对话框调整大小时，移动MFC按钮 [英] Move MFC Button, While dialog resizing

问题描述

我有一个带有一些按钮的对话框应用程序.但是在重新设置对话框大小时，按钮不会自动重新放置.

提前感谢您能否帮助我解决此问题.

Hi,

I had a dialog application with some buttons. But while re-sizing the dialog, the buttons are not automatically repositioned.

Could you please help me to fix this problem, thanks in advance.

推荐答案

尝试对WM_SIZE对话框的消息做出反应，
然后显式移动您的控件:)

Try to react to the WM_SIZE dialog''s message,
then to move your controls explicitly :)

// CPoint CYourDialog::m_cLastClientBottomRight
// is initalized in CYourDialog::OnInitDialog()
// as right-bottom point of its client rectangle

// Assumed, the OK button must be adapted in both directions:
void CYourDialog::OnSize(UINT nType, int cx, int cy)
{
  CRect crClient;
  GetClientRect(crClient);

  if (m_cBtnOK.GetSafeHwnd()) {
    CRect crControl;
    m_cBtnOK.GetWindowRect(crControl);
    ScreenToClient(crControl);

    crControl.OffsetRect(crClient.BottomRoght() - m_cLastClientBottomRight);
    m_cBtnOK.MoveWindow(crControl);
    m_cBtnOK.Invalidate();
  }

  m_cLastClientBottomRight = crClient.BottomRight();
}
