Coding and Documenting...

I've got half a morning free today so I've decided to spend an hour or
two working on the gnocl::pixBuf module. This morning I decided not to
let the process of creating working documentation slip by. Ok, I've got
the source code fully annotated and marked up for documentation with
doxygen but that's gnocl package development and not applications
development documentation. In the past I looked at creating appdev docs
alongside within doxygen, I guess that it's possible to do but is too much of a
headache!As I always have Firefox open when I'm coding to use the Gtk/Gnocl
online docs, I've decided to keep a page open on Google Applications
Documents to create the pages for the programmers docs. Lets hope this
strategy works well.

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.

Creating a button box with right aligned widgets

The dialog widget has its own internal functionaluty to create and position buttons at the bottom right corner of the window container. When creating these for ourselves it must be born in mind that default settings for fill and expand are both 0.5. Failing to set these will always place the child objects in the centre, regardless of alignment. For most cases these defaults are acceptable but, to create that dialog-button arrangement, use the following snippet as a model! # to right align completely, set expand and fill to 0 set hbox [gnocl::hBox] set b1 [gnocl::button -text Select \ -data $lst -onClicked { puts DO-SOMETHING-WITH-%d} ] set b2 [gnocl::button -text Cancel -onClicked { puts DONE! } ] $vbox add $hbox -expand 0 -fill 0 -align right $hbox add $b1 $hbox add $b2
