bug killing! gnocl::text

Thanks to DMc for bug reports on the latest NB. Solved an issue arising from the gnocl::text search function, the interpreter would crash if the -tags option was not passed. This is now sorted and works well. The updated source and 32Bit linux builds are now available from SF.

Here's a test script.

#!/bin/sh
# the next line restarts using tclsh \
exec tclsh "$0" "$@"

package require Gnocl

set box(1) [gnocl::box -orientation vertical]

set find [gnocl::entry]
$find configure \
    -primaryIcon "%#Clear" \
    -secondaryIcon "%#Find" \
    -variable findString \
    -onIconPress {
        switch %p {
            primary {
                set findString ""
                $txt tag delete tag_find
                }
            secondary {
                $txt tag delete tag_find
                $txt tag create tag_find -foreground red
                $txt search $findString -tags tag_find
                }
            }
        }

set txt [gnocl::text -wrapMode word]
$txt lorem

$box(1) add $find -fill {1 0}
$box(1) add $txt -fill {1 1} -expand 1
gnocl::window -child $box(1)

gnocl::calendar

Given this module some attention today. Added some of the more package wide options to the module and created customised handler for setting the month. (For some odd reason months are are counted 0-11 whereas days are 1-31.) There's still a little more to do to this one including the addition of code to store diary details. Here's the working test script to show the range of options at work. The percentage substitution string item %e explores something that I've been toying with, the name of the signal/event that initiated the call. Ok, a script can keep its own internal trace but who knows, it might prove useful. #--------------- # calendarTest.tcl #--------------- # Author:   William J Giddings # Date:     07/05/09 #--------------- #!/bin/sh # the next line restarts using tclsh \ exec tclsh "$0" "$@" #--------------- package require Gnocl set cal [gnocl::calendar] $cal configure -day 8 -month 7 -year 1956 $cal configure -rowHeight 1 -colWidth 1 $ca

Gnocl Dashboard

Over the past few programming sessions I've been working on producing a central point, a dashboard, around which it's possible to see the various Gnocl widgets and commands in operation. In many ways like the demo script which shipped with the earlier releases of Gnocl but offers much more. The introspection functionality provides details of the various options and sub-commands of each Gnocl procedure which are displayed under the associated tab. Sample scripts are included for each item which offers newcomers a clearer insight into how make the most of what's on offer.

Changing Namespaces

I've been toying with the idea of changing the namespace used by gnocl, to something simplier, a proposition much more appealing now that I've begun migration to Gtk3 and soon to Gtk4. The changes from Gtk2 to Gtk4 will be subtantial due to many chages occuring within the Gtk api. Before committing myself, I thought how it would be useful to swap namespaces on the fly. So, here's a first quick solution:   package require -exact Gnocl 0.9.96 proc xxxx {ns1 ns2}  {     namespace eval ::${ns2} {}     set map [list $ns1 $ns2]          foreach type {commands vars procs } {         foreach item [info $type ${ns1}::*] {             set err ""             catch { rename $item [string map $map $item] } err             if { $err != "" } { puts $err }         }     }          namespace delete $ns1 } xxxx g set b1 [g::button -text BUTTON] set w1 [g::window -child $b1] set l1 [g::label -text rename] $w1 configure -child $l1 -title TEST
