• MindMap app using Hyperbolic tree

  I recently came across a Hyperbolic tree implementation on codeplex using WPF and thought that a nice usage of it could be in writing a mind map creating application.... I tweaked some of the original code and got a tree with editable nodes... Its been laying around for sometime, so I thought it best to put it out there so that you folks can continue its development. Though its not functional in the true sense, it does provide the basic functionality like saving and opening (albeit to the same file)... Currently only the text is serialized... The project (VS 2008) is attached Note that the usage of the Hyperbolic tree and its code is under the Codeplex License terms Share this post Read More...

• 3.5 features: Viewport2DVisual3D

  Viewport2DVisual3D .... this new feature makes things a lot easier in the 3D world.. What this enables is putting interactive 2D on 3D. This makes things like having a textbox in 3D a breeze... < Viewport2DVisual3D x:Name = " vp2d_multiple_children " Geometry = " {StaticResource mesh} " > < Viewport2DVisual3D.Material > < DiffuseMaterial Viewport2DVisual3D.IsVisualHostMaterial = " True " Brush = " White " /> </ Viewport2DVisual3D.Material > <TextBox /> </ Viewport2DVisual3D > One other thing is mapping 3D points to 2D is so much more easier... Earlier on I had a post on mapping a mouseclick on a 3d model to a 2d coordinate. This involved using some barycentric coordinates and such... Now all you need is call e.GetPosition(relativeTo) in the mouse event handler... tada!!... your coordinates are ready... so using this new stuff i created a simple app for keeping track of your travels. right clicking on the globe puts a tag on the globe. Clicking on the Read More...

• 3.5 Features: Enabled hyperlinks in RichTextBox

  hmmm... that was one often requested feature. So to enable hyperlinks in RichTextBox all that is needed is to set the property IsDocumentEnabled on the RichTextBox. Type the following in XamlPadX and you have the hyperlink navigation working. < RichTextBox IsDocumentEnabled = " True " xmlns = ' http://schemas.microsoft.com/winfx/2006/xaml/presentation ' xmlns:x = ' http://schemas.microsoft.com/winfx/2006/xaml ' > < FlowDocument > < Paragraph > < Hyperlink NavigateUri = " http://club.live.com " > Live Games </ Hyperlink > </ Paragraph > </ FlowDocument > </ RichTextBox > A couple of things to notice here: 1> The Navigation is possible only on a Ctrl Click operation 2> There is no tooltip to indicate that navigation is possible. You could add this to the Hyperlink. A simpler alternative is to just subclass the Hyperlink and add the tooltip in the constructor public class MyHyperlink : Hyperlink { public MyHyperlink() { this .ToolTip = Read More...

• Microsoft Surface: What WPF Can Do For You

  Today Microsoft announced the Surface , a new line of consumer products that turn "an ordinary tabletop into a vibrant, dynamic surface that provides effortless interaction with all forms of digital content through natural gestures, touch and physical objects. Beginning at the end of this year, consumers will be able to interact with Surface in hotels, retail establishments, restaurants and public entertainment venues." If the videos on the Surface website seem impressive, you haven't even scratched the surface yet. Using the real product is way cooler! The Surface team has thus far been operating under the radar. I'm proud to say that the device runs a variant of Windows Vista and uses Windows Presentation Foundation (WPF) for its user experience. It shows how WPF can be a game changer when you exploit its power. It is understandable that the first generation of the product - shipping in the second half of 2007 - is out of reach of the average consumer, and is focused on businesses. I Read More...
