+cws 'atkbridge'
+#Issue number: i#47890#
+Submitted by: mmeeks
+
+Hacked up prototype of atk bridge
+
+
+Serious problems
+ + Threading/locking:
+ + incoming CORBA calls & the GDK lock
+ + how are these being processed & on what thread ?
+ + are we holding the GDK_THREADS lock ?
+ + can we even do that ?
+ + is it really necessary to be thread safe ?
+ + how does this work in combination with the (unsafe) GAIL code ?
+ + what should incoming CORBA calls be doing ?
+ + esp. since we can't tell if they're coming from
+ in-proc or not either [ though this is unlikely ]
+
+
+Test:
+ + in-line text editing, does the TEXT_CHANGED signal get it right,
+ + why not copy/paste/delete etc. ?
+ + check vs. writer & other bits ...
+ + AtkSelection
+ + AtkHyper*
+
+* At-poke
+ + implement non-gui mode - for to-console event logging
+ + logging
+ + more detail from remaining events
+ + add a Tree navigation thing instead (?)
+ + poke a sub-child (?)
+ + embed a tree widget inside the tree view ?
+ + AtkHyperText testing (?)
+
+
+Known bugs:
+ + AtkText
+ + selection interface - multiple selections ?
+ + word boundary issues
+ + copy AccessibleTextImpl.java's getAfterIndex eg.
+ + the 'getFoo' methods need to use UNO_QUERY_THROW &
+ throw an exception to avoid null pointer dereferences.
+ + AtkAttributeSet (etc.)
+ + AtkEditableText
+ + finish/test AtkTable
+ + HyperLink 'link_activated', HyperText 'link_selected' (?)
+ + tooltips create new toplevels with broken roles.
