Re: GList strange behavior

Hi,

> In button_cb()...
Did you mean Last list element: 0x832c610 is differ from INIT list
prt: 0x830f080?

It's clear because  0x830f080 was the location of first list and
0x832c610 is the last appended list.
g_list_prepend() return to the start of the list, g_list_last() return
the last of the list (address).

> in test_glist()
First you call temp = g_list_insert(test, ...), test = NULL, save the
list to temp pointer to GList,
second, you call temp = g_list_append(test, ...), nothing wrong with
that code! BUT if you suppose to insert 2nd list here, then you are
wrong. Because, test is STILL NULL. It returns the newly allocated
list again, that's why it's differ. You should call call temp =
g_list_append(temp,...) or to insert the next list.

Just pass it through callback's argument or declare it as global variable.
