NAME
Term::Fabulous::ThemeEditor::Preview - The gallery of widgets in the theme editor's preview
DESCRIPTION
Part of Term::Fabulous::ThemeEditor; not meant to be used on its own. A box with a scroll box of sections, one or more per widget family, each under a divider that names the families it shows: the palette (a swatch of every token), text and links, boxes, buttons, fields (text fields with a placeholder, a selection, an invalid value and a disabled one, a text area with a scrollbar), choices (check boxes, radio buttons, a segmented control, a slider, a star rating, a dropdown), a color picker with swatches, tabs, document tabs (with unsaved changes, errors and a tab that cannot be closed), an accordion, a table (groups, a filter row, pages), progress bars and a spinner, toasts (and a button that shows one), a menu bar whose titles open menus, a menu with every kind of item, a status bar for each kind of message, a button that opens a dialog, dividers, an image, and the variants the theme defines, each with a sample of its family.
The editor draws the gallery in the theme being edited (see Term::Fabulous::ThemeEditor::UI); the widgets read their looks themselves. A toast or a dialog opened from the gallery draws in that theme too.
PageUp, PageDown, Ctrl+Home and Ctrl+End scroll the gallery when the focused widget in it does not use them, and a widget that gets the focus is scrolled into view.
