I have an expanding subfile that I am attempting to see if there is a way to trigger a "Page Down" response using Sliding Scrollbar when the scroll gets to the bottom of the scrollbar (without using "Paging Controls").
Any help in this topic would be appreciated. Thanks in advance.
Hitting the "page down" key on your keyboard should do it.
But, the sliding scrollbar is not meant for this. It is meant for a situation where you show everything on the screen at once, and the scrollbar is used to scroll among what is on the screen. Since you want to page beyond what you have on the screen, the sliding scrollbar is not the right tool.
Do you know if Profound will add the PageDown response function when a "Sliding Scrollbar" reaches the bottom on a expanding subfile? This would be a nice feature for those that does not want or have to press a key "PageDown" on the keyboard (just point and click with the mouse).
Just a note that may enlighten why we are thinking in this manner. Using both "Sliding Scrollbar" and "Paging Controls" together could bring some confusion for some users that may think the subfile is at the end when the scrollbar reaches the bottom of the subfile. In addition, it is also nice to have the "Sliding Scrollbar" that allows users to use the wheel on the mouse which is a great feature and a productivity oriented function.
I personally think that would be unintuitive because the scrollbar would show you being at the bottom of the grid, and then clicking the down arrow from that shouldn't do anything -- it doesn't in other applications if the scrollbar shows you at the bottom, nothing happens when you scroll down.
In my opinion, this is not a proper use of the sliding scrollbar. Using the paging bar (or "paging controls", I think its called?) would make your application more intuitive.
But, if you really think Profound should consider changing this, you can file a feature request by contacting support@profoundlogic.com
