    <p>First, get the <code>GtkTextBuffer</code> from the <code>GtkTextView</code> using <code>gtk_text_view_get_buffer()</code>. Then get the start and end <em>GtkTextIters</em> from the buffer to use to get the text of the buffer. Finally, write that text to the file using the API of your choice, however, I would recommend <code>Gio</code>. Here's a snippet from my old tutorial:</p> <pre class="lang-c prettyprint-override"><code>gtk_widget_set_sensitive (text_view, FALSE); buffer = gtk_text_view_get_buffer (GTK_TEXT_VIEW (editor-&gt;text_view)); gtk_text_buffer_get_start_iter (buffer, &amp;start); gtk_text_buffer_get_end_iter (buffer, &amp;end); text = gtk_text_buffer_get_text (buffer, &amp;start, &amp;end, FALSE); gtk_text_buffer_set_modified (buffer, FALSE); gtk_widget_set_sensitive (editor-&gt;text_view, TRUE); /* set the contents of the file to the text from the buffer */ if (filename != NULL) result = g_file_set_contents (filename, text, -1, &amp;err); else result = g_file_set_contents (editor-&gt;filename, text, -1, &amp;err); if (result == FALSE) { /* error saving file, show message to user */ error_message (err-&gt;message); g_error_free (err); } g_free (text); </code></pre> <p>Check out the following API documentation:</p> <ol> <li><a href="http://developer.gnome.org/gtk3/stable/GtkTextBuffer.html" rel="nofollow">http://developer.gnome.org/gtk3/stable/GtkTextBuffer.html</a></li> <li><a href="http://developer.gnome.org/gtk3/stable/GtkTextBuffer.html" rel="nofollow">http://developer.gnome.org/glib/stable/glib-File-Utilities.html</a></li> </ol>

    1. COBy the way, `result` is a gboolean, `buffer` is a GtkTextBuffer, `err` is a GError, and `start`/`end` are GtkTextIter. It's taken from this code: http://www.micahcarrick.com/files/gtk-glade-tutorial/C/main.c

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
