This example demonstrates the usage of a tree view.
The Dir View example shows a tree view of the local file system. It uses the QFileSystemModel class to provide file and directory information.
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()
The example supports a number of command line options. These options include:
QFileSystemModel model; model.setRootPath(""); if (parser.isSet(dontUseCustomDirectoryIconsOption)) model.iconProvider()->setOptions(QFileIconProvider::DontUseCustomDirectoryIcons); QTreeView tree; tree.setModel(&model);
Declares model
as data model for reading the local filesystem. model.setRootPath("")
sets the current folder as the folder from which model
will start reading. QTreeView object tree
visualizes the filesystem in a tree structure.
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 layout options for animation, indentation, sorting, and sizing of the filesystem tree.
