Hello, Konstantin: Thanks you for your response. I noticed that the project you mentioned was done with QT5. But there is a multi-thread problem when osg works well with QT5. My application really needs multi-thread functionality the load and unload data continously. Do you have osgqtquick project using QT4? Regards, Glen

Project osgQtQuick now based on Qt5. The Qt4 not supported.
</div>
<div>

<div>
Threaded rendering now supported. You can set environment variable
<span style="color: rgb(51, 51, 51); font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Helvetica, Arial, sans-serif, 'Apple Color Emoji', 'Segoe UI Emoji', 'Segoe UI Symbol'; font-size: 15px; background-color: rgb(250, 250, 250);">QSG_RENDER_LOOP </span>
<span style="background-color:rgb(250,250,250);color:rgb(51,51,51);font-family:-apple-system,BlinkMacSystemFont,"Segoe UI",Helvetica,Arial,sans-serif,"Apple Color Emoji","Segoe UI Emoji","Segoe UI Symbol";font-size:15px;">to the value of "basic", "windows" or "threaded" also.</span>

For asynchronous loading, you can use type osgDB.Loader.

<p><span style="font-size:16px;">Hi All,</span></p>
<br />
<br />
<br />
<p><span style="font-size:16px;"><span style="white-space:pre;"> </span>Now I use QT4.8.7 as my application's GUI framework(it seems that there is no other better choice ), it works well with OSG. My users want me to upgrade my GUI, they said the GUI is too old and obsolete, so I plan to use QML technology to do this task. But how to embed QGLWidget into qml, i searched the solution on the internet, all of which is taken with QT5. But I knew there is some problem with multi-thread model when integrating OSG into QT5. So I raise this question, hope to see your replies.</span></p>
