TreeTable is an extension of the Table component with support for a tree-like hierarchy in the first column. As with Treethe hierarchy is determined by the parent-children relationships defined in the Container. Hierarchical interface. The default container is HierarchicalContainerbut you can bind TreeTable to any container implementing the interface.
As with Treeyou can define the parent-child relationships with setParentas is shown in the following example with numeric item IDs:. Some container types may allow defining hierarchies if the container data itself, without explicitly setting the parent-child relationships with setParent. These containers should be used if there is going to be a lot of data. Setting up a Container. Hierarchical before setting it to the TreeTable will improve the initial performance.
Unlike Treea TreeTable can have components in the hierarchical column, both when the property type is a component type and when the tree table is in editable mode.
For other features, we refer you to documentation for Table in Table and Tree in Tree. Note that if you want to expand all items, there is no expandItemsRecursively like in Tree.
Moreover, the getItemIds only returns the IDs of the currently visible items for ordinary Hierarchical not Collapsible containers. Hence you can not use that to iterate over all the items, but you need to get the IDs from the underlying container.
In large tables, this explicit setting becomes infeasible, as it needs to be stored in the TreeTable more exactly, in the HierarchicalStrategy object for all the contained items. You can use a Collapsible container to store the collapsed states in the container, thereby avoiding the explicit settings and memory overhead.
There are no built-in collapsible containers in the Vaadin core framework, so you either need to use an add-on container or implement it yourself. Project starters Create a new project.
Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. How can I expand a particular node in code for example in onNodeSelect callback? There is a property expanded for TreeNodeall you need to do is just set it to true. And if you want the tree to be shown all expanded, just traverse the TreeNodes and set expanded on each. Which will be something similar to this. Learn more. Asked 3 years, 10 months ago.

TreeNode instance which corresponds to the root. Following below simple example that you may develop in which a Tree component had used. When node is expanded, tree loads the children of the particular expanded node and send to the client for display.
Unlike what is happened originally, when toggling is set to client all the tree nodes in model are rendered to the client and tree is created. For large scale of data the dynamic mode is suitable than using the default behavior. Following below the way in which dynamic attribute can be identified. For implementing this, you should follow below simple steps:. Following below simple example demonstration for using different TreeNode for showing that type varieties.
The files have affected by are both files index. As obvious from provided demo, the integration between TreeNode instance and p:treeNode component is the type attribute. Tree component provides a built-in functionality that help you identify those selected nodes. Following example is a log messages have displayed once onNodeClick has called.
Tree nodes can be reordered within a single tree and can even be transferred between multiple trees using dragdrop. Following example shows you how can make single tree draggable and droppable. Applying drag-drop concept against single tree is so easy, more complicated example can be noticed when it comes for dragging-dropping against multiple tree components.
Following example shows you a simple example for that. Default orientation of tree is vertical, setting it to horizontal displays nodes in a horizontal layout. All features of vertical tree except dragdrop are available for horizontal tree as well. Attribute orientation is used for this purpose. Primefaces provides you a special component that can serve you achieve some sort of contextual operations.
Use Right click for displaying context menu component.Till now we have seen how we can create some basic angular apps, from now on we will look for great component libraries. In this article we will be using primeng with angular 4. It would be great to go through angular material tutorial before this.
Although the official website explains how to install and use it, I am taking our own apps forwards to use primeng UI component library. Now, we want to use primeng in our bikes app. So include it in package. Note that DataListModule is imported here also.
These configurations are required for using primeng with angular 4. We will use the list component to render list of bikes as usual. We are using primeng with angular 4 in above template. These are the only changes required in addition to our previous angular material tutorial. Prasad Kharkar is a java enthusiast and always keen to explore and learn java technologies.
