Bindings

Can bind view components to view components

Model properties can be @Bindable and available from Controller and View

Validation is available within bindings

bind ( source: c1, sourceProperty: ‘text’ target: c2, targetProperty: ‘text’ )

Binding example (view)

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

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

Image Viewer Demo

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!
