 Posted: Thu Apr 10, 2008 4:35 am Post subject: What to do about next() in ListG |
 |
|
There are first() and last() in glib.ListG, and what about the next()?
Here is something in documents of GTK+:
g_list_next()
| Code: | | #define g_list_next(list) |
A convenience macro to gets the next element in a GList.
list : an element in a GList.
Returns : the next element, or NULL if there are no more elements.
In addition, these codes run failed:
| Code: | ListG columnList = dataGridTreeView1.getColumns();
writefln(columnList.length()); |
Are there something wrong? Thanks for any help! |

svn r493 adds next and previous.

It works in the small test i did, it could be that getColumns() returns null (an empty list), then the call to length() will get you a segfault. |
