-default#
Database namedefault
Database classDefault

May be set to one of normal, active, or disabled. In a dialog box, one button may be designated the “default” button (meaning, roughly, “the one that gets invoked when the user presses <Enter>”). active indicates that this is currently the default button; normal means that it may become the default button, and disabled means that it is not defaultable. The default is normal.

Depending on the theme, the default button may be displayed with an extra highlight ring, or with a different border color.

Widget command#

In addition to the standard cget, configure, identify element, instate, state and style commands (see ttk::widget), button widgets support the following additional commands:

pathName invoke

Invokes the command associated with the button.

Standard styles#

Ttk::button widgets support the Toolbutton style in all standard themes, which is useful for creating widgets for toolbars.

In the Aqua theme there are several other styles which can be used to produce replicas of many of the different button types that are discussed in Apple's Human Interface Guidelines. These include DisclosureButton, DisclosureTriangle, HelpButton, ImageButton, InlineButton, GradientButton, RoundedRectButton, and RecessedButton.

Styling options#

The class name for a ttk::button is TButton.

Dynamic states: active, disabled, pressed, readonly.

TButton styling options configurable with ttk::style are:

-anchor anchor
-background color
-bordercolor color
-compound compound
-darkcolor color
-foreground color
-font font
-highlightcolor color
-highlightthickness amount
-lightcolor color
-padding padding
-relief relief
-shiftrelief amount

-shiftrelief specifies how far the button contents are shifted down and right in the pressed state. This action provides additional skeuomorphic feedback.

-width amount

Some options are only available for specific themes.

See the ttk::style manual page for information on how to configure ttk styles.
