I think, it is impossible to change that parent node in (<a href="http://www.java2s.com/Code/Java/Swing-JFC/CheckBoxNodeTreeSample.htm" rel="ugc">http://www.java2s.com/Code/Java/Swing-JFC/CheckBoxNodeTreeSample.htm</a><br />
) to a check box..it is my major requirement.<br />

Hi experts,<br />
I found the code which hopefully satisfies my requirements. The link is<br />

In that thread, &quot;MyBooleanTreeCellEditor&quot; is a perfect demo I presume(as certified by the users who posted in that thread).<br />
I tried creating check box nodes with &quot;MyBooleanTreeCellEditor&quot; as given in the code attached, but it does not work. Please help with any sample demo for using &quot;MyBooleanTreeCellEditor&quot; or by pointing out the error in the given code. <br />
Any help will be greatly appreciated.<br />
Thanks and regards,<br />

Your code doesn't set a TreeCellRenderer i don't think. It needs to

<div>
This app <a href="https://feedtrove.dev.java.net/" rel="ugc">https://feedtrove.dev.java.net/</a>&nbsp;use a checkbox editor and renderer and the source is here:<br />

Or just say how to convert the parent node in this code <a href="http://www.java2s.com/Code/Java/Swing-JFC/CheckBoxNodeTreeSample.htm" rel="ugc">http://www.java2s.com/Code/Java/Swing-JFC/CheckBoxNodeTreeSample.htm</a><br />
to a checkbox. <br />
The given link by CEHJ was more than helpful, but the only problem is that, I am not able to convert that parent node there to a check box. Else, I could have used that code straight away....<br />

Hi experts,<br />
I have a requirement. I have attached a self-explanatory image of my requirement. <br />
I need to have the exact tree structure shown there. To the left of each parent check box, '+' node should be shown, and upon expanding the parent node, the child nodes should be shown which should also be check box type-- THE CHILD NODE WOULD NEVER BE A PARENT NODE!! If I check the check box of parent node, then automatically all the child check boxes should get checked.<br />
How will I implement this?<br />
Any help will be greatly appreciated..<br />

Jtree with checkboxes

Development in most programming languages is frequently done with an editor or integrated development environment (IDE). An IDE is a software application that provide comprehensive facilities to computer programmers for software development. An IDE normally consists of a source code editor, build automation tools and a debugger. XCode, Visual Studio, Adobe Dreamweaver and Eclipse are some of the more popular development tools, but an editor or IDE can be anything from simple text editors to sophisticated programs.

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.

Programming theory deals with the design, implementation, analysis, characterization, and classification of programming languages and their individual features, along with introductory programming concepts like program structure, variable declaration and conditional and looping constructs. Sub-disciplines include the formal semantics of programming languages, type theory, program analysis and transformation, comparative programming language analysis, metaprogramming, domain-specific languages, compiler construction and run-time systems.
