New button options -orientation, -invert

The default settings for the gnocl::button are for the icon to be on the left and the label on the right. Not all  buttons need to be like this. Consider the toolbar button where the icon in above the label. These new options offer the programmer a little more flexibility when building a UI using Gnocl, especially when creating ribbon type containers.

This is how the new settings look:











 And the sample code:


set hbox [gnocl::hBox]
   
set but1 [gnocl::button -text vertical -icon %#Info -data DATA -orientation vertical ]
set but2 [gnocl::button -text vertical-invert -icon %#Info -data DATA -orientation vertical -invert 1]
set but3 [gnocl::button -text horizontal -icon %#Info -data DATA ]
set but4 [gnocl::button -text horizontal-invert -icon %#Info -data DATA -invert 1]
   
puts "but1 orientation = [$but1 cget -orientation]"
puts "but3 orientation = [$but3 cget -orientation]"

puts "but1 invert = [$but1 cget -invert]"
puts "but2 invert = [$but2 cget -invert]"

$hbox add $but1 -fill 1 -expand 1
$hbox add $but2 -fill 1 -expand 1
$hbox add $but3 -fill 1 -expand 1
$hbox add $but4 -fill 1 -expand 1
   
gnocl::window -child $hbox -title "Button -invert and -orientation"

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.

Getting Widget Style Properties

Until the move over to Gtk4, Gnocl is still built against the Gtk 2.21 libraries. One of the inconveniences of Gtk is getting and setting widget style settings which are considered to be set globally by the desktop style settings and not for the programmer to tinker around with. Needless to say, there are times when different defaults are preferred, largely to draw the users attention to 'something a bit different'. The function gtk_widget_modify_font  is a convenience function to set the widget basefont as shown in this snippet from the button.c module,  if ( options[baseFontIdx].status == GNOCL_STATUS_CHANGED ) { GtkWidget *label; label = gnoclFindChild ( GTK_WIDGET ( para->button ), GTK_TYPE_LABEL ); PangoFontDescription *font_desc = pango_font_description_from_string ( Tcl_GetString ( options[baseFontIdx].val.obj ) ); gtk_widget_modify_font ( GTK_WIDGET ( label ), font_desc ); pango_font_description_free ( font_desc ); } Unfortunately, there's no d...
