Re: [gtk-list] Re: style usage + memory leak

[Eric Harlow <linuxgeek yahoo com>]

Hmm.. it does appear that all objects have a reference count of one
when created.  I suppose the clean way is to do an unref on each
object you create (ug..) during the program.  Otherwise, this
certainly could cause leaks if you don't keep track of the memory.

To let GTK keep free the objects, could just unref the style after
assigning it to the window.  Don't know what kind of damage that might
do.  <g> 

Don't know about the memory hogging though.  Might try replacing
g_malloc with something more informative that keeps track of who's
allocating the memory.  Might show what's going on.
