gnocl::label new options

Just added two new options to the label widget, -mnemonicText and -mnemonicWidget. Whilst these titles are straight from the GtkWidget api, perhaps they need renaming before adding to the distribution. Basically, these options allow fields to be accessed using quick keyboard routes. Something that has been lacking to date. Here's the script that I'm experimenting with:

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

package require Gnocl


proc labelEntry {str var} {
    upvar $var v
    set box [gnocl::box]
    set ent [gnocl::entry -sizeGroup a]
    set lab [gnocl::label -align right -widthGroup aa -mnemonicText $str -mnemonicWidget $ent]
    $box add $lab
    $box add $ent
    return $box
}

set str(1) PRAJNA
set str(2) KARUNA
set str(3) MAITRI

set box [gnocl::box -orientation vertical]

$box add [labelEntry _Prajna str(1)]
$box add [labelEntry _Karuna str(2)]
$box add [labelEntry _Maitri str(3)]

gnocl::window -child $box -setSize 0.125


And, the screenshot:

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...
