Progress Stopped


Progress Stopped ( id ) -> Function result

Parameter	Type	Description
id	Longint	ID of progress bar
Function result	Boolean	True = User clicked the Stop button

Description

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)
