[osg-users] Update scene while moving window

[Frank Bergmann]

Actually, depending on the version of windows that you are running it might
also be a windows setting that prevents the window to be redrawn while
moving. Have a look at (under XP): 

 

Control Panel\System Properties\Advanced\Visual Effects 
Settings\Visual
Effects

 

In that checked listbox, look for an entry saying “Show window contents
while dragging”. With that enabled I see the scene updated while dragging
the window 
 

 

Cheers

Frank

Hi,

you are right, i'm running on Windows platform. 
Right now i'm converting my application from osgProducer::Viewer to
osg::CompositeViewer.
Using osgProducer::Viewer it was possible to move the window without any
problems. 
The scene was updated in contrast to osg::CompositeViewer (OSG 2.2).

But what is the difference between these two viewers?

Thanks in anticipation

Hello André,
 
  

There might be a way to avoid this by using a separate thread for message
dispatching in the GraphicsWindowWin32 class, but that remains to be
explored.
    

 
And in fact, I imagine that's what video players like Windows Media 
Player do, since you can move the window while video is playing and it 
will not pause.
 
Not suggesting anything be done about it, just adding a point to consider...
