filemaker pro 18 scrolling portal display

I have named the portal and a field in the portal but just get ? as the result.

I think there is a problem with the syntax. I'm not sure how this could be fixed, and perhaps it is a bug with Go, do you know of any ideas? However the same solution in Pro shows the correct first visible row. In GO 12, the max visible row it returns is 2, even if you are scrolled well down the portal. In testing this function I notice that it works great in FileMaker Pro 12, but is not working in FileMaker Go 12.

The first index you can see in your portal should be the same value the function returns.Īwesome! Thank you so much for taking the time to write this function for FM12 Arnold, I really appreciate it! This will print the actual index of each portal row. (B) To verify the correct return value, add a label with the text to the portal. The return value 5 means, the portal is scrolled so far down, that the first four portal rows are not or less than 50% of the row height visible. (A) If the function returns 1, the very first portal row is visible. (7) Scroll to a different row in the portal and call the function again. (6) Call the function (via data viewer or script or button): PortalFirstVisibleRow( 'myPortal' ) (3) Place an object into the portal, preferably a field from the portal table. The parameter _portal is the object name of the portal.īesides the object name for the portal, at least one object in the portal has to have an object name, too. Ĭalculates the index of the first visible row in a portal. THIS CF IS FOR FM12 ONLY! For a FM11 version of this function check out. _top2 = GetLayoutObjectAttribute( _object 'top' '' _row + 1 ) _top1 = GetLayoutObjectAttribute( _object 'top' '' _row ) _portalTop = GetLayoutObjectAttribute( _portal 'top' ) _objects = Substitute( '¨' & _objects & '¨' )

_objects = GetLayoutObjectAttribute( _portal 'containedObjects' ) $PortalFirstVisibleRow_object = If( _top = '' $PortalFirstVisibleRow_object ) $PortalFirstVisibleRow = If( _top = '' $PortalFirstVisibleRow + 1 ) _top = GetLayoutObjectAttribute( $PortalFirstVisibleRow_object 'top' '' $PortalFirstVisibleRow ) Return index of first visible row in a portal.įunction requires at least one named object in the portal.
