[java-gnome-hackers] Tree/List widgets

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

hi,
I've been working on these widgets. My initial aims were to implement
the minimum methods required to get something to work. I have
implemented these and written examples/gtk/tree/TreeExample.java to
demonstrate them. 
Unfortunately, I am having trouble to get this to work. 

In order to get this far, I had to make a few changes to some glib
classes:
Type: renamed the jni ...get_STRING method to getSTRING in both the java
and c files. (This will also have to be done with the other types)

Value: Added temporary methods for assigning values to the object.

The offending line in my test app appears to be:
Value val = new Value( Type.STRING() );
and in Value:
public Value(Type type) {
		int [] vptr = new int[1];
		Value.g_value_init(vptr, type.getHandle());
		handle = vptr[0];
}

I've attached the full java output.

I don't think the iter != null assertion is relevant to this particular
error (the iter isn't involved in the value). However, it too is a
strange error. There is no way of creating a new TreeIter.
list_store_append should create and return the iter.


Also, on a different note, How do I get access to the properties of the
objects (I don't really know much c). Take GtkCellRendererText for
example; This has no get/set methods, but has many read/write
properties. I assume something has to be added to the jni files.
