- Document windows A new SketchFlow document opens a start page by default. As you create more navigation screens, they will be opened, and can be selected here. ArtboardThe artboard is your main screen or canvas; you will add various elements such as images, text and forms, and arrange them on the artboard. The artboard represents the authoring view of your application. SketchFlow Map panel The SketchFlow Map panel at the bottom of the screen is a graph editor that allows you to define the various screens in your application. The blue rectangle labeled Start is a node, and by default, represents the initial navigation screen. Hovering over any node expands a section allowing you to create new screens, connections, and components, as well as change the visual tag associated with these nodes. The Tools panel The Tools panel allows you to create and modify objects in your application. You create objects by selecting the tool and drawing on the artboard with your mouse (or a tablet, if connected). Tools with a white rectangle in the bottom right corner expand to display more tools when you click them.
- The SketchFlow map shows you all screens composing the prototype and the connections (navigations) between those screens. When you create a new SketchFlow application with Expression Blend 3 you will probably see that map in the center bottom part of the screen, otherwise you can open it from the Window->SketchFlow Map menu.The SketchFlow map shows you all screens composing your prototype and the connections between them. At each moment you can add a new screen to your prototype.
- the customer often focuses on the wrong things and also the customer easily tempts into thinking that they are seeing more than there is. That’s why the SketchFlow comes with a built-in sketchy style, which makes controls look as if they were drawn on the white board in the office. Adding to this the various drawing tools and the sticky notes, the designer has a complete set of tools for sketching and prototyping.All sketch controls (styles) may be found in the Assets panel (Windows -> Assets), under the node SketchFlow -> Styles -> SketchStyles.
- The SketchFlow map shows you all screens, composing your prototype and the connections between those screens. In order your prototype to be complete and to give the customer a full vision about the flow, the customer must be able to navigate (switch) between the different screens
- Making mock up data is sometimes painful, especially if you need to do that for an early prototype. Never more – Blend lets you create meaningful sample data just with a few clicks; you can create working data – bound lists and master – details views just with drag and drop. You can define sample data in the Data pane. You may import data from a XML file or you may choose to use the built in data which Blend offers you. Binding to a list control is just a piece of cake. Just select the collection and drag it onto the desired control.
- One of the purposes of the prototype is to quickly and easily express your ideas. There is no better way to do this but to use animations. Since you are using Expression Blend , you have a complete set of key frame-based animation tools. Key frame animations are powerful but not effective for prototyping. You simply have to create and manage too many frames, and that will slow down your work. That’s why SketchFlow offers you a special type animation called “SketchFlow Animation” which purpose is to show the customer what happens on that screen step by step. By default the SketchFlow Animation pane is placed on the center top part of the screen (just above the main design surface).You just add a storyboard frame, making your screen look the way you like. Repeat that procedure as many times as you want. It is extremely simple and most important – it is fast. For each storyboard frame you may specify how long to show that frame (Hold Time) and how long to take the transition from the previous frame to the current one (Transition Time). Also the SketchFlow animation allows you to set an easing function for the transition (by default it is Cubic InOut).
- The SketchFlow player is an extremely important part of the prototype. Once you have the prototype ready you may ask yourself how you will interact with the customer. This is what the SketchFlow player is used for. The big advantage is that you don’t need any additional software to run the player (of course you will need the Silverlight plugin installed in your browser). If your prototype is for WPF then the player is an ordinary application. If your prototype is for Silverlight then the player will run in the browserThe player allows anybody who explores the prototype to give an immediate feedback. You can insert comments or use ink to draw directly on the prototype.After that you just turn back the prototype to the designer, who can insert it in the Blend art board. Gathering timely feedback from a client is just as important as creating the prototype. That’s why the player is extremely important part. It helps reducing the time lost and costs in the design and development process. It is freely distributed and can be run on a standard browser. Clients review the prototype, make some tests, provide in context feedback and send back the demo to the designer.
- Every project needs design documentation. SketchFlow can export your prototype to a Microsoft Word. Just use the File->Export to Microsoft Word command. The document will contain screenshots of the SketchFlow Map, as well as screenshots of every screen you have in the project; table of contents and table of figures.
