Question

approach to build a simple Calendar in Java Swing

Answer 1

+1 A:

You would probably want to think about using JTable. You can use an AbstractTableModel to define the dimensions of the table, as well as some other properties, then you can fill in the top row and first column with the desired values. You can also set certain parts of the table editable by your users, in the event that you wanted to be able to input data into the calendar.

For more info, take a look at the JTable documentation.

Don't do it! JTable sucks, particularly for rich content. I'd recommend using a JPanel with a GridLayout with JPanels for each panel. JTables approach of using renderers for each cell and switching to editors will be wholly innappropriate for a calendar component.

"Rich content"? The OP specified that each cell had to hold text, not images or anything else. I think using a JTable would be the simpler solution for this problem, given that there's no need to do the hard work of instantiating bunches of JPanels in a GridLayout then dealing with making them editable somehow.For rich content, yes, a bunch of JPanels might beat out a JTable. But for a plain text calendar, I don't see why a JTable is inappropriate.

True but they also mentioned that it should be similar to Google Calendar which goes way beyond JTable's functionality. Also JTable still sucks. What happens when the OP needs to change the cursor for a particular cell, add a mouseover effect, use wrapped text or have a complex editor containing more than one Component? They'll run into JTable's myriad of shortcomings.

Okey I will try them both and see which one fits my needs. I will need a mouse over effect and also actually a drag n drop functionallity to move events. It doesn't need to look good in any way, just work :)
