apps/graphics/twm4nx: Revise logic to detect clicks on the background image. The original implementation had some side effects.
apps/graphics/twm4nx: Remove some remaining, unused stuff from TWM that was never used. Menus need to close after the 'terminal' selection is made. Otherwise, the menu can become buried under a newly open menu and not easily recovered.
apps/graphics/twm4ndx: Add a 'critical' bit to the eventID. While resizing, all events will be ignore except those marked critical.
apps/graphics/twm4nx: CBackground now brings up the main menu if the background image is click. This makes the behavior the same across all of the background except when an icon is clicked.
apps/graphics/twm4nx: Adds some colors and better style control to support the CONTEMPORARY theme. Still getting a few artifacts on the display.
apps/graphics/twm4nx: Use custom CWidgetStyle to force Icon background to match selected desktop background.
apps/graphics/nxglyphs: Add more modern looking button images for the Twm4Nx CONTEMPORARY theme
apps/graphics/twm4nx: Add some definitions to support Themes. Background image is now optional.
apps/graphics/twm4nx: Fix an uninitialized variable that was causing toolbar buttons to randomly come up enabled or disabled. Remove some unused event definitions.
apps/graphics/twm4nx: Fix a calibration screen startup issue. Make an initial calibration scrren optional
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/twm4nx: Fix a bad width calculation.
apps/graphics/twm4nx: Debugging resize. Only partially functional.
apps/graphics/twm4nx: Forgot to install the IEventTap instance. No resizing kind of works, but I can't get out of it! There is a basic problem in the window needs to be updated for the new size and there is no mechanism in place to do that (at least not with RAM backed windows).
apps/graphics/twm4nx: Add missing part of the resize logic. Initial testing is mixed. The resize window appears, but nothing else good happens. No hardfaults though.
apps/graphics/twm4nx: This is a complete redesign of the CResize class. Unverified on initial commit.
apps/graphics/twm4nx: Commit of in-progress resize changes
apps/graphics/twm4nx: In the Icon Manager, do not use the window name to identify which button press corresponds to which Window. Window names are not unique. Instead, it now keeps track of thich row x column was assigned to the window name. That row x column uniquely associates a window with a button and does not depend on the window name in any way.
apps/graphics/twm4nx: Fix an error in event notification sent by the Icon Manager when a window is selected.
apps/graphics/twm4nx: Correct logic in Icon Manager for the case where the number of windows causes the Icon Manager to increase in size by one row.
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/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.
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.
