class | glChartCanvas |
ChartCanvas - Main chart display and interaction component.
Manages the visualization of nautical charts and all chart-related user interactions. This class integrates geographic data, user interface elements, and navigation tools into a comprehensive chart viewing experience. It handles everything from chart loading and rendering to user gestures, route planning, and navigation aids.
ChartCanvas uses ViewPort internally to handle the mathematical transformations between geographic and screen coordinates. While ViewPort focuses on the projection math, ChartCanvas manages the actual rendering, user interaction, and application logic.
As a wxWindow subclass, it responds to paint, mouse, keyboard, and other window events, translating them into appropriate chart operations like panning, zooming, and object manipulation.

This function is called to update the canvas position, scale, or rotation during animated panning, zooming, or rotating operations. The amount of movement performed is determined by the elapsed time parameter dt
, and the operation continues as long as the internal movement timer is nonzero.
