NxWidgets-1.0
=============
The initial version of NxWidgets was released on March 22, 2012. This
package has been used in several projects prior to its release to open
source and is considered stable its initial release (although not all
features have been fully verified).
NxWidgets-1.1
=============
The 2nd release of the NxWidgets package as made on May 19, 2012. The
headline new feature in this release is:
* NxWM, the tiny window manager based on NX and NxWidgets. NxWM is true
multiple window manager but only one window is displayed at a time.
This simplification helps performance on LCD based products (in the
same way that a tiled window manager helps) and also makes the best
use of small displays. It is awkward from a human factors point-of-view
trying to manage multiple windows on a small display.
The window manager consists of a task bar with icons representing the
running tasks. If you touch the task's icon, it comes to the top. Each
window has a toolbar with (1) a title, (2) a minimize button, and (3) a
stop application button using the standard icons for these things. User
input via a touchscreen or mouse and keyboard is supported.
There is always a start window that is available in the task bar. When
you touch the start window icon, it brings up the start window containing
icons representing all of the available applications. If you touch an
icon in the start window, it will be started and added to the task bar.
There is a base class that defines an add-on application and an
interface that supports incorporation of new application. The only
application that is provided is NxConsole. This is an NSH session
running in a window. You should be able to select the NX icon in the start
menu and create as many NSH sessions in windows as you want. (keybard input
still comes through serial).
This initial realease of NxWM should be considered an alpha release.
All know issues are listed in the top-level TODO list.
Other important new features include:
* NxWidgets::IBitmap and NxWidgets::CRlePalettBitmap: Extended to
support different color look-up-tables (LUTs). This allows images
to be highlighted when touched, for example.
* NxWidgets::CImage: Extended to support button-like behavior. CImage
widgets now work well as touchable icons.
* NxWidgets::CWidgetControl: Add a semaphore to force clients to wait if the
size or position of the window is not yet known (multi-user mode only).
Enabled and verified creation of framed windows.
* NxWidgets::CWindowEventHandler and NxWidgets::CWindowEventHandler: Add
support for getting callbacks for window events.
* DOxygen documentation support. Contributed by Jose Pablo Carballo.
An effort is underway to simplify NxWidgets and reduce its memory footprint:
* NxWidgets::CNxWidget: Removed support for "shelving" widgets, reference
constants, and close types. Remove all support for widgets in a "vertical"
hierarchy. Now widgets exist in a flat, two-dimensional space and should
not overlap. Removed built-in modal loops.
Bug fixes include changes to the following (see the ChangeLog for details):
* NxWidgets::CRlePalettBitmap, NxWidgets::CRlePalettBitmap,
NxWidgets::CGraphicsPort, NxWidgets::CWidgetControl
