Dir View Example
The Dir View example shows a tree view of the local file system. It uses the QFileSystemModel class to provide file and directory information.
The example supports a number of command line options. These options include:
- Application description
- -help option
- -version option
- if the optionc {-c} is specified, the application will not use custom directory options
QCommandLineParser parser; parser.setApplicationDescription("Qt Dir View Example"); parser.addHelpOption(); parser.addVersionOption(); QCommandLineOption dontUseCustomDirectoryIconsOption("c", "Set QFileIconProvider::DontUseCustomDirectoryIcons"); parser.addOption(dontUseCustomDirectoryIconsOption); parser.addPositionalArgument("directory", "The directory to start in."); parser.process(app); const QString rootPath = parser.positionalArguments().isEmpty()
Declares a QFileSystemModel as data model for viewing the local file system. QFileSystem works with a cache, that is, it is updated continually with QFileSystemWatcher on that folder.
QFileSystemModel model; model.setRootPath(""); if (parser.isSet(dontUseCustomDirectoryIconsOption)) model.iconProvider()->setOptions(QFileIconProvider::DontUseCustomDirectoryIcons); QTreeView tree; tree.setModel(&model);
Creates a model/view implementation called tree
for viewing the filesystem.
tree.setAnimated(false); tree.setIndentation(20); tree.setSortingEnabled(true); const QSize availableSize = QApplication::desktop()->availableGeometry(&tree).size(); tree.resize(availableSize / 2); tree.setColumnWidth(0, tree.width() / 3); tree.setWindowTitle(QObject::tr("Dir View"));
Sets some formatting options for tree
.
