    <p>I made a peg solitaire game a few years ago which was pretty much just a JPanel that extended MouseListener and MouseMotionListener. The pegs were primitive circles drawn in the paint method, but you could track where they landed by taking the cursor position and mathematically working out the square in which it landed. That lined up with an array that stored either a 1 or 0 for each square on the board depending if anything was there. You could also drag each piece by finding the current cursor position then calling repaint() in the mouseDragged method you get from implementing MouseMotionListener.</p> <p>I'd probably suggest doing it that way to begin with. Create an array of whatever size and use that to track the units. Then each time you make a move just check that array and redraw your units in the paint method. If you're using mouse movement then you can get the current position of the unit on mouseDown then do what I mentioned before with mouseDragged, and then get your final location on mouseUp and also do your calculations in regards to legal moves etc in mouseUp. </p> <p>In the paint method you'll just loop over the array that defines the map and if there is a unit at the current position on the array then do something like g.fillOval(x,y,x_dimension,y_dimension). That array could just have its elements set to 0 for no unit at the current position, or 1 for a team 1 unit at the current position, 2 for team 2 etc. The paint method will take those numbers and draw pieces accordingly (change color for each type or whatever).</p> <p>I hope that makes a bit of sense.</p>

    1. COAnd if i want to have each unit self aware (for example, when clicked), how would you do that?

    2. COInstead of having an array of integers storing basic information on what is where you could have an array of unit objects. Just create a class called Unit or something, then inside that class have everything you want to store about each unit. You could even keep a similar integer array as well, just to check if something is a unit or a square of terrain. Depends on how you want to code it I guess.

    3. COInside each unit object you could have a boolean for whether it's active or not (which is turned on when you click that coordinate), then somewhere you could have a check for this, and then some sort of automated action could happen for example. Again it's up to you. Having an array of objects is quite powerful for this kind of stuff cos there is so much you can do with it.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
