[Gtkpod-devel] a fix for "Next" and "Prev" buttons

[Marcelo V. <mva...@ro...>]

The code I've sent about adding Play/Next/Prev buttons had a bug for next/prev. 

The function bellow replaces the buggy one (in display_songs.c):

void tm_select_next_row (gint Next0_Prev1)
{
    if (track_treeview)
    {
        GtkTreePath *path;
        GdkRectangle rect;
        GtkTreeSelection *selection;
        gint delta;

        gtk_tree_view_get_cursor (  track_treeview,
                                    &path,
                                    NULL);

        if (path == NULL) return;

        gtk_tree_view_get_cell_area     (track_treeview,
                                             path,
                                             NULL,
                                             &rect);
        if (path == NULL) return;

        if (Next0_Prev1) delta = -rect.height/2;
        else delta = rect.height + rect.height/2;

        gtk_tree_view_get_path_at_pos (track_treeview,
                       1, rect.y + delta , &path, NULL, NULL, NULL);

        if (path == NULL) return;

        /* deselect current rows */
        selection = gtk_tree_view_get_selection (track_treeview);
        gtk_tree_selection_unselect_all(selection);

        gtk_tree_selection_select_path  (   selection,
                                            path);

        gtk_tree_view_set_cursor        (   track_treeview,
                                             path,
                                             NULL,
                                             FALSE );

        gtk_tree_path_free (path);

    }
}

Please note that those buttons are different then the ones  I have proposed today to control the player. Those here are about the email I 've sent with a screenshot plus the related source code attached.

Please test it. It seems OK to me to submit.
Cheers,
Marcelo
