how to remove the contents of vbox?

2010-04-19 Thread Arthur 1989 
hello, I got this func: static void (GtkWidget *vbox) {...}, when passed in
an vbox, it should insert a GtkWidget *scrolled_window into the vbox, but I
want to clear the contents of vbox first,otherwise the old contents will be
displayed as well as the newly inserted widget. I am wondering how to
implement this.Any tips will be appreciated.

Just call gtk_widget_destroy() on previously inserted scrolled window.

How to handle GIO channel when the other side kills the connection

2010-04-19 Thread silverburgh 
Hi,

I am using GIOChannel in my gtk application. I am able to read/write
to GIO channel with a 'client' application, my gtk application serves
as a 'server'.

But when the 'client application' dies unexpectedly, I see a lot of
these errors from my gtk application ('server') terminal:
 GLib-CRITICAL **: g_io_channel_read_chars: assertion
`channel-is_readable' failed

 GLib-CRITICAL **: g_io_channel_read_chars: assertion
`channel-is_readable' failed

 GLib-CRITICAL **: g_io_channel_read_chars: assertion
`channel-is_readable' failed

Can you please tell me what does that mean? And how can I fix it?

Thank you.

Re: Setting a Tree View Cell to insensitive and uneditable

2010-04-19 Thread Gabriele Greco 


 Is it possible to set a cell in a specific column and row to insensitive
 and uneditable and not affect the rest of the cells in the same column?


Yes, you should change your TreeModel to have two additional boolean columns
to map the sensitive and editable boolean field for your TreeViewColumn,
something like (let's get the simple case of a single editable text field):


mymodel = gtk_list_store_new(3, G_TYPE_STRING, G_TYPE_BOOLEAN,
G_TYPE_BOOLEAN);

gtk_list_store_set(mymodel, it, 0, Editable Cell, 1, TRUE, 2, TRUE, -1);
gtk_list_store_set(mymodel, it, 0, Not editable Cell, 1, TRUE, 2, FALSE,
-1);
gtk_list_store_set(mymodel, it, 0, Insensitive Cell, 1, FALSE, 2, FALSE
/*may be also true*/, -1);

gtk_tree_view_insert_column_with_attributes(mytreeview, -1,
My column title, r, markup, 0, sensitive, 1,
editable, 2,
NULL);

I've written not the full code but just the lines that should differ from
your actual implementation :)

Re: Setting a Tree View Cell to insensitive and uneditable

2010-04-19 Thread Nicolas Soubeiran 
When creating your model set a specific column with a boolean property.
e.g :
enum
{
STRING_COLUMN =0,
EDITABLE_COLUMN,
N_COLUMN
}
...
 gtk_list_store_new(N_COLUMN, G_TYPE_STRING, G_TYPE_BOOLEAN);

Then in the treeview create a column using
gtk_tree_view_column_new_with_attributes(title, text_cell,string,
STRING_COLUMN, editable, EDITABLE_COLUMN, NULL);

and when fillling your model precise which row is editable.
Hope this help,
regards

GLib 2.25.0 released

2010-04-19 Thread Matthias Clasen 
GLib 2.25.0 is now available for download at:

  ftp://ftp.gtk.org/pub/glib/2.25/
  http://download.gnome.org/sources/glib/2.25/

sha256 sums:
3815e6c0053e488fdbde032de133d7218953c7c9a1b11839dbb828db6ba023c3
glib-2.25.0.tar.bz2
6c54ec9d941d3a435e4f6081a9bbff1d596de705a8360086a587597eadc55e24
glib-2.25.0.tar.gz

This is the first development release leading up to GLib 2.26.

Notes:

 * This is unstable development release. While it has had
  a bit of testing, there are certainly plenty of bugs
  remaining to be found. This release should not be used
  in production.

 * Installing this version will overwrite your existing
  copy of GLib 2.24. If you have problems, you'll need
  to reinstall GLib 2.24.

 * GLib 2.26 will be source and binary compatible with
  the GLib 2.24 series; however, the new API additions
  in GLib 2.25.0 are not yet finalized, so there may
  be incompatibilities between this release and the final
  2.26 release.

 * Bugs should be reported to http://bugzilla.gnome.org.


About GLib
==

GLib is the low-level core library that forms the basis for projects
such as GTK+ and GNOME. It provides data structure handling for C,
portability wrappers, and interfaces for such runtime functionality as
an event loop, threads, dynamic loading, and an object system.

More information about GLib is available at:

 http://www.gtk.org/

An installation guide for the GTK+ libraries, including GLib, can
be found at:

 http://developer.gnome.org/doc/API/2.0/gtk/gtk-building.html


Overview of Changes from GLib 2.24.0 to GLib 2.25.0
===

* The GSettings framework has been merged. This provides the API to
  replace GConf. DConf will provide a backend implementation for it.
  GConf will also provide a backend implementation to ease the
  transition. We provide utilities to assist with schema conversion
  and data migration, as well as a porting guide.

* Translation updates:
 Bengali
 Catalan
 Danish
 Gujarati
 Marathi
 Thai
 Traditional Chinese

Both replies seem to be saying the same thing, but I still don't
understand why the attribute values need to be stored in other columns.
 Also I don't see how storing the attributes in other columns affect an
individual cell.

So this is the way to control the editability and sensitivity of a
single cell without changing the cells above and below the cell in the
same column.  Does this apply for all attributes?

Thanks,

dhk
