Various settings for the editor, defined at the time of initialization, or added at any time later in the program. Includes various geometric settings such as canvas dimensions and the gutter between nodes, and, in a later version of this package, more functional settings such as hiding placeholder nodes.
Sets the width of node.
Sets the width of the canvas.
Sets the height of the canvas.
Vertical distance between the bottom of a parent node and the top of its child.
Horizontal gutter between nodes.
When a node is activated, the interface centers it automatically. Sometimes, though, it is useful to move it somewhere other than the center, e.g. to accommodate a large pop-up underneath. With this configuration option, you can specify this offset, horizontal first, vertical second.
Stroke color of the lines connecting siblings.
Stroke width of the lines connecting siblings.
Enable or disable drag and drop with this boolean flag (True is enabled, which is the default value). Note that the tree can still be panned if drag and drop is disabled.
Set whether placeholder leaves should be displayed.
A fine-grained control version of showPlaceholderLeaves, allowing control on the display of placeholder leaves based on the contents of the node, as well as its parent and children.
Turn on mouse move throttling over a specified interval. You must connect subscriptions for this to work.
Enables sturdy mode: as long as the tree is not empty, there is always one active node. Use this mode when it is critical that active node-related feedback doesn't leave the screen.
Sets a default node to be created automatically when a child placeholder is clicked. If none is specified, the placeholder is activated so that a new node may be added manually.
Sets the width of node.
