1.首先在初始化函数中,FormView在OnInitialUpdate(),Dialog在OnInitDialog()中初始化控件的大小。
//开始初始化控件大小
m_IsInitialed = false;
CRect m_ClientRect;
this->GetClientRect(&m_ClientRect);
CSize m_Forsize;
m_Forsize = GetTotalSize();//在资源编辑器中定好大小后,程序运行时大小(不管最大化和最小化,该大小均为同一个值),客户区大于或等于显示的大小
double m_x = (double)m_ClientRect.Width() / m_Forsize.cx;//宽度方向发大倍数
double m_y = (double)m_ClientRect.Height() / m_Forsize.cy;//高度方向发大倍数
//调整控件的大小
CWnd *pWnd = NULL;
pWnd = GetWindow(GW_CHILD);
while(pWnd)//判断是否为空,因为对话框创建时会调用此函数,而当时控件还未创建
{
CRect rect; //获取控件变化前大小
pWnd->GetWindowRect(&rect);
ScreenToClient(&rect);//将控件大小转换为在对话框中的区域坐标
m_ControlRect.insert(pair(pWnd->GetDlgCtrlID(), rect));//保存控件的初始大小,以便在OnSize函数中继续使用
int width = rect.Width();
int height = rect.Height();
WCHAR szBuf[256];
GetClassName(pWnd->m_hWnd,szBuf,256);
if( _tcsicmp(szBuf,_T("Edit")) == 0)
{
//Edit只是位置变化,大小没有变
rect.top = m_y * rect.top;
rect.left = m_x * rect.left;
rect.bottom = rect.top + height;
rect.right = rect.left + width;
}
else
{
//其它控件位置和大小均变化
rect.top = m_y * rect.top;
rect.left = m_x * rect.left;
rect.bottom = m_y * rect.bottom;
rect.right = m_x * rect.right;
}
pWnd->MoveWindow(&rect);//设置控件大小
pWnd = pWnd->GetWindow(GW_HWNDNEXT);
}
//控件初始化结束
m_IsInitialed = true;
2.如果界面在运行时大小可以改变,则在OnSize函数中加入如下代码
// TODO: 在此处添加消息处理程序代码
CFormView::ShowScrollBar(SB_BOTH, false);//设置没有滚动条,视情况而定。
//在界面不是最小化并且已经初始化完毕
if (!IsIconic() && m_IsInitialed)
{
CSize m_Forsize;
m_Forsize = GetTotalSize();
double m_x = (double)cx / m_Forsize.cx;
double m_y = (double)cy / m_Forsize.cy;
//读取控件的初始大小
map::iterator pos = m_ControlRect.begin();
for (; pos != m_ControlRect.end(); ++pos)
{
CRect rect = pos->second;
int width = rect.Width();
int height = rect.Height();
WCHAR szBuf[256];
GetClassName(GetDlgItem(pos->first)->m_hWnd,szBuf,256);
if( _tcsicmp(szBuf,_T("Edit")) == 0)
{
rect.top = m_y * rect.top;
rect.left = m_x * rect.left;
rect.bottom = rect.top + height;
rect.right = rect.left + width;
}
else
{
rect.top = m_y * rect.top;
rect.left = m_x * rect.left;
rect.bottom = m_y * rect.bottom;
rect.right = m_x * rect.right;
}
GetDlgItem(pos->first)->MoveWindow(rect);
}
}
