+# Window (lv_win)
+
+## Overview
+
+The Window is container-like objects built from a header with title and button and a content area. 
+
+ 
+## Parts and Styles
+The main part is `LV_WIN_PART_BG` which holds the two other real parts:
+1. `LV_WIN_PART_HEADER`: a header [Container](/widgets/cont) on the top with a title and control buttons
+2. `LV_WIN_PART_CONTENT_SCRL` the scrollable part of a [Page](/widgets/page) for the content below the header. 
+
+
+Besides these, `LV_WIN_PART_CONTENT_SCRL` has a scrollbar part called `LV_WIN_PART_CONTENT_SCRL`.
+Read the documentation of [Page](/widgets/page) for more details on the scrollbars.
+
+All parts supports the typical background properties. The title uses the *Text* properties of the header part.
+ 
+The height of the control buttons is: *header height - header padding_top -  header padding_bottom*.
+ 
+
+### Title
+On the header, there is a title which can be modified by: `lv_win_set_title(win, "New title")`. 
+
+### Control buttons
+Control buttons can be added to the right of the window header with: `lv_win_add_btn_right(win, LV_SYMBOL_CLOSE)`, to add a button to the left side of the window header use `lv_win_add_btn_left(win, LV_SYMBOL_CLOSE)` instead.
+The second parameter is an [Image](/widgets/img) source so it can be a symbol, a pointer to an `lv_img_dsc_t `variable or a path to file.
+
+The width of the buttons can be set with `lv_win_set_btn_width(win, w)`. If `w == 0` the buttons will be square-shaped.
+
+`lv_win_close_event_cb` can be used as an event callback to close the Window.
+
+### Scrollbars
+
+The scrollbar behavior can be set by `lv_win_set_scrlbar_mode(win, LV_SCRLBAR_MODE_...)`. 
+See [Page](/widgets/page) for details.
+
+### Manual scroll and focus
+To scroll the Window directly you can use `lv_win_scroll_hor(win, dist_px)` or `lv_win_scroll_ver(win, dist_px)`.
+
+To make the Window show an object on it use `lv_win_focus(win, child, LV_ANIM_ON/OFF)`.
+
+The time of scroll and focus animations can  be adjusted with `lv_win_set_anim_time(win, anim_time_ms)`
+
+### Layout
+To set a layout for the content use `lv_win_set_layout(win, LV_LAYOUT_...)`. 
+See [Container](/widgets/cont) for details.
+
