I have made a test app with XAML + WPF + IronRuby event handlers
(IronRuby revision 76). The code of the Ruby-part (EventManager.rb) is
below. Due to lack of other working mechanisms of connecting the
Ruby-methods to the WPF-events, I ended up in passing the widget
reference to Ruby in a global variable and then using the closure-syntax
to connect the delegates on Ruby-side.
All three events work ok and the App runs, but only with following event
names:
CLR name of the event Name of event seen in IronRuby
"Click" "click"
"Loaded" "loaded"
"MouseEnter" "MouseEnter"
Notice that whereas "Click" and "Loaded" mapped to their lower-case
equivalents, the "MouseEnter" event connected only if it was written in
the original capital form "MouseEnter" on IronRuby-side. The most
logical alternative "mouseEnter" caused MethodMissing. I suspect such
inconsistency in the name-mapping cannot be intentional.
