[osg-users] Fwd: creating widget for Qt
Hello Ivan, What is the difference betwen the AdapterWidget and QOSGWidget. I found one to be the subclass of GLWidget and the other is QWidget. Which one is better ? Any explanation? Regards Sajjad -- Forwarded message -- From: Iván Cuevas Date: 2009/3/19 Subject: Re: [osg-users] creating widget for Qt To: osg-users@lists.openscenegraph.org 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 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] Fwd: creating widget for Qt
Hello Ivan i shall try to elaborate the way i implemented that and your feedback is most welcome on that. 1. Separated the following files from the osgviewerQT example. AdapterWidget.h AdapterWidget.cpp ViewerQT.h And promoted the widget to the ViewerQT.h Loading the widget in the mainwindow and can load different model. And i did not recieve any warning so far. Yo said that you are having that while paint event(), Where are you exactly having that paint event() ? Did you mean that in the AdapterWidget that is the subclass of GLWidget?

Hello Ivan, In the pro file do i have to include OpenGL module or just the library linker for Openscenegraph will suffice Regards Sajjad -- Forwarded message -- From: Iván Date: Wed, Mar 4, 2009 at 11:27 PM Subject: Re: [osg-users] creating widget for Qt To: osg-users@lists.openscenegraph.org 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 mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
