globalmapper.SetChangeViewCallback3D

globalmapper.SetChangeViewCallback3D(GM_3DChangeViewCallbackFunc aCallbackFunc, int aUserData) → None[source]

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.

Provide 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.

Parameters:

  • aCallbackFunc (GM_3DChangeViewCallbackFunc) – The function to be called

  • aUserData (int) – The data to update the view

Returns:

Nothing

Return type:

None
