2 What is WPF?

3 WPF: Windows Presentation Foundation Renders graphical elements (through DirectX) Can be programmed with Visual Studio The view Written in XAML (Extensible Application Markup Language) Visual Studio provides a wysiwyg tool The application core Written in C#

4 What is WPF? Native libraries C# allows to use native libraries You sometimes need to write a wrapper C# can access most of the WinRT library WinRT offers a simple API Gives access to devices such as: Sensors GPS etc. C# Wrapper C++ library

5 Getting started with WPF?

6 Step 1: Create a WPF project In Visual Studio, create a new project (with a new solution) File -> New -> Project -> WPF Application

7 Getting started with WPF? Step 2: Run your project Click on the play button

8 Getting started with WPF? Step 3: Open the XAML file The file « MainWindow.xaml » is a XML file that represents the view Double click on it. The wysiwyg editor should open

9 Getting started with WPF? Step 4: Display the Toolbox The toolbox allows to add new controls in your view but… You must configure Visual Studio to display it!

10 Getting started with WPF? Step 4: Display the Toolbox You can change the Toolbox parent panel by Drag and Drop

11 Getting started with WPF? Step 5: Add a label Just drag and drop a Label from the Toolbox to the view

12 Getting started with WPF? Step 6: Change the style In the main view, select the label and open the Properties panel

13 Getting started with WPF? Step 6: Change the style If you cant find the Properties panel, you will have to add it!

14 Getting started with WPF? Step 6: Change the style In the Properties panel, set the font size to 34px Being able to modify the UI style through the Visual Studio interface avoid loosing a lot of time.

15 Getting started with WPF? Step 7: Add other UI elements Add the following elements: An other Label A Textbox A Button An empty Label

16 Getting started with WPF? Step 8: Add Name properties A name allows to identify a field and to retrieve it in your program To retrieve the content of the Texbox, add a name propertie to your Texbox (Select the Textbox and click on the properties panel)

17 Getting started with WPF? Step 8: Add Name properties Add a name property to the output Label

18 Getting started with WPF? Step 9: Add a handler A handler intercepts the actions that come from the user Set the name property for the button (use « Click » for example) Create the handler with Visual Studio In the design view, double click on the button Visual Studio will create the handler for you The name of the handler will be send_Click (if you named you button « Click »)

19 Getting started with WPF? Step 9: Add a handler You should be automatically redirected to the C# file editor

20 Getting started with WPF? Step 9: Add a handler The function send_Click will be called when a user click on the button Add some content to the handler

21 Getting started with WPF? Step 9: Add a handler In WPF, if you define a name property to a control, you can access this one in the C# file by using its name (for example myInput for the Textbox and output for the Label here) As you can see, adding a handler is easy and it is also quite simple to access the view elements

22 Getting started with WPF? Step 10: Run your program Put a name in the Textbox and click on the Button

23 Conclusion

24 In this part, weve seen some basics about WPF You should be able to add some control and retrieve inputs from the user now WPF provides very efficient tools to design UI WPF is simple The wysiwyg tool is adapted to UI creation Visual Studio allows us to be efficient WPF is powerful You can access native libraries Forced separation between the view and the rest of the application is a good practice
