Progress Bar on Dialog

[Bill Simmeth]

Does anyone have an example of how to create a progress bar on a dialog? I have tried to define the dialog from a resource and also to create it from scratch. But, I have not been able to get either to function properly.

Thanks in advance...

Thank you. I have a sample running now. On a dialog, progress bar seems to behave a bit strange. Even though it reports a range of 0 to 10, it acts as though the range is 0,100.

Bill,

Would you mind to post your sample here so we can review it ?

Also you may review samples\TestProg.prg

Hi Antonio,

I have included code below. I used the samples\testprog.prg as a guide but needed to place the progress bar on a dialog, not the window. I was unable to do this using a dialog from a resource. So, I built the dialog dynamically.

I added a function to post the nMin, nMax and nPos of the bar so you see what happens.

Also, it looks like the default DLG_CHARPIX_H and DLG_CHARPIX_W need to be adjusted for FWPPC as they yield objects too large.

Thanks!

Bill,

Use Method SetRange() from ON INIT and check the bounds:

   @ 3, 1 BUTTON "-" OF oDlg SIZE 20, 20  ; 
      ACTION ( if( oPgr:nPosition > 0, oPgr:nPosition -= 10, ), BarStat( oSay, oPgr ) ) 

   @ 3, 4 BUTTON "+" OF oDlg SIZE 20, 20  ; 
      ACTION ( if( oPgr:nPosition < 100, oPgr:nPosition += 10, ), BarStat( oSay, oPgr ) ) 

   ACTIVATE DIALOG oDlg ON INIT ( oPgr:SetRange( 0, 100 ), oPgr:nPosition := 50, BarStat( oSay, oPgr ) )
