mre下的控件实现(四、Button使用)
这里有一个实例使用(一、实现)中的按钮控件,达到的效果如下图所示,

用mre sdk(这里使用的是mre sdk 2.5版本)创建一个工程,工程名为mtid(实际上这个是我要在做一个工具)。
//生成的工程,自动生成mtid.c,代码改动成如下
//主窗体在这里创建

#include "vmio.h"
#include "vmgraph.h"
#include "vmchset.h"
#include "vmstdlib.h"

#include "vmlog.h"
#include "MtidView.h"
#include "widget.h"
