Absolute file paths begin with the directory separator ('/') or a - drive specification (not applicable to UNIX). Relative file names begin - with a directory name or a file name and specify a path relative to the - current directory. - - An example of an absolute path is the string "/tmp/quartz", a relative - path might look like "src/fatlib". You can use the function isRelative() - to check if a QDir is using a relative or an absolute file path. You can - call the function convertToAbs() to convert a relative QDir to an - absolute one. - - The directory "example" under the current directory is checked for existence - in the example below: - - \code - QDir d( "example" ); // "./example" - if ( !d.exists() ) - qWarning( "Cannot find the example directory" ); - \endcode - - If you always use '/' as a directory separator, Qt will translate your - paths to conform to the underlying operating system. - - cd() and cdUp() can be used to navigate the directory tree. Note that the - logical cd and cdUp operations are not performed if the new directory does - not exist. - - Example: - \code - QDir d = QDir::root(); // "/" - if ( !d.cd("tmp") ) { // "/tmp" - qWarning( "Cannot find the \"/tmp\" directory" ); - } else { - QFile f( d.filePath("ex1.txt") ); // "/tmp/ex1.txt" - if ( !f.open(IO_ReadWrite) ) - qWarning( "Cannot create the file %s", f.name() ); - } - \endcode - - To read the contents of a directory you can use the entryList() and - entryInfoList() functions. - - Example: - \code - #include <stdio.h> - #include <qdir.h> - - // - // This program scans the current directory and lists all files - // that are not symbolic links, sorted by size with the smallest files - // first. - // - - int main( int argc, char **argv ) - { - QDir d; - d.setFilter( QDir::Files | QDir::Hidden | QDir::NoSymLinks ); - d.setSorting( QDir::Size | QDir::Reversed ); - - const QFileInfoList *list = d.entryInfoList(); - QFileInfoListIterator it( *list ); // create list iterator - QFileInfo *fi; // pointer for traversing - - printf( " BYTES FILENAME\n" ); // print header - while ( (fi=it.current()) ) { // for each file... - printf( "%10li %s\n", fi->size(), fi->fileName().data() ); - ++it; // goto next list element - } - } - \endcode -*/ - - -/*! - Constructs a QDir pointing to the current directory. - \sa currentDirPath() -*/ - -QDir::QDir() -{ - dPath = QString::fromLatin1("."); - init(); -} - -/*! - Constructs a QDir. - - \arg \e path is the directory. - \arg \e nameFilter is the file name filter. - \arg \e sortSpec is the sort specification, which describes how to - sort the files in the directory. - \arg \e filterSpec is the filter specification, which describes how - to filter the files in the directory. - - Most of these arguments (except \e path) have optional values. - - Example: - \code - // lists all files in /tmp - - QDir d( "/tmp" ); - for ( int i=0; i<d.count(); i++ ) - printf( "%s\n", d[i] ); - \endcode - - If \e path is "" or null, the directory is set to "."
