Progress Stopped 


 

Progress Stopped ( id ) -> Function result 
Parameter Type   Description
id  Longint in ID of progress bar
Function result  Boolean in True = User clicked the Stop button

The Progress Stopped method returns True when a user clicks on the Stop button of the progress bar designated by the id parameter.

You must call this method to test whether the user clicked the Stop button. The button does not trigger an event itself.

Example  

Example of progress bar on a loop:

 $ProgressID:=Progress New // create a new progress bar
  // The progress bar must have a Stop button
 Progress SET BUTTON ENABLED($ProgressID;True)
 For($i;1;100)
  // As long as progress is not stopped...
    If(Not(Progress Stopped($ProgressID)))
       Progress SET TITLE($ProgressID;"Test progress #"+String($ProgressID))
       Progress SET PROGRESS($ProgressID;$i/100)
       Progress SET MESSAGE($ProgressID;String(100*$i/100)+" %")
       (...)
    Else // The user clicks on Stop
       $i:=100 // We exit the loop
    End if
 End for
  // Final closing of progress bar (the Stop button itself does nothing)
 Progress QUIT($ProgressID)
