Refreshing a Get

[Wolfgang Ciriack]

Hello,
i have a LISTBOX and a SAY object and i want to show some information of the selected item in the SAY object.

Code: Select all  Expand view

@ 0, 0 LISTBOX oBrw ;                       
      FIELDS hBmp, auftrag->zeit, auftrag->strasse ;
      HEADERS "", "Zeit", "Strasse" ;
      ON DBLCLICK ShowDetails(auftrag->(recno())) ;
      ON CHANGE (cTxt:=auftrag->straufart, oS1:SetText(cTxt)) ;
      SIZE 240, 180

@12,0 SAY oS1 VAR cTxt SIZE 240,20 OF oWnd FONT oSayFont BORDER


I tried oS1:Refresh() and oS1:SetText(cTxt) in the ON CHANGE statement of the LISTBOX, but i get always "No exported method". Is the GET object not of type TSay or is there simply something wrong with my coding ?

Wolfgang,

Your code is fine, except that it tries to send a message to the SAY object before it is created. Modify it this way:

Code: Select all  Expand view

@ 0, 0 LISTBOX oBrw ;                       
      FIELDS hBmp, auftrag->zeit, auftrag->strasse ;
      HEADERS "", "Zeit", "Strasse" ;
      ON DBLCLICK ShowDetails(auftrag->(recno())) ;
      ON CHANGE (cTxt:=auftrag->straufart, If( oS1 != nil, oS1:SetText(cTxt),)) ;
      SIZE 240, 180

Hi Antonio,
i have two more questions.

Is there a possibilty to have a bigger row height in the LISTBOX or two rows for each record ?

How can i have different bitmaps (hbmp) dependant on the content of one field ?

Yes, you have to use a larger font for it. Here I show you a working example.

Yes, in this same example I show you how to use as many bitmaps as needed.
