MQL5 Standard Library Panels And Dialogs. Check Function

[Michal Herda]

Hello !

As this is my first post this forum, I would like to extend a warm welcome to Everyone !

Can anyone explain or show, where in documentation is function Check ?

And what this function arguments mean, please.

I have found this in CCheckGroup code example.

It is marked on attached file.

Sorry, if I haven't notice, but it seems it is skipped in documentation.

Regards

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:

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);
  }

It's not in documentation, but you can find it's source in the file you've attached and understand what it does.

Thanks !

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