  • SWT TabFolder: Weird Drawing Behaviour

    - by JesperGJensen
    Hello StackOverflow Experts Description I have an SWT Page with a TabFolder with a number of dynamically created TabItems. On each TabItem i crate a Composite and set the TabItem.setControl() to the Composite. I then use this Composite as the page on which i draw my items. I draw a set of Controls, including Textbox's and Labels. For the First, Default Tab, this works fine. No problems. Problem On tabs that is not the first tab i have the following problems: I am unable to visually alter then Edited/Enabled state of my Controls. I am unable to visually set the Text content of my elements My Controls look disabled and have a Greyed out look. But i am able to Select the content with my mouse and use CTRL+C to copy it out. So the text contet is there and they are Editable. Visually it is just not updated. Any comments are appeciated, Any requests for code, examples will be supplied and help Welcommed. Updates I tried added the suggest debug loop to the code, where i attempt to enable my Controls. This was the result: [main] INFO [dk.viking.controller.LayerController] - f038.stklok is now Editable [true] and enabled [true] [main] INFO [dk.viking.controller.LayerController] - true Text {} [main] INFO [dk.viking.controller.LayerController] - true Composite {} [main] INFO [dk.viking.controller.LayerController] - true TabFolder {} [main] INFO [dk.viking.controller.LayerController] - true Shell {Viking GUI}

  • Hibernate query for multiple items in a collection

    - by aarestad
    I have a data model that looks something like this: public class Item { private List<ItemAttribute> attributes; // other stuff } public class ItemAttribute { private String name; private String value; } (this obviously simplifies away a lot of the extraneous stuff) What I want to do is create a query to ask for all Items with one OR MORE particular attributes, ideally joined with arbitrary ANDs and ORs. Right now I'm keeping it simple and just trying to implement the AND case. In pseudo-SQL (or pseudo-HQL if you would), it would be something like: select all items where attributes contains(ItemAttribute(name="foo1", value="bar1")) AND attributes contains(ItemAttribute(name="foo2", value="bar2")) The examples in the Hibernate docs didn't seem to address this particular use case, but it seems like a fairly common one. The disjunction case would also be useful, especially so I could specify a list of possible values, i.e. where attributes contains(ItemAttribute(name="foo", value="bar1")) OR attributes contains(ItemAttribute(name="foo", value="bar2")) -- etc. Here's an example that works OK for a single attribute: return getSession().createCriteria(Item.class) .createAlias("itemAttributes", "ia") .add(Restrictions.conjunction() .add(Restrictions.eq("ia.name", "foo")) .add(Restrictions.eq("ia.attributeValue", "bar"))) .list(); Learning how to do this would go a long ways towards expanding my understanding of Hibernate's potential. :)

  • Locating multiple nested If statements using regular expressions

    - by TERACytE
    Is there a way to search for multiple nested if statements in code using a regular expression? For example, an expression that would locate an instance of if statements three or more layers deep with different styles (if, if/else, if/elseif/else): if (...) { <code> if (...) { <code> if (...) <code> } else if (...) { <code> } else { <code> } } else { <code> }

    - by Vladimir
    Can anyone explain me what's wrong with the following code? I tried different hosts, FTPClientConfigs, it's properly accessible via firefox/filezilla... FTPClientConfig config = new FTPClientConfig(FTPClientConfig.SYST_L8); FTPClient client = new FTPClient(); client.configure(config); client.connect("c64.rulez.org"); client.login("anonymous", "anonymous"); client.enterRemotePassiveMode(); FTPFile[] files = client.listFiles(); Assert.assertTrue(files.length > 0);

  • Why is my file being cleared if I don't save it?

    - by Kat
    My program is suppose to maintain a collection of Photos in a PhotoAlbum. It begins by reading a folder of photos and adds them to my PhotoAlbum. It then prints a menu that allows the user to list all the photos, add a photo, find a photo, save, and quit the program. Right now if I run my program it will add the 100 photos to the PhotoAlbum, but if I quit the program without saving, it clears the file I am reading from even if I haven't added a photo or done anything to the PhotoAlbum and I'm not sure why. Here is my method for printing to a file: private static void saveFile(PrintWriter writer) { String result; ArrayList<Photo> temp = album.getPhotoAlbum(); for (int i = 0; i < temp.size(); i++){ result = temp.get(i).toString() + "\n"; writer.println(result); } writer.close(); } And where the PrintWriter is instantiated: File file = new File(args[0] + File.separator + "album.dat"); try { PrintWriter fout = new PrintWriter(new FileWriter(file)); fileWriter = fout; } catch (IOException e){ System.out.println("ReadFromFile: Folder " + args[0] + " is not found."); System.exit(0); } And where it is called in my runMenu Method: private static void runMainMenu(Scanner scan) { String input; do { showMainMenu(); input = scan.nextLine().toLowerCase(); switch (input.charAt(0)) { case 'p': System.out.println(album.toString()); break; case 'a': album.addPhoto(readPhoto(scan, t)); break; case 'f': findMenu(scan); break; case 's': saveFile(fileWriter); System.exit(0); break; case 'q': break; default: System.out.println("Invalid entry: " + input.charAt(0)); break; } } while (!input.equalsIgnoreCase("q")); }

  • JCo | How to iterate column wise

    - by cedar715
    The data from SAP is returned as a JCo.Table. However, we don't want to display ALL the columns in the VIEW. So, what we have done is, we have created a file called display.xml which has the JCO.Table columns to be displayed. The display.xml is converted to a List and each field is verified if it is present in the display list(see the code below) which is redundant from second row onwards. final Table outputTable = jcoFunction.getTableParameterList(). getTable("OUTPUT_TABLE"); final int numRows = outputTable.getNumRows(); for (int i = 0; i < numRows; i++) { final FieldIterator fields = outputTable.fields(); while (fields.hasNextFields()) { final JCO.Field recordField = fields.nextField(); final String sapFieldName = recordField.getName(); final DisplayFieldDto key = new DisplayFieldDto(sapFieldName); if (displayFields.contains(key)) { System.out.println("recordField.getName() = " + recordField.getName()); final String sapFieldName = (String)recordField.getValue(); } else { // ignore the field. } } } What is the better way to filter the fields in JCo? Can I iterate column wise? Thank you :)

  • How would I set up this enum to return the image I want?

    - by Justen
    I'm trying to set up this enum so that it has the ability to return the correct image, though I'm struggling with a way to incorporate the context since it is in a separate class. public enum CubeType { GREEN { public Drawable getImage() { return Context.getResources().getDrawable( R.drawable.cube_green ); } }; abstract public Drawable getImage(); } The error I'm getting is: Cannot make a static reference to the non-static method getResources() from the type Context

  • How do I write JPA QL statements that hints to the runtime to use the DEFAULT value ?

    - by Jacques René Mesrine
    I have a table like so: mysql> show create table foo; CREATE TABLE foo ( network bigint NOT NULL, activeDate datetime NULL default '0000-00-00 00:00:00', ... ) In the domain object, FooVO the activeDate member is annotated as Temporal. If I don't set activeDate to a valid Date instance, a new record is inserted with NULLs. I want the default value to take effect if I don't set the activeDate member. Thanks.

  • File.mkdir is not working and I can't understand why

    - by gotch4
    Hello, I've this brief snippet: String target = baseFolder.toString() + entryName; target = target.substring(0, target.length() - 1); File targetdir = new File(target); if (!targetdir.mkdirs()) { throw new Exception("Errore nell'estrazione del file zip"); } doesn't mattere if I leave the last char (that is usually a slash). It's done this way to work on both unix and windows. The path is actually obtained from the URI of the base folder. As you can see from baseFolder.toString() (baseFolder is of type URI and is correct). The base folder actually exists. I can't debug this because all I get is true or false from mkdir, no other explanations.The weird thing is that baseFolder is created as well with mkdir and in that case it works. Now I'm under windows. the value of target just before the creation of targetdir is "file:/C:/Users/dario/jCommesse/jCommesseDB" if I cut and paste it (without the last entry) in windows explore it works...

  • Is dependency injection possible for JSP beans?

    - by kazanaki
    This may be a long shot question.. I am working on an application that is based on JSP/Javascript only (without a Web framework!) Is there a way to have depencency injection for JSP beans? By jsp beans I mean beans defined like this <jsp:useBean id="cart" scope="session" class="session.Carts" /> Is there a way/library/hack to intercept the bean creation so that when "cart" is referenced for the first time, some some of injection takes place? Can I define somewhere a "listener" for JSP beans (like you can do for JSF beans for example)? I am free to do anything I want in the back-end, but I cannot add a web framework in the front-end (Don't ask!)

  • Android - Correspondence between ImageView coordinates and Bitmap Pixels

    - by Matteo
    In my application I want the user to be able to select some content of an Image contained inside an ImageView. To select the content I subclassed the ImageView class making it implement the OnTouchListener so to draw over it a rectangle with borders decided by the user. Here is an example of the result of the drawing (to have an idea you can think of it as when you click with the mouse on your desktop and drag the mouse): Now I need to determine which pixels of the Bitmap image correspond to the selected part. It's kind of easy to determine which are the points of the ImageView belonging to the rectangle, but I don't know how to get the correspondent pixels, since the ImageView has a different aspect ratio than the original image. I followed the approach described especially here, but also here, but am not fully satisfied because in my opinion the correspondence made is 1 on 1 between pixels and points on the ImageView and does not give me all the correspondent pixels on the original image to the selected area. Calling hoveredRect the rectangle on the ImageView the points inside of it are: class Point { float x, y; @Override public String toString() { return x + ", " + y; } } Vector<Point> pointsInRect = new Vector<Point>(); for( int x = hoveredRect.left; x <= hoveredRect.right; x++ ){ for( int y = hoveredRect.top; y <= hoveredRect.bottom; y++ ){ Point pointInRect = new Point(); pointInRect.x = x; pointInRect.y = y; pointsInRect.add(pointInRect); } } How can I obtain a Vector<Pixels> pixelsInImage containing the correspondent pixels?

  • Correct way to Convert 16bit PCM Wave data to float

    - by fredley
    I have a wave file in 16bit PCM form. I've got the raw data in a byte[] and a method for extracting samples, and I need them in float format, i.e. a float[] to do a Fourier Transform. Here's my code, does this look right? I'm working on Android so javax.sound.sampled etc. is not available. private static short getSample(byte[] buffer, int position) { return (short) (((buffer[position + 1] & 0xff) << 8) | (buffer[position] & 0xff)); } ... float[] samples = new float[samplesLength]; for (int i = 0;i<input.length/2;i+=2){ samples[i/2] = (float)getSample(input,i) / (float)Short.MAX_VALUE; }

  • Hierarchical object model with property inheritance and event bubbling?

    - by Winston Fassett
    I'm writing a document-based client application and I need a DOM or WPF-like, but non-visual model that: Is a tree composed of elements Can accept an unlimited number of custom properties that get/set any CLR type, including collections. Can inherit their values from their parent Can inherit their default values from an ancestor Can be derived/calculated from other properties, ancestors, or descendants Support event bubbling / tunneling There will be a core set of properties but other plugins may add their own or even create custom documents Supports full inspection by the owning document in order to persist the tree and attributes in an XML format. I realize that's a tall order but I was really hoping there would be something out there to help me get started. Unfortunately WPF DependencyObjects are too closed, proprietary, and coupled to WPF to be of any use as a document model. My needs also have a strong resemblance to the HTML DOM but I haven't been able to find any clean DOM implementations that could be decoupled from HTML or ported to .NET. My current platform is .NET/C# but if anyone knows of anything that might be useful for inspiration or embedding, regardless of the platform, I'd love to know.
