I changed the call to look like the one for gtk >= 2.14 (i.e, Path
instead of nil) and now I can open the options dialog.
I really don't know gtk2, but maybe the differentiation is needed for an
earlier version of gtk and not 2.14?
Maybe < 2.12 should be there
I wouldn't know, as I said I know nothing about gtk, but the available
documentation doesn't mention if and when the api was changed:
https://developer.gnome.org/gtk2/stable/GtkTreeView.html#gtk-tree-view-set-cursor
I checked gtktreeview.c starting from gtk 2.0
https://git.gnome.org/browse/gtk+/tree/gtk/gtktreeview.c?h=gtk-2-0
until gtk 2.24
https://git.gnome.org/browse/gtk+/tree/gtk/gtktreeview.c?h=gtk-2-0
and the implementation of gtk_tree_view_set_cell basically didn't change
(apart form the introduction of gtk_tree_view_set_cursor_on_cell in gtk
2.2).
At the beginning of the function there is
g_return_if_fail (path != NULL);
so I guess path should never be null and the LCL implementation works
just because nobody else is using an older gtk.
Maybe the function could be simplified to
lisFocused:
begin
//gtk2 iter has no focus??
Path := gtk_tree_path_new_from_string(PChar(IntToStr(AIndex)));
if GTK_IS_TREE_VIEW(MainView) then
gtk_tree_view_set_cursor(PGtkTreeView(MainView), Path, nil,
False)
else
if GTK_IS_ICON_VIEW(MainView) then
gtk_icon_view_set_cursor(PGtkIconView(MainView), Path, nil,
False);
gtk_tree_path_free(Path);
end;
of course I may be guessing wrong.
Should I file a bug report?
Bye
