Usage(用法)

Create a Window(创建一个窗口)

显示原文

lv_win_create(parent) creates a Window with an empty header.


lv_win_create(parent) 创建一个标头为空的窗口。

Title and buttons(标头和按钮)

显示原文

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_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.


可以使用 lv_win_add_title(win, "The title") 将任意数量的文本(但通常只有一个)添加到标头中。

可以使用 lv_win_add_button(win, icon, button_width) 将控制按钮添加到窗口的标头 。 icon 可以是任何图像源, button_width 是按钮的宽度。

标头和按钮将按照调用函数的顺序添加。因此,添加一个按钮、一个文本和另外两个按钮将在左侧产生一个按钮,在右侧产生一个标头和两个按钮。标头的宽度设置为占据标头上的所有剩余空间。换句话说: 它将标头后添加的所有按钮推到右侧。

Get the parts(获取部分)

显示原文

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.


lv_win_get_header(win) 返回一个指向标头的指针, lv_win_get_content(win) 返回一个指向可以在窗口添加内容的容器指针。
