Virtualized Tree with TreeLayout
GoJS Features in this sample
Collections
GoJS provides its own collection classes: List, Set, and Map. You can iterate over a collection by using an Iterator. More information can be found in the GoJS learn pages.
Tree Layout
This predefined layout is used for placing Nodes of a tree-structured graph in layers (rows or columns). For discussion and examples of the most commonly used properties of the TreeLayout, see the learn Trees page. More information can be found in the GoJS learn pages.
Custom Layouts
GoJS allows for the creation of custom layouts to meet specific needs.
There are also many layouts that are extensions -- not predefined in the
go.js or go-debug.js library, but available as source code in
one of the three extension directories, with some documentation and corresponding
samples. More information can be found in the
GoJS learn pages.
ToolTips
A tooltip is an Adornment that is shown when the mouse hovers over an object that has its GraphObject.toolTip set. The tooltip part is bound to the same data as the part itself.
It is typical to implement a tooltip as a "ToolTip" Panel holding a TextBlock or a Panel of TextBlocks and other objects. Each "ToolTip" is just an "Auto" Panel Adornment that is shadowed, and where the border is a rectangular Shape with a light gray fill. However you can implement the tooltip as any arbitrarily complicated Adornment.
