There can be several Renderer in each TreeViewColumn. Each Renderer can reflect several Attributes from a ListStore or TreeStore.

treeViewColumnsAutosize

Resize the columns to their optimal size.

treeViewExpandAll

Expand all nodes in the TreeView.

treeViewExpandRow

Expand a row.

Expand a node that is specified by path. If the all is True every child will be expanded recursively. Returns True if the row existed and had children.

treeViewExpandToPath

Make a certain path visible.

This will expand all parent rows of tp as necessary.

Only available in Gtk 2.2 and higher.

treeViewGetColumn

Retrieve a TreeViewColumn.

Retrieve the pos th columns of TreeView. If the index is out of range Nothing is returned.

treeViewGetColumns

Return all TreeViewColumns in this TreeView.

treeViewGetCursor

Retrieves the position of the focus.

Returns a pair (path, column).If the cursor is not currently set, path will be Nothing. If no column is currently selected, column will be Nothing.

treeViewGetExpanderColumn

Get location of hierarchy controls.

Gets the column to draw the expander arrow at. If col is Nothing, then the expander arrow is always at the first visible column.

treeViewGetHadjustment

Get the Adjustment that represents the horizontal aspect.

treeViewGetHeadersVisible

Query if the column headers are visible.

treeViewGetModel

Retrieve the TreeModel that supplies the data for this TreeView. Returns Nothing if no model is currently set.

treeViewGetReorderable

Query if rows can be moved around.

See treeViewSetReorderable.

treeViewGetRulesHint

Give visual aid for wide columns.

This function tells GTK+ that the user interface for your application requires users to read across tree columns. By default, GTK+ will then render the tree 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 function 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).

treeViewGetSelection

Retrieve a TreeSelection that holds the current selected nodes of the View.

treeViewGetVadjustment

Get the Adjustment that represents the vertical aspect.

treeViewInsertColumn

Inserts column tvc into the TreeView widget at the position pos. Returns the number of columns after insertion. Specify -1 for pos to insert the column at the end.

treeViewInsertColumnWithAttributes

Insert new TreeViewColumn.

Inserts new column into the TreeView tv at position pos with title title, cell renderer cr and attributes attribs. Specify -1 for pos to insert the column at the end.

treeViewMapExpandedRows

Call function for every expaned row.

treeViewMoveColumnAfter

Move a specific column.

Use treeViewMoveColumnToFront if you want to move the column to the left end of the TreeView.

treeViewMoveColumnFirst

Move a specific column.

Use treeViewMoveColumnAfter if you want to move the column somewhere else than to the leftmost position.

treeViewRemoveColumn

Remove column tvc from the TreeView widget. The number of remaining columns is returned.

treeViewRowActivated

Emit the activated signal on a cell.

treeViewRowExpanded

Check if row is expanded.

treeViewScrollToCell

Scroll to a cell.

Scroll to a cell as specified by path and tvc. The cell is aligned within the TreeView widget as follows: horizontally by hor from left ( 0.0) to right ( 1.0) and vertically by ver from top ( 0.0) to buttom ( 1.0).

treeViewScrollToPoint

Scroll to a coordinate.

Scrolls the tree view such that the top-left corner of the visible area is treeX, treeY, where treeX and treeY are specified in tree window coordinates. The TreeView must be realized before this function is called. If it isn't, you probably want to use treeViewScrollToCell.

treeViewSetColumnDragFunction

Specify where a column may be dropped.

Sets a user function for determining where a column may be dropped when dragged. This 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 callback function take the TreeViewColumn to be moved, the second and third arguments are the columns on the left and right side of the new location. At most one of them might be Nothing which indicates that the column is about to be dropped at the left or right end of the TreeView.

The predicate pred should return True if it is ok to insert the column at this place.

Use Nothing for the predicate if columns can be inserted anywhere.

treeViewSetCursor

Selects a specific row.

Sets the current keyboard focus to be at path, and selects it. This is useful when you want to focus the user's attention on a particular row. If focusColumn is given, then the input focus is given to the column specified by it. Additionally, if focusColumn is specified, and startEditing is True, then editing will be started in the specified cell. This function is often followed by a widgetGrabFocus to the TreeView in order to give keyboard focus to the widget.

treeViewSetCursorOnCell

Selects a cell in a specific row.

Similar to treeViewSetCursor but allows a column to containt several CellRenderers.

Only available in Gtk 2.2 and higher.

treeViewSetExpanderColumn

Set location of hierarchy controls.

Sets the column to draw the expander arrow at. If col is Nothing, then the expander arrow is always at the first visible column.

treeViewSetHadjustment

Set the Adjustment that controls the horizontal aspect. If adj is Nothing then set no Adjustment widget.

treeViewSetHeadersClickable

Set wether the columns headers are sensitive to mouse clicks.

treeViewSetHeadersVisible

Set the visibility state of the column headers.

treeViewSetModel

Set the TreeModel for the current View.

treeViewSetReorderable

Check if rows can be moved around.

Set whether the user can use drag and drop (DND) to reorder the rows in the store. This works on both TreeStore and ListStore models. If ro is True, then the user can reorder the model by dragging and dropping rows. The developer can listen to these changes by connecting to the model's signals. This function does not give you any degree of control over the order -- any reorderering is allowed. If more control is needed, you should probably handle drag and drop manually.

treeViewSetRulesHint

Query if visual aid for wide columns is turned on.

treeViewSetVadjustment

Set the Adjustment that controls the vertical aspect. If adj is Nothing then set no Adjustment widget.
