Hi, I'm using OSG & Qt to build a visualizer for my thesis. I'm completely new
to OSG and almost as new to Computer Graphics Programming too, so please don't
mad on me and be patient ;-)
I need to know how to get the list of supported file formats in order to use
QFileDialog with the proper extension filters. I'm trying this in a slot of my
main window:
Code:
void MainWindow::loadFile()
{
osg::ref_ptr<osgDB::Registry> registry = osgDB::Registry::instance();
osgDB::Registry::ReaderWriterList readers = registry->getReaderWriterList();
osgDB::Registry::ReaderWriterList::iterator it;
osgDB::ReaderWriter::FormatDescriptionMap descrMap;
osgDB::ReaderWriter::FormatDescriptionMap::iterator descrMapIt;
qDebug() << readers.size() << " registered ReaderWriters";
for (it = readers.begin(); it != readers.end(); it++) {
descrMap = (*it)->supportedOptions();
for( descrMapIt = descrMap.begin(); descrMapIt != descrMap.end();
descrMapIt++) {
//std::cout << (*descrMapIt);
}
}
QString filename = QFileDialog::getOpenFileName(
this, tr("Load a File:"),
QDir::homePath(), "OpenSceneGraph (*.osg)"
);
if ( !filename.isNull() ) {
this->osgWidget->loadModel(filename);
}
}
But qDebug() always says that there are no registered ReaderWriters. I'd expect
to get the native osg ReaderWriter as a minimum, but I can't get that even.
Thank you!
Cheers,
Daniel :D :D :? :( :( [/code]
