gnocl::text now supports pango markup

Spent some time today looking at how to implement the rendering Pango markup strings in the gnocl::text widget. Found a module in the StarDict app that was exactly what was needed! It took a couple of minutes to added it to the gnocl sources, modify the makefile text.c module.

Screenshot:




Test script.

# test-text-pango.tcl
#!/bin/sh
#\
exec tclsh "$0" "$@"

package require Gnocl

set pango_string(0)  {%<<span foreground="blue">Hello</span> <span foreground="red">World</span>}
set pango_string(1)  {<span foreground="blue">Hello</span> <span foreground="red">World</span>}
set pango_string(2)  {%<<span foreground="blue">Hello</span> <span foreground="red">World</span>}

set txt [gnocl::text]
gnocl::window -child $txt -width 600 -height 150

# the string is parse, and the leading %< stripped
$txt insert end $pango_string(0)\n
$txt insert end $pango_string(1)\n
$txt insert end $pango_string(2)

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 icons from UTF-8 Characters.

Linux distros have heaps of pre-installed icons ready for use. I recently needed to create a toolbar menu which needed to access a set of unique icons which contained single characters. It was, in fact, a pull down menu for the insertion of 'special characters'. The Gtk+ api has complete functionality for creating icons from pixbufs and Gnocl providing convenient access.  Here's a screenshot and the script.     # !/bin/sh # the next line restarts using tclsh \ exec tclsh "$0" "$@" package require Gnocl if { [namespace exists jmls] == 0} {     namespace eval jmls {} } set ::app(specialCharacters)  [list Section ¶ Paragraph § Separator • Left-Arrow ← Up-Arrow ↑ Right-Arrow → Down-Arrow ↓ Root √] proc jmls::charIcon {name ch} {          set pb1 [gnocl::pixBuf new -width 40 -height 40]     $pb1 text \         -position [list 15 30] \         -font [list...

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...
