c++运行程序 鼠标点击按钮 (c++)(windows)

简介

这是在黑漆漆的程序中,制造用户可点击的按钮,来决定程序下一步该作什么,的基本代码。

详解

头文件

<cstdio><windows.h>

结构体

//这不全别复制
struct Button
{
	int x,y,lenx,leny,color1,color0;
	char * s;
	bool nowpoint;
};

xy是按钮左上角相对于当前窗口的位置(左右是x,上下是y
lenxleny按钮的长与宽(左右是x,上下是y
color1color0是鼠标否或是在按钮上时按钮的颜色
颜色详见 这个
s是输出的一个串
例如lenx=3,leny=3的按钮,是

[ egin{matrix} a b c \ d e f \ g h i \ end{matrix} ]

s"abcdefghi"
nowpoint不用管,用户用不到。

功能

代码 功能
Button a 新建一个按钮,默认为"none"
a.Print(···) 输出a
a.SetButton(···) 初始化并输出,返回时为串的长度是(1)否(0)符合规定
a.Check(···) 判断鼠标是(1)否(0)点击的a按钮
a.Delete(···) 删去a按钮,加引号的删除

细节

在Check的GetAsyncKeyState中
可选VK_RBUTTON(鼠标右键)或VK_LBUTTON(鼠标左键)
由于win10按左键会触发选择而不是按左键,所以win10推荐用右键
Nowcolor是当前控制台的颜色(详见这个
