tekUI Changelog

Compiler tool can now amalgate Lua programs into stand-alone executables

Compiler tool: Now works with Lua 5.1/5.2/5.3 using the method shown in lua-amalg by Philipp Janda, LUAARCH switch is no longer needed, module sampling is now done in a LuaExec task, no module statistics files needed, now works under Windows, too

Building a standalone tekUI executable now works under Windows and using cross-compilation

Some X11 font issues corrected

Windows display driver could try to send tekUI messages to foreign windows, leading to a crash, corrected

Exec: added semi-internal function TFreeTask(), user tasks are now freed in destructor context after their return from exec, minor cleanup in memory functions

1.11:

HAL: fix for broken timer device under Windows, MMTimer timerequest abort on signal arrival did not work for ages, corrected, giving e.g. TWaitTime() in Windows display driver much better response times and smoother updates.

Luaexec: added functions getmsg, getname, getsignals, run, sendport, sendmsg, signal, sleep, wait, waitmsg, waittime, child methods abort, join, sendport, sendmsg, signal, terminate, including error propagation through running tasks, added childtask example

TEKLib: Added support for mulithreaded, lazy singleton creation

Visual: Module instances' init requests are no longer reused, getting rid of nearly incomprehensible trickery that did not work properly

Added basic support for native Linux framebuffer and event interface. Support can be compiled into the raw framebuffer display driver.

Raw framebuffers automatically recognize the need for a backbuffer now, e.g. when a VNC server is running on top a Linux framebuffer and the pixel formats differ. Backbuffer support can also be enabled explicitely using ui.ExtraArgs = "fb_backbuffer=true"

Linux framebuffer keymaps are compiled-in for now, added tool etc/keymap2c for conversion; default is /usr/share/keymaps/i386/qwerty/us.map.gz

1.0:

New versioning scheme established. The 1.0 version does not reflect some exceptional achievement, and the major version will be changed more frequently in the future. The versioning scheme resembles Lua's in that new major versions indicate some nontrivial API changes. The UI library now contains a version that reflects tekUI's overall package version number.

The document generator now accepts C source files, too, for classes which have been written in or ported to C. The notation is the same, so the current function headers only need to be enclosed in C comments.

tekUI example class written in C: Fixed a bug that thwarted child classes to inherit from the example class. Rounded out the registration prolog, added tek_lua_register() that isolates 5.1/5.2 compatibility and simplifies registration

Raw framebuffer: Improved window focus management, fixed memory leak

String class: documentation added

Application:up() added

Added examples demonstrating communication with child processes and datagram socket server; socket and filestream communication are no longer part of the display drivers, but now available throughout tek.lib.visual

Rendering of color gradients corrected

New Input and TextEdit classes added, the TextInput class is obsolete. Input is largely compatible with TextInput. The new class supports multiline, proportional fonts, smooth scrolling, MaxLength, Size, passwords, selections, and an internal clipboard, which can be shared with the system clipboard (currently implemented in the X11 driver)

RawFB (in-memory) framebuffer display driver added, which is recursive: Allows another display driver to be plugged in as its rendering back-end

Added Lua 5.2 support, and no longer uses Lua internal API functions

Added gradient support, available via stylesheets

RawFB: Added LibVNCServer support. Applications can now be shared with the network, running headlessly or with an additional native display

Added 'klinik', 'stain', 'gradient' stylesheets

Default border now supports border-legend-align attribute, bug fixed in focus border rendering

Element: Cascading stylesheets did not incorporate an element's hardcoded class properties correctly, corrected, getPseudoClass() added

ScrollGroup: Reduced object tree complexity in some cases, some checks added

ui: Added FL_UPDATE, typo in "BckSpc" symbolic key name corrected, added MSG_REQSELECTION, added FL_RECVINPUT, FL_RECVMOUSEMOVE, FL_CURSORFOCUS, now automatically loads "default" as the first stylesheet unless "minimal" is explicitely given in the THEME variable

Area: setFlags(), checkClearFlags() added, taking care of FL_UPDATE bubbling up in the graph on setting FL_REDRAW, FL_REDRAWBORDER, FL_CHANGED. getNext(), getPrev() now have an optional "recursive" mode argument. added getDisplacement(), getMsgFields(). checkHover() renamed to checkHilite(); getBG() now returns additional position-independency info for better support of transaprent backgrounds, getMargin and getPadding are now written in C

Group: now descends only into elements with FL_UPDATE set during updates, which reduces the overhead for small, partial refreshes. remMember() now unweights a Group's remaining elements; no longer passes messages to disabled or inactive elements

Lister: No longer unselects entries in cleanup(), more sanity checks

Application: User message handler is now established in new(), added FocusWindow attribute

Display, Visual: Added support for bold and italic in fontnames and with openFont(), better default/fallback fonts, added symbolic color "bright", getattrs() now supports query of selection and clipboard, getPaintInfo() added

DirList: path/location field bugs fixed, some improvements especially in regard to keyboard control

X11 display, Visual, Applications: Added support for selections and clipboards. tekUI input messages are now userdata encapsulations of TEKlib messages, passed into Lua space, unpacked only on demand when accessed, and replied explicitely using reply() or implicitely through garbage collection. messages can now perform a roundtrip through Lua space back to originator

TEKlib: Added more support for message port hooks

PopItem: Some initialization and other problems corrected

Widget, Window, PopItem: Added some right mouse button support

Widget: improved doubleclick state detection, now known in onPress() etc., Hover attribute and onHover() removed, simplified activation model based on Hilite attribute, now all widgets receive FL_RECVINPUT, interactive elements additionally receive FL_RECVMOUSEMOVE
