<BLOCKQUOTE>Pure virtual base class for adapting the GUI actions requested by CameraManipulators
|
||
into actions which are handled by the GUI toolkit of the users application.
|
||
|
||
<P>There are several was of using the ActionAdapter either inheriting it as
|
||
done with osgGLUT::Viewer class or passing a simple struct to the camera
|
||
manipulator then unpacking the results and working out what to do to respond
|
||
to the requests.
|
||
|
||
<P>Also there are several ways to run your app and handle the updating of
|
||
the window. osgGLUT::Viewer always has a idle callback registered which does a
|
||
redraw all the time. osgGLUT::Viewer can safely ignore both requestRedraw() and
|
||
requestContinousUpdate() as these are happening all the time anyway.
|
||
|
||
<P>Other apps will probably want to respond to the requestRedraw() and
|
||
requestContinousUpdate(bool) and again there is more than one way to handle it.
|
||
You can override requestRedraw() and implement to call your own window
|
||
redraw straight away. Or you can implement so that a flag is set and
|
||
then you then respond the flag being set in your own leisure.
|
||
|
||
<P>requestContinousUpdate(bool) is for enabling a throw or idle
|
||
callback to be requested by the camera manipulator. Again you can respond
|
||
to this immediately by registering a idle callback or a timed callback, or
|
||
you can delay setting the callback and do at you own leisure.
|
||
|
||
<P>requestWarpPointer(int,int) is requesting a respositioning of a mouse pointer
|
||
to a specified x,y location on the window. Used by some camera manipulators
|
||
to initialize the mouse pointer when mouse position relative to a controls
|
||
neutral mouse position is required, i.e when mimicking a aircrafts joystick.</BLOCKQUOTE>
