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.

Hello,

i am even not getting it to run. I nearly tried each Version of Gnocl but i am always getting:

% gnocl::calendar
configure
demonstrate_details
calendar_update_details -1
calendar_update_details -2
calendar_update_details -3
calendar_get_detail -1
calendar_get_detail -2
calendar_get_detail -3
calendar_update_details -4
Segmentation fault

Where is the fault?

Hi Crisskross

Basically, the instructions which you've applied are not valid.

The segmentatation fault is arising from the interpreter trying to handle these instructions.

First of all thx for the fast reply. :)

What do you mean with not valid?

when i am trying to set t with:

set t [gnocl::calendar]

i am getting the following errors:

configure
demonstrate_details
calendar_update_details -1
calendar_update_details -2
calendar_update_details -3
calendar_get_detail -1
calendar_get_detail -2
calendar_get_detail -3
calendar_update_details -4
Segmentation fault

So what do you mean with the interpreter?

In that case I'm not sure where the problems are coming from. The test script given above still works on my machine even with the current build.

If this information is being output to the console then it looks like some the debugging comments typically generated. If this is the case, then the segmentation fault may be arising from a bad printf/g_print command in the sources.

I'll take at the sources look this evening.

Hello, did you find some errors?

I've tidied up the debug comments and so these should not interefere with your scripting.

I get no runtime errors at all.

The calendar implementation still needs a whole pile of work doing on it. Its ok, for selecting dates, but the Gtk+ widget has much more to offer, i.e data display.

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...
