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: Try to improve icon text spacing. Not noticeably better, however.
apps/graphics: Split long icon title on two lines below the icon image.
apps/graphics/twm4nx: Both iconification and de-iconification work.
apps/graphics/twm4nx: Various fixed toward de-iconifying a window. Progress but still not there yet.
graphics/twm4nx/src/window.cxx: Add flags to CWindow initializer to support customization of toolbar buttons and other window properties. Add framework to handle toolbar button presses. Window minimization (aka, iconification) does not work.
graphics/twm4nx/src/input.cxx: Add support to scaling touchscreen. Not needed for the current testing because the touchscreen naturally matches the display size. But will be needed, along with calibration scren, in the future.
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.
apps/graphics/NxWidgets: Fix a possible deadlock condition when waiting for window geometry data that will never come. Fixed by re-requesting geometry data if we don't already have it.
apps/graphics/twm4nx: Add some debug output.
apps/graphics/twm4nx: Rethink how background events are handled.
apps/grephics/twm4nx: Expermimental organization to capture background events.
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.
graphics/twm4nx/src/ciconmgr.cxx: Integrate use of CButtonArray; implement first cut at event handling.
graphics/nxwidgets/src/cbuttonarray.cxx: Add a method to CButtonArray that will allow us to dynamically resize the array (at the cost of losing all button labels).
graphics/twm4nx/src/ciconmgr.cxx: Add some fragments of CButtonArray logic.
graphics/twm4nx/src/cwindow.cxx: Finishes first cut at window event management.
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.
apps/system/nxplayer: Fix some logical errors from recent comments. They broke the build of the nxplayer as a library vs. a task. apps/graphics/nxglyphs: Fix yet more namespace problems.
graphics/nxwm/src/nxwm_main.cxx: Move from graphics/nxwidgets/UnitTests/nxwm/nxwm_main.cxx.
apps/graphicx/nx*: Fixes numerous build issues mostly associated with include paths and namespaces.
apps/nxglyphs: Decouple (mostly) from nxwidgets and nxwm so that they can be used elsewhere. Creates include/graphics/nxglyphs.h
apps/graphics/nxglyphs: Put all NxWidgets and NxWM glyphs into a common directory where they can eventually be shared. Not very sharable at the moment due to header file entanglements. Need a separate nxglyps.hxx header file.
Separate nxwidets and nxwm into separate directories. Remove old, common NxWidgets directory.
NxWidgets improvements
* NxWidgets: fix garbage returned when CCycleButton::getValue() is called after removeAllOptions().
It's a bit questionable whether returning 0 here is reasonable or
if it would be better to assert(). But either is better than reading
into random memory and returning a garbage value.
* NXWidgets CScrollingPanel: Don't draw outside the widget area.
The port->move() function doesn't support clipping the
copied area to the client area, so we have to manually
calculate the part that can be moved without going outside
the widget.
* CNxString: Add string + operator and ::format() function
* CNumericEdit: Add option to include unit name after the value
* NxWidgets: CNxWidget: Make useWidgetStyle() public
Makes it easier to update styles when multiple controls are nested.
* NxWidgets: Add CLabelGrid control for displaying text in grid format.
