http://skrishnamachari.wordpress.com/2012/01/31/pharo-application-framework-... Obliged for feedback ... For details and links.. Sharing this little framework that should go some way to ease creating large applications ( currently morphic oriented). AbstractMorphicView subclass: #MyNewView ⦠#createMorphsSpecs ^{ âpanel1â² -> #SomeOtherView. âlabel1â² -> #LabelMorph. âtext1â² -> #PluggableTextMorph. âbutton1â² -> #PluggableButtonMorph. } layoutSpecsArray ^{ âwidgetNameInMorphsDictionaryâ -> { #fractions -> (0 @ 0 corner: 1 @ 0.5). â fractional value 0 to 1 range â #offsets -> (10 @ 10 corner: 0 @ 0). â offsets relative to the fractional position â }. â⦠add other widgetspecsâ¦â } Thats it.. you should have a prototype UI neatly laid out.. and then specify: #morphsPrimaryPropertiesSpecs and #morphsSecondaryPropertiesSpecs for full functionality that composes views inside views and scales well. AbstractSimpleMorphicView can make it simpler for TableLayout stuff without requiring #layoutSpecsArray. ..... the main post has other details and links to package...
