Twm4Nx is a port of twm, Tab Window Manager (or Tom's Window Manager)
|
|
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
|
|
======
|
|
2019-04-28: This port was brutal. Much TWM logic was removed because it
|
|
depended on X11 features (or just because I could not understand how to
|
|
use it). The replacement logic is only mostly in place but 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 things like resizing.
|
|
Resizing events should be be generated when user pulls to right,
|
|
left, top, bottom, etc. None of that is implemented.
|
|
2. Left click on background should bring up a user provided main menu.
|
|
Right click should bring up a window list (like the icon manager???)
|
|
3. For TWM-like behavior, a window frame and toolbar should be highlighted
|
|
when the window has focus.
|
|
4. A right click on the toolbar should bring up a window-specific menu.
