ttkbootstrap applies a default style to legacy tkinter widgets so that they do
not look out-of-place when used with themed ttk widgets. The Text and Canvas
widgets are commonly used with themed ttk widgets for example.
To ensure the styles are updated when the theme is changed, each legacy widget
is registered with the Publisher which sends an update message to each legacy
widget when the theme is changed in order to initiate a theme configuration on
the widget.
While the theming functionality is appropriate in most cases, it also prevents
the user from making custom changes to the widget. However, in version 1.2 an
autostyle parameter was added to all legacy widgets. By default, autostyle
is implicitly True. This means, that ttkbootstrap will handle all of the
styling on legacy widgets. However, if you set the autostyle parameter to
False, the widget styling will be delegated to the user. This will enable
you to make custom changes to legacy widgets.
!!! warning "Turning off autostyle should be used with caution" If you turn off autostyle on a widget, it will no longer receive theme change updates; no styling will be applied by default, including fonts, relief, etc...
