MFC中当改变对话框大小时怎么让控件自动调整大小？让控件随对话框的改变而调整大小
有代码的可以发给我，我邮箱是[e-mail]

[oyljerry]

响应WM_SIZE消息，然后MoveWindow等调整各个控件成比例

[ActiveFrank]

OnSize函数里面 MoveWindows

用法: (如 CTinyIeDlg )

1. 初始化

BOOL CTinyIeDlg::OnInitDialog()

{

CDialog::OnInitDialog();

…

m_AutoPos.InitOrgSize(this);

m_AutoPos.AddItem(IDC_COMBOBOXEX1, TRUE, 0, 0, 100, 0);

m_AutoPos.AddItem(IDOK, TRUE, 100, 0, 0, 0);

…

return TRUE; // 除非设置了控件的焦点，否则返回 TRUE

}



2. OnSize

void CTinyIeDlg::OnSize(UINT nType, int cx, int cy)

{

m_AutoPos.OnParentSize(cx, cy);



CDialog::OnSize(nType, cx, cy);

// TODO: Add your message handler code here

}
