Touch Screen Controls - Madaxe - 08-20-2020
we recently installed a touch screen on the manufacturing floor and i could not understand initially why our application would not register mouse click events. Until i figured out there is a seperate set of visualevents for this.
I'm not a developer, so I need a little help i tried to reuse the three visualEventSource3D.MouseEnter,visualEventSource3D.MouseLeave and visualEventSource3D.MouseClick but with visualEventSource3D.TouchEnter, visualEventSource3D.TouchLeave and visualEventSource3D.TouchUp
but i cant get it to work can somebody show me how?
Thanks

Code:

{
ClearMouseOverBoxVisual();
var hitBoxVisual3D = e.HitObject as BoxVisual3D;
if (hitBoxVisual3D != null && !ReferenceEquals(hitBoxVisual3D, this._currentlySelectedBoxVisual3D))
{
this._savedMouseOverMaterial = hitBoxVisual3D.Material;
hitBoxVisual3D.Material = this._mouseOverBoxMaterial;
this._currentMouseOverBoxVisual3D = hitBoxVisual3D;
}
Mouse.OverrideCursor = Cursors.Hand;
};
visualEventSource3D.MouseLeave += delegate (object sender, Mouse3DEventArgs e)
{
var hitBoxVisual3D = e.HitObject as BoxVisual3D;

this._currentMouseOverBoxVisual3D = null;
