Using Java Swing: Which Components to use

[burung]

Hi,

I need a guide here. I want to develop a program to simulate a simple logic circuit (AND, OR, NAND, NOR, XOR, XNOR gates). Here are the properties of the program.( These gates are images):

• There is a dialog box containing all the gates where I can select which gate to use and drag it onto the display area.
• The gates on the display area can be connected through lines.
• The circuit can accept input bits
• The circuit can compute the output bits given the input bits
• I can open an input file (probably XML) that contains a circuit and display it on the display area and run simulation on it.

So, what Java Swing components that I can use to display the circuit?

What component of Java Swing that support XML file manipulation?

Any other advice ??

Thank you.

Check out JGraph for some Swing components.

I would just use the standard Java XML APIs to process the XML file. There is no need for a visual component to do this. Other than maybe a open file dialog.

I'll check on JGraph. At least I have some hint to proceed. Thanks.

Do you mean using SAX.. or is it DOM for the XML?

Thank you...

Either. I usually map XML to objects now. With something like Castor. Processsing a XML is not fun. I try not to do it by hand any more.
