apps/graphics/twm4nx: Other toolbar buttons need to be disabled while resizing. Lots of problems if you decide to iconify or exit while resizing. CResize now disables all buttons except for the RESIZE button while resizing.
apps/graphics/twm4nx: Add an event and logic to support notification of changes in the size of a window to NxTerm.
Various updates to adapt to change in boardctl() interface.
apps/graphics/twm4nx: Correct an error in the NxTerm resize logic
apps/graphics/twm4nx: Update debug output when failures to send a message occur. The returned value of -1 is not interested, need to show the errno value instead.
apps/graphics/twm4nx: Correct the maximum size of a message. Recent changes caused message send failures because a message exceed that previous maximum size.
apps/graphics/twm4nx: Fix routing of redraw events.
apps/graphics/nxwidgets/src/cbuttonarray.cxx: Correct an error CButtonArray. Was not correctly resizing the widget when the dimensions of the button array changed.
apps/graphics/twm4nx: Trival correcion of some typos in comments.
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.
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/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/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.
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.
