Re: gtktextview with gdkpixbuf saving into file
anyone know a way to save a gtktextview/gtktextbuffer with embedded
gdkpixbuf into a file. I am calling gtk_text_buffer_get_slice then
g_file_set_contents. Idealy it will be good if i can just call
g_file_get_contents to output the saved buffer onto the gtktextview.
void save_grt (GtkTextView *textView, const gchar *dstFileName) {
GtkTextBuffer *buffer;
GdkAtom grtSerializeFormat;
GtkTextIter startIter;
GtkTextIter endIter;
guint8* serializedData;
gsize length;
buffer = gtk_text_view_get_buffer (textView);
grtSerializeFormat = gtk_text_buffer_register_serialize_tagset (
buffer, //GtkTextBuffer *buffer,
NULL // const gchar *tagset_name
);
gtk_text_buffer_get_bounds (buffer, &startIter, &endIter);
serializedData = gtk_text_buffer_serialize (
buffer, // GtkTextBuffer *register_buffer,
buffer, // GtkTextBuffer *content_buffer,
grtSerializeFormat, // GdkAtom format,
&startIter, // const GtkTextIter *start,
&endIter, // const GtkTextIter *end,
&length // gsize *length
);
// gboolean success =
g_file_set_contents (dstFileName,
serializedData, // const gchar *contents,
length, // gssize length,
NULL // GError **error
);
g_free (serializedData);
gtk_text_buffer_unregister_serialize_format (buffer,
grtSerializeFormat);
} // *** of void save_grt
void open_grt (GtkTextView *textView, const gchar *srcFileName) {
GtkTextBuffer *buffer;
GdkAtom grtDeserializeFormat;
GtkTextIter startIter;
GtkTextIter endIter;
guint8* serializedData;
gsize length;
// gboolean success =
g_file_get_contents (
srcFileName,
(gchar **)&serializedData, // gchar **contents,
&length, // gsize *length,
NULL // GError **error
);
buffer = gtk_text_view_get_buffer (textView);
grtDeserializeFormat = gtk_text_buffer_register_deserialize_tagset (
buffer, //GtkTextBuffer *buffer,
NULL // const gchar *tagset_name
);
gtk_text_buffer_deserialize_set_can_create_tags (
buffer, grtDeserializeFormat, TRUE);
gtk_text_buffer_get_bounds (buffer, &startIter, &endIter);
gtk_text_buffer_delete (buffer, &startIter, &endIter);
// gboolean success =
gtk_text_buffer_deserialize (
buffer, // GtkTextBuffer *register_buffer,
buffer, // GtkTextBuffer *content_buffer,
grtDeserializeFormat, // GdkAtom format,

);
g_free (serializedData);
gtk_text_buffer_unregister_deserialize_format (buffer,

Re: Handler disconnect vs. block

Off the top of my head I can think of one: block/unblock will certainly not change handler order, while disconnect/connect may. Overhead must not be significant unless you are doing it say 1 times a second. > One thing I don't like about block/unblock is that GTK issues a warning when > you try to unblock a handler that is not blocked, but there is no way to > ask first whether the handler is currently blocked. disconnect/connect > offers the handler_is_connected query. It seems g_signal_handler_find() could be misused for this, though in any way this will be ugly.

Tips on translating to other languages
Hi All, I'm working on a very large Application that has already shipped in multiple languages on Mac and Windows. There's a whole scheme in place which already works to extract strings from a special text file so I don't need to use any of the gettext stuff as described in the gtkmm documentation here: http://www.gtkmm.org/docs/gtkmm-2.4/docs/tutorial/html/chapter-internationalization.html My question is, how do I tell gtk to load the Spanish version of system dialogs (e.g. the File Open dialog).

Handler disconnect vs. block
Is there a reason to block/unblock a handler rather than disconnect/connect it? Is the overhead for block/unblock significantly lower? One thing I don't like about block/unblock is that GTK issues a warning when you try to unblock a handler that is not blocked, but there is no way to ask first whether the handler is currently blocked. disconnect/connect offers the handler_is_connected query. -- Jeffrey Barish ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
GtkIconView and missed highlight of the row
Hi, I created a gtkcellrenderer this way: pixbuf_cell = gtk_cell_renderer_pixbuf_new(); gtk_cell_layout_pack_start (GTK_CELL_LAYOUT (img_struct->thumbnail_iconview), pixbuf_cell, FALSE); g_object_set (pixbuf_cell, "width", 115, "xalign", 0.5, "yalign", 0.5, NULL); gtk_cell_layout_set_attributes (GTK_CELL_LAYOUT (img_struct->thumbnail_iconview), pixbuf_cell, "pixbuf", 0, NULL); And then I set some things on the iconview: gtk_icon_view_set_selection_mode (GTK_ICON_VIEW (img_struct->thumbnail_iconview), GTK_SELECTION_MULTIPLE); gtk_icon_view_set_orientation (GTK_ICON_VIEW (img_struct->thumbnail_iconview), GTK_ORIENTATION_HORIZONTAL); gtk_icon_view_set_column_spacing (GTK_ICON_VIEW (img_struct->thumbnail_iconview),0); gtk_icon_view_set_row_spacing (GTK_ICON_VIEW (img_struct->thumbnail_iconview),0); gtk_icon_view_set_columns (GTK_ICON_VIEW (img_struct->thumbnail_iconview), G_MAXINT); gtk_container_add (GTK_CONTAINER (thumb_scrolledwindow), img_struct->thumbnail_iconview); The problem is that when I click on the thumbnail in the iconview it's not highlighted with the blue background color. Can you explain me where I'm wrong? -- Colossus Xarchiver, a Linux GTK+2 only archive manager - http://xarchiver.xfce.org ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
