. Used by LiteWindow to destroy children while
delaying deallocating LiteWindow until the DFB_DESTROYED event.
- LiTE now honors the OnDestroy method of LiteWindow objects. This will be
called when DirectFB sends the DFB_DESTROYED event for a window. The
LiteWindow is then freed.
- Fixes to modal window handling to better handle destruction of the modal
window and restoring the correct modal window when a window is non-modal.
- Lite window themes now include settings for the a color and position
of the window's title
- When a window has been resized but the resize hasn't taken effect,
updates to the window will be discarded until the resize occurs,
since the resize will force a redraw of the whole window.
- Lots of minor bug fixes and cleanups.
- This version requires DirectFB 0.9.26 (currently in development)
0.7.2 (May 5 2006)
-----
- New maintainer, Ben Combee <ben.combee@gmail.com>
- Window updates are now collected into up to four different regions
which should make updates faster by reducing the total area updated
when distant LiteBoxes are all updated
- fix to correctly restore modal windows and to deal with windows created
while we're tracking a mouse event
- fix to not update boxes when they are invisible
- fix for drawing windows with correct opacity
- New API, lite_get_font_filename, to get the filename associated
with a font
- rewrote lite_event_loop to add support for idle callbacks and to fix
problems with timeout callbacks
0.7.1 (Feb 2 2006)
-----
- New API, lite_on_raw_window_mouse_moved(), this installs a callback for any mouse moved
events before LiTE processes these events.
- Fixed bug with the drag box not always properly updated.
- Avoid using fixed DFBSurfaceBlittingFlags, instead record them into the LiteImage object
and have DSBLIT_BLEND_ALPHACHANNEL as default.
- New function, lite_set_image_blitting_flags() to set the blitting flags for the automatic
image updates in LiteImage.
0.7.0 (Jan 22 2006)
----
- Make sure window drag boxes are set to NULL in case it's a child that's been removed.
- Return from the event loop in case the window that is used in the event loop is destroyed.
- Make sure to flush updates in the event queue in case items have been updated by
timeout callbacks.
- New API, lite_on_raw_window_wheel() API to install callbacks that will intercept
raw wheel events before they are processed.
0.6.5 (Dec 20 2005)
-----
- Defer opacity change of a window (making it visible) until it has just been
updated once.
- Remove clear of the window context during creation, instead just enqueue an update.
- Lock the mutex while updating a font ref count.
- If a null region is passed for an update window call, update the whole window.
- Focus bug fixes for focused boxes.
- Modal state is now handled outside the actual modal window, i.e. pick up events
outside the modal window region.
- Cursor hotspot control in the LiteCursor structure.
- lite_set_cursor_hotspot() for setting the hotspot for specific cursors.
- Default hotspot values for system cursor defined in lite_config.h
- New feature to add LiteTimeoutFunc callbacks into the LiTE event loop with
lite_enqueue_window_timeout() and lite_remove_window_timeout().
0.6.4 (Nov 18 2005)
-----
- Bug fixes
- Lite Doxygen documentation structure changes
- Better control of LiteBox is_visible flag so groups of child hierarchies
could be shown or hidden.
- New LiteWindow flag, LITE_WINDOW_FIXED, used for making sure a LiteWindow
can't be moved, resized, or hidden by left or right-mouse clicks.
- Renaming of callback functions so they have a Lite prefix.
0.6.3 (Nov 7 2005)
-----
- Fixed bugs related to D_MALLOC use.
- Removed too aggressive testing of LiteBox* objects in litebox.c APIs.
- Patch from Ben Combee making it possible to hide groups of LiteBoxes.
0.6.2 (Oct 28 2005)
-----
- Use D_MALLOC et friends from direct/mem.h for tracking down memory leaks and so forth.

- New internal APIs exported, lite_append_child() and lite_remove_child() for parent
child array manipulations.
- Documentation updates and fixes.
- New LiteWindowFlags, LITE_WINDOW_HANDLING_EVENTS for indicating that events are happening
and LITE_WINDOW_DESTROYED for delayed window destruction.
- Delayed window destruction function so windows are destroyed later, not immediately in the
event loop.
- Extensive use of D_DEBUG_AT inside various components for stating the internal changes.
- Fixed on_button_up so the callback is only triggered if the mouse event happens inside
the targeted LiteBox.
- Bug fix, use of D_STRDUP in all cases the string has been created with
D_* macros, and other similar fixes.
- And even more bug fixes.
0.6.1 (Oct 11 2005)
-----
- Documentation fixes.
- Alternate way to make a true global event loop independent of a created window. Enable with
the NEW_EVENT_BUFFER in window.c. An alternate event queue is now created as part of lite_init().
- private functions supporting attachment to a global event queue.
- Moved event handling code from window.c to event.c.
- New API, lite_get_window_size() that returns the true window size from IDirectFBWindow interface
function.
- API name change, lite_on_user_event() is now called lite_on_window_user_event() to reflect that it's tied
to a specific window.
- API name change, lite_on_universal_event() is now called lite_on_window_universal_event() to reflect

- New macro, LITE_BOX_PARAMETER_CHECK, to check if a passed in LiteBox is a valid struct or not.
- Most window public APIs now use LITE_WINDOW_PARAMETER_CHECK.
0.6.0 (Sept 26 2005)
-----
- Various bug fixes related to the event handling, and window child handling.
- Fixes in code base to make sure various pointer variables are initialized to NULL.
- New window callback, lite_on_universal_event() to catch DFBUniversalEvents.
0.5.3 (Sept 7 2005)
-----
- New APIs, lite_window_set_creator() and lite_window_get_creator(), from Damian
and Kent, to save information about the window who created a specific LiteWindow.
This is then used in the modal window loop to forward all input events to a window
that was created by a modal window, making it possible to have child windows that
are bigger in size than the actual modal window.
- Updates of LiteWindow's height and width values when calling lite_resize_window().
- Move the default theme global variables into .c files and place extern definitions
in the .h files, this to make C++ compilations work without errors.

-----
- Bug fixes.
- Added extern "C" wrappers around all header files for C++ use.
- New global callback for window event handling installed with
lite_on_window_event(). See documentation for details.

-----
- New internal event alive flag that could be disabled/enabled via internal
APIs, this to better control when to exit an event loop.
- New function, lite_set_exit_idle_loop(), when this is enabled the event
loop will exit if there are no pending events present.
- Guard all stack-based pointers with NULLs to avoid strange problems later
when any of such pointers are tested.
- Fixed the timeout values for lite_window_event_loopso that seconds and
milliseconds are passed to WaitForEventWithTimeout.
- Other minor bug fixes.
0.5.0 (July 10 2005)
-----
- Many internal function and variable name changes to conform to coding style.
- New constants liteFUllWindowOpacity and liteNoWindowOpacity.
- LiteTheme extensions, all widgets now have a specific theme they could use,
or use the default theme (not all widget have specialized themes yet).
- Public APIs for widgets now take a DFBRectangle and a LiteTheme.
- LiteWindow is taking into account the LiteTheme background colors when initializing.
- New unit test framework inside tests to test out various parts of LiTE each time
it is changed. This includes performance timing tests.
- More unit tests for various widgets and LiTE functions in place.
- New API, lite_exit_event_loop(), when called will exit the current event loop.
- New API, lite_get_layer_interface(), returns the opened display layer.
- Fixes to make sure titles in windows could be drawn even if the Theme does not
include a font specification.

the layer to DLSCL_ADMINISTRATIVE.
0.4.3 (June 24 2005)
-----
- All of the public headers have now Doxygen documentation.
- Reformatted source code so the same look and feel is across all files.
- lite_init_window() now also takes a DFBRectangle and a LiteWindowTheme.
- lite_window_setmodal() renamed to lite_window_set_modal().
- Three new cursor APIs, lite_hide_cursor(), lite_show_cursor() and
lite_set_cursor_opacity().
- New function lite_free_window_theme() to release window theme resources.
- New configuration constant, DEFAULT_WINDOW_MINIMIZE_SIZE.
- render_title() is now more flexible and allows window themes with no
fonts as well as no title set for the window so that the top level
frame could be rendered.
0.4.2 (June 17 2005)
-----
- The window theme handling is now broken out so that a LiteWindowTheme
could be passed into lite_new_window(). There's a liteDefaultTheme,
liteNoTheme, or a custom theme could be passed in. As part of this
the lite_new_window() API changed, in addition to the LiteWindowTheme
it now uses DFBRectangle to pass in the window size, this way we
avoid functions with too many parameters.
- The theme handling has a new base structure, LiteTheme.
- All header file top parts have Doxygen @brief statements.
- New compile time lite_config.h flag, LOAD_DEFAULT_THEME, on by default,
if disabled, no default themes are built. The environment variable
LITE_NO_THEME is also still operational.
- New directory called tests where LiTE unit tests are placed, two
new unit tests, window and nothemewindow.
- All user-provided callbacks now return DFBResult, this so we could
test or a value not being DFB_OK and stop event flows and so on.
- New callback hook that is installed with lite_on_raw_mouse(), this
callback triggers with mouse event information before the modal state
and LiteBox mouse handling has happened. This makes it possible to
find out if a parent window has a mouse click in order for the child
window to close itself (for example with popups.)
- New callback hook that is installed with lite_on_raw_keyboard(), this
callback triggers with mouse event information before the modal state
and LiteBox keyboard handling has happened.
0.4.1 (June 10 2005)
-----
- New API, lite_get_event_buffer() to return the DFB event buffer pointer
- New LiteBox flags, is_visible, for disabling/enabling drawing, as well
as for event control (no events passed to a disabled LiteBox).
0.4.0 (June 2 2005)
-----
- Various bug fixes (see ChangeLog for details), mostly related to fixing
issues when multiple LiteBox entries are dynamically created and destroyed.

- Modal support for Windows by enabling the modal window flag, this changes the event
loop so that only the frontmost modal window will receive events.
- Other LiteWindowFlags for indicating if the window could be minimized or resized.
- In lite_reinit_box_and_children(), maintain the font information when cloning the boxes.
- New global cursor that is by default set to a default cursor, but could be set to
any valid LiteCursor during runtime. This makes it possible to have dynamic cursors in
the LiTE environment.
- New cursor APIs: lite_get_current_cursor(), lite_set_current_cursor(), lite_load_cursor_from_file(),
lite_load_cursor_from_desc(), lite_free_cursor(), lite_set_window_cursor().
- New font API, lite_ref_font() for virtually cloning font instances.
0.3.1 (May 12 2005)
-----
- New multi-window event loop where multiple windows share the same event buffer.
This will make it possible to write modal and modeless LiTE applications.
- Fixed a problem with the box-parent's child array slot not updated and compacted when
children are removed from a box.
- New LiteBox field, handle_keys, used to disable and enable key handling in LiteBox instances.
- LiteWindow has a separate init call, makes it possible to subclass LiteWindow (similar
to subclassing LiteBox)
- New lite_get_current_key_modifier() API to return the current key modifier.
- Work on two new LiteWindow function callbacks, OnBoxAdded() and OnBoxToBeRemoved(), triggered
when a box is added to an underlying box hierarchy, or to be removed.
- Code contributed by Andy Stewart and Damian Kowalewski.
0.3.0 (Mar 31 2005)
-----
- Lite's event loop is now based on a single event buffer shared across multiple window instances.
- LiteCursor structure outside LiteWindow.c, inside cursor.h
- Many more functions now also return DFBResult values.
- Test of keeping the grabbedpointer window pointer around for possible release of this window in odd cases.
- Wheel support, LiteBox OnWheel where widgets could make use of wheel events, lite_on_window_wheel to
install a global event handler for the window where wheel events are generated.
- Removed lite_on_idle() callback installer as there are better and more reliable ways to generate
idle time handlers.
0.2.2 (Mar 27 2005)
-----
- window.c event loop rearrangement so it handles any DirectFB events
- lite_on_user_event() to register a callback for arbitrary events
- lite_post_event_to_window() API to post events to the event queue
- Many more APIs now return DFBResult values, and pass in a handle for the returned structure
- Internal structure changes, LiteCursor and LiteTheme, for extending these later
- Fixed a cas where a missing UngrabPointer caused a case where an original window
still hadthe window grabbed when a new window was created
- Use of D_ASSERT statements for internal functions params passed in

-----
- LiteLabel has a field for the text color, as well as lite_set_label_color,
dfbspy.c has an example how this is used
- Default window background colors are defined in lite_config.h
- From Andy Stewart:
- define default font names in lite_config.h
- Add a DFBFontAttribute argument to lite_get_font() and lite_get_font_from_file()
- New functions, lite_set_active_font() and lite_get_active_font()
- Use macros based on DirectFB's D_BREAK and D_INFO instead of fprintf calls
- Window theme bitmap definitions placed in lite_config.h
- All internal configurations are centralized into lite_config.h
- lite_get_dfb_interface() will return the current IDirectFB interface
0.1.0 (Feb 3 2005)
-----
See ChangeLog for all the details.
- LiteWindow has global callbacks for catching keyboard and mouse events, as
well as for doing idle handling
- LiteButton has now lite_set_button_image_surface() to set individual
surfaces for bi-state and tri-state buttons
- lite_new_window takes() two params, x,y, for window positioning
