xBrowse - Headers are not painted

[StefanHaupt]

Hi all,

in an empty xBrowse-object (that means, the data did not meet the scope condition and no data lines are shown) the header is not painted or it´s hidden.

Only if i leftclick on the header, i can see it.

What can i do to get all headers always visible ?

kind regards
Stefan

Nobody who noticed this behavior ?

Yes, I noticed it in little samples but it doesn't seem to be easely reproduceable.

Enrico,

I can reproduce it all the time, every time the datalines are empty. I have searched in the class, but i did not find anything what stops the painting of the header.

I will try to build a little sample

Stefan,

In Class TXBrowse Method Paint() comment out this line and please try it again:

Code: Select all  Expand view  RUN

   if ::nLen == 0
      // ::EraseData( nFirstRow  )
      return nil
   endif

Antonio, please note that I saw the problem in some situations also when records were present.

Enrico,

That may be another problem. In this case is when there are no records to show

[Enrico Maria Giordano]

Ok.

Antonio,

if i only comment out ::EraseData (...), it´s not working, but if i comment out return nil, than it´s working as exspected, all headers are shown.

Code: Select all  Expand view  RUN

if ::nLen == 0
      // ::EraseData( nFirstRow  )
      // return nil
   endif

But i don´t know, if this has side effects in other situations.

many thanks

kind regards
Stefan

Stefan,

It looks ok. Lets change it this way:

Code: Select all  Expand view  RUN

   /* To paint headers when there are no records to show
   if ::nLen == 0
      ::EraseData( nFirstRow  )
      return nil
   endif
   */


[Gianni]

I think it should be like this:

Code: Select all  Expand view  RUN

   if ::nLen == 0
      ::EraseData( nFirstRow  )
      ::DispEnd( aInfo )   // gs
      return nil
   endif


In this way it don't paint an empty row.

Let me know if it works

Regards
Gianni
