I took the Simple example from the Glide example and added the code below. I expected to see a horizontal red line, but don’t see it. I’m sure I’ve missed something obvious.
// Load the Window XML string.
window = GlideLoader.LoadWindow(xml);
// added by me
window.Graphics.DrawLine(Colors.Red, 5, 0, 75, 100, 75);
// also tried window.Render();
window.Invalidate();
