    Default Phase one clean up! (windows style file loader/saver WANTED)

    Hi everyone! I finally have a nicely working version of my program and I am looking to clean up the file input/output.

    Currently I have used Strings, Files, and URLs, in a blended mess of concatenation, and though it all works perfectly,
    I need to expand in re-usability, and professionalism. My desire is to make your "Standard" file opener, exactly like say Microsoft word.
    The viewer will allow the user to look through the folder visually and select a file to load, as well as when saving see if they are saving
    over a file name already being used.

    If anyone knows of a good library that already has a class that does this, I would be extremely grateful, as putting together the GUI to do it from scratch seems almost as complex as my program itself.

    An example of the code I use currently to achieve these results:
        public CenterGrid(String fileName) {
            JPanel gridHolder = new JPanel();
     
            File file = new File(fileName); //Not responsible for checking for valid fileName. That is up to the loader.
            BufferedReader reader;
     
            // TODO: z CONVERTING URL EXAMPLE: (Project Aid)
            // System.getProperty("user.dir") = C:\Users\Jons\Desktop\TestFile Loading
            // curLineInfo                    = /Images/Terrain/Grass.png
            // URL NEEDS TO LOOK LIKE         = file:/C:/Users/Jons/Desktop/TestFile Loading/Images/Terrain/Grass.png       
            try {
                reader = new BufferedReader(new FileReader(file));
                String curLineInfo;
                myHeight = Integer.parseInt(reader.readLine());// TODO: x currently ignoring standard error checking. need to make sure everything is covered.
                myLength = Integer.parseInt(reader.readLine());// TODO: x currently ignoring standard error checking. need to make sure everything is covered.
                tiles = new Tile[myHeight*myLength]; //creates array long enough for the area of Tile objects.
     
                gridHolder.setLayout(new GridLayout(myHeight,myLength));
     
                int idx = 0;// keeps track of the array index
                while ((curLineInfo = reader.readLine()) != null) {// TODO: x currently ignoring standard error checking. need to make sure everything is covered.
                    Tile tile = new Tile();
                    String terrainStringURL = ("file:/" + System.getProperty("user.dir").replace('\\','/') + curLineInfo); //build curLineInfo into a useable URL
                    Terrain terrainFromFile = new Terrain(new URL(terrainStringURL), tile);
                    tile.addTerrain(terrainFromFile);
                    gridHolder.add(tile);
                    tiles[idx]=(tile);
                    idx++; 
                }
            } catch(FileNotFoundException e){} catch (IOException ex) {}// TODO: x currently ignoring standard error checking. need to make sure everything is covered.
     
            add(gridHolder);
            gridHolder.setVisible(true);
        }

    So I have sections of zoo like appearance I would prefer to clean up before I handle my programs ability to load multiple folders.
    I will write a class to clean up the "on the spot" code look, but before I do, I wanted to see if I could get the golden apple and instead
    get the windows style loader, and just rewrite to use that classes functionality instead.

    Hopefully I am being clear.

    I will post a .zip file that has the .jar and the folders needed to run the program so you can get a feel for what is is capable of.

    Thanks as always,
    Jonathan

    Default Re: Phase one clean up! (windows style file loader/saver WANTED)

    imported classes for my .jar program (attempting to ensure a malware free promise)
    import java.awt.*;
    import java.io.*;
    import java.net.*;
    import java.awt.event.*;
    import javax.swing.*;

    There are no infinite loops, or memory leaks.
    The program has no hidden agenda other then its very visual functionality.

    I have run it using windows 7 and JDK 7u3-nb-7_1 with netbeans 7.1.1-ml-javase

    it has the ability to make a large amount of JPanels, but I have caped the users input to 100x100, 10,000. the default is 20x30, 600.

    Currently the loader automatically loads test.txt from the Maps folder.
    I have not done any error checking involving a user creating bad data to load, but it will most certainly just result in the program not loading pictures to JPanels.

    If I could get some basic testing on other platforms that would be amazing.
    Thanks,
    Jonathan

    Perhaps I mis-undertand your requirements, but wouldn't a JFileChooser suffice?
