Any programming interface for touch pointer on Win8

    Question

  • I notice that there is a touch pointer in RDP activex, is there any way to deploy a touch pointer in a application? 

    I'm working on a app, I have to implement something like trackpad on laptop computer, that should be either a software trackpad or something like touch pointer in RDP activex.    I think it should be much more simple if there are any interfaces about the touch pointer.

    You can refer the app from Windows App store named "Remote Desktop".  Thanks.

  • There is no built in functionality to map the pointer messages like this. Your app will receive them and can map them internally however it likes. This is what the RDP interface does: it receives the normal messages but maps them internally when sending them to the remote system.

  • What do you mean by deploying a touch pointer?

    Your app can respond to pointer input by listening to pointer messages or manipulation messages. A software trackpad would typically listen to PointerPressed, PointerMoved, etc. and convert those to internal commands.

    I'm sorry Rob I didn't describe the scenario clearly.  What I said was about something like the "Touch pointer " feature in RDP activex,please refer to :http://msdn.microsoft.com/en-us/library/windows/apps/hh994980.aspx.  I was not talking about the common pointer input.

    With such a "Touch pointer", the user can move the cursor around the whole screen by moving their finger a very short distance on the screen. In fact, the user can set the speed of the "Touch pointer" by himself. The benefit of this feature is when the user is filling some tiny text box(for example), their finger will not cover the desired area on the screen.

    Thanks.
