PointerExited not firing

Question

We are developing a Metro/DirectX app in C++, and we need great support for both mouse, stylus and multi-touch finger and allow the user to switch between them at ease. To do this, we keep an internal state of the current input state. However, sometimes when we stress-test this (multiple input methods at the same time) we get a PointerEntered event without a matching PointerExited event, which messes things up. Should we be able to rely on always getting a PointerExited event for each PointerEntered? I've also tried to listen to PointerCaptureLost to see if that was the issue, but no luck.

Also, found this issue that looks a bit similar (but not quite, as it's talking about PointerPressed/Released)

Answer 1

I am also seeing this issue. In a simple application I don't have this issue, but when the CPU is getting pegged I end up with missing PointerExited events. The docs don't mention the possibility of a PointerEntered without a matching PointerExited, and in our case it's causing a bug in our application. I can't reproduce this in WPF or Silverlight, so I'm thinking it's specifically a WinRT bug and not by design. Please advise.

Hello,

 

Would you please provide us the whole codes to reproduce this issue,

 

You can upload your project to skydriver

It is not necessary that you send out the whole of your project. We just need a simplest sample to reproduce the problem. You can remove any confidential information or business details from it.

 

Best regards,

Jesse
