[osg-users] How to get the Handle for C# displays

[Ernest Abbott]

Hi Glen,

I'm using the Osg.Net libraries (Osg.Net, Osg.DB ... Osg.Viewer)

I'm using OSG version 2.0.0 v7 2007-06-19.

I had tried the most recent version of OSG, but after a while discovered it didn't work with the C# wrappers I was using. 

The error message is "Osg.GraphicsContext.Traits does not contain a definition for inheritedWindowData"

I'm using VS2005 Professional Edition.

regards

Ernest

Ernest,
Are you using osgDotNet wrappers? what version of OSG? what's the error you get when trying to compile traits.inheritedWindowData = ... ? thanks -gw

Hi Glen,

Thanks for the link.  I'd looked at the code before. But there doesn't seem to be an equivalent in C# for the following (left hand side).
traits->inheritedWindowData = new osgViewer::GraphicsWindowWin32::WindowData( hwnd );


Yes, I can get the handle. But traits does not have "inheritedWindowData" or anything that 
looks like it.
 
All traits has is 

addObserver
displayName
Dispose
Equals
GetHashCode

GetType
removeObserver
ToString


I am able to render my image to its own window, but not within a panel I've set up.

regards

Ernest

Ernest,

Here's a code snippet. This is C++/CLI but you will get the idea. Grab the Handle property from your .NET control and pass it to the Traits of your new graphics context:

I'm very very new to OSG. I'm writing in C# and have a limited understanding of C++. I am, as vehicle of learning OSG, converting a sample OSG C++ program to C#. I want to be able to display my rendered image in an area within my windows Form. I realise that I need to get the handle for the render object, which is easily done. But I can't see where/how I can let OSG know what this handle is. ie How can I pass the handle to OSG so that it renders within my window control? 



A bit of sample code would be of a great help.
