滑块与按钮控件示例(12_UiStatusBar)

滑块与按钮控件

此示例展示以下控件的使用方法:

• UiStatusBar

• UiButton

• UiScrollWin

滑块控件UiStatusBar 使用流程

• ID定义，对象定义不再详述

  UiStatusBar m_StatusBar;
  

• 在重载函数OnInitDialog()中进行控件设置

  m_StatusBar.SetPos(GetWidth()-350,25,260,20);
  m_StatusBar.SetID(MZ_IDC_STATUSBAR);
  //进度条控件的最大与最小范围
  m_StatusBar.SetRange(0,100);
  //设置进度条的当前位置
  m_StatusBar.SetPadpos(50);
  

• 进度条控件的操作

  //返回进度条的当前位置
  m_StatusBar.GetPadpos();
  //设置进度条的当前位置
  m_StatusBar.SetPadpos(0);
  

示例代码展示:

• 如何使用CUiStatusBar,并显示CUiStatusBar的当前位置

• 如何使用UiButton，M8SDK提供了switch button,select button,line button,arrow button等多种按钮方式

滑块滑动时,更新滑块的位置：

  WCHAR wstr[10];
  wsprintf(wstr,L"%d%%",m_StatusBar.GetPadpos());
  m_StcValue.SetText(wstr);
  m_StcValue.Invalidate();
  m_StcValue.Update();

//请按照以步骤运行此实例代码：
//首先, 打开VS2005/2008创建一个Win 32智能设备项目
//在项目向导中选择M8SDK, 并勾选空项目
//然后,在项目中新建一个cpp文件,将此处代码拷贝到cpp文件中
//最后,按照M8SDK的帮助文档,配置项目属性
//现在,可以运行此程序了
#include <mzfc_inc.h>

//此代码演示了：
//创建和初始化应用程序
//创建和初始化窗体
//使用UiButton控件，M8SDK提供了
//switch button,select button,line button,arrow button等多种按钮
//使用滑块控件(CUiStatusBar)
//使用UiScrollWin放置按钮
