Windows Presentation Foundation Fabio Santini Windows Presentation Foundation Fabio Santini

Agenda Per iniziare Introduzione a Windows Presentation Foundation Come funziona ? Cosè XAML ? Interactive Designer (Sparkle) Come migrare ? Esempi

Per iniziare … hebeta/default.aspx hebeta/default.aspx Microsoft Pre-Release Software WinFX Runtime Components - January Community Technology Preview (CTP) (2.4 Mb) Visual Studio 2005 (anche se si può fare tutto a manina) Microsoft® Windows® Software Development Kit (SDK) for the January 2006 WinFX® Runtime Components Community Technology Preview (CTP) ( MB) Microsoft Visual Studio Code Name Orcas Community Technology Preview - Development Tools for WinFX® (3.6 Mb)

Per iniziare … Se non funziona il setup Provate a disinstallare Microsoft Command Shell (Monad) e il Compact Framework 2.0 Eseguire il setup chiedendo un log più completo Setup.exe -l*v Se non funziona lelemento MediaElement E probabile che il setup non sia riuscito a sostiture due dll dxva2.dll (DirectX Video Acceleration 2.0) e evr.dll (Enhanced Video Renderer)

La nostra prima applicazione

Step 1: Scriviamo il programma

<ListBox> </ListBox>

Step 2: Compiliamo

BAML C#/VB/etc EXE Images, etc

Step 3: Eseguiamo il programma

Step 4: Mostriamo i pixel

ListBox ButtonButton ScrollViewer StackPanel Render Measure & Arrange

CompNode CompNode CompNode CompNode

DX Surfaces Bitmaps CompNode CompNodeCompNodeCompNode

Step 5: Comunichiamo con lutente

ListBox Button Button ScrollViewer StackPanel Mouse Click! CompNode CompNodeCompNodeCompNode 1.User32 gets the message 2.WPF converts message to an input report 3.If input report is a mouse move… Structural hit testing on visualsStructural hit testing on visuals Geometry hit testing through geometry dataGeometry hit testing through geometry data 4.Convert reports into one or more events 5.For each event… Build event routeBuild event route Raise eventsRaise events

Step 6: Utilizziamo gli elementi

Step 7: Ritorniamo al punto 4 (ricordate: Mostriamo i pixel)

Usiamo XAML

Come migrare ? Integrazione tra i due mondi Un nuovo modo di pensare alle interfacce
