GtkComboBox and Libglade
Hello, Is there a way to have a default value automatically selected in a combobox created with libglade ? thanks, Olivier. ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

This is all working nicely. What I'd like to do is have auto-completion available when editing the text cells, with a GtkEntryCompletion, but I can't figure out how to add one. The most likely way would be to get a pointer to the GtkCellRendererText's GtkEntry, but I can't find a way to do that. I also can't find any gtk_cell_renderer_text_* methods for adding a GtkEntryCompletion, or an object equivalent to a GtkEntryCompletion for use on GtkCellRendererTexts. If it's not too late, I'd suggest trying first to code your own cell renderer based on the GtkCellRendererText (add a property to specify the completion), and when it works, propose it as an evolution in bugzilla.

is there a g_option_print_usage() command?
I see that goption can uatomagically handle --help and the like. I'd like to emit a usage string when someone gives a bogus option - is there a call one can make to just print the same stuff that goption does on its own with --help, or do I have to mess about with error hooks? http://developer.gnome.org/doc/API/2.0/glib/glib-Commandline-option-parser.html didn't mention one - before I use something I find from source I'd want to check that it was simply an oversight in the api docs :) thanks, rick jones ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
displaying 2 images
hi...am using gtk+ on windows and am using visual c++ as compiler..in fact am
new to gtk+ programming and am having a difficulty in displaying 2 different
images by selecting a single item from combobox...when i displayed for one
image it works but to display another image for the same selected item
doesnt work...can anyone help me please?
here is the code that am using for the combobox signal:
void
on_cbo_pickobject_changed (GtkComboBox *combobox,
gpointer user_data)
{
gchar *mystr;
mystr = gtk_combo_box_get_active_text (combobox);
if (strcmp (mystr, Chair 1) == 0)
{
/*this will display the first image(Chair 1.jpg) in the
img_objectpreview when Chair 1is selected from the
combobox***/
GtkWidget *myimage_object = lookup_widget(GTK_WIDGET(combobox),
img_objectpreview); gtk_image_set_from_file
(GTK_IMAGE(myimage_object), Pictures/Chair 1.jpg);
/*i added this piece of code for a second image(Chair 1.gif) to be
displayed in img_patternpreview/
GtkWidget *myimage_pattern = lookup_widget(GTK_WIDGET(combobox),
img_patternpreview); gtk_image_set_from_file
(GTK_IMAGE(myimage_pattern), Pictures/Chair 1.gif);
}
else
{
.../* show default image */
}
g_free (mystr);
}
here is the error i got when compiled:
callbacks.c(162) : error C2275: 'GtkWidget' : illegal use of this type as an
expression
callbacks.c(162) : error C2065: 'myimage_pattern' : undeclared identifier
can someone please help me? what is missing in the code above? can someone
add the missing code for me please?? how will it work? please help..
i would be much grateful if someone can help me please..
thanks

...because this makes very hard to find where one statement

the end of one statement and the start of another, how you
can hope to find bugs there (or ask others to find them for

Also either include the complete file or note which line is
the one referenced in the error message (162 here). Without
that it is impossible to tell not only which line of the
snippet is 162 but also whether the included code contains
line 162 at all.
Now, the problem is -- probably, as no one knows what is
actually on line 162 -- still the same it was five days ago
when you asked the first time: You cannot mix declarations
and code in C. This is mixed:
declaration- GtkWidget *myimage_object = ...
code - gtk_image_set_from_file(...
declaration- GtkWidget *myimage_pattern = ...
code - gtk_image_set_from_file(...
This is in the proper order declaration(s), then code:
declaration- GtkWidget *myimage;
code - myimage = lookup_widget(...
code - gtk_image_set_from_file(...
code - myimage = lookup_widget(...
code - gtk_image_set_from_file(...

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.

Pango-1.16.1 released
Pango-1.16.1 is now available for download at: http://download.gnome.org/sources/pango/1.16/ 4aa720633e53701a652f27700a7946dd pango-1.16.1.tar.bz2 8002b54b956e1194a6145a765a267638 pango-1.16.1.tar.gz This is a stable release and is source and binary compatible with 1.16.0. About Pango === Pango is a library for layout and rendering of text, with an emphasis on internationalization. Pango can be used anywhere that text layout is needed, though most of the work on Pango so far has been done in the context of the GTK+ widget toolkit. Pango forms the core of text and font handling for GTK+-2.x. Pango is designed to be modular; the core Pango layout engine can be used with different font backends. There are three basic backends, with multiple options for rendering with each. - Client side fonts using the FreeType and fontconfig libraries. Rendering can be with with Cairo or Xft libraries, or directly to an in-memory buffer with no additional libraries. - Native fonts on Microsoft Windows using Uniscribe for complex-text handling. Rendering can be done via Cairo or directly using the native Win32 API. - Native fonts on MacOS X, rendering via Cairo. The integration of Pango with Cairo (http://cairographics.org) provides a complete solution with high quality text handling and graphics rendering. Dynamically loaded modules then handle text layout for particular combinations of script and font backend. Pango ships with a wide selection of modules, including modules for Hebrew, Arabic, Hangul, Thai, and a number of Indic scripts. Virtually all of the world's major scripts are supported. As well as the low level layout rendering routines, Pango includes PangoLayout, a high level driver for laying out entire blocks of text, and routines to assist in editing internationalized text. More information about Pango is available from http://www.pango.org/. Bugs should be reported to http://bugzilla.gnome.org. Pango 1.16 depends on version 2.12.0 or newer of the GLib library and version 1.2.6 or newer of the cairo library (if the cairo backend is desired); more information about GLib and cairo can be found at http://www.gtk.org/ and http://cairographics.org/ respectively. Overview of changes between 1.16.0 and 1.16.1 == - Improved Win32 backend: The Win32 backend has been updated to always require Uniscribe at compile-time (it still is optional at run-time), and to use the wide-character variants of Windows APIs which improves the backend in many ways. The 1.16.0 release is obsolete as far as the Win32 backend is concerned, and official DLLs were not built for it. - Misc build system fixes - Bugs fixed in this release: Bug 110521 – can't find bold and/or italic fonts on win32 Bug 120195 – there are some functions in pangowin32-fontmap.c that might maybe should be static Bug 407315 – Use wide character Win32 API in the pangowin32 code Bug 412654 – SED variable undefined in the `libtool --config' output used by configure Bug 414297 – Fails to build with --enable-static --with-included-modules in thai lang module Patch from Loïc Minier 12 March 2007 Behdad Esfahbod ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
