Re: Subclassed edit control paint problem

Hi,
In the same situation I'm creating the Edit control with the proper size from the beginning. So there's no need to subclass the 2 messages you mentionned.

I get the dimensions as follows:

GetSubItemRect(iItem, iSubItem, LVIR_BOUNDS, pRect);
pRect.right--;
pRect.bottom--;

My Edit Create is borrowed from Bjarne Viksoe's Property Grid control:

http://www.viksoe.dk/code/propertygrid.htm

Have a look at CreateInplaceControl in PropertyItemImpl.h, this is what you call once you have the cell's rectangle.

Here's my code for the cell editing:

void FEditCell()
{
  CGridCell* pCell = GetColumnTrait(m_nSelectedCol);
  if ((!pCell) || (pCell->GetKind()<CELLKIND_EDIT) ||
      (!m_data->IsEditable(m_nSelectedRow,m_nSelectedCol)))
    return;

  // Send Notification to parent of ListView ctrl
  LV_DISPINFO dispinfo = {0};
  dispinfo.hdr.hwndFrom = m_hWnd;
  dispinfo.hdr.idFrom = GetDlgCtrlID();
  dispinfo.hdr.code = LVN_BEGINLABELEDIT;
  dispinfo.item.mask = LVIF_PARAM;
  dispinfo.item.iItem = m_nSelectedRow;
  dispinfo.item.iSubItem = m_nSelectedCol;
  dispinfo.item.lParam = 0;

  if (::SendMessage(GetParent(), WM_NOTIFY, GetDlgCtrlID(), (LPARAM)&dispinfo)==TRUE)
    return;	 // Parent didn't want to start edit

  // Create a new editor window
  RECT rcValue;
  FGetSubItemRect(m_nSelectedRow, m_nSelectedCol, &rcValue);
  rcValue.right--;   // Let the borders
  rcValue.bottom--;  // display (right/bottom)
  char szText[MAX_PATH];
  ZeroMemory(szText, MAX_PATH);
  GetItemText(m_nSelectedRow, m_nSelectedCol, szText, MAX_PATH);
  HWND hwndInplace = m_arrColumnTrait[m_nSelectedCol]->CreateInplaceControl(m_hWnd, rcValue, m_nSelectedRow, m_nSelectedCol, szText);

  if (hwndInplace) {
    // Activate the new editor window
    ATLASSERT(::IsWindow(m_hwndInplace));
    ::SetWindowPos(hwndInplace, HWND_TOP, 0,0,0,0, SWP_SHOWWINDOW|SWP_NOMOVE|SWP_NOSIZE);
    ::SetFocus(hwndInplace);

    m_arrColumnTrait[m_nSelectedCol]->Activate(PACT_SPACE, 0);
  }
}

Working fine so far.
