btnbmp activated when selecting a record

Silvio.Falconi · Post by **Silvio.Falconi** » Sat Mar 08, 2025 11:03 am

similarly to Cristobal's example barchange.prg that uses a buttonbar and some buttons, I would like to do the same thing but without the buttonbar i.e. I have 6 buttons under an xbrowse (the ones that start from the left)

and when I click on a record I would like to display only some of them, how could I do it?

perhaps I must use Newat of bar class But I not Know How make

I tried with

Code: Select all | Expand

@  oBrw:nBottom+5, 5 BUTTONBAR oBar SIZE 90,200 BUTTONSIZE 90,24  OF oDlg

and it make this error

Code: Select all | Expand

Error occurred at: 03/08/25, 12:22:05
   Error description: Error FiveWin/6  Cannot create window or control:

You are creating a button here with no Bar created already:

Code: Select all | Expand

case nbar = 1
         aBtnMenu := array(6)
         DEFINE BUTTON aBtnMenu[1] OF oBar PROMPT "Nuovo" RESOURCE "NEW_SMALLBRW"  LEFT;
                 ACTION  NIL

If you use DEFINE BUTTONBAR oBar OF oDlg SIZE 80,70 TOP NOBORDER 2015 run ok

if you use @ 100,10 BUTTONBAR oBar SIZE 450, 22 BUTTONSIZE 90, 24 OF oDlg NOT run

I tried also with
