* ext/tk/*: Support new features of Tcl/Tk8.6b1 and minor bug fixes.
( [KNOWN BUG] Ruby/Tk on Ruby 1.9 will not work on Cygwin. )
* ext/tk/*: Unify sources between Ruby 1.8 & 1.9.
Improve default_widget_set handling.
* ext/tk/*: Multi-TkInterpreter (multi-tk.rb) works on Ruby 1.8 & 1.9.
( [KNOWN BUG] On Ruby 1.8, join to a long term Thread on Tk
callbacks may freeze. On Ruby 1.9, cannot create a second
master interpreter (creating slaves are OK); supported master
interpreter is the default master interpreter only. )
* ext/tk/lib/tkextlib/*: Update supported versions of Tk extensions.

Three different combo-boxes are displayed below. \
|
|
You can add characters to the first \
|
|
one by pointing, clicking and typing, just as with an entry; pressing \
|
|
Return will cause the current value to be added to the list that is \
|
|
selectable from the drop-down list, and you can choose other values \
|
|
by pressing the Down key, using the arrow keys to pick another one, \
|
|
and pressing Return again. The second combo-box is fixed to a \
|
|
particular value, and cannot be modified at all. The third one only \
|
|
allows you to select values from its drop-down list of Australian \
|
|
cities.
