Layout tip – Opening a Popover with a ScriptPosted: March 11, 2015
I really like popovers – they’re the most useful interface feature to have been introduced to Filemaker for ages, and being able to add an OnObjectEnter script trigger adds to their usefulness, enabling us to do some stuff each time the popover opens.
But OnObjectEnter is a “Post” trigger (i.e. it runs after the event has happened), and sometimes it’s nicer to do the processing before the popover opens. Initialising fields is a good example, because we don’t want the existing (“old”) field contents displayed, however briefly, before the fields are cleared.
One way around this is to have:
- An ordinary (non-popover) button, which is the button visible to the user, and which the user clicks.
- A popover button, hidden from the user. (To make it hidden, I use the method suggested by ‘bfroo’ in the comments – ‘hide object when 1’ – so that it’s always hidden in Browse mode, but visible in Layout mode.)
- An object name for the popover itself.
I tend to put the popover button next to the other button, but different in colour to make it obvious that it’s not a part of the user’s view of the interface, like this:
(i.e. the ‘Analyse’ and ‘Outcomes’ buttons are the clickable buttons, and the little yellow ones next to them are the popover buttons.)
When the user clicks on the (non-popover) button, a script is performed. This script:
- Performs any pre-processing required,
- Goes to the object name of the popover, which has the effect of opening the popover.
- Refreshes the window.
The disadvantage is that it’s obviously a bit more work to set it up in the first place, but the added flexibility that this technique provides, makes it well worthwhile.
