7 LVGL (Light and Versatile Graphics Library) is a free and open-source graphics
8 library providing everything you need to create an embedded GUI with easy-to-use
30 :ref:`basics_screen_widgets` on them, add :ref:`basics_widgets` onto those Screens.
33 drives LVGL's timers which, in turn, perform all of LVGL's time-related tasks:
35 - periodically refreshes displays,
36 - reads input devices,
37 - fires events,
38 - runs any animations, and
39 - runs user-created timers.

67 - A **Display** or **Display Panel** is the physical hardware displaying the pixels.
68 - A :ref:`display` object is an object in RAM that represents a **Display** meant
70 - A **Screen** is the "root" Widget in the Widget Trees mentioned above, and are

121 are automatically added as children to their parent Widgets at time of creation ---
131 - when the parent Widget moves, its children move with it;
132 - when the parent Widget is deleted, its children are deleted with it;
133 - a child Widget is only visible within its parent's boundaries; any part of a child
144 RAM (e.g. for quick re-display again later). Doing so:
146 - requires more RAM, but
147 - can save the time of repeatedly creating the Screen and its child Widgets;
148 - can be handy when a Screen is complex and/or can be made the :ref:`active_screen` frequently.

285 - :cpp:enumerator:`LV_STATE_DEFAULT`: Normal, released state
286 - :cpp:enumerator:`LV_STATE_CHECKED`: Toggled or checked state
287 - :cpp:enumerator:`LV_STATE_FOCUSED`: Focused via keypad or encoder or clicked via touchpad/mouse
288 - :cpp:enumerator:`LV_STATE_FOCUS_KEY`: Focused via keypad or encoder but not via touchpad/mouse
289 - :cpp:enumerator:`LV_STATE_EDITED`: Edit by an encoder
290 - :cpp:enumerator:`LV_STATE_HOVERED`: Hovered by mouse
291 - :cpp:enumerator:`LV_STATE_PRESSED`: Being pressed
292 - :cpp:enumerator:`LV_STATE_SCROLLED`: Being scrolled
293 - :cpp:enumerator:`LV_STATE_DISABLED`: Disabled
