bind functionality

Support Question

Hello there, first of all, thank you for this wonderful library.
I've been using it instead of regular javafx for the fast few while and I really enjoy using it. However I have encountered a few roadblocks.
What would be the correct way to emulate the infamous "fit-to-parent" AnchorPane functionality? My so far unsuccessful approach was something like this:

(controls/anchor-pane
  :children 
    [(controls/some-control 
      :anchor-pane/top-anchor 0.0
      :anchor-pane/bottom-anchor 0.0
      :anchor-pane/left-anchor 0.0
      :anchor-pane/right-anchor 0.0)])

But for some controls (ImageView cough) I know, this just won't cut it in the long run. So are there major hurdles for the nested-properties branch to get merged? I looked at the source and am looking forward to the :bind/property syntax with [:id :prop] values. I don't really get the complete picture of what is depending on what right now, but with some pointers I would like to look into this and help if possible/necessary.

Wow I was totally on the wrong track about the AnchorPane. The above approach works as expected. I just messed up the camel->kabob in my head.

Everything was wrapped inside an HBox and if you want to call the parents

HBox.SetHgrow

method, the correct keyword-value-combo to use here is:

(controls/anchor-pane
  :h-box/hgrow javafx.scene.layout.Priority/ALWAYS
  :children [...]
)

instead of my initial :h-box/h-grow

The bind implementation is slightly hacky, and could be improved, but the real reason is that wanted to look whether a different API would be better. I'm not very happy with the dot notation, but otherwise have no better idea :) . A treeview for example looks like this:

(ui/tree-view
    :id :my-tree
    :listen/selection-model.selected-item {
        :event :node-selected
        :fn-fx/include {:my-tree [:selection-model.selected-item.value]}})

You can use the branch nested_properties and let me know if you encounter problems. It has everything master has.
