TreeController | TreeController for iOS written on Swift | iOS library

I want to implement drag and drop with NSOutlineView similar Mac Finder application. With my current implementation, drag and drop session validates drop to children of each parent. I don't want that. I only want to drop child from one parent to another parent. like moving file from one folder to another folder in Finder. How to do that? below is a sample code with my drag and drop code included.

I use a NSOutlineView bound to a NSTreeController. I successfully managed to sort all columns of the view, except one! This column displays a button that is enabled if the binaryData field is not nil. The binaryData field in the model is a relationship to a MyBinary NSManagedObject subclass which has a NSData? field. I use this method (a relationship) as recommended to avoid loading all NSData in memory even when not necessary.

I want this column to be sortable, and, when clicked, have all enabled buttons regrouped (ascending or descending order), and all disabled buttons regrouped.

In IB, like other columns, I bound the column value to:

• Controller Key = arrangedObjects
• Model Key Path = binaryData

But when I click on the column, I have the following stack:

I am trying to implement a dynamic tree structure in primefaces where the user starting from a root node, will be able to add siblings and children into each node through two commandButtons.

Example shown below:

Root

After add sibling pressed

After add child pressed (2 times)

Following this, I have implemented the following structure:

tree.xhtml

I have the following in the TreeController controller in a small web API:

I have a TreeView and the GridPane contains multiple Nodes like Buttons and Labels. The amount of nodes inside the GridPane varies.

I need the cell factory to get the MouseEntered event but when I use the code below then no content gets displayed.

My current code looks like that:

I have written javascript code which takes the file with a json entry as an input and generates tree structure for same. Following is the fiddle for same :

you can test it by giving the following file as an input

Now I want to make this tree structure collapsible so that nodes in this json can expand/collapse. For implementing this I am referring code at:

Basic Collapsible

I have also tried using this basic collapsible feature, following is the code for same :

HTML

What I am trying to accomplish is to return an entity in a ManyToOne relationship and also do the reverse and returns the entities in a OneToMany relationship using Doctrine ORM.

For example if I have two entities Tree and Branch, it's fairly trivial to use Doctrine mapping to query for a particular tree and get a list of its branches (Where the relationship is one tree -> many branches)

Tree Entity

In a Laravel 5.6 app I have a controller managing a product tree. The getTree() method is building up the tree from the db, the updateTree() modifies it. Both methods are called via ajax accepting Request parameters:

I have a split screen HTML page. There are three DIVs in a horizontal flex layout, with a left and right pane for content. The button bar on the left pane is set at 100% width, but it's overflowing the parent element. What could be the cause of this?
