Detailed Description

The HNPanel class provides a HOOPS/MVO-specific implementation of the Winforms Panel class.

HNPanel creates and manages the connection of a HOOPS/3dGS driver instance to a Panel object, which includes redrawing the scene during exposes/resizes. It also encapsulates passing of mouse/keyboard events through to corresponding MVO operator methods.

This is the base class from which a custom HNPanel class should be derived, and should be used when the application is using both HOOPS/MVO and HOOPS/3dGS


Constructor & Destructor Documentation

hoops_panel.HNPanel.HNPanel ( ) [inline]

Constructor which attaches paint, panel-resize and MouseEvents with corresponding EventHandlers
