Hallo!
I tried to create the OpenSG + QT example from the OpenSGStarterGuide and I
CAN RUN IT!!!!!! (after three weeks it was a very exciting moment for me!)
But after the first delight I tried the function of the button and it did
not work. The problem is, I can not load the scene file.
This is the code of the function, that is called, when the button is
clicked:
void MainForm::load()
{
QString s (QFileDialog::getOpenFileName(QString::null, "Szenenformate
(*.wrl)"));
if (!s.isEmpty())
{
char *filename;
filename = (char *)s.latin1();
NodePtr n = SceneFileHandler::the().read(filename);
//NodePtr n = SceneFileHandler::the().read("data/terrain.wrl");
if (n != NullFC)
osgWidget->getManager().setRoot(n);
else
osgWidget->getManager().setRoot(makeTorus(0.5, 2, 16, 16));
osgWidget->getManager().useOpenSGLogo();
osgWidget->getManager().showAll();
osgWidget->updateGL();
}
}
I found out, that it is possible to load the .wrl scene when I give the
SceneFileHandler a relativ path (you find it in the comment of the code).
But when I try to use the filename which I get from the FileDialog the
SceneFileHandler cannot open the scene and n is a NullFC.
Do someone know what's wrong. Is it perhaps a problem of the different
pathes under windows in equation to Linux (I run it under WindowsXP and use
VisualStudio.Net 2003)?
