There are some GUI state that you want the GUI library to retain, even in an immediate mode library such asegui. This includes position and sizes of windows and how far the user has scrolled in some UI. In these cases you need to provideeguiwith a seed of a unique identifier (unique...
if nargout [varargout{1:nargout}] = gui_mainfcn(gui_State, varargin{:}); else gui_mainfcn(gui_State, varargin{:}); end 解析 一下这个主函数:首先 gui_State是一个结构,指定了figure打开和输出函数, 开始 gui_CallBack为空,如果输入参数个数不为0,接下来将输入第一个参数传递给gui_State.callback。

1. 编写State 首先为程序编写一个State,这个核心概念在学习Vue和React或者Flutter的时候必然会用到,这里暂时不做解释,直接给出代码 struct Counter {value: i32,// The local state of the two buttonsincrement_button: button::State,decrement_button: button::State,} ...
