Oracle Forms - Loosing focus when a Timer expires
Posted on 2010-11-15
We are implementing a Timer in our Oracle Forms application to implement an Emergency Broadcast solution. The Timer is set on our 'welcome' form, when the timer expires the form checks whether an emergency message has been added to the database and displays it.
This works, however we have noticed some undesirable effects on other screens when the timer expires - focus is momentarily switches back to the 'welcome' screen and interrupts user activity. In some cases the cursor goes back to column 1 of a field, other times a canvas is incorrectly displayed and also an opened menu is removed from display.
We can work-around most of these side-effects, although a solution to the removal of an open menu is eluding us. But we are worried about other un-noticed side-effects.
Is there any way we can configure the timer without it switching focus back to its form when it expires? Or is there another way we can regularly check whether data has been added to the database?
