GM_3DSetChangeViewCallback |
Sets the callback function to be called when a button is pressed (either a pan or zoom button) in the 3D view that would typically result in a new set of data to be displayed in the 3D window.
Syntaxvoid __stdcall GM_3DSetChangeViewCallback ( GM_3DChangeViewCallbackFunc aCallbackFunc, void* aUserData );
RemarksProvide this callback if you want to keep your main view in sync with the 3D view, like in the Global Mapper application. If you do not provide a callback, the default behavior is to just update the data displayed in the 3D view independent of any other view.
