Hi Andreas,
I m not using any timer for this just simple i wrote the below code on when-button-pressed trigger
DECLARE
BAR NUMBER := 0;
BAR_STEP NUMBER;
VW_ID VIEWPORT;
BEGIN
SET_ITEM_PROPERTY('EMPLOYEE.BAR',VISIBLE,PROPERTY_TRUE);
BAR_STEP := 5000;
FOR I IN 1 .. 1350000 LOOP
IF(MOD(I,BAR_STEP) = 0)THEN
BAR := BAR - 2;
SET_ITEM_PROPERTY('EMPLOYEE.BAR',WIDTH,BAR);
SYNCHRONIZE;
END IF;
END LOOP;
SET_ITEM_PROPERTY('EMPLOYEE.BAR',VISIBLE,PROPERTY_FALSE);
VW_ID :=FIND_VIEW('CONTROL');
SET_VIEW_PROPERTY(VW_ID,VIEWPORT_X_POS,22);
SET_VIEW_PROPERTY(VW_ID,VIEWPORT_Y_POS,361);
SET_VIEW_PROPERTY(VW_ID,VISIBLE,PROPERTY_TRUE);
END;
and in When-new-form instance.
SET_ITEM_PROPERTY('EMPLOYEE.BAR',WIDTH,0);
SET_ITEM_PROPERTY('EMPLOYEE.BAR',VISIBLE,PROPERTY_FALSE);
and this is my testing purpose i didnt use this on realtime.
