43.5.1 Locked Text Fields
These classes and mixins provide text and combo field controls that cannot be
directly edited by the user, but may be updated by other controls.
This mixin updates text field classes to prevent user edits, but allow
programmatic update of the text value. It also sets the undo history length to
a default of 0, as user undo commands are disabled and the history takes up
space.
The mixin adds the undo-history initialization argument to control the
length of the undo history. It defaults to 0 to save space, but may be set
higher.
The mixin inherits all the initialization arguments of its parent class; it does
not override any of them.
Unlocks the text field’s nested editor, calls the parent class’s
set-value, and then re-locks the editor.
43.5.2 Union GUIs
This mixin modifies a container class to display only one of its child areas at
a time, but to leave room to switch to any of them.
This method changes which of the container’s children is displayed. The chosen
child is shown and the previous choice is hidden.
