Re: [osg-users] creating widget for Qt
I asked the same question last year - here is the answer http://www.mail-archive.com/osg-users@lists.openscenegraph.org/msg16305.html With QT4.5 I am having to use Adapterwidget because I get a recursive redraw with QOSGWidget which I haven't been able to fix yet. QOSGWidget does work if you switch to the (experimental) Opengl rendering backend with QT but then the rest of the app draws very slowly. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=8786#8786 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] creating widget for Qt
Hi Sajjad, The warnigs are because I'm rendering in a QWidget out of the paint event. These warnings doesn't appear if you render in a QGLWidget, but the CompositeViewer framework with multiple OSG views in different widgets and multi-threaded does no render properly (at least for me [Crying or Very sad] ) Recently I moved to Qt 4.5.0 and I had a new problem with undesired repaint event when the OSG widget lost the focus. For example when a modal dialog is shown, my QWidget embbeding the osg::View is repainted with the background color and the content are removed until the osg widget recovers the focus and is repainted again. I solved this problem using QWidget::setUpdatesEnabled(false) but still I have the problem of the warnings. I think is not the same situation than yours because you are extending from AdapterWidget, but tell if you discover something ;) Regards, Iván -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=8755#8755 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

I don't use .pro files, but I have to include the OpenGL module because I extend from QGLWidget.

Re: [osg-users] creating widget for Qt
Hi Sajjad, Personally I create the whole interface in Qt designer and leave the OSG widget/s integration in the initialization code. About the header file, I 've separated the code from the original OSG file in my own files (.h and .cpp) As you can see in the Qt sample you have different options to render OSG in a Qt widget. This works for me except for some warnings because of rendering out of QPainter events, but I will deal with this later :) I hope this help you in some way, Iván. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=7966#7966 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] creating widget for Qt
Hello forum, I would like to create a viewer widget for osg using the Qt designer. To promote it i need the corresponding header file to that. As i see in the source you have the class declaration and definition in a sigle .cpp file. Do i have to separate them or the header file is located somewhere else that i did not find. Any hint?
