apps/graphics/twm4nx: Adds some colors and better style control to support the CONTEMPORARY theme. Still getting a few artifacts on the display.
apps/graphics/twm4nx: Use custom CWidgetStyle to force Icon background to match selected desktop background.
apps/graphics/nxglyphs: Add more modern looking button images for the Twm4Nx CONTEMPORARY theme
apps/graphics/twm4nx: Add some definitions to support Themes. Background image is now optional.
Squashed commit of the following:
apps/graphics/twm4nx: The calibration seems to be functional. Needs more testing.
apps/graphics/twm4nx: Extend event handling to support receiving raw, uncalibaated touchscreen inputs. This is needed for touchscreen calibration.
apps/graphics/twm4nx: Extend event handling to support shutting down of externally controlled windows. This is need to end the calibration sequence.
apps/graphics/twm4nx: CCalibration now compiles okay, but is missing event handling logic for touchscreen input and for window termination.
apps/graphics/twm4nx: Move application-related files into different directories to separate them from the core Twm4Nx files.
apps/graphics/twm4nx: A little more progress on calibration display.
app/graphics/twm4ndx: Add files that will support a calibration display. This initial commit is simply the calibration display from NxWM and is not hooked into the configuration or build systems.
apps/graphics/twm4ndx: Compile out cursor support if we are using a mouse
Squashed commit of the following:
apps/graphics/twm4nx: Revamp the event system to support notification of external applications when the window is being closed.
apps/graphics/twm4nx: A little NxTerm progress
apps/graphics/twm4nx: Clean up some logic associated with use of multiple Icon Managers.
apps/graphics/twm4nx: Add CNxterm to the build. It is a long way from compiling.
apps/graphics/twm4nx: Mostly cosmetic stuff.
apps/graphics/twm4ndx: In icon manager, fixing some places where width was used when height was intended. Fixe uninitialized variable.
apps/graphics/twm4nx: CWindow: Add a global function that can be used to determine the minimum width of a window. If the window is set to a width smaller than this, then toolbar items will overlap and the toolbar will be corrupted. This is a global function (rather than a method of CWindow) because in some cases, this minimum width must be known before the window is created.
apps/graphics/twm4nx: CMenus now uses CWindows, rather that raw NX windows. This rippled through to many other things due to conflicts between NUL-terminated C strings and NXWidgets::CNxStrings.
graphics/twm4nx/src/ciconmgr.cxx: Correct initial window size and position in the upper righthand corner; Need to fill draw the button array immediately on window creation.
graphics/twm4nx/src/cwindow.cxx: Need to fill the toolbar initially with the widget background color.
apps/graphics/twm4nx: Fix various bugs found in bringup: Re-order object instantiation to account for inter-object dependencies. Correct mq_receive() buffer size. Fix a backward comparison.
apps/graphics/twm4nx: Twm4Nx debug can now be separately enabled so that it does not get overwhelmed by other graphics debug output.
version 1.0.10 to NuttX NX windows server. No, a port is not the right
word. It is a re-design of TWM from the inside out to work with the NuttX
NX server. The name Twm4Nx reflects this legacy. But Twm4Nx is more a
homage to TWM than a port of TWM.
The original TWM was based on X11 which provides a rich set of features.
TWM provided titlebars, shaped windows, several forms of icon management,
user-defined macro functions, click-to-type and pointer-driven keyboard
focus, graphic contexts, and user-specified key and pointer button bindings,
etc.
Twm4Nx, on the other hand is based on the NuttX NX server which provides
comparatively minimal support. Additional drawing support comes from
the NuttX NxWidgets library (which necessitated the change to C++).
Twm4Nx is greatly stripped down and targeted on small embedded systems
with minimal resources. For example, no assumption is made about the
availability of a file system; no .twmrc file is used. Bitmaps are not
used (other than for fonts).
The TWM license is, I believe compatible with the BSD license used by NuttX.
The origin TWM license required notice of copyrights within each file and
a full copy of the original license which you can find in the COPYING file.
within this directory.
STATUS:
This port was brutal. Much TWM logic was removed because it depending on X11 features (or just because I could not understand how to use it). The logic is partial. A lot more needs to be done to have a complete system (hence, it is marked EXPERIMENTAL). The kinds of things that need to done are:
1. Update some logic that is only fragmentary for how like resizing, and menus.
2. Integrate NxWidgets into the windows: The resize menu needs a CLabel, the menus are CListBox'es, but not completely integrated, the Icon Manager needs to be a button array.
3. Resit Icons. They are windows now, but need to be compound widgets lying on the background.
4. Widget events are only partially integrated. A lot more needs to be done. A partial change to thoe event system that hints at the redesign is in place but it is far from complete.
