The recently added 'tabCondfigure' and 'tabCget' is now replaced with 'tab configure' and 'tab cget'.

I've just been working on the module to create the gnocl notebook widget, paying particular attention to the tab configuration options.
 

Earlier, and for convenience's sake, I added two commands tabConfigure and tagCget. All well and good, but the established practice of is to have the commands addressing the main container, and sub commands container objects, in the manner of the text and its tags and various other elements.
 

The reasoning for this is that the notebook tab contains a child widget, a label by default, which the Gtk api allows to be directly accessed or even replaced. This is how some applications are able to embed widgets into notebook tabs (take Geany for example).
 

Unlike text tags, which are the same class of object, the notebook tab ans a container can  become the parent of any other widget or even a boxed set of widgets. Aware of this, any specific cget or configure command needs to be customized in order to allow for this extra flexibility.  

To accommodate this the notebook source module contains two functions tabConfigure and tabCget to handle these differences. 

The creating the tabConfigure function was pretty straight forward, but getting the tabCget function just right was a little more elusive, perhaps largely due to the side effects of having just had a covid jab!

Determining which of the options is queried in the source is achieved with a simple while () loop through each element in the tabOptions structure array:


     while ( tabOptions[idx].optName != NULL ) {

        if ( strcmp ( tabOptions[idx].optName, Tcl_GetString ( objv[4] ) ) == 0 ) {
            break;
        }
        idx++;
    };


    
The resultant value for idx is then passed through a switch filter and the appropriate values retrieved.

The practical benefits of the tab configure option are the settings controlling the tear-off and relocation of tabs in the tab bar can be adjusted, menu labels and texts can be reset, and of course, multiple items embedded into the tab.

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

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

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.
