Basic Differences
Hi Is there any basic difference between GTK+, Qt and Motif? Is gtk+ advantageous over others? I just heard of these tools for developing GUIs. Is there any other tools also used for this purpose? Can gtk+ be used in KDE environment also? GNOME and KDE are 2 desktop environments of Linux platform, right. Is there any particular difference between GNOME and KDE? Can this be used in Windows? If no, then why is told that gtk+ can be used in Windows also.. Will it be better to use Glade to design the GUI's in Fedora, actually our platform is OLPC? Or is there any other GUI builder which is better than Glade? Could anyone suggest the better one… Can we compile an application built using gtk+ in C using the sdcc compiler? Because we need to execute and run as the user changes the settings in the interface. So in OLPC there is only sdcc. We don't know whether we can install the gcc compiler or not. So will it create any problem. Waiting for the much needed answers. aswathy ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
GTK+ 2.12.9 released
GTK+ 2.12.9 is now available for download at: http://download.gnome.org/sources/gtk+/2.12/ gtk+-2.12.9.tar.bz2 md5sum: 33499772fdc3bea569c6d5673e5831b4 gtk+-2.12.9.tar.gzmd5sum: dce06e3ea184208e3c9a60eb78c29894 This is a bug fix release in the 2.12 series. What is GTK+ GTK+ is a multi-platform toolkit for creating graphical user interfaces. Offering a complete set of widgets, GTK+ is suitable for projects ranging from small one-off tools to complete application suites. GTK+ has been designed from the ground up to support a range of languages, not only C/C++. Using GTK+ from languages such as Perl and Python (especially in combination with the Glade GUI builder) provides an effective method of rapid application development. GTK+ is free software and part of the GNU Project. However, the licensing terms for GTK+, the GNU LGPL, allow it to be used by all developers, including those developing proprietary software, without any license fees or royalties. Where to get more information about GTK+ Information about GTK+ including links to documentation can be found at: http://www.gtk.org/ An installation guide for GTK+ 2.x is found at: http://developer.gnome.org/doc/API/2.0/gtk/gtk-building.html Common questions: http://developer.gnome.org/doc/API/2.0/gtk/gtk-question-index.html http://www.gtk.org/faq/ Contributing GTK+ is a large project and relies on voluntary contributions.

Please, consider some rewirtting of your application to do not write locale-dependent values (floating point numbers, month abbrevs, day-of-week abbrevs, and so on...) in the data files, or your files will become unreadable after changing of locale (and, if I understand correctly, you already hit this problem).

See g_ascii_dtostr() and/or g_ascii_formatd() for formatting/serialization of double to string, and g_ascii_strtod() and/or g_strtod() converting back from string to double. Maybe you can use some char based format as DECIMAL in mysql. DECIMAL[(M[,D])] [UNSIGNED] [ZEROFILL] For MySQL 5.0.3 and above: A packed “exact” fixed-point number. M is the total number of digits (the precision) and D is the number of digits after the decimal point (the scale). The decimal point and (for negative numbers) the ‘-’ sign are not counted in M. If D is 0, values have no decimal point or fractional part. The maximum number of digits (M) for DECIMAL is 65 (64 from 5.0.3 to 5.0.5). The maximum number of supported decimals (D) is 30. If D is omitted, the default is 0. If M is omitted, the default is 10. UNSIGNED, if specified, disallows negative values. All basic calculations (+, -, *, /) with DECIMAL columns are done with a precision of 65 digits. so for example 123456,01 if you use as standard value DECIMAL(10,2) would be 12345601. This value could then be converted at runtime when imported to the correct decimal separator. val = atoi(1234501) / 100; Just an idea, Tito PS: sorry for the double post ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

Use some locale-independent variant instead. For case of the floating point values it could be dot-based variant as in the C locale. Fortunately the only locale dependent values I have issues with are decimal numbers. If I follow Martin's suggestion, inserting gtk_disable_setlocale () before gtk_init (), everything is consistent and works fine, XML importing/exporting, GTK interfaces, etc. I just tested it. Unfortunately this means always using dot-based decimals. I always use dots myself, so this is not an issue for me. But I understand that other people might wish to use commas instead. I think the ideal solution is: when importing files, accept both dots and commas, so for example this XML line should be acceptable: element x=1.0 y=2,0/ Then do all the work in the locale chosen decimal separator. So a US user would work and export with dots, send the file to his french friend, who reads the dots and then works with commas, export with commas, send the file back to the US user who reads the commas without problems. In fact I suspect this is how programs tend to work these days (I tested Origin, I believe Excell does this also, etc.). Unfortunately it also means that comma cannot be easily used as a separator in txt files. I tried to read a file test.txt with only this line inside: 1.0 2,0 Gnumeric thinks the comma is a separator. OOCalc asks for a separator, and after chosing space separators reads 1.0 and 2,0 in two different cells, but changing the number of decimal figures works only for 1.0 ... Even if I use: 1,0 2,0 with LC_ALL set to french, gnumeric still ignores the commas and reads this as 1 followed by 02 followed by 0 ...

app/window deactivation handling
Hello, In an app we are working on we have some things that need to be done when the app (or window since we only have one main window) is deactivated. That is when the use switches to another application we want to get control to clean somethings up before being deactivated. Any pointers on where to hook into this? thanks, steve ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
