MQL5 Standard Library Panels And Dialogs. Check Function

https://www.mql5.com/en/docs/standardlibrary/controls/ccheckgroup

Thank you, but you sent me the link to the page that I made the screenshot of (and I have taken the link in the file above) .

Unfortunately, this method is not available on the list above.

m_check_group.Check(0,1<<0);

I have only found "Checked" method there:

https://www.mql5.com/en/docs/standardlibrary/controls/ccheckbox.&nbsp;

Yes, you are correct. That method is indeed missing from the documentation. You will have to rely on the source code of the "MQL5\Include\Controls\CheckGroup.mqh" file to see what it does:

int CCheckGroup::Check(const int idx) const
  {
//--- check
   if(idx>=m_values.Total())
      return(0);
//---
   return(m_states[idx]);
  }

bool CCheckGroup::Check(const int idx,const int value)
  {
//--- check
   if(idx>=m_values.Total())
      return(false);
//---
   bool res=(m_states.Update(idx,value) && Redraw());
//--- change value
   if(res && idx<64)
     {
      if(m_rows[idx].Checked())
         Value(m_value|m_values.At(idx));
      else
         Value(m_value&(~m_values.At(idx)));
     }
//---
   return(res);
  }

Thanks !

Here, most of it is so well documented that I forgot to look at the mqh file  :D
