对话框学习3
学习一个收缩对话框的方法
在C***Dlg类中的OnInitDialog函数里
CRect winRect; GetWindowRect(winRect); m_winWidth = winRect.right; /*CString str; str.Format("%d", winRect.Width()); AfxMessageBox(str);*/ CRect btRect; GetDlgItem(IDC_BUTTON1)->GetWindowRect(btRect); m_shrinkWidth = btRect.right; winRect.SetRect(winRect.left, winRect.top, winRect.right, winRect.bottom);
GetWindowRect是获取整个对话框的CRect值
GetDlgItem(IDC_BUTTON1)->GetWindowRect(btRect)则是获取一个控件(按钮)的CRect值,并且在这里记录下来
双击button1响应消息并添加代码:
void CShrinkDlg::OnBnClickedButton1() { // TODO: 在此添加控件通知处理程序代码 CRect winRect; GetWindowRect(winRect); if(m_shrikn){ winRect.SetRect(winRect.left, winRect.top, winRect.left + m_winWidth, winRect.bottom); GetDlgItem(IDC_BUTTON1)->SetWindowText("<<"); }else{ winRect.SetRect(winRect.left, winRect.top, winRect.left + m_shrinkWidth, winRect.bottom); GetDlgItem(IDC_BUTTON1)->SetWindowTextA(">>"); } MoveWindow(winRect, TRUE); m_shrikn = ! m_shrikn; }
通过SetRect函数来重新设定对话框大小
并通过MoveWindows来实现对话框
写代码好累啊!
