NAME <\/a> <\/h2>\n

ttk::treeview \u2212 hierarchical multicolumn data display widget<\/p>\n

SYNOPSIS <\/a> <\/h2>\n

ttk::treeview<\/b> pathname<\/i> ?options<\/i>? ______________________________________________________________________________<\/p>\n

DESCRIPTION <\/a> <\/h2>\n

The ttk::treeview<\/b> widget displays a hierarchical collection of items. Each item has a textual label, an optional image, and an optional list of data values. The data values are displayed in successive columns after the tree label.<\/p>\n

The order in which data values are displayed may be controlled by setting the \u2212displaycolumns<\/b> widget option. The tree widget can also display column headings. Columns may be accessed by number or by symbolic names listed in the \u2212columns<\/b> widget option; see COLUMN IDENTIFIERS<\/b>.<\/p>\n

Each item is identified by a unique name. The widget will generate item IDs if they are not supplied by the caller. There is a distinguished root item, named {}<\/b>. The root item itself is not displayed; its children appear at the top level of the hierarchy.<\/p>\n

Each item also has a list of tags<\/i>, which can be used to associate event bindings with individual items and control the appearance of the item.<\/p>\n

Treeview widgets support horizontal and vertical scrolling with the standard \u2212<\/b>[xy<\/b>]scrollcommand<\/b> options and [xy<\/b>]view<\/b> widget commands.<\/p>\n

pathname<\/i> cget<\/b> option<\/i><\/p>\n

Returns the current value of the specified option<\/i>; see ttk::widget(n)<\/i>.<\/p>\n

pathname<\/i> children<\/b> item<\/i> ?newchildren<\/i>?<\/p>\n

If newchildren<\/i> is not specified, returns the list of children belonging to item<\/i>.<\/p>\n

If newchildren<\/i> is specified, replaces item<\/i>\u2019s child list with newchildren<\/i>. Items in the old child list not present in the new child list are detached from the tree. None of the items in newchildren<\/i> may be an ancestor of item<\/i>.<\/p>\n

pathname<\/i> column<\/b> column<\/i> ?\u2212option<\/i> ?value \u2212option value…<\/i>?<\/p>\n

If a single \u2212option<\/i> is specified, returns the value of that option. Otherwise, the options are updated with the specified values. The following options may be set on each column:
\u2212id<\/b> name<\/i><\/p>\n

The column name. This is a read-only option. For example, [$pathname<\/i> column #<\/b>n<\/i> \u2212id<\/b>] returns the data column associated with display column #n<\/i>.<\/p>\n

\u2212anchor<\/b> anchor<\/i><\/p>\n

Specifies how the text in this column should be aligned with respect to the cell. Anchor<\/i> is one of n<\/b>, ne<\/b>, e<\/b>, se<\/b>, s<\/b>, sw<\/b>, w<\/b>, nw<\/b>, or center<\/b>.<\/p>\n

\u2212minwidth<\/b> minwidth<\/i><\/p>\n

The minimum width of the column in pixels. The treeview widget will not make the column any smaller than \u2212minwidth<\/b> when the widget is resized or the user drags a column separator. Default is 20 pixels.<\/p>\n

\u2212stretch<\/b> boolean<\/i><\/p>\n

Specifies whether or not the column width should be adjusted when the widget is resized or the user drags a column separator. Boolean<\/i> may have any of the forms accepted by Tcl_GetBoolean<\/b>. By default columns are stretchable.<\/p>\n

\u2212width<\/b> width<\/i><\/p>\n

The width of the column in pixels. Default is 200 pixels. The specified column width may be changed by Tk in order to honor \u2212stretch<\/b> and\/or \u2212minwidth<\/b>, or when the widget is resized or the user drags a column separator.<\/p>\n

Use pathname column #0<\/i> to configure the tree column.<\/p>\n

pathname<\/i> configure<\/b> ?option<\/i>? ?value option value …<\/i>?<\/p>\n

Modify or query widget options; see ttk::widget(n)<\/i>.<\/p>\n

The items and all of their descendants are still present and may be reinserted at another point in the tree with the move<\/b> operation, but will not be displayed until that is done. The root item may not be detached. See also: delete<\/b>.<\/p>\n

pathname<\/i> exists<\/b> item<\/i><\/p>\n

Returns 1 if the specified item<\/i> is present in the tree, 0 otherwise.<\/p>\n

pathname<\/i> focus<\/b> ?item<\/i>?<\/p>\n

If item<\/i> is specified, sets the focus item to item<\/i>. Otherwise, returns the current focus item, or {}<\/b> if there is none.<\/p>\n

pathname<\/i> index<\/b> item<\/i><\/p>\n

Returns the integer index of item<\/i> within its parent\u2019s list of children.<\/p>\n

pathname<\/i> insert<\/b> parent index<\/i> ?\u2212id<\/b> id<\/i>? options…<\/i><\/p>\n

Creates a new item. parent<\/i> is the item ID of the parent item, or the empty string {}<\/b> to create a new top-level item. index<\/i> is an integer, or the value end<\/b>, specifying where in the list of parent<\/i>\u2019s children to insert the new item. If index<\/i> is less than or equal to zero, the new node is inserted at the beginning; if index<\/i> is greater than or equal to the current number of children, it is inserted at the end. If \u2212id<\/b> is specified, it is used as the item identifier; id<\/i> must not already exist in the tree. Otherwise, a new unique identifier is generated.<\/p>\n

pathname<\/i> insert<\/b> returns the item identifier of the newly created item. See ITEM OPTIONS<\/b> for the list of available options.<\/p>\n

Query or modify the options for the specified item<\/i>. If no \u2212option<\/i> is specified, returns a dictionary of option\/value pairs. If a single \u2212option<\/i> is specified, returns the value of that option. Otherwise, the item\u2019s options are updated with the specified values. See ITEM OPTIONS<\/b> for the list of available options.<\/p>\n

pathname<\/i> move<\/b> item parent index<\/i><\/p>\n

Moves item<\/i> to position index<\/i> in parent<\/i>\u2019s list of children. It is illegal to move an item under one of its descendants.<\/p>\n

If index<\/i> is less than or equal to zero, item<\/i> is moved to the beginning; if greater than or equal to the number of children, it is moved to the end.<\/p>\n

pathname<\/i> next<\/b> item<\/i><\/p>\n

Returns the identifier of item<\/i>\u2019s next sibling, or {}<\/b> if item<\/i> is the last child of its parent.<\/p>\n

pathName<\/i> tag bind<\/b> tagName<\/i> ?sequence<\/i>? ?script<\/i>?<\/p>\n

Add a Tk binding script for the event sequence sequence<\/i> to the tag tagName<\/i>. When an X event is delivered to an item, binding scripts for each of the item\u2019s \u2212tags<\/b> are evaluated in order as per bindtags(n)<\/i>.<\/p>\n

<\/b>, <\/b>, and virtual events are sent to the focus item. <\/b>, <\/b>, and <\/b> events are sent to the item under the mouse pointer. No other event types are supported.<\/p>\n

The binding script<\/i> undergoes %<\/b>-substitutions before evaluation; see bind(n)<\/b> for details.<\/p>\n

pathName<\/i> tag configure<\/b> tagName<\/i> ?option<\/i>? ?value option value…<\/i>?<\/p>\n

Query or modify the options for the specified tagName<\/i>. If one or more option\/value<\/i> pairs are specified, sets the value of those options for the specified tag. If a single option<\/i> is specified, returns the value of that option (or the empty string if the option has not been specified for tagName<\/i>). With no additional arguments, returns a dictionary of the option settings for tagName<\/i>. See TAG OPTIONS<\/b> for the list of available options.<\/p>\n

pathName<\/i> tag has<\/b> tagName<\/i> ?item<\/i>?<\/p>\n

If item<\/i> is specified, returns 1 or 0 depending on whether the specified item has the named tag. Otherwise, returns a list of all items which have the specified tag.<\/p>\n

The \u2212rowheight<\/b> value is not corrected by the tk scaling<\/b> value or by the configured font size and must always be set. Also make sure that the \u2212rowheight<\/b> is large enough to contain any images.<\/p>\n

To adjust the \u2212rowheight<\/b> for the Treeview style, use the following code after tk scaling<\/b> has been applied. Note that even if you do not support or change tk scaling<\/b> in your program, your users may have it set in their .wishrc.<\/p>\n
