Tim Wallace — Tue, 24 Jul 2012 15:14:15 -0000

Make scrolledtext search method work with patterns containing spaces.

using ttk scrollbars in iwidgets

Sean Morrison — Wed, 23 Mar 2011 23:15:15 -0000

The included patch replaces iwidgets scrollbars with the newer ttk:: scrollbars. Code simplified and behavior is improved (scrollbars now seamlessly integrate with windows using non iwidgets (i.e., ttk) scrollbars.

If the patch is accepted, credit goes to Cliff Yapp and Bob Parker.

Cheers!

patch for datefield with 8.5

Mark Alston — Sat, 20 Sep 2008 03:24:03 -0000

This patch fixes datefield with -iq high to be compatible with tcl8.5.

Problem:
Turns out that clock scan never returns an error in 8.5 but will just give you returns for the next month. Very bad in my opinion.

The Fix:
Replace the _lastDay portion of datefield.itk with the following which checks to see if the month has changed if the clock scan returns ok.

# ------------------------------------------------------------------
itcl::body iwidgets::Datefield::_lastDay {month year} {
# Patched to work with Tcl 8.5
set lastone 28

for {set lastone 28} {$lastone < 32} {incr lastone} {
set nextone [expr $lastone + 1]
if {[catch {clock scan $month/$nextone/$year} newdate] != 0} {
return $lastone
} else {
set datestring [clock format $newdate -format "%m/%d/%Y"]
set splist [split $datestring "/"]
if { [lindex $splist 0] != $month } {
return $lastone
}
}
}
}

Best regards,

Multiple tiers for tabset/tabnotebook

Erik Allaert — Wed, 28 Mar 2007 11:49:14 -0000

these are modified versions of tabset.itk and tabnotebook.itk (diff-files attached) which implement a multiple tier feature. It is used in the tabnotebook via the new "-tiers" option:
# OPTION -tiers
#
# Specifies the maximum number of tiers for the tabs.
# If set to 0, then there will be only 1 tier, without any expansion (default).
# If set to > 0, the highest tier number will have all its tabs adjusted

# so they occupy all the space of this tier.
# If set to < 0, the highest tier number will not have its tabs adjusted - really for experimentation only

Same as "feature request" #643765.

Please note that the attached patches also deal with tickets #620806 and #514222

AND: INTENDED PRIMARILY FOR DEMO-PURPOSES, i.e. using multiple tiers is a bad idea - see http://homepage.mac.com/bradster/iarchitect/tabs.htm
(On that page, Laura Arlov is quoted from her book "GUI Design for Dummies": "One row of tabs is enough. Again: One row is enough. And once more: One row is enough.")

Iwidgets configure/install patch

James Bonfield — Fri, 08 Jul 2005 10:25:24 -0000

The iwidgets4.0.1 package has a configure system that
dates back to when itcl and itk were in the same
directory. It doesn't work with 3.3RC and apparently
not 3.2 either.

The following patch was tried with the 3.3RC
distributions. The key changes are:

1. Look for itcl/itk in the parent directory of
iwidgets (ie they should be siblings). --with-itcl /
--with-itk overrides this.

2. Use AC_PROG_INSTALL and include an install-sh script.

3. Replaced MKINSTALLDIRS with mkdir -p. This seems to
be what itcl3.3 uses now so it's hopefully no less
portable than that is.

I haven't tried this on cygwin so I've no idea if the
cygpath stuff still works or not.

DateField, Dateentry with DD/MM/YYYY

Cedirc Shock — Tue, 19 Aug 2003 23:51:57 -0000

I have added a DD/MM/YYYY "Aussie" mode to the
dateentry and datefield widgets. To use it create the
widgets with the option:

-int au

(AU is for australia. -int 1 will use YYYY-MM-DD mode,
and -int 0 will use MM/DD/YYYY.)

Attached is the file datefield.itk
Place it in your IWidgets script directory.

I have not tested it with versions prior to 4.2.

Enjoy :)

4.0.1 dateentry patch for popup calendar

Mark Alston — Tue, 03 Sep 2002 04:03:14 -0000

This is a fix to my previous patch of dateentry. My
previous patches added the -int option to datefield,
dateentry and calendar however dateentry didn't pass
the option onto the popup calendar which causes a
major problem.

I have also added a catch for bad dates when using the
popup calendar. Since we allow people to use -int low
we should still allow the use of the calendar popup.
Thus, now when a date in the entryfield is bad the popup
window shows the current date instead of crashing.

datefield patched for USA and European

Steve Burger — Wed, 03 Jul 2002 07:44:55 -0000

Widget: Datefield 4.0.0

Constructor checks for environment variable
TCLDATEFORMAT, if set to European dates are in
dd/mm/yy format else set USA format.

get method still returns mm/dd/yy, added -european option
to get dd/mm/yy not tested.

Show still expects date in mm/dd/yy. Have added a -e|-
european option to allow inout of euro date but not tested.

Fixed bug with _lastDay method so that -iq HIGH works.

Shift tab and Ctrl tab act as back tab.

Works with Dateentry

Spanish datefield

Hugo Javier Curti — Wed, 13 Feb 2002 18:47:38 -0000

This patch permits dates to be shown and entered in Spanish format (dd/mm/YYYY). The result of the get command returns the original format (mm/dd/YYYY) to maintain compatibility.

The Tab Key binding was also modified so it behaves as in any other widget (transverse).

The patch was made against iwidgets4.0.0 release sources.

iwidgets tabnotebook resize loop

James Bonfield — Thu, 07 Feb 2002 12:07:01 -0000

On MacOS X with Jim Ingham's native tcl/tk the
tabnotebook gets stuck in infinite loops of
configure events.

This is possibly due to the fact that I am using tcl/tk
8.4a4 - I have not tested whether this version also
produces the same problems on other operating
systems.

The problem is simply that the frame widget now
takes -padx and -pady options which default to 0,
but are set to 4 by the options set in tabnotebook.
This causes the _resize function (tested with
iwidgets4.0.0) to loop indefinitely as the canvas is
no longer the same size as the hull.

The solution is simply to reset padx and pady:

*** tabnotebook.itk.orig Thu Feb 7 11:58:07
2002
--- tabnotebook.itk Thu Feb 7 11:58:25 2002

*** 168,174 ****
