ttk::widget - Standard options and commands supported by Tk themed widgets







This manual describes common widget options and commands.


The following options are supported by all Tk themed widgets:

Command-Line Name:-class
Database Name:undefined
Database Class:undefined

Specifies the window class. The class is used when querying the option database for the window’s other options, to determine the default bindtags for the window, and to select the widget’s default layout and style. This is a read-only option: it may only be specified when the window is created, and may not be changed with the configure widget command.

Command-Line Name:-cursor
Database Name:cursor
Database Class:Cursor

Specifies the mouse cursor to be used for the widget. See Tk_GetCursor and cursors(n) in the Tk reference manual for the legal values. If set to the empty string (the default), the cursor is inherited from the parent widget.

Command-Line Name:-takefocus
Database Name:takeFocus
Database Class:TakeFocus

Determines whether the window accepts the focus during keyboard traversal. Either 0, 1, a command prefix (to which the widget path is appended, and which should return 0 or 1), or the empty string. See options(n) in the Tk reference manual for the full description.

Command-Line Name:-style
Database Name:style
Database Class:Style

May be used to specify a custom widget style.


The following options are supported by widgets that are controllable by a scrollbar. See scrollbar(n) for more information

Command-Line Name:-xscrollcommand
Database Name:xScrollCommand
Database Class:ScrollCommand

A command prefix, used to communicate with horizontal scrollbars. When the view in the widget’s window changes, the widget will generate a Tcl command by concatenating the scroll command and two numbers. Each of the numbers is a fraction between 0 and 1 indicating a position in the document; 0 indicates the beginning, and 1 indicates the end. The first fraction indicates the first information in the widget that is visible in the window, and the second fraction indicates the information just after the last portion that is visible.

Typically the xScrollCommand option consists of the path name of a scrollbar widget followed by “set”, e.g. “.x.scrollbar set”. This will cause the scrollbar to be updated whenever the view in the window changes.

If this option is set to the empty string (the default), then no command will be executed.

Command-Line Name:-yscrollcommand
Database Name:yScrollCommand
Database Class:ScrollCommand

A command prefix, used to communicate with vertical scrollbars. See the description of -xscrollcommand above for details.


The following options are supported by labels, buttons, and other button-like widgets:

Command-Line Name:-text
Database Name:text
Database Class:Text

Specifies a text string to be displayed inside the widget (unless overridden by -textvariable).

Command-Line Name:-textvariable
Database Name:textVariable
Database Class:Variable

Specifies the name of variable whose value will be used in place of the -text resource.

Command-Line Name:-underline
Database Name:underline
Database Class:Underline

If set, specifies the integer index (0-based) of a character to underline in the text string. The underlined character is used for mnemonic activation.

Command-Line Name:-image
Database Name:image
Database Class:Image

Specifies an image to display. This is a list of 1 or more elements. The first element is the default image name. The rest of the list is a sequence of statespec / value pairs as per style map, specifying different images to use when the widget is in a particular state or combination of states. All images in the list should have the same size.

Command-Line Name:-compound
Database Name:compound
Database Class:Compound

Specifies how to display the image relative to the text, in the case both -text and -image are present. Valid values are:
text Display text only.
image Display image only.
center Display text centered on top of image.
right Display image above, below, left of, or right of the text, respectively.
none The default; display the image if present, otherwise the text.

Command-Line Name:-width
Database Name:width
Database Class:Width

If greater than zero, specifies how much space, in character widths, to allocate for the text label. If less than zero, specifies a minimum width. If zero or unspecified, the natural width of the text label is used.


Command-Line Name:-state
Database Name:state
Database Class:State

May be set to normal or disabled to control the disabled state bit. This is a write-only option: setting it changes the widget state, but the state widget command does not affect the -state option.


pathName cget option
  Returns the current value of the configuration option given by option.
pathName configure ?option? ?value option value ...?
  Query or modify the configuration options of the widget. If one or more option-value pairs are specified, then the command modifies the given widget option(s) to have the given value(s); in this case the command returns an empty string. If option is specified with no value, then the command returns a list describing the named option: the elements of the list are the option name, database name, database class, default value, and current value. If no option is specified, returns a list describing all of the available options for pathName.
pathName identify x y
  Returns the name of the element under the point given by x and y, or an empty string if the point does not lie within any element. x and y are pixel coordinates relative to the widget.
pathName instate statespec ?script?
  Test the widget’s state. If script is not specified, returns 1 if the widget state matches statespec and 0 otherwise. If script is specified, equivalent to

if {[pathName instate stateSpec]} script

pathName state ?stateSpec?
  Modify or inquire widget state. If stateSpec is present, sets the widget state: for each flag in stateSpec, sets the corresponding flag or clears it if prefixed by an exclamation point. Returns a new state spec indicating which flags were changed:

set changes [pathName state spec]
pathName state $changes

will restore pathName to the original state. If stateSpec is not specified, returns a list of the currently-enabled state flags.


The widget state is a bitmap of independent state flags. Widget state flags include:
active The mouse cursor is over the widget and pressing a mouse button will cause some action to occur. (aka “prelight” (Gnome), “hot” (Windows), “hover”).
  Widget is disabled under program control (aka “unavailable”, “inactive”)
focus Widget has keyboard focus
  Widget is being pressed (aka “armed” in Motif).
  “On”, “true”, or “current” for things like checkbuttons and radiobuttons.
  Windows and the Mac have a notion of an “active” or foreground window. The background state is set for widgets in a background window, and cleared for those in the foreground window.
  Widget should not allow user modification.
  A widget-specific alternate display format. For example, used for checkbuttons and radiobuttons in the “tristate” or “mixed” state, and for buttons with -default active.
  The widget’s value is invalid. (Potential uses: scale widget value out of bounds, entry widget value failed validation.)
A state specification or stateSpec is a list of state names, optionally prefixed with an exclamation point (!) indicating that the bit is off.


set b [ttk::button .b]

# Disable the widget: $b state disabled

# Invoke the widget only if it is currently pressed and enabled: $b instate {pressed !disabled} { .b invoke }

# Reenable widget: $b state !disabled
