Window (lv_win)
Overview
The Window is container-like object built from a header with title and buttons and a content area.
Parts and Styles
The Window is built from other widgets so you can check their documentation for details:
- Background: lv_obj
- Header on the background: lv_obj
- Title on the header: lv_label
- Buttons on the header: lv_btn
- Content area on the background: lv_obj
Usage
Create a Window
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 lv_win_add_title(win, "The title")
.
Control buttons can be added to the window's header with lv_win_add_btn(win, icon, btn_width)
. icon
can be any image source, and btn_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.
Get the parts
lv_win_get_header(win)
returns a pointer to the header, lv_win_get_content(win)
returns a pointer to the content container to which the content of the window can be added.
