1 =======================================================================
2 Following is a list of notes describing things which might be
3 fixed or changed in a future release of [incr Tcl]
4 =======================================================================
6 Handle this case more elegantly:
22 ------------------------------------------------------------------
23 - add virtual inheritance
24 - add "border" type to canvas widget
25 - add "validate" and "valid" commands for type validation
26 - add "unknownvar" and provide access to object data members: "obj.var"
27 - check namespace [info class] {...} as a replacement for "virtual"
28 - fix "auto_load_all" problem in Tcl-DP
29 (Their implementation uses "info commands" to verify that a command
30 has been successfully autoloaded, but absolute command names like
31 "::iwidgets::fileselectiondialog" don't show up.)
32 - fix "auto_load" mechanism to be extensible like "unknown"
33 - fix Itcl_RegisterC() to support ClientData
34 - core dump with "cmdtrace" (tclX thing?)
36 - ideas from Nelson Macy:
37 - add "delegate" keyword for inheritance via composition?
38 - add "forward" keyword for implementing error handlers
39 - add "get" code to public variables for "cget" access
41 - equivalent of constructor/destructor for classes
42 - protected/private recognized for constructor/destructor
43 - add something like Tk_CreateWidgetCommand() for widget developers
46 itcl documentation cleanup
47 ------------------------------------------------------------------
48 - add "Finance: Trading Systems" to commercial uses of Itcl (Deshaw)
49 - update doc: "config" code also gets invoked on startup for itk widgets
50 - update doc: add to FAQ: class with common array interacts with Tk widget
53 ------------------------------------------------------------------
55 - write "auto_load_all" proc for Tcl-DP
58 > More specifically, the constructor for the class did the following:
60 > set hull [info namespace tail $this]
63 > One of the class variables had a configuration script:
65 > public variable textvariable "" {
66 > if { $textvariable != "" } {
67 > regsub "\\(.*\\)" $textvariable "" global
69 > trace variable $textvariable w "$hull adjust"
73 - add "@body" in as many places as possible to support Tcl compiler
75 - check out itcl with Tix:
76 lappend auto_path $env(TIX_LIBRARY)
77 source "$env(IWIDGETS_LIBRARY)/init.iwidgets"
79 iwidgets::Dialog ._Arcattributes -title "Code: Arc Annotations"
82 set attrframe [._Arcattributes childsite]
84 tixScrolledHList $attrframe.ports
85 [$attrframe.ports subwidget hlist] configure -selectmode browse
87 pack $attrframe.ports -expand yes -fill both -padx 10 -pady 10
89 ._Arcattributes activate
