pango or any other way to format text
Can anybody please take some time to show me simple way of implementing pango formatting to get greek letters, subscripts and superscripts in gtk2+? A minimal(complete with headers) example will be very appriciated. -- Rudra JRF; SNBNCBS http://www.bose.res.in/~rudra A bus station is where a bus stops. A train station is where a train stops.

For superscript and subscript you use sup and sub as in HTML. These are not needed for Greek accents such as rough breathing, of course.

What do you mean by ‘implementing Pango formatting'? I suppose you are not writing a Pango backend, i.e. you are not *implementing* any text rendering yourself. If you just want to use Pango to render Greek text, subscripts, superscripts, Cyrillic, math symbols or whatever, use UTF-8: GtkWidget *label = gtk_label_new(ἀπὸ τοῦ ἡλίου μετάστηθι); or GtkWidget *label = gtk_label_new(a² + b² = c²); That's it. Function gtk_label_set_markup() with Pango markup http://developer.gnome.org/pango/stable/PangoMarkupFormat.html can be used for more complex indexes and exponents and other stuff in labels.

Re: Event Mask Question
Well I have taken a different approach to my programming given how events changed. I just turn on all events and then my code will determine which event I'll inhibit or not depending on the widget I am building. Seems to be working fine, exception for key_press and key_release. Can't get these events any more. I am guessing I am going to be forced to use Cairo and I don't know where a good source for learning Cairo is.

See http://developer.gnome.org/pango/stable/PangoMarkupFormat.html for the syntax for subscripts and superscripts.

GRegex regular expression failing to match
I'm trying glib's GRegex functionality for the first time, and
apparently I am doing something wrong. I have some code like so:
code:
GError * error = NULL;
GRegex * regex = g_regex_new (^/(d+)$, 0, 0, error);
if (error != NULL)
{
// ...
}
GMatchInfo * match_info;
g_regex_match (regex, path, 0, match_info);
if (g_match_info_matches (match_info))
{
gchar * word = g_match_info_fetch (match_info, 1);
// ...
}
In my unit test, I pass in in the string /1, hoping to match and then
pull out the number. A GError is not thrown (so my GRegex is compiling),
but g_match_info_matches() is returning FALSE.
Is there anything wrong with the regexp, or perhaps my g_regex_new()
options, or anything else obvious?

It should be ^/[0-9]+$ not ^/d+$ First, it lacks the backslash to make \d a digit atom. But, second, since \d matches a digit (possibly whatever Unicode may say is a digit), not 0-9, you should really use [0-9] to match ASCII digits.

GtkTable cells resizing
Hi, I have an application with a tabbed view. On two tabs I have a table, one is a 2x2 table, the other a 3x1 table (3 rows). In each cell is a canvas that has a gtk plot. I want to be able to click one of the plots in the 3x1 table and change the canvas size to 2/3 the original, with the other two canvases being 1/6 the original size. After redrawing and resizing and mucking about, I can't get the table rows to be different sizes, accommodating the different sized canvases properly, even though I have gtk_table_set_homogeneous (table, FALSE); Any clues how to do this?

Re: GtkTable cells resizing
Are you using GTK+ 3 ? If so, use GtkGrid instead... possibly just that will fix things for you. Short of that, if I understand correctly, you have a target state/configuration of a GtkTable (or GtkGrid), if you construct the table in the target configuration from scratch, I take it things work as you want... but dont work properly after performing some kind of a transformation to reach your target state... ... perhaps it's worth trying an extra call to gtk_widget_queue_resize() after modifying your table.

Feel I've been around and around the mulberry bush on this ;-) Hard to say whats going on here, I wonder who is responding to the size requests for these items which are getting drawn. It seems you connect to a signal to draw on a widget, which means the content is not the widget, so probably you need to also connect a signal to override the size request of the said widget you intend painting onto ? Perhaps you are using forced size requests to accomplish this (using gtk_widget_set_size_request() or such), and have somehow mixed up the size requests while swapping your content onto new rows/columns ? Other than that, child 'expand' properties will be considered by the GtkTable (if all children can expand, then it's quite possible that after reaching a large window size the content will be evenly spread).
