GnoclSpellCheck

The earlier version of the GnoclSpellCheck module as developed on my ancient 32-bit workstation running OpenSuse 11.2 (yes, I said that it was ancient). The problem arising from using legacy equipment is that when packages like Gnocl are developed, not only can various elements cease to work (i.e GtkSpell 2 does not run at all on a Gnome 3 desktop or under Ubuntu Mate) but later libraries such as GtkSpell 3 are complete re-writes and can, as I've found, have their own bugs! A new Gnome speller, gspell is under development but this requires the bleeding edge Gtk3 libraries which, apart from being incompatible with the Gtk+2 libraries against which Gnocl is built, these latest versions are not currently part of the stable releases. So, I thought, build my own. So, I did. Rather than using the C-api for either Ispell, Aspell or Hunspell, I've just used a simple data pipe. These three packages give varying suggestions for misspelt words so, the eventual front end will enable the user to pick which engine they want to use.

Here's a screen shot of the development program.  All the key elements are present: check as you type, errors are marked up, popup menus contain alternatives.  Just a little tweaking needed (if possible) to offset the error underline as the window manager doesn't seem to adequately refresh to layout to remove artefacts.


















Currently working on a GUI for the full checker based upon the LibreOffice model.

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...
