TIMER(period)
| TIMER | Specifies a periodic event. |
| period | An integer constant or constant expression specifying the interval between timed events, in hundredths of a second. If zero (0), no timed events generate. |
The TIMER attribute (PROP:TIMER) specifies generation of a periodic field-independent event (EVENT:Timer) whenever the time period passes. The FOCUS() procedure returns the number of the control that currently has focus at the time of the event.
Value of timer has the UINT type. The Clarion IDE limits the timer value to 65365. If a higher value is required, it must be set using the property assignment statement.
Example:
RunClock PROCEDURE
ShowTime LONG
TimerValue UNSIGNED
!A WINDOW with a timed event occurring every second:
Win1 WINDOW,TIMER(100)
STRING(@T4),USE(ShowTime)
END
CODE
OPEN(Win1)
!You can also set the TIMER at runtime like this:
!TimerValue = 100000 !1000 second delay
!Win1{PROP:TIMER} = TimerValue
ShowTime = CLOCK()
ACCEPT
CASE EVENT()
OF EVENT:Timer
ShowTime = CLOCK()
DISPLAY
END
END
CLOSE(Win1)
