[ wxruby-Bugs-13676 ] xrc listctrl windows custom data crash
...accepted:
@lst.set_item_data(x,[x,x])
I don''t know how it supposed to work, but it seems that the ruby object is converted to long and then back (ListCtrl.i):
VALUE get_item_data(int row)
{
if ( row < 0 || row >= self->GetItemCount() ) return Qnil;
long item_data = self->GetItemData(row);
if ( item_data == 0 ) return Qnil;
return (VALUE)item_data;
}
VALUE set_item_data(int row, VALUE ruby_obj)
{
if ( row < 0 || row >= self->GetItemCount() )
{
rb_raise(rb_eIndexError, "Uninitialized item");
}
long item_data = (long) ruby_obj;
bool result...

listctrl set_item_data
Hi,
I have used set_item_data with ruby objects (an array) and got a crash.
The reason is simple, the objects were deallocated by the GC.
The easy solution would be to accept only long parameters (like the
original interface).
The hard is to play by the GC''s rules and increase the reference count
and decrease on deletion.
Regards,
teki

[741] trunk/wxruby2: Fix get_item_data, hiding TreeItemData messiness, fix GC-ing (Alex Fenton)
...ment, which may be any normal Ruby
+object. Alternatively, a Ruby object can be explicitly associated with a
+TreeCtrl item by calling "set_item_data":#TreeCtrl_setitemdata . The
+same Ruby object can later be retrieved from a TreeCtrlItemId by calling
+"get_item_data":#TreeCtrl_getitemdata .
