disable pragmas that turn off specific warnings for MSVC. Unfortunately it's presence is only checked in osg/Export header, making other Export headers disable warnings no matter what, which is kind of incoherent. My fix adds #include <osg/Config> to every Export header. I've also unified checking whether to disable warnings to current osg/Export way: #if defined(_MSC_VER) && defined(OSG_DISABLE_MSVC_WARNINGS). Attachment contains all changed Export files in their original locations."

\namespace osgGA
|
|
|
|
The 'GA' in osgGA stands for 'GUI Abstraction'; the osgGA namespace provides facilities to
|
|
help developers write the glue to allow the osg to work with varying window systems.
|
|
|
|
As a cross-platform, window system-agnostic class library, the OpenSceneGraph
|
|
has no direct ties to any given windowing environment. Viewers, however, must at
|
|
some level interact with a window system - where Window system may refer to a windowing
|
|
API, e.g. GLUT, Qt, FLTK, MFC, ...
|
|
|
|
There is much commonality in the implementation of Viewers for varying windowing
|
|
environments. E.g. most Viewers will update a Camera position in response to a mouse
|
|
event, and may request that a timer be started as a result of a model being 'spun'.
|
|
|
|
The purpose of the osgGA namespace is to centralise the common areas of this
|
|
functionality. The viewer writer needs then only write a GUIEventAdapter, a
|
|
GUIActionAdapter, and assemble a collection of GUIEventHandlers
|
|
as appropriate for the viewer.
|
|
|
|
Events from the windowing environment are adpated, and then fed into the GUIEventHandlers.
|
|
The GUIEventHandlers analyse and take action, and make requests of the windowing
|
|
environemnt via the GUIActionAdapter. The viewer writer should then honour these
|
|
requests, translating them into calls to the windowing API.
