Re: Trouble integrating console code into GUI

TurboPT · #11 14-May-2008, 16:19

No problem.

Oh, the '3 to 2' button quit working because this was modified and left behind:

JAVA Code:

    gameButtons[5].setEnabled(false);  // disabled the button.

Thanks

[secondly]Im also having problems implementing my progress bar to work in auto mode if you know anything about those. Ive played around with it but just cant get it going. It looks like its initialised, but I just cant get it to increment. I was trying to make it go from 0 to optimum by getting the optimum number and increment the bar every move based on how far its got to go.
Lastly im having trouble with the reset button to play another game, ive made up a method called withdraw() on my main class and it basically is just popping numbers out of the linked list to clear the board but its not quite working properly. I'll print my main i've been

The third item ( the reset ) seems to be working. There were a few things needed.
I modified withdraw() to this: (requires a change in the peg class)

JAVA Code:

	public void withdraw(){
        try{
           	peg1.removeAll();
            peg2.removeAll();
            peg3.removeAll();
        }catch (Exception e){
		 	System.out.println("Error clearing pegs!: " + e);
        }
    }

...and to support that change, this function was added to the peg class:

JAVA Code:

public void removeAll() throws Exception
{
	while ( countPeg > 0 )
	{
		pop();
	}
}

... AND there are a few changes in the Main class, but I'll post that in a few moment(s), possibly in another post.

Will scrolling text be expected in the text window? Is this also where the vertical output is expected? (along with the other messages?)
Also there doesn't appear to be a label3 on the GUI?

Other than that, still looking at the first two items, and have an idea for the vertical print, but not sure where you are expecting it to be shown?

EDIT:
Oh, does the image you have fill that entire top area?

Nice work on the reset button, works like a charm.

Yes board and all messages on text pane, except for the number of discs choice and manual or auto mode, I like how you did that. Saves having an input on the gui.No scrolling isnt needed on the textpane. I was thining everytime there is a message it just re-displays it. And everytime there was a board change it just replaces what was on there. I dont mind either way though, which ever is easiest scrolling or not. Im sitting here working on it and ive been racking my brain for the last two days how to get the board displaying on the JTextPane but im failing everytime. So if you can get it doing that i'd be well impressed.

Still a work-in-progress, but here's the main class again...

The changes from your last post (when you posted this class) include:
1. buttons 7 & 8 have been added to the array
(see the 'titles' string, and function actionPerformed(), and #5, below )
2. Function reset() modifed
(removed loop -- change to withdraw() makes it unnecessary)
3. Added new function: newGame()
(called by the constructor, AND reset() )
4. Removed the statement that disabled the button.
5. Added commentary for the button array areas:
(see the 'titles' array, the 'button loop' [just after where the progress bar is colored], function actionPerformed(), and the section where the components are added to the content pane. )

Let me know if the reset works as expected (or not). I'll have to do more tomorrow -- out of time again!

Barman007 · #16 14-May-2008, 22:09

All good the resest button works perfectly. Assignment is due by this time tommorow just to give you a timeframe. No worries if you dont have time to help out anymore but just letting you know if you do anything you post after this time tommorow will be unuseable for me. Progress bar, printing vertically and printing to the gui screen are the only things left. Hopefully i'll have have solved atleast one of them by tommorow, but i'll post back and let you know how im going.

I know I sound like a broken record, but thanks again

Barman007 · #17 15-May-2008, 06:34

Just in case you get another chance to take a look for me I just worked out how to print vertically and ive nearly finished writing the code for that, I should have that complete before I go to sleep.

Now its just a matter of getting the board displaying on the JTextPane(which ive tried a million different ways but just cant crack it) and the progress bar.

:::::::::********EDIT***********:::::::::::::

Scratch that, I thought I had it lol. Its printing out the first board state ok, but after that it just dies.

Ok, well a few items needed, but here it is:

Elements for the llist class: (see the comments as to what's new)

JAVA Code:

StringBuffer nodeDataList = new StringBuffer(); // New: class variable.

public void printList() {
    nodeDataList.setLength(0); // New: clear the buffer, regardless
    printNode(head);
    System.out.println();
}

public void printNode(llnode node) {

    if (node != null) {
        nodeDataList.append( node.dataVal() + "," ); // New: append to buffer
        printNode(node.nextNode());
        System.out.print(node.dataVal() + " ");
    }
}

// New function: return the buffer as a string.
public String getDataList()
{
    return nodeDataList.toString();
}

New function for the peg class:

JAVA Code:

    public String getList()
    {
        return getDataList();
    }

New function for the board class:

JAVA Code:

// Build a string for vertical board display.
public String printBoardVertically( int numDiscs )
{
    StringBuffer verticalBoard = new StringBuffer();

    if ( numDiscs <= 0 ) // sanity check!
    {
        return "";
    }
    else
    {
        String[] p1 = null; // array for each peg.
        String[] p2 = null;
        String[] p3 = null;
        String place_holder = "-\t\t"; // no-value place holder.
        String value_spacer = "\t\t"; // keep alignment.
        int columnHeight = 0;

        /* Any peg containing value(s)
            1. print the peg (populates a buffer)
            2. get the buffer's string, and split into array.
        */
        if( peg1.countPeg() > 0 )
        {
            peg1.print();                   // #1
            p1 = peg1.getList().split(","); // #2
        }

        if( peg2.countPeg() > 0 )
        {
            peg2.print();
            p2 = peg2.getList().split(",");
        }

        if( peg3.countPeg() > 0 )
        {
            peg3.print();
            p3 = peg3.getList().split(",");
        }

        /*
            This loop will
            1. determine a reducing column height (applies to all pegs)
                This is to know if the 'height', so to speak, is larger
                than what an array contains.

            Then for each peg:
            2. is associated array null? append place holder
            3. column exceeds array size? append place holder
            4. otherwise, append array values with a value spacer.

            After each iteration of peg processing
            5. append newline.
        */
        for ( int i = 0; i < numDiscs; ++i )
        {
            columnHeight = numDiscs - i;        // #1

            if ( p1 == null )                   // #2
            {
                verticalBoard.append( place_holder );
            }
            else if ( columnHeight > p1.length )// #3
            {
                verticalBoard.append( place_holder );
            }
            else                                // #4
            {
                                        /* note the index calculation */
                verticalBoard.append( p1[p1.length - columnHeight] + value_spacer );
            }

            if ( p2 == null )                   // (#2 through #4 again)
            {
                verticalBoard.append( place_holder );
            }
            else if ( columnHeight > p2.length )
            {
                verticalBoard.append( place_holder );
            }
            else
            {
                verticalBoard.append( p2[p2.length - columnHeight] + value_spacer );
            }

            if ( p3 == null )                   // (#2 through #4 again)
            {
                verticalBoard.append( place_holder );
            }
            else if ( columnHeight > p3.length )
            {
                verticalBoard.append( place_holder );
            }
            else
            {
                verticalBoard.append( p3[p3.length - columnHeight] + value_spacer );
            }

            verticalBoard.append("\n");         // #5
       }

        System.out.println( verticalBoard.toString() );  // debug print
    }

    return verticalBoard.toString();
}

Finally, in the Main class, I made these changes:
Inside function processManual():

JAVA Code:

  // BEFORE the if, I left this in-place for debug
  bd.printBoardVertically(discNum); // leaving for console print

inside the 'else' portion, this line:

JAVA Code:

  display.setText ("So far you have made " + count +  " moves.\nPlease choose another peg move");

was modified to this:

JAVA Code:

  display.setText ("So far you have made " + count +
                   " moves.\nPlease choose another peg move" +
                   "\n" + bd.printBoardVertically(discNum) );

Inside function getMode(), in the 'if' portion, this line:

JAVA Code:

  display.setText("\nManual mode selected\n\nPlease enter your move\n\n\n");

was modified to this:

JAVA Code:

  display.setText("\nManual mode selected\nPlease enter your move\n\n" +
                 bd.printBoardVertically(discNum) );

Try it out, see how it works.
Here's sample output from the TextPane:
At start:

Code:

Manual mode selected
Please enter your move

1		-		-		
2		-		-		
3		-		-

Peg 1 to 3:

Code:

So far you have made 1 moves.
Please choose another peg move
-		-		-		
2		-		-		
3		-		1

A couple minor notes to know: (not problems, just expected behavior)
1. A vertical scroll bar appears with 5+ discs
2. When the #discs exceeds nine, the double digits make the columns appear slightly off-alignment.

(if not seen yet, check post #18 for the vertical print)

As to the progress bar...

Is the progress bar supposed to work in manual mode too? You only mentioned automatic.

Anyway, the automatic solver, being recursive that it is, within another class, there is not a way (as it stands right now) to make updates to the progress status, as it only returns after solving. Also, while in this recursive mode, there won't be a way to get regular board updates back to the GUI for display either.

I don't know how much time I'll get to look at this part today, but maybe this insight (if not already known) might give some insight as to what might need to be done for an alternative?
