Array of arrays

Hi,
First of all it would be helpful if you told us what is the problem with
your code, off the bat I could tell you that the way you pass a pointer
to an array of pointers is foreign to me, I think I would have just used
GArray ***arrays_p; for that argument.
But on the other hand, you could just save yourself that headache and
use a GPtrArray of GArrays (you could even get carried away and whip
up an api that updates the values of ptrarray-pdata[i] = garray-data
and have a real indexable array in C...).
Cheers,
-Tristan

PangoF2 in win32 not applying GSUB.
Hello, I have been debugging this issue for the last few days and found that when using pango (pango-1.26.2) with ft2 backend, GSUBs are not being applied (in telugu using lohit_telugu font). I traced this to harfbuzz. When I use an older version of pango (pango-1.12.4) where harfbuzz is not being used, gsub works without any issues. I saw a similar issue mentioned for Arabic font where pango-cairo was working and pango-ft2 was not. http://www.mail-archive.com/gtk-i18n-list@gnome.org/msg01565.html I tried with cairo backend and it worked since cairo was using Uniscribe. When I forced cairo to use FT2 backend, I got back the same results of gsub not being applied. pango-1.26.2 works without any issues in linux so I compared the two using gdb and I noticed that in win32,in function indic_engine_shape, ruleset-rules-len was returning 0, but in linux it was returning valid value of 7. I traced this in hb_ot_layout_table_find_script and found that find_script_index was returning error for telugu script. You can reproduce this with the attached source file. You will notice that when using pango-1.12.4 you will get one glyph (correct) but when using pango-1.26.2 you will get two glyphs. I am using MinGW and Msys to compile just pango, I am using binary packages from GTK site for other packages. I am using the following command for compiling. g++ gTestPango.cpp `pkg-config.exe pangoft2 --cflags --libs` ./a.exe all.txt gcc gtestcairo.c `pkg-config.exe pangocairo --cflags --libs` ./a.exe test.png This is the command I am using for compiling pango. ./configure --with-included-modules --prefix=/mingw make make install Warm Regds, Ravi Kiran. gtestcairo.c Description: Binary data gTestPango.cpp Description: Binary data ___ gtk-i18n-list mailing list gtk-i18n-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-i18n-list
Re: [gnome-db] Include Gir file with constant #x1b;[;31;1m

I am doing my best to have Libgda 4.0.7 included in upcoming Ubuntu Lucid (which is Long Term Supported release). To make this happen I requested Libgda updates in Debian unstable (which migrated to testing release already). If GIR support could be ported to 4.0 branch and 4.0.8 could be released in reasonable short time, there is a chance many people could be happy with stable and easy available Libgda for long time. GIR support has been added to the LIBGDA_4.0 branch, but I haven't tested it at all (though it's the same as for the master branch and it works fine), so some minimal testing should be done here.

Issues with performance of Simple List
I am having issues with the performance of simple list in a wierd way
Basicaly I have a simple list object embedded into a window which gets
data from a sqlite database via user defined criteria
If I dont access the simplelist at all changes to the data are nearly
instantaeous however if access the simple list at all there is a delay
between 20-40 seconds
this is the table creation code
any tips appreciated
