TODO for toxy
* widget
. push long message handlers if defined, instead of short
. widgetcontainer: woc and wiw-list
. better megawidgets
. editor: handle semicolons (need to revisit resolution rules)
. editor: break editorhook into separate properties, add them in single mode
. find a way for "package require" to work out-of-the-box on windows
* tow: canvas-wide and type-on-canvas-wide broadcasting
* plustot:
. do not evaluate if fresh, unless explicitly forced to (are side-effects
to be modal, requested with a flag, or triggered with a message?)
. pull inputs
DONE for toxy
alpha19
* plustot
. rules for slot creation:
- there is always at least one slot, although it may be deaf
- if a command contains a pseudo-scalar, there is exactly one,
listening slot
- if a command contains pseudo-array elements, there are as many slots
as the highest index + 1 (but not more than 256, a sanity limit);
listening slots are created for explicitly used elements, all other
slots are deaf
- mixing pseudo-scalar and pseudo-array forms in a single command
is prohibited
- if a command does not contain pseudo-variables, there is exactly one,
deaf slot
. firing rules established for push inputs:
- firing (evaluation with output) is executed iff all listening slots
have data and a) a hot slot receives input, or b) any slot receives
an explicit firing request ('bang' message)
- $Hin and $Cin forms of pseudo-variables: each slot may be explicitly
declared hot (Hin) or cold (Cin), overriding the default rule (leftmost
slot, if listening, is hot, others are cold) observed when the plain
form, $in, is used
- $Tin form of pseudo-variables, which is a ``pure dataflow'' variant
of $Hin: a hot slot, which looses data after evaluation (all other
kinds of slots keep data after evaluation, unless explicitly 'cleared')
- 'set' message accepted in all inlets as the `cold' input
- 'bang' message accepted in all inlets as the firing trigger
. evaluation without output:
- executed iff all listening slots have data and a) an object has
just been created (creation time evaluation), or b) an object
received an explicit evaluation request ('eval' message)
- creation time evaluation suppresses all error messages, explicit
evaluation does not
. message 'clear' in any inlet clears its slot of data
. message 'clearall' in leftmost inlet clears all listening slots
. appearance: converting dot-sequences to valid Tcl for presentation
. bug fix: made unclickable in gop
alpha18
* plustot:
. adjusted to the new, stubified +bob handling
. +selectors registered as creation selectors, so that, e.g. "+in" is
a valid input form for "plustot +in" ("+tot +in" remains valid too)
. "save" callback changes every "+tot" selector to "plustot",
and every "+selector" to "plustot +selector"
. customized appearance:
- creation selector omitted if equals "plustot" or "+tot"
- text, border and i/o outline is brown, border is thicker,
inlets and outlets are lightgrey inside and taller
. mouse click interpreted as the message 'bang'
. accepting commands without arguments (beware: this is yet to be debugged)
alpha17
* widget:
. first sketch of an editor widget (bpf), introducing a basic set of rules:
- instance data kept in its own namespace
- gui sends '_data' (replaces '_value') requests to pd, specifying one
of the standard submessages: add, delete, set, get
- pd uses the new special handler for replying: @data
(for the time being, there is only an idle loop between the two sides)
. maintaining a scriptlet collection, which mirrors type and instance
handler properties (including specials: @vis, @new, @free and @data)
. lookup in the mirror for faster and more robust handling of messages
. '@ini' section and 'ini' message removed, after being unified as the
@vis special handler (use 'set @vis' message form for passing options)
. all special handlers support short definitions (inside #. comments)
and long definitions (tagged with #@ comments), however only short
ones may be overriden by instance definitions
. long message handlers are stored, but not used yet
. .wid file header may include requirements (base widget definitions)
. fixed: patch's directory handling in 'redefine'
alpha16
* widget:
. editor for options, handlers and arguments made more or less functional
. better 'redefine' (although still only external types may be redefined)
* tow:
. fixed handling of gop-ed targets and missing windows
. new messages: 'retarget', 'pwd'
* tot:
. scriptlet editor improved a little bit (still unfinished)
alpha15
* fixes for megawidgets
. setting sub-item bindings in ::toxy::subwidget
(to be called explicitly from type initializer)
. handling widget's state through virtual events
. getting implicit geometry (needed for Frame widgets)
. automatically rebinding focus for Canvas widgets
alpha14
* 'redefine' message to widget
* version control, using package provide (both in tcl and parsed from pd)
* "> master" section removed: master initializer defined directly
by proc ::toxy::master
* better kb: chords (shift-click), latch (control-click), dragging
alpha13
* @new and @free handlers, defined in #@ new and #@ free sections,
invoked by widget object creation and destruction
* optional sections #@ ini (aka #@ vis) appended to initializer (which still
defines in default section too -- old .wid files do not need updating)
* .#args parameter of message handlers, replaced (during scriptlet
evaluation) by all arguments of an invoking message
