Description

A gtk.TreeView widget is used to display the contents of any model implementing the gtk.TreeModel interface. The tree models provided standard with GTK+ and PyGTK are:

In addition, PyGTK provides gtk.GenericTreeModel that allows you to create your own tree model entirely in Python.

The gtk.TreeView uses columns and cell renderers to actually display the model information. GTK+ and PyGTK provides the gtk.TreeViewColumn to manage the display of a column and the following cell renderers:

In addition, PyGTK provides the gtk.GenericCellRenderer that allows you to create your own cell renderers entirely in Python.

Constructor

    gtk.TreeView(model=None)

model :

the tree model to display

Returns :

A new gtk.TreeView widget.

Creates a new gtk.TreeView widget displaying the model specified by model.

Methods

gtk.TreeView.get_model

    def get_model()

Returns :

the current gtk.TreeModel, or None if none is currently being used.

The get_model() method returns the value of the "model" property containing the model the gtk.TreeView is displaying or None there is no the model.

gtk.TreeView.set_model

    def set_model(model=None)

model :

the new tree model to use with the treeview

The set_model() method sets the "model" property for the treeview to the value of model. If the treeview already has a model set, this method will remove it before setting the new model. If model is None, it will unset the old model.

gtk.TreeView.get_selection

    def get_selection()

Returns :

A gtk.TreeSelection object.

The get_selection() method returns the current gtk.TreeSelection associated with the treeview.

gtk.TreeView.get_hadjustment

    def get_hadjustment()

Returns :

a gtk.Adjustment object, or None if none is currently being used.

The get_hadjustment() method returns the value of the "hadjustment" property that contains the current horizontal gtk.Adjustment object or None (if no horizontal adjustment is being used).

gtk.TreeView.set_hadjustment

    def set_hadjustment(adjustment)

adjustment :

the gtk.Adjustment to set

The set_hadjustment() method sets the "hadjustment" property to the value of adjustment that must be a gtk.Adjustment object.

gtk.TreeView.get_vadjustment

    def get_vadjustment()

Returns :

a gtk.Adjustment object, or None if none is currently being used.

The get_vadjustment() method returns the value of the "vadjustment" property that contains the horizontal gtk.Adjustment or None if there is no vertical adjustment.

gtk.TreeView.set_vadjustment

    def set_vadjustment(adjustment)

adjustment :

the gtk.Adjustment to set

The set_vadjustment() method sets the "vadjustment" property to the value of adjustment. The new gtk.Adjustment replaces the current vertical adjustment.

gtk.TreeView.get_headers_visible

    def get_headers_visible()

Returns :

True if the headers are visible.

The get_headers_visible() method returns the value of the "headers-visible" property. If "headers-visible" is True the headers on the treeview are visible.

gtk.TreeView.set_headers_visible

    def set_headers_visible(headers_visible)

headers_visible :

if True the headers are visible

The set_headers_visible() method sets the "headers-visible" property to the value of headers_visible. If headers_visible is True the headers will be displayed.

gtk.TreeView.columns_autosize

    def columns_autosize()

The columns_autosize() method resizes all columns to their optimal width. Only works after the treeview has been realized.

gtk.TreeView.set_headers_clickable

    def set_headers_clickable(active)

active :

if True the headers are clickable

The set_headers_clickable() method sets the "headers-clickable" property to the value of active. If active is True the column title buttons can be clicked.

gtk.TreeView.set_rules_hint

    def set_rules_hint(setting)

setting :

if True the tree requires reading across rows

The set_rules_hint() method sets the "rules-hint" property to the value of setting. If setting is True it indicates that the user interface for your application requires users to read across tree rows and associate cells with one another. By default, the tree will be rendered with alternating row colors. Do not use it just because you prefer the appearance of the ruled tree; that's a question for the theme. Some themes will draw tree rows in alternating colors even when rules are turned off, and users who prefer that appearance all the time can choose those themes. You should call this method only as a semantic hint to the theme engine that your tree makes alternating colors useful from a functional standpoint (since it has lots of columns, generally).

gtk.TreeView.get_rules_hint

    def get_rules_hint()

Returns :

True if rules are useful for the user of this tree

The get_rules_hint() returns the value of the "rules-hint" property. See the set_rules_hint() method for more information on the use of "rules-hint".

gtk.TreeView.append_column

    def append_column(column)

column :

the gtk.TreeViewColumn to add.

Returns :

the number of columns in tree_view after appending.

The append_column() method appends the specified column to the list of columns and returns the new number of columns in the treeview.

gtk.TreeView.remove_column

    def remove_column(column)

column :

the gtk.TreeViewColumn to remove.

Returns :

the number of columns in the treeview after the column removal.

The remove_column() method removes the specified column from the treeview.

gtk.TreeView.insert_column

    def insert_column(column, position)

column :

the gtk.TreeViewColumn to be inserted.

position :

the position to insert column.

Returns :

the number of columns in the treeview after the insertion.

The insert_column() method inserts the specified column into the treeview at the location specified by position. If position is -1, then the column is inserted at the end.

gtk.TreeView.insert_column_with_attributes

    def insert_column_with_attributes(position, title, cell, ...)

position :

the position to insert the new column in.

title :

the title to set the header to.

cell :

the gtk.CellRenderer.

... :

optional keyword-value arguments

Returns :

the gtk.TreeViewColumn that was inserted.

The insert_column_with_attributes() method creates a new gtk.TreeViewColumn and inserts it into the treeview at the location specified by position with the column title specified by title and using the gtk.CellRenderer specified by cell. If position is -1, then the newly created column is inserted at the end. The column is initialized with the optional attributes passed as keyword-value pairs (e.g. text=0, foreground=2). See the gtk.TreeViewColumn.add_attribute() method for more information.

gtk.TreeView.insert_column_with_data_func

    def insert_column_with_data_func(position, title, cell, func, data=None)

position :

the position to insert, -1 for append

title :

the column title

cell :

a cell renderer for the column

func :

the function or method to set attributes of the cell renderer

data :

the data to pass with func

Returns :

the number of columns in the treeview after the insertion

The insert_column_with_data_func() method is a convenience function that inserts a new column into the treeview at the location specified by position with the specified title and the cell renderer specified by cell and using the function or method specified by func to set cell renderer attributes (normally using data from the model). The signature of func is:

    def celldatafunction(column, cell, model, iter, user_data)
def celldatamethod(self, column, cell, model, iter, user_data)

where column is the gtk.TreeViewColumn in the treeview, cell is the gtk.CellRenderer for column, model is the gtk.TreeModel for the treeview and iter is the gtk.TreeIter pointing at the row. See the gtk.TreeViewColumn.set_cell_data_func() and gtk.TreeViewColumn.pack_start() methods for more detail.

gtk.TreeView.get_column

    def get_column(n)

n :

the position of the column, counting from 0.

Returns :

the gtk.TreeViewColumn, or None if the position is outside the range of columns.

The get_column() method returns the gtk.TreeViewColumn at the specified position in the treeview.

gtk.TreeView.get_columns

    def get_columns()

Returns :

a list of gtk.TreeViewColumn s

The get_columns() method returns a list of all the gtk.TreeViewColumn objects currently in the treeview.

gtk.TreeView.move_column_after

    def move_column_after(column, base_column)

column :

the gtk.TreeViewColumn to be moved.

base_column :

the gtk.TreeViewColumn column is to be after, or None.

The move_column_after() method moves the gtk.TreeViewColumn specified by column to be after the treeview column specified by base_column. If base_column is None, then column is placed in the first position.

gtk.TreeView.set_expander_column

    def set_expander_column(column)

column :

the column to draw the expander arrow at orNone.

The set_expander_column() method sets the "expander-column" property to the value of column which must be a gtk.TreeViewColumn in the treeview. If column is None, then the expander arrow is always at the first visible column.

gtk.TreeView.get_expander_column

    def get_expander_column()

Returns :

the expander column.

The get_expander_column() method returns the value of the "expander-column" property that contains the current expander column i.e. the column that has the expander arrow drawn next to it.

gtk.TreeView.set_column_drag_function

    def set_column_drag_function(func, user_data)

func :

A function to determine which columns are reorderable, or None.

user_data :

User data to be passed to func, or None

Note

This method is available in PyGTK 2.4 and above.

The set_column_drag_function() method sets the user function specified by func for determining where a column may be dropped when dragged. The user function is called on every column pair in turn at the beginning of a column drag to determine where a drop can take place. The signature of func is:

  def func(tree_view, column, prev_column, next_column, data)

where tree_view is the gtk.TreeView, column is the gtk.TreeViewColumn being dragged, prev_column and next_column are the two gtk.TreeViewColumn objects bracketing the drop spot, and data is user_data. If prev_column or next_column is None, then the drop is at an edge. If func is None, the user drag function is removed and the gtk.TreeView reverts to the default behavior of allowing any reorderable column to be dropped anywhere.

gtk.TreeView.scroll_to_point

    def scroll_to_point(tree_x, tree_y)

tree_x :

the X coordinate of new top-left pixel of visible area, or -1

tree_y :

the Y coordinate of new top-left pixel of visible area, or -1

The scroll_to_point() method scrolls the treeview so that the top-left corner of the visible area is at the location specified by tree_x and tree_y, where tree_x and tree_y are specified in tree window coordinates. The treeview must be realized before this method is called. If it isn't, you should use the scroll_to_cell() method instead. If either tree_x or tree_y are -1, there is no scrolling in that direction.

gtk.TreeView.scroll_to_cell

    def scroll_to_cell(path, column=None, use_align=False, row_align=0.0, col_align=0.0)

path :

the path of the row to move to

column :

the gtk.TreeViewColumn to move horizontally to, or None.

use_align :

if True use the alignment arguments

row_align :

the vertical alignment of the row specified by path.

col_align :

the horizontal alignment of the column specified by column.

The scroll_to_cell() method scrolls the treeview display to the position specified by column and path. If column is None, no horizontal scrolling occurs. The alignment parameters specified by row_align and col_align determines where column is placed within the treeview. The values of col_align and row_align range from 0.0 to 1.0. The alignment values specify the fraction of display space that is to the left of or above the cell. If use_align is False, the alignment arguments are ignored, and the tree does the minimum amount of work to scroll the cell onto the screen. This means that the cell will be scrolled to the edge closest to it's current position. If the cell is currently visible on the screen, nothing is done. This method only works if the model is set, and path is a valid row in the model.

gtk.TreeView.row_activated

    def row_activated(path, column)

path :

the tree path of the row of the cell to be activated.

column :

the gtk.TreeViewColumn of the cell to be activated.

The row_activated() method activates the cell determined by path and column.

gtk.TreeView.expand_all

    def expand_all()

The expand_all() method recursively expands all nodes in the treeview.

gtk.TreeView.collapse_all

    def collapse_all()

The collapse_all() method recursively collapses all visible, expanded nodes in the treeview.

gtk.TreeView.expand_to_path

    def expand_to_path(path)

path :

a path to a row.

Note

This method is available in PyGTK 2.2 and above.

The expand_to_row() method expands the row with the tree path specified by path. This will also expand all parent rows of path as necessary.

gtk.TreeView.expand_row

    def expand_row(path, open_all)

path :

the path to a row

open_all :

if True recursively expand, otherwise just expand immediate children

The expand_row() method opens the row specified by path so its children are visible. If open_all is True all rows are expanded, otherwise only the immediate children of path are expanded.

gtk.TreeView.collapse_row

    def collapse_row(path)

path :

the path to a row

The collapse_row() method collapses the row specified by path (hides its child rows, if they exist).

gtk.TreeView.map_expanded_rows

    def map_expanded_rows(func, data)

func :

A function to be called

data :

User data to be passed to the function.

Note

This method is available in PyGTK 2.2 and above.

The map_expanded_rows() method calls the function specified by func on all expanded rows passing data as an argument.

gtk.TreeView.row_expanded

    def row_expanded(path)

path :

the path to a row to test the expansion state.

Returns :

True if path is expanded.

The row_expanded() method returns True if the node pointed to by path is expanded.

gtk.TreeView.set_reorderable

    def set_reorderable(reorderable)

reorderable :

if True, the tree can be reordered.

The set_reorderable() method sets the "reorderable" property to the value of reorderable. This method is a convenience method to allow you to reorder models that support the gtk.TreeDragSource and the gtk.TreeDragDest interfaces. Both gtk.TreeStore and gtk.ListStore support these. If reorderable is True, then the user can reorder the model by dragging and dropping rows. The application can listen to these changes by connecting to the model's signals.

Note

This function does not give you any degree of control over the order -- any reordering is allowed. If more control is needed, you should probably handle drag and drop manually.

gtk.TreeView.get_reorderable

    def get_reorderable()

Returns :

True if the tree can be reordered.

The get_reorderable() method returns the value of the "reorderable" property that determines if the user can reorder the tree via drag-and-drop. See the set_reorderable() method for more information.

gtk.TreeView.set_cursor

    def set_cursor(path, focus_column=None, start_editing=False)

path :

a tree path

focus_column :

a gtk.TreeViewColumn, or None

start_editing :

if True the specified cell should start being edited.

The set_cursor() method sets the current keyboard focus to be at the row specified by path, and selects it. This is useful when you want to focus the user's attention on a particular row. If column is not None, then focus is given to the specified column. Additionally, if column is specified, and start_editing is True, then editing should be started in the specified cell. This method is often followed by the gtk.Widget.grab_focus() method to give keyboard focus to the treeview. Please note that editing can only happen when the widget is realized.

gtk.TreeView.set_cursor_on_cell

    def set_cursor_on_cell(path, focus_column=None, focus_cell=None, start_editing=False)

path :

a tree path

focus_column :

a gtk.TreeViewColumn, or None

focus_cell :

a gtk.CellRenderer, or None

start_editing :

True if the specified cell should start being edited.

Note

This method is available in PyGTK 2.2 and above.

The set_cursor_on_cell() method sets the current keyboard focus to be at the node specified by path, and selects it. This is useful when you want to focus the user's attention on a particular row. If focus_column is specified, focus is given to that column. If focus_column and focus_cell are specified, and focus_column contains 2 or more editable or activatable cells, then focus is given to the cell specified by focus_cell. Additionally, if focus_column is specified, and start_editing is True, editing should be started in the specified cell. This method is often followed by the gtk.Widget.grab_focus() method in order to give keyboard focus to the widget. Please note that editing can only happen when the widget is realized.

gtk.TreeView.get_cursor

    def get_cursor()

Returns :

a tuple containing the current cursor path and focus column.

The get_cursor() method returns a tuple containing the current path and focus column. If the cursor isn't currently set, the current path will be None. If no column currently has focus, the current focus column will be None.

gtk.TreeView.get_bin_window

    def get_bin_window()

Returns :

a gtk.gdk.Window, or None

The get_bin_window() method returns the window that the treeview renders to or None if the treeview is not realized yet. This is used primarily to compare to the event.window attribute to confirm that the event on the treeview is on the right window.

gtk.TreeView.get_path_at_pos

    def get_path_at_pos(x, y)

x :

The x position to be identified.

y :

The y position to be identified.

Returns :

a tuple containing: a tree path; a gtk.TreeViewColumn object; the X coordinate relative to the cell; and, the Y coordinate relative to the cell. If there is no path at the position None is returned.

The get_path_at_pos() method returns a tuple containing:

  • the path at the specified point (x, y), relative to widget coordinates
  • the gtk.TreeViewColumn at that point
  • the X coordinate relative to the cell background
  • the Y coordinate relative to the cell background

x and y are relative to the coordinates of an event on the treeview only when event.window==treeview.get_bin_window(). It is primarily used for popup menus. This method is only meaningful if the treeview is realized. This method returns None if there is no path at the position.

gtk.TreeView.get_cell_area

    def get_cell_area(path, column)

path :

a tree path for the row

column :

a gtk.TreeViewColumn for the column

Returns :

rectangle

The get_cell_area() method returns the bounding gtk.gdk.Rectangle in tree window coordinates for the cell at the row specified by path and the column specified by column. If path points to a path not currently displayed, the y and height attributes of the rectangle will be 0. The sum of all cell rects does not cover the entire tree; there are extra pixels in between rows, for example. The returned rectangle is equivalent to the cell_area passed to the gtk.CellRenderer.render() method. This method is only valid if the treeview is realized.

gtk.TreeView.get_background_area

    def get_background_area(path, column)

path :

a tree path for the row,

column :

a gtk.TreeViewColumn for the column

Returns :

a rectangle

The get_background_area() method returns the bounding gtk.gdk.Rectangle in tree window coordinates for the cell at the row specified by path and the column specified by column. If path points to a node not found in the tree, the y and height attributes of the rectangle will be 0. The returned rectangle is equivalent to the background_area passed to the gtk.CellRenderer.render(). These background areas tile to cover the entire tree window (except for the area used for header buttons). Contrast with the cell_area, returned by the get_cell_area() method, that returns only the cell itself, excluding the surrounding borders and the tree expander area.

gtk.TreeView.get_visible_rect

    def get_visible_rect()

Returns :
