The QTreeWidget class provides a tree view that uses a predefined tree model.

PyQT5控件:树视图(QTreeWidget)

The QTreeWidget class is a convenience class that provides a standard tree widget with a classic item-based interface similar to that used by the QListView class in Qt 3. A more flexible approach involves combining a QTreeView with a standard item model. This allows the storage of data to be separated from its representation. Before items can be added to the tree widget, the number of columns must be set with setColumnCount. This allows each item to have one or more labels or other decorations.

The number of columns in use can be found with the columnCount function. The tree can have a header that contains a section for each column in the widget. It is easiest to set up the labels for each section by supplying a list of strings with setHeaderLabelsbut a custom header can be constructed with a QTreeWidgetItem and inserted into the tree with the setHeaderItem function.

The items in the tree can be sorted by column according to a predefined sort order. If sorting is enabled, the user can sort the items by clicking on a column header.

Sorting can be enabled or disabled by calling setSortingEnabled. The isSortingEnabled function indicates whether sorting is enabled.

See also columnCount and currentItem. Note: Since each item is removed from the tree widget before being deleted, the return value of QTreeWidgetItem::treeWidget will be invalid when called from an item's destructor. This function has no effect if no persistent editor is open for this combination of item and column. See also setCurrentItem and columnCount.

See also setCurrentItem and currentItemChanged. This signal is emitted when the current item changes.

Constructs a tree widget with the given parent. Appends the item as a top-level item in the widget. Appends the list of items as a top-level items in the widget. Closes the persistent editor for the item in the given column. This function has no effect if no persistent editor is open for this combination of item and column. Closes the item. Handles the data supplied by a drag and drop operation that ended with the given action in the index in the given parent item.

The default implementation returns true if the drop was successfully handled by decoding the mime data and inserting it into the model; otherwise it returns false.

Starts editing the item in the given column if it is editable.Here are the examples of the python api PyQt5.

Handles the data supplied by a drag and drop operation that ended with the given action in the index in the given parent item. The default implementation returns true if the drop was successfully handled by decoding the mime data and inserting it into the model; otherwise it returns false. Returns a list of items that match the given textusing the given flagsin the given column. Returns the QModelIndex assocated with the given item in the given column.

See also itemFromIndex and topLevelItem. See also sortItems and topLevelItemCount. See also addTopLevelItem and columnCount. The invisible root item provides access to the tree widget's top-level items through the QTreeWidgetItem API, making it possible to write functions that can treat top-level items and their children in a uniform way; for example, recursive functions.

Returns true if the given item is set to show only one section over all columns; otherwise returns false. See also setFirstItemColumnSpanned.

Returns a pointer to the item at the coordinates p. The coordinates are relative to the tree widget's viewport. Returns a pointer to the item at the coordinates xy.Tree widget items are used to hold rows of information for tree widgets.

Rows usually contain several columns of data, each of which can contain a text label and an icon. It provides an item for use with the QTreeWidget class. Items are usually constructed with a parent that is either a QTreeWidget for top-level items or a QTreeWidgetItem for items on lower levels of the tree. For example, the following code constructs a top-level item to represent cities of the world, and adds a entry for Oslo as a child item:.

Items can be added in a particular order by specifying the item they follow when they are constructed:. Each column in an item can have its own background brush which is set with the setBackground function. The current background brush can be found with background.

The text label for each column can be rendered with its own font and brush. These are specified with the setFont and setForeground functions, and read with font and foreground. The main difference between top-level items and those in lower levels of the tree is that a top-level item has no parent. This information can be used to tell the difference between items, and is useful to know when inserting and removing items from the tree. Children of an item can be removed with takeChild and inserted at a given index in the list of children with the insertChild function.

By default, items are enabled, selectable, checkable, and can be the source of a drag and drop operation. Each item's flags can be changed by calling setFlags with the appropriate value see Qt.

Checkable items can be checked and unchecked with the setCheckState function. The corresponding checkState function indicates whether the item is currently checked. When subclassing QTreeWidgetItem to provide custom items, it is possible to define new types for them so that they can be distinguished from standard items.

The constructors for subclasses that require this feature need to call the base class constructor with a new type value equal to or greater than UserType. You can define new user types in QTreeWidgetItem subclasses to ensure that custom items are treated specially; for example, when items are sorted.

Rows usually contain several columns of data, each of which can contain a text label and an icon. It provides an item for use with the PySide. QTreeWidget class. Items are usually constructed with a parent that is either a PySide.

QTreeWidget for top-level items or a PySide. QTreeWidgetItem for items on lower levels of the tree. For example, the following code constructs a top-level item to represent cities of the world, and adds a entry for Oslo as a child item:. Items can be added in a particular order by specifying the item they follow when they are constructed:. Each column in an item can have its own background brush which is set with the PySide.

The current background brush can be found with PySide. The text label for each column can be rendered with its own font and brush. These are specified with the PySide. The main difference between top-level items and those in lower levels of the tree is that a top-level item has no PySide. This information can be used to tell the difference between items, and is useful to know when inserting and removing items from the tree. Children of an item can be removed with PySide.

Checkable items can be checked and unchecked with the PySide.This tutorial covers individual item control, changing the look of your Widget, and signals. Tree widgets are tiny do-hickeys that grow under the brickberry branches beneath the bunions and basil bugites… and dogs hate them. Not really. First, Tree widgets can have items parented to other items and secondly, tree widgets have columns Tree widgets are called such because they are designed similar to tree data structure.

We then create one last item without a parent being passed into the arguments, set it to be disabled and add it to the tree widget. Note there are many other ways to construct widgets and widget items. These are just my favorite.
