Re: wxGrid, is there any way to get the DC?

Works perfectly, here is some code in case it's useful for someone else.


void MyTableWindow::OnLabelDoubleClick(wxGridEvent& e)
{
wxWindow *pGridWindow = m_pGrid->GetGridWindow();

if (pGridWindow != NULL)
{
int nCol = e.GetCol();
int nRow = e.GetRow();

  wxString strText = m_pGrid->GetColLabelValue(nCol);  //Or strText = 
m_pGrid->GetRowLabelValue(nRow);

wxClientDC dc(pGridWindow);

dc.SetFont(m_pGrid->GetCellFont(nRow, nCol));
wxArrayInt widths;
bool bResult = dc.GetPartialTextExtents(strText, widths);
  }
}
