ADF 11gR2 DVT – Visual changes in Carousel and Hierarchy Viewer
Two small new features caught my eye while scanning the 11gR2 new features list for ADF DVT. One applies to the Carousel, the other to the Hierachy Viewer. They both have been extended with an additional appearance.
The carousel by default renders – as it always did – in a circular mode, with one pane (usually an image) with focus and several others positioned underneath it – like so:
11gR2 introduces a new property called DisplayItems that either has the value circular or the value oneByOne. With this latter value,
you will only see a single pane (image) – the one that has focus. Only when you scroll to the next or previous pane or slide will you briefly see a slide transition, which with a lot of patience I was able to capture in the next screenshot:
Note: outside of slide transactions, the carousel will just show the focus pane:
The hierarchy viewer already has a serious number of display orientations, from vertical and horizontal to radial and tree.
A typical layout for the hierarchy viewer would be something like this:
A new layout value is introduced, called circle.
This same hierarchy displayed with the circle layout would render like this:
With node 7698 further expanded, the hierarchy is presented with an additional level of child nodes:
It is not earth shattering – but certainly nice and potentially useful.
