* 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 spin-boxes are displayed below. \
|
|
You can add characters by pointing, clicking and typing. \
|
|
The normal Motif editing characters are supported, along with \
|
|
many Emacs bindings. For example, Backspace and Control-h \
|
|
delete the character to the left of the insertion cursor and \
|
|
Delete and Control-d delete the chararacter to the right of the \
|
|
insertion cursor. For values that are too large to fit in the \
|
|
window all at once, you can scan through the value by dragging \
|
|
with mouse button2 pressed. Note that the first spin-box will \
|
|
only permit you to type in integers, and the third selects from \
|
|
a list of Australian cities.
|
|
If your Tk library linked to Ruby doesn't include a 'spinbox' widget, \
|
|
this demo doesn't work. Please use later version of Tk \
|
|
which supports a 'spinbox' widget.
