控件大小随窗口变化( 可多个控件,增加了tab下窗口大小,CCombox不能下拉 )

//功能,调整控件大小位置

//来源:网上

//类型:笔记

//个人修改过

如果是里面只有一两个控件倒好办，但控件太多的话这样做是不是重复劳动太多了？

有没有更好的办法啊？

视类中加成员函数和成员变量：
void SetControlInfo(WORD CtrlId);
protected:
int m_old_cx,m_old_cy;
CDWordArray m_control_info;

构造函数中初始化：
m_old_cx = m_old_cy = 0;

加控件信息的函数定义：
void CTestFormView::SetControlInfo(WORD CtrlId)
{
m_control_info.Add(CtrlId);

}


修改OnSize函数：
void CTestFormView::OnSize(UINT nType, int cx, int cy)
{
if(cx==0 || cy==0)
{
cx=800;
cy=600;
}
CFormView::OnSize(nType, cx, cy);
float dx_percent = (m_old_cx ==0)? 1 : (float)((float)cx/(float)m_old_cx);
float dy_percent = (m_old_cy ==0)? 1 : (float)((float)cy/(float)m_old_cy);

if(m_old_cx)
{
CRect WndRect;
CWnd *pWnd;
for(int i = 0; i < m_control_info.GetSize(); i++)
{
   pWnd = GetDlgItem(m_control_info[i]);
   if(!pWnd)
   {
   TRACE( "Control ID - %d NOT FOUND!!\n ",m_control_info[i]);

   continue;
   }

   pWnd-> GetWindowRect(&WndRect);
   ScreenToClient(&WndRect);

   WndRect.left = (int)(WndRect.left*dx_percent);
   WndRect.right = (int)(WndRect.right* dx_percent);
   WndRect.bottom = (int)(WndRect.bottom*dy_percent);
   WndRect.top = (int)(WndRect.top*dy_percent);

   pWnd-> MoveWindow(&WndRect);
}

}
m_old_cx = cx;
m_old_cy = cy;
}

在OnInitialUpdate函数( 窗口的是OnInitDialog函数 )中加入控件ID：
SetControlInfo(IDC_BUTTON1);
  。。。。。。。。。。。。。。。。

  运行，搞定！
Dialog也一样!

//刚刚用了一下,问题又来了,如果是窗口在tab控件下面的怎么办,网上找了一下,没有找到,只到自己想咯,

//第二个想法就用上了

//修改下上面的函数

void CTestFormView::OnSize(UINT nType, int cx, int cy)
{

CRect WndRect;
CWnd *pWnd;

if(cx==0 || cy==0)
{
cx=800;
cy=600;
}
CFormView::OnSize(nType, cx, cy);
float dx_percent = (m_old_cx ==0)? 1 : (float)((float)cx/(float)m_old_cx);
float dy_percent = (m_old_cy ==0)? 1 : (float)((float)cy/(float)m_old_cy);

if(m_old_cx)
{

for(int i = 0; i < m_control_info.GetSize(); i++)
{
   pWnd = GetDlgItem(m_control_info[i]);
   if(!pWnd)
   {
   TRACE( "Control ID - %d NOT FOUND!!\n ",m_control_info[i]);

   continue;
   }

   pWnd-> GetWindowRect(&WndRect);
   ScreenToClient(&WndRect);

   WndRect.left = (int)(WndRect.left*dx_percent);
   WndRect.right = (int)(WndRect.right* dx_percent);
   WndRect.bottom = (int)(WndRect.bottom*dy_percent);
   WndRect.top = (int)(WndRect.top*dy_percent);

   pWnd-> MoveWindow(&WndRect);
}

}
m_old_cx = cx;
m_old_cy = cy;

//tab子窗口大小

pWnd = GetDlgItem( IDC_SPORTLOGS_TAB0 );

if ( NULL != pWnd )

{

pWnd-> GetClientRect(&WndRect);

m_tab_EveryDay.MoveWindow(&WndRect);; //每天活动

m_tab_ActivityReport.MoveWindow(&WndRect);; //活动报告

m_tab_CateGory.MoveWindow(&WndRect);; //类别

m_tab_equipment.MoveWindow(&WndRect);; //设备

m_tab_athletes.MoveWindow(&WndRect);;//运动员

m_tab_path.MoveWindow(&WndRect);; //路径

m_tab_internet.MoveWindow(&WndRect);;//上网

m_tab_set.MoveWindow(&WndRect);;//设置

}

//红色的为修改过的

//问题又来了,发现如果窗口大小改变过,那下拉框控件( CCombox )竟然下拉不了,查查MFC库详解,竟然没有调整这个的

//后来想想,由MoveWindow搞的,就由它来解决,修改上面代码后完成 ,如下:(红色部分为新修改)
