#Win 7 multitouch code
I named my Canvas as canvas and wrote a little code There’s already a wrapper in these libraries so if I take my existing WPF code I can change it to use that API rather than trying to have to figure out anything to do with the gestures myself ( specifically for zoom, rotate, translate ).
Now…that gets me back to that manipulation API that I didn’t want to wrap up the COM interface for.

That makes this stuff all pretty easy – not much that you can really add to that except to say that, again, there’s a more fully fledged demo in the download bits. Void OnPan(object sender, GestureEventArgs e) Rotate.Angle -= e.RotateAngle / Math.PI * 180 Void OnRotate(object sender, GestureEventArgs e) Void OnTwoFingerTap(object sender, GestureEventArgs e) Void OnZoom(object sender, GestureEventArgs e) Void OnPressAndTap(object sender, GestureEventArgs e) GestureHandler handler = Factory.CreateGestureHandler(this)
What about replicating the experience of getting gesture messages into WPF? I made another WPF application with a Rectangle on a Canvas and added references to the sample wrapper libraries Windows7.Multitouch and

So, replicating the experience of getting Touch messages into Windows Forms was easy.

What I find interesting here is that with my virtual CodePlex driver for touch based around 2 mice I see that both mice fire the same touch ID here ( 10 ) when used individually so for me, both of my mice will draw with the same colour until I draw with them together and then they fire different ids and so ( with the code above ) draw in different colours. Note that I make no attempt to store the points connected by lines so invalidating the window will clear the display. G.DrawLine(p, state.LastPoint, e.Location) Using (Graphics g = pnlMain.CreateGraphics()) Void OnTouchHandler(object sender, TouchEventArgs e) It’s almost embarrassingly easy and so I thought I’d add a little code just to draw something in response to the events that are being picked up rather than just writing them into a TextBox – simple enough stuff and there’s a more complex but similar sample packaged with the wrappers so I’m only experimenting rather than making any contribution ? Those wrappers are nice – very easy to pick up the touch messages using those things and I’d say the whole thing took less than 10 minutes rather than me spending a bunch of cycles building some partially-formed wrappers myself. I made a “UI” with a SplitContainer, Panel and a TextBox in it and wrote this code ( adding references to the sample Windows7.Multitouch and assemblies ). I wanted to experiment with those wrappers and see whether it made life easier or more difficult and so I thought I’d quickly replicate what I’d done previously and so I started a new Windows Forms application to see if I could handle WM_TOUCH messages in it. NET world didn’t fill me with joy and so switching to using someone else’s wrapper seemed like a smart move. Wrapping those COM objects might not have been too ugly a job but the initial thought of trying to track down the TLB info for the COM objects involved ( assuming that there is TLB info for those COM objects because it’s a lot less fun if there’s not ) and then try and get it imported into the. Following on from the previous post and the one before, it was fun to play with my own interop wrappers for a while but I figure it’s going to be a lot more productive to use the interop wrappers contained up at Īnd they also include wrappers for the manipulation API and its friend the inertia API which I didn’t really want to get into wrapping if I could avoid it.
