Parts and Styles

****************
|
|
|
|
The Window is built from other widgets so you can check their
|
|
documentation for details:
|
|
|
|
- Background: :ref:`lv_obj`
|
|
- Header on the background: :ref:`lv_obj`
|
|
- Title on the header: :ref:`lv_label`
|
|
- Buttons on the header: :ref:`lv_button`
|
|
- Content area on the background: :ref:`lv_obj`

|
Usage
|
|
*****
|
|
|
|
Create a Window
|
|
---------------
|
|
|
|
:cpp:expr:`lv_win_create(parent, header_height)` creates a Window with an empty
|
|
header.
|
|
|
|
Title and buttons
|
|
-----------------
|
|
|
|
Any number of texts (but typically only one) can be added to the header
|
|
with :cpp:expr:`lv_win_add_title(win, "The title")`.
|
|
|
|
Control buttons can be added to the window's header with
|
|
:cpp:expr:`lv_win_add_button(win, icon, button_width)`. ``icon`` can be any image
|
|
source, and ``button_width`` is the width of the button.
|
|
|
|
The title and the buttons will be added in the order the functions are
|
|
called. So adding a button, a text and two other buttons will result in
|
|
a button on the left, a title, and 2 buttons on the right. The width of
|
|
the title is set to take all the remaining space on the header. In other
|
|
words: it pushes to the right all the buttons that are added after the
|
|
title.
