[lazarus] GTK Strangeness

[Curtis White]

Does anyone know who did the GTK conversion? The reason I am wondering is that
I think I may have found a bug.

I found some method calls that take a Pgchar as input and if you pass a long
string to them, they get a bunch of errors and don't work. If you typecast the
string to a ShortString, they work perfectly. Yet other procedures that take a
Pgchar work with long strings just fine.

For example, here is what I am talking about.

mmiFile := gtk_menu_item_new_with_label ('');
tmp_key :=gtk_label_parse_uline(GTK_LABEL(GTK_BIN(mmiFile).child), '_File');
gtk_widget_add_accelerator(mmiFile, 'activate_item', accel_group, 
                      tmp_key, gint(GDK_MOD1_MASK), TGtkAccelFlags(0));

All three of these functions require a Pgchar to be passed in (the params with
single quotes). When I had {$H-} at the top of the unit, everything worked
fine. As soon as I changed it to {$H+}, the first two functions kicked out a
bunch of errors and failed at runtime. They compiled just fine. They just
kicked out all kinds of GTK errors when I ran the program and they didn't work.
Then when I changed them to the following, they work perfectly again.

mmiFile := gtk_menu_item_new_with_label (ShortString(''));
tmp_key := gtk_label_parse_uline(GTK_LABEL(GTK_BIN(mmiFile).child),
ShortString('_File'));

Notice the ShortString in them? The third function did not need to be changed
at all. It continued to work just fine even with long strings. I can do the
typecast to fix it for now, but this seems like it is wrong. I checked the
functions in the gtk files and cannot find anything wrong. So I don't know who
to report this to. Does anyone else have any ideas how to fix this or who to
report it to?
