apps/graphics/tmw4nx and apps/graphics/slcd: This seems the last of the show stopper bugs. All seems functional.
apps/graphics/slcd: Correct some errors found in early texting. Now the Twm4Nx::CClock window comes up, but there are problems with the way that the segments are being displayed.
apps/graphicx/twm4nx: CClock is complete and compiles correctly. Crashes with a hardware when the clock is selected from the Main Menu, however.
apps/graphics/slcd: With these changes the CSLcd class now compiles
successfully. Still untested.
apps/graphics/slcd: Finish off rendering. Hook into configuration and build system.
apps/graphics/nxglyphs: Add images that will eventually be used for clock icons
apps/graphics/slcd: Completes all CLcd methods except for rendering to the window.
apps/graphics/slcd: Add beginning of SLCD class.
Add ASCII to SLCD character mapping.
apps/graphics/slcd: Represent segments as runs rather than trapezoids. Trapezoids will be synthesized later.
A little more SLCD logic
apps/graphics/slcd: Flesh out more trapezoids in the decomposition.
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
apps/graphics/twm4nx: Clean up some build issues.
apps/graphics/nxglyphs: Remove some warnings due to coupling with NXWM.
apps/graphics/twmndx: Separate out the main() entry point for ctwm4nx.cxx. There is functionality there that does not involve CTwm4Nx and so it is better if the main function were totally separate.
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: Replace most usage of NUL-terminated C strings with NXWidgets::CNxString.
apps/graphics/twm4nx: Add initial support for the main menu. The main menu will come up when a left click is performed on the background. The main menu is used for starting applications. The adds the CMainMenu class that implements the main menu and an IApplication interface class the provides th template for how any external C++ application can add itself to the Main Menu.
Still missing is the logic that responds to the meny item selection and sends the event to the Main Menu as well as the logic in the Main Menu that handles the event and either brings up a sub-menu or starts and application.
Things are still basically functional after these changes, but my gut feeling is these changes added some instabilities that will need to be smoothed out.
apps/graphics/twm4nx: Remove Icon Windows; replace with IconWidgets that are draw on the background.
apps/graphics/twm4nx: Add CIconWidget event generation.
apps/graphics/twm4nx: Add event handling logic to CIconWidget.
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.
