apps/graphics/twm4nx: Fix several errors associated with the NxTerm buttons. Most changes involved fixing crashes with the exit button is pressed. Now the NxTerm windows behave well. However, they are not receiving console input so there is still more to be done.
apps/graphics/twm4nx: Various fixes to get the NxTerm window to come up properly. It does now come up okay, but the system basically loses its mind thereafter. Goods good until some buttons are pressed.
apps/graphics/twm4nx: Simpify application startup.
apps/graphics/twm4nx: Fix some errors in debug statements.
apps/graphics/NXWidgets/: NXWidgets::CNxWidgets: Fix some issues with returned values. On setting the widget size or position, it was returning false if there was no change in size or position. Many places in the code were treating the false return value as an error.
apps/graphics/twm4nx: Fix a couple of errors in the unused resize logic: It was not hiding the resize menu to it appeared as a artifact in the uppler left hand corner. Was calling setSize() on the window instead of getSize(). That was causing errors because the size being set was uninitialized.
apps/graphics/twm4nx: Add missing event generation logic when a window is closed.
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: This resolves the problems noted in the previous commit comments. Window events are now communicated properly to the appliation-specific event handler. Menus now seem to be receiving events and working well.
apps/graphics/twm4nx: Revamp application event handler. Better design but still crashes when a main menu entry is clicked.
apps/graphics/twm4nx: First cut at application window event distribution. Has some issues. Not ready for prime time.
apps/graphics/twm4nx: Add more controls for the events that will be generated on basic window redraw, mouse/keyboard input, and keyboard input.
apps/graphpics/twm4nx: Add a 'Desktop' item to the main menu that will iconify all windows and menus and just show the open desktop.
apps/graphics/twm4nx: Remove some unnecessary twiddling with widget settings.
apps/graphics/twm4nx: Correct an error in how menu windows are created.
apps/graphics/twm4nx: Use button array vs list box for menus.
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: The Icon Manager now adds a Main Menu entry that will de-iconify the Icon Manager or raise to the top of the hieararchy if not iconfified. This is useful when there are many open windows.
apps/graphics/twm4nx: In resize operation, don't let window get narrower than the minimum toolbar width.
apps/graphics/twm4nx: Add logic so that the main menu is place at (or near) the position where the background was clicked.
apps/graphics/twm4nx: Better integrate menus and iconifiction: Bringup up a menu is like de-iconifcation, except there is no icon to be erases; taking down a menu is like iconification except that there is no icon to present.
apps/graphics/nxwidgets: Add methods to all windows to query if a window is visible or hidden.
apps/graphics/twm4nx: Use NxWidgets methods which work in all contexts instead of trying to come up with a way to know if a window is displayed through complex flags.
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.
apps/graphics/nxwidgets: CWidgetControl::handleLeftClick now returns a value to indicate if the click was actually processed or not. CWidgetControl::pollMouseEvents: Correct return value.
apps/graphics/twm4nx: CBackground::event(): Implement logic to handle a left click on the background and to bring up the main Menu. CWindowEvent: Extend message to distinguish between keyboard and mouse input. Mouse position and buttons now accompany the mouse input data. CMenus: Add methods to query and control the visibility of the menu.
apps/graphics/twm4nx: Additional redesign. Window draggin now sort of works in an unreliable hurky-gurky way. More to be done.
apps/graphics/twm4nx: First cut at redesigned dragging logic
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.
1. A memory corruption issue that occurs from a paste operation that would overflow the fixed buffer size for keyboard processing.
2. A stall in getch() processing when there are cached keycodes in the termcurses emulation (tcurses_vt100.c).
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.
