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。
view plaincopy to clipboardprint?
01.//开始初始化控件大小
02. m_IsInitialed = false;
03.
04. CRect m_ClientRect;
05. this->GetClientRect(&m_ClientRect);
06. CSize m_Forsize;
07. 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
08. double m_x = (double)m_ClientRect.Width() / m_Forsize.cx;//宽度方向发大倍数
09. double m_y = (double)m_ClientRect.Height() / m_Forsize.cy;//高度方向发大倍数
10.
11. //调整控件的大小
12. CWnd *pWnd = NULL;
13. pWnd = GetWindow(GW_CHILD);
14. 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
15. {
16. CRect rect; //获取控件变化前大小
17. pWnd->GetWindowRect(&rect);
18. ScreenToClient(&rect);//将控件大小转换为在对话框中的区域坐标
19. m_ControlRect.insert(pair<int, CRect>(pWnd->GetDlgCtrlID(), rect));//保存控件的初始大小,以便在OnSize函数中继续使用
20. int width = rect.Width();
21. int height = rect.Height();
22.
23. WCHAR szBuf[256];
24. GetClassName(pWnd->m_hWnd,szBuf,256);
25. if( _tcsicmp(szBuf,_T("Edit")) == 0)
26. {
27. //Edit只是位置变化,大小没有变
28. rect.top = m_y * rect.top;
29. rect.left = m_x * rect.left;
30. rect.bottom = rect.top + height;
31. rect.right = rect.left + width;
32. }
33. else
34. {
35. //其它控件位置和大小均变化
36. rect.top = m_y * rect.top;
37. rect.left = m_x * rect.left;
38. rect.bottom = m_y * rect.bottom;
39. rect.right = m_x * rect.right;
40. }
41.
42. pWnd->MoveWindow(&rect);//设置控件大小
43. pWnd = pWnd->GetWindow(GW_HWNDNEXT);
44. }
45.
46. //控件初始化结束
47. m_IsInitialed = true;
//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<int, CRect>(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
view plaincopy to clipboardprint?
01.// TODO: 在此处添加消息处理程序代码
02. CFormView::ShowScrollBar(SB_BOTH, false);//设置没有滚动条,视情况而定。
03. //在界面不是最小化并且已经初始化完毕
04. if (!IsIconic() && m_IsInitialed)
05. {
06. CSize m_Forsize;
07. m_Forsize = GetTotalSize();
08. double m_x = (double)cx / m_Forsize.cx;
09. double m_y = (double)cy / m_Forsize.cy;
10.
11. //读取控件的初始大小
12. map<int, CRect>::iterator pos = m_ControlRect.begin();
13. for (; pos != m_ControlRect.end(); ++pos)
14. {
15. CRect rect = pos->second;
16. int width = rect.Width();
17. int height = rect.Height();
18.
19. WCHAR szBuf[256];
20. GetClassName(GetDlgItem(pos->first)->m_hWnd,szBuf,256);
21. if( _tcsicmp(szBuf,_T("Edit")) == 0)
22. {
23. rect.top = m_y * rect.top;
24. rect.left = m_x * rect.left;
25. rect.bottom = rect.top + height;
26. rect.right = rect.left + width;
27. }
28. else
29. {
30. rect.top = m_y * rect.top;
31. rect.left = m_x * rect.left;
32. rect.bottom = m_y * rect.bottom;
33. rect.right = m_x * rect.right;
34. }
35. GetDlgItem(pos->first)->MoveWindow(rect);
36. }
37. }
// 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<int, CRect>::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);
}
}
或在OnShowWindow()函数中加入也可以(特别是在对话框作为tabpage时)
