  • Java - How can I edit the size and position of a button using Swing?

    - by mino
    I have the following code but I'd like to structure several buttons of certain sizes. I'm just wondering how to do this as I've Googled it and found several different methods but none seem to work. Any advice? import javax.swing.*; public class GUI { public static void main(String[] args) { JFrame window = new JFrame(); window.setSize(500, 500); window.setTitle("My Application"); JButton button = new JButton("click me"); window.add(button); window.setVisible(true); } }

  • How do we simplify this kind of code in Java? Something like macros in C?

    - by Terry Li
    public static boolean diagonals(char[][] b, int row, int col, int l) { int counter = 1; // because we start from the current position char charAtPosition = b[row][col]; int numRows = b.length; int numCols = b[0].length; int topleft = 0; int topright = 0; int bottomleft = 0; int bottomright = 0; for (int i=row-1,j=col-1;i>=0 && j>=0;i--,j--) { if (b[i][j]==charAtPosition) { topleft++; } else { break; } } for (int i=row-1,j=col+1;i>=0 && j<=numCols;i--,j++) { if (b[i][j]==charAtPosition) { topright++; } else { break; } } for (int i=row+1,j=col-1;i<=numRows && j>=0;i++,j--) { if (b[i][j]==charAtPosition) { bottomleft++; } else { break; } } for (int i=row+1,j=col+1;i<=numRows && j<=numCols;i++,j++) { if (b[i][j]==charAtPosition) { bottomright++; } else { break; } } return topleft + bottomright + 1 >= l || topright + bottomleft + 1 >= l; //in this case l is 5 } After I was done posting the code above here, I couldn't help but wanted to simplify the code by merging the four pretty much the same loops into one method. Here's the kind of method I want to have: public int countSteps(char horizontal, char vertical) { } Two parameters horizontal and vertical can be either + or - to indicate the four directions to walk in. What I want to see if possible at all is i++; is generalized to i horizontal horizontal; when horizontal taking the value of +. What I don't want to see is if or switch statements, for example: public int countSteps(char horizontal, char vertical) { if (horizontal == '+' && vertical == '-') { for (int i=row-1,j=col+1;i>=0 && j<=numCols;i--,j++) { if (b[i][j]==charAtPosition) { topright++; } else { break; } } } else if (horizontal == '+' && vertical == '+') { for (int i=row+1,j=col+1;i>=0 && j<=numCols;i++,j++) { if (b[i][j]==charAtPosition) { topright++; } else { break; } } } else if () { } else { } } Since it is as tedious as the original one. Note also that the comparing signs for the loop condition i>=0 && j<=numCols; for example, >= && <= have correspondence with the value combination of horizontal and vertical. Sorry for my bad wording, please let me know if anything is not clear.

  • Is there a a C-like way to get item number from enum in java ?

    - by Hernán Eche
    Perhap this is a simple basic question Having an enum public enum TK{ ID,GROUP,DATA,FAIL; } Can I get the order number for example ID=0, GROUP=2, DATA=3, FAIL=4 ? This is a way to to that, but a weird and long one! =S public enum TK{ ID(0),GROUP(1),DATA(2),FAIL(3); int num; TK(int n) { this.num=n; } public int get() { return num; } }; to get numbers so I write TK.ID.get(), TK.GROUP.get(), etc... I don't like that there is a better way? ( C enums, C macros..I miss you both ) thanks

  • Compiling CSS to SWF server side Java, What is the best practice?

    - by DataSurfer
    My project allows users to create custom css for our flex app. In regards to compiling the CSS into SWFs on the server side: Should I use the flex2.compiler.css.Compiler class in mxmlc-3.5.0.12683.jar? Or Should I invoke mxmlc from Runtime.getRuntime().exec()? The css.Compiler class is not very well documented. Does anyone have any examples that use this? For the Runtime exec method, what is the best way to package mxmlc into the maven build so its available to the server at runtime?

  • How to proceed jpeg Image file size after read--rotate-write operations in Java?

    - by zamska
    Im trying to read a JPEG image as BufferedImage, rotate and save it as another jpeg image from file system. But there is a problem : after these operations I cannot proceed same file size. Here the code //read Image BufferedImage img = ImageIO.read(new File(path)); //rotate Image BufferedImage rotatedImage = new BufferedImage(image.getHeight(), image.getWidth(), BufferedImage.TYPE_3BYTE_BGR); Graphics2D g2d = (Graphics2D) rotatedImage.getGraphics(); g2d.rotate(Math.toRadians(PhotoConstants.ROTATE_LEFT)); int height=-rotatedImage.getHeight(null); g2d.drawImage(image, height, 0, null); g2d.dispose(); //Write Image Iterator iter = ImageIO.getImageWritersByFormatName("jpeg"); ImageWriter writer = (ImageWriter)iter.next(); // instantiate an ImageWriteParam object with default compression options ImageWriteParam iwp = writer.getDefaultWriteParam(); try { FileImageOutputStream output = null; iwp.setCompressionMode(ImageWriteParam.MODE_EXPLICIT); iwp.setCompressionQuality(0.98f); // an integer between 0 and 1 // 1 specifies minimum compression and maximum quality File file = new File(path); output = new FileImageOutputStream(file); writer.setOutput(output); IIOImage iioImage = new IIOImage(image, null, null); writer.write(null, iioImage, iwp); output.flush(); output.close(); writer.dispose(); Is it possible to access compressionQuality parameter of original jpeg image in the beginning. when I set 1 to compression quality, the image gets bigger size. Otherwise I set 0.9 or less the image gets smaller size. How can i proceed the image size after these operations? Thank you,

  • .NET user interface components recommendations

    - by Parakus
    I'm looking for advice on what .NET user interface components are out there on the market. I have been developing asp.net websites and have mainly been using the Visual studio toolbox build in controls supported by the AjaxcontrolToolkit and the applications have been mainly used inhouse running on our company intranet. But now a new client wants a much more professional looking, commercial web application and they have a budget for some user components for use in the application. Any recommendations where value for money will be realised. Interested in components that will integrate well with ASP.NET 3.5 SP1 or even .NET 4.

  • Is an ArrayList automaticaly declared static in Java, if it is an instance variable?

    - by Alex
    I'm trying to do something like this: private class aClass { private ArrayList<String> idProd; aClass(ArrayList<String> prd) { this.idProd=new ArrayList<String>(prd); } public ArrayList<String> getIdProd() { return this.idProd; } } So if I have multiple instances of ArrayLIst<String> (st1 ,st2 ,st3) and I want to make new objects of aClass: { aClass obj1,obj2,obj3; obj1=new aClass(st1); obj2=new aClass(st2); obj3=new aClass(st3); } Will all of the aClass objects return st3 if I access the method getIdProd() for each of them(obj1..obj3)? Is an ArrayList as an instance variable automatically declared static?

  • How Two Programs Can Talk To Each Other In Java?

    - by Arnon
    My first time here... I want to ?reduce? the CPU usage/ROM usage/RAM usage - in general ?speaking?, all system resources that my App use - how doesn't? :) For this reason i want to split the preferences window from the rest of the application, and let the preferences window to run as ?independent? program. The preferences program ?should? write to a Property file(not a problem at all) and to send a "update signal" to the main program - which mean, to call the update method(that i wrote) that found in the Main class. How can i call the update method in the Main program from the preferences program? Or in the other hand... There is a way to build preferences window that take system resources just when it's appear? Is this approach - of separating programs and let them talk to each other(somehow) - is a right approach for speeding up my programs? tnx

  • Interface -> Entity Mapping

    - by KiD0M4N
    Hi guys, Suppose I have a few definitions like so: public interface ICategory { int ID { get; set; } string Name { get; set; } ICategory Parent { get; set; } } public class Category : ICategory { public virtual int ID { get; set; } public virtual string Name { get; set; } public virtual ICategory Parent { get; set; } } How do I map such a scenario in NHibernate? I am trying to separate the implementation of the DAL. I am learning NHibernate. Regards, Karan

  • How to implement a collection (list, map?) of complicated strings in Java?

    - by Alex Cheng
    Hi all. I'm new here. Problem -- I have something like the following entries, 1000 of them: args1=msg args2=flow args3=content args4=depth args6=within ==> args5=content args1=msg args2=flow args3=content args4=depth args6=within args7=distance ==> args5=content args1=msg args2=flow args3=content args6=within ==> args5=content args1=msg args2=flow args3=content args6=within args7=distance ==> args5=content args1=msg args2=flow args3=flow ==> args4=flowbits args1=msg args2=flow args3=flow args5=content ==> args4=flowbits args1=msg args2=flow args3=flow args6=depth ==> args4=flowbits args1=msg args2=flow args3=flow args6=depth ==> args5=content args1=msg args2=flow args4=depth ==> args3=content args1=msg args2=flow args4=depth args5=content ==> args3=content args1=msg args2=flow args4=depth args5=content args6=within ==> args3=content args1=msg args2=flow args4=depth args5=content args6=within args7=distance ==> args3=content I'm doing some sort of suggestion method. Say, args1=msg args2=flow args3=flow == args4=flowbits If the sentence contains msg, flow, and another flow, then I should return the suggestion of flowbits. How can I go around doing it? I know I should scan (whenever a character is pressed on the textarea) a list or array for a match and return the result, but, 1000 entries, how should I implement it? I'm thinking of HashMap, but can I do something like this? <"msg,flow,flow","flowbits" Also, in a sentence the arguments might not be in order, so assuming that it's flow,flow,msg then I can't match anything in the HashMap as the key is "msg,flow,flow". What should I do in this case? Please help. Thanks a million!
