UI.condition_layout.layoutIconRows

调用方式

UI.condition_layout.layoutIconRows(content, children, width)

记录依赖项 UI.condition_layout.layoutIconRows，然后按该名称调用。带命名空间的调用不会传入 self：请使用冒号调用，或自行传入该对象。

作用

Lays out the "RM-IconRows" container: an icon on the left, vertically centered beside the rows of fields, and an optional side widget (marked with the side user data) that sits beside the last row when there is room and below the rows when there is not. Positions every child under content.

参数

名称	类型	作用
`content`	`table`	Frame the children are positioned in.
`children`	`table`	Child widgets: the icon first, then the field rows, and at most one side widget.
`width`	`number`	Available width in pixels.

返回值

1	`number`	The total height used, in pixels; 0 when there is no icon or no row.

版本

内置辅助函数在每个版本上都会注册。不同的是它们读取的游戏 API；某个 API 缺失时，辅助函数会改用后备方案，或返回 nil 并附上原因。

它不直接读取任何游戏 API。

插件如何调用它

UI.condition_layout.constructor

y=layoutIconRows(frame,self.children,width)

依赖项

ICON_ROWS_GAP (builtin:UI/condition_layout.lua:ICON_ROWS_GAP)
ICON_ROWS_MINIMUM (builtin:UI/condition_layout.lua:ICON_ROWS_MINIMUM)

源码

UI/condition_layout.lua，第 56 行。在游戏中为只读；“复制”会生成一份可编辑的副本。
