How to draw a tree representing a graph of connected nodes?
(4 answers)
Closed 6 years ago.
Given a tree how one could approach to draw the same using Java Swing that what we draw in a simple piece of paper to understand a tree ? i.e. drawing all the nodes an values inside the node circle as well as threads to join the parents with the child and so on .The Structure will be like this :

You can use JavaFX for that:

That's the newest Java GUI technology!

I can't seem to have a grasp on OpenGL VAOs and VBOs.
I am coding an OBJ Loader from scratch (BTW I am using LWJGL) and I can't seem to get the order of normals correctly. When I look at the OBJ File I notice that there are positions with different normals and the face contains index numbers for position, texture, and normals. I don't know how to order them properly so that my normals would be assigned into correct positions when the engine starts rendering.

In javaFx, Why do we need to call "getChildren()" when we add an element to a window?
(3 answers)
Closed 5 years ago.
For example if I were to add a line of code such as-
hbox.getChildren().add(calculateButton);
what significance does .getChildren hold and what happens if it not used in a program?
getChildren method is used to get the children components(such as checkboxes, buttons etc) in a container.
In your case, hBox is a container which can contain buttons, spinners etc. So getChildren lists the current components in hBox.
It is basically a list of components currently present in the container. By using add() you are adding a new component in that list.

I will be building a program on how to construct a NFA , the output of this particular program is visualise out the NFA in a graphical user interface. The final output of the program must be something like this:
My question is how do I get started on "drawing" the states in circle , adding edges , inserting the input between two states, how do I program the GUI part by using java? please help me out..
Ty to look to https://github.com/jgraph/mxgraph. There is swing/web examples. Manual is here https://jgraph.github.io/mxgraph/.

Exporting JUNG graphs to hi-res images (preferably vector based)

I have an editable VisualizationViewer inside a GraphZoomScrollPane. After moving and reorganizing the graph I want to save the edited version into a image file.
When I tried using VisualizationImageServer it requires the layout which removes the modifications and set up the nodes to the original layout.
By printing the JPanel into the image, I only get the visible portion and I need the full image to be saved.
I'm not an expert on Jung, but this question seems to provide a workable approach to what you want to do:

Is there any Java data structure implementation similar to tree and graph?
Not in the java.util Collections API.
You can use the DefaultTreeModel from Swing for trees.
Jung is a graph framework.
As I answered for a similar question, the Java API contains no general API for trees/graphs, since there is no unique set of features needed in every usecase. There are quite some tree/graph-like APIs for special cases, though.
And in principle it is easy to make your own graph - one could even say that every object is in fact a node in a graph, with the values of its reference type fields being the (outgoing) neighbors.
