How to get pointer position from PointerRoutedEventArgs en C++/WinRT

[vflich]

Hello,

I'm developing an apllication in WinUI 3 and C++, but I'm stuck with a problem, but I think it must be something simple. I try to get the mouse position in the event OnPointerPressed. Here is my code for the handler function:

void MyWindow:OnPointerPressed(IInspectable const& sender, PointerRoutedEventArgs const& e)
{
auto tb = sender.try_as();
if (!tb) return;

winrt::Windows::UI::Input::PointerPoint pp = e.GetCurrentPoint(tb);
winrt::Windows::Foundation::Point pointerPosition = pp.Position();     // ERROR 

 // More code...

}

I assign the event over a TextBlock and try to get the coordinates of muse click relative to that TextBlock, but this code doesn't compile. They tell me an error in the call to pp.Position(): C3779 'winrt::impl::consume_Windows_UI_Input_IPointerPointwinrt::Windows::UI::Input::IPointerPoint::Position': Can't use a function returning 'auto' before being defined'

Maybe it is simple, but I can't see how to get click position.

Thanks!

(you must include the right header...)
