[java-gnome-hackers] glib Value problems

[Mark H. <mh...@ti...>]

Hi, 
  I've realised that I made a few mistakes when working on the tree and
list widgets. I'm not entirely sure how to fix them, so any help would
be appreciated. 

1)
In gtk.TreeModel, we use gtk_tree_model_get_value.
This initializes and sets a GValue. At present, we are already
initializing the GValue by saying
Value val = new Value( Type.STRING() );
This produces the warning:
GLib-GObject-WARNING **: gvalue.c:86:g_value_init(): cannot initialize
GValue with type `gchararray', the value has already been initialized as
`gchararray'
(but the code does function correctly)
I have not been able to work out how else to create a GValue. Merely
allocating memory to the size of GValue is not sufficient. (various
errors are produced on output - seems like random data is being used)

2)
In glib.value jni code for getting and setting java objects uses
(*env)->NewGlobalRef(. This is then never destroyed by the GC. I think
this should be done by storing a simple gpointer to the object, without
making the global reference, however I have not been successful in
making this work.
