Bindings

Can bind view components to
view components
Model properties can be
@Bindable and available from
Controller and View
Validation is available within
bindings

Binding example (view)
def counter = 0
application(title:'bindfun', pack:true, locationByPlatform:true) {
gridLayout( cols:1, rows:2)
button(quot;Click mequot;, id:'b')
label(id:'lbl', text: bind( source: b,
sourceEvent: 'actionPerformed',
sourceValue: { counter++ },
converter: { lbl.text + it}
)
)
}

11.
MVC Groups
MVC pattern can have a very small footprint
Can be in lots of places
Griffon’s MVC groups allows easy creation and
deletion of MVC pattern
griffon create-mvc to create skeleton
createMVCGroup() to instantiate in running app

Plugins
10+ available
griffon list-plugins
griffon install-plugin myPlugin
Just like Grails

Thoughts
Swing is painful
Griffon is good
Missing documentation (only 0.1)
Great potential for growth
I wish I had this 3 years ago!
