[osg-users] I want to use "VncClient"

[Jianfeng Zhang]

Hi all,

I download a file just like:

#include <osgWidget/VncClient>
#include <osgViewer/Viewer>
#include <osgViewer/ViewerEventHandlers>
class EscapeHandler : public osgGA::GUIEventHandler
{
    public:
        EscapeHandler() {}

        bool handle(const osgGA::GUIEventAdapter&
ea,osgGA::GUIActionAdapter& aa)
        {
            if (ea.getHandled()) return false;

            switch(ea.getEventType())
            {
                case(osgGA::GUIEventAdapter::KEYUP):
                {
                    if (ea.getKey()==osgGA::GUIEventAdapter::KEY_Escape)
                    {
                        osgViewer::View* view =
dynamic_cast<osgViewer::View*>(&aa);
                        if (view) view->getViewerBase()->setDone(true);

                        return true;
                    }
                }

                default:
                    return false;
            }
            return false;
        }
};

int main(int argc,char** argv)
{
    osg::ArgumentParser arguments(&argc, argv);
    osgViewer::Viewer viewer(arguments);

    osgWidget::GeometryHints hints(osg::Vec3(0.0f,0.0f,0.0f),
                                   osg::Vec3(1.0f,0.0f,0.0f),
                                   osg::Vec3(0.0f,0.0f,1.0f),
                                   osg::Vec4(1.0f,1.0f,1.0f,1.0f),

osgWidget::GeometryHints::RESIZE_HEIGHT_TO_MAINTAINCE_ASPECT_RATIO);

    osg::ref_ptr<osg::Group> group = new osg::Group;

    for(int i=1; i<arguments.argc(); ++i)
    {
        if (!arguments.isOption(i))
        {
            osg::ref_ptr<osgWidget::VncClient> vncClient = new
osgWidget::VncClient;
            if (vncClient->connect(arguments[i], hints))
            {
                group->addChild(vncClient.get());

                hints.position.x() += 1.1f;
            }
        }
    }

    viewer.setSceneData(group.get());

    viewer.addEventHandler(new osgViewer::StatsHandler);

    // add a custom escape handler, but disable the standard viewer one to
enable the vnc images to handle
    // the escape without it getting caught by the viewer.
    viewer.addEventHandler(new EscapeHandler);
    viewer.setKeyEventSetsDone(0);

    return viewer.run();
}


Then ,I use command "g++ osgv.cpp -o osgv -losg -lvncclient -lvncserver
-losg -losgViewer -losgWidget"

./osgv 127.0.0.1:0

output Warning: Could not find plugin to read objects from file "127.0.0.1:
insecure.vnc".

How can I connect vnc?

Thanks very much
