Testing for left button click while in a MouseMove Event
Posted: 05 Oct 2022, 12:09
Hey y'all,
I'm working on gaining a greater understand of WPF, xaml, and NoesisGui. To that end I'm trying to drag and drop a single red rectangle in canvas element, as per this tutorial I've found online:
https://www.youtube.com/watch?v=THV5BW5WW_o
I am aware of the behaviors-based approach outline in the Noesis Tutorial and sample code, but there are quite a few other xaml concepts in that tutorial which I don't fully understand, so I thought it worthwhile to start a lot simpler.
I've hooked up NoesisGui to register mouse events and I have following xaml setup:
with the following native code:
With the Visual studio debugger I can tell that the MouseMove event is triggered properly. However, the args.leftButton appears to never evaluate to true, despite me verifying that I do pass left clicks on to NoesisGui. Any ideas as to where this is all going side-ways or perhaps how I can debug this further?
Cheers,
Gazoo
