示例1: ParseFile
DataList ParseFile(QString const& fileName)
{
DataList dataList;
QFileInfo info(fileName);
if (info.exists()) {
try {
// First, check for a QChem input/output file. For input files
// OB returns an empty molecule, for output files the charge and
// multiplicity don't seem to be parsed correctly.
if (fileName.endsWith(".in", Qt::CaseInsensitive) ||
fileName.endsWith(".inp", Qt::CaseInsensitive) ||
fileName.endsWith(".qcin", Qt::CaseInsensitive) ||
fileName.endsWith(".qcinp", Qt::CaseInsensitive) ||
fileName.endsWith(".out", Qt::CaseInsensitive) ||
fileName.endsWith(".qcout", Qt::CaseInsensitive) ) {
QChem qchemParser;
dataList += qchemParser.parseFile(fileName);
}
// Second, check for external charges, which are not recognized by Open
// Babel. Check the ExternalChargesParser.h file for a description of
// the external charges format.
if (dataList.isEmpty()) {
ExternalCharges chargeParser;
dataList += chargeParser.parseFile(fileName);
}
// Now let Open Babel have a crack.
OpenBabel obParser;
dataList += obParser.parseFile(fileName);
// OB will pull the geometry from a FChk file, but not the MO
// information so we must pass this information explicitly.
if (fileName.endsWith(".fchk", Qt::CaseInsensitive)) {
FormattedCheckpoint fchkParser;
dataList += fchkParser.parseFile(fileName);
}
// Finally, if we have found anything we append the file as well.
if (!dataList.isEmpty()) {
Layer::Files* files(new Layer::Files());
files->appendLayer(new Layer::File(fileName));
dataList.append(files);
}
} catch (IOError& ioerr) {
if (Base::s_displayErrors) QMsgBox::warning(0, "IQmol", ioerr.what());
} catch (std::exception& e) {
if (Base::s_displayErrors) QMsgBox::warning(0, "IQmol", e.what());
}
}
return dataList;
