  • 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}

  • Is there anyway to exclude artifacts inherited from a parent POM?

    - by Miguel
    Artifacts from dependencies can be excluded by declaring an <exclusions> element inside a <dependency> But in this case it's needed to exclude an artifact inherited from a parent project. An excerpt of the POM under discussion follows: <project> <modelVersion>4.0.0</modelVersion> <groupId>test</groupId> <artifactId>jruby</artifactId> <version>0.0.1-SNAPSHOT</version> <parent> <artifactId>base</artifactId> <groupId>es.uniovi.innova</groupId> <version>1.0.0</version> </parent> <dependencies> <dependency> <groupId>com.liferay.portal</groupId> <artifactId>ALL-DEPS</artifactId> <version>1.0</version> <scope>provided</scope> <type>pom</type> </dependency> </dependencies> </project> base artifact, depends on javax.mail:mail-1.4.jar, and ALL-DEPS depends on another version of the same library. Due to the fact that mail.jar from ALL-DEPS exist on the execution environment, although not exported, collides with the mail.jar that exists on the parent, which is scoped as compile. A solution could be to rid off mail.jar from the parent POM, but most of the projects that inherit base, need it (as is a transtive dependency for log4j). So What I would like to do is to simply exclude parent's library from the child project, as it could be done if base was a dependency and not the parent pom: ... <dependency> <artifactId>base</artifactId> <groupId>es.uniovi.innova</groupId> <version>1.0.0</version> <type>pom<type> <exclusions> <exclusion> <groupId>javax.mail</groupId> <artifactId>mail</artifactId> </exclusion> </exclusions> </dependency> ...

  • Yet another Ant + JUnit classpath problem

    - by user337591
    Hi, I'm developing an Eclipse SWT application using Eclipse. There are also some JUnit 4 tests, which test some DAO's. But when I try to run the tests via an ant build, all of the tests fail, because the test classes aren't found. Google brought up about a million of people who all have the same problem, but none of their solutions seem to work for me -.- . These are the contents of my build.xml file: <property name="test.reports" value="./test/reports" /> <property name="classes" value="build" /> <path id="project.classpath"> <pathelement location="${classes}" /> </path> <target name="testreport"> <mkdir dir="${test.reports}" /> <junit fork="yes" printsummary="no" haltonfailure="no"> <batchtest fork="yes" todir="${test.reports}" > <fileset dir="${classes}"> <include name="**/Test*.class" /> </fileset> </batchtest> <formatter type="xml" /> <classpath refid="project.classpath" /> </junit> <junitreport todir="${test.reports}"> <fileset dir="${test.reports}"> <include name="TEST-*.xml" /> </fileset> <report todir="${test.reports}" /> </junitreport> </target> The test classes are in the build-directory together with the application classes, although they are in some subfolders according to their packages. Maybe this is important too: At first Ant complained that JUnit wasn't in its classpath, but since I put it there (with the eclipse configuration editor) it complains about JUnit being in its classpath twice. WARNING: multiple versions of ant detected in path for junit [junit] jar:file:C:/Users/as df/Documents/eclipse/plugins/org.apache.ant_1.7.1.v20090120-1145/lib/ant.jar!/org/apache/tools/ant/Project.class [junit] and jar:file:/C:/Users/as%20df/Documents/eclipse/plugins/org.apache.ant_1.7.1.v20090120-1145/lib/ant.jar!/org/apache/tools/ant/Project.class I've tried specifying each and every subdirectory, each and every class file, I've tried filesets and filelists, nothing seems to work. Thanks for your help, I've been sitting for hours on this thing now...

  • Annoying struts 2 problem

    - by Parhs
    Hello... I am using this code to include some menus to my code... <s:action namespace="/" name="get_header" executeResult="true" /> <jsp:include page="/get_menu" > <jsp:param name="menuKey" value="configuration"></jsp:param> <jsp:param name="subMenuKey" value="user.add"></jsp:param> </jsp:include> THe problem is that the menus are generated dynamically... So suppose that we have 2 Actions ActionA and get_menu Action The jsp page for the result of ActionA calls get_menu to generate the menus. So suppose that ActionA sets a variable groups and get_menu also uses a groups variable... ActionA's variable will overtake get_menu's variable. I tried many solutions and even jsp:inculde doesnt help:(...

  • Autocompletion in Eclipse for Roo project

    - by niklassaers
    Hi guys, I've got a Roo project where I've made a couple of entities, and when I load up the project in Eclipse it loads up fine, but if I i.e. make an instance MyEntity entity and then write entity. I don't get any of my properties (i.e. getMyField) in the autocompletion list. If I write entity.getMyField() it compiles fine, that is taken care of by the aspects. How do I enable autocompletion for functions generated by the aspects? Cheers Nik

  • Create NinePatch at Runtime

    - by Pedro Lopes
    Hello everybody! I have a business need to create the NinePatchDrawable objects at runtime, this is, an exterior .png image is received from a server and it has to be applied in a button's background (for example) as a nine patch. I have tried to create the NinePatchDrawable object, but the constructor asks me for a "byte[] chuck" that describes the patch. The thing is, I have no idea on how to build this chunck from a bitmap that does not have the 9patch information in it. Any ideas on this topic? Am I seeing the problem from a wrong perpective? Thanks!

  • JSF hiding exceptions?

    - by bshacklett
    I have a managed bean for a JSF page which is doing JPA calls in the constructor to populate fields in the bean. I'm having a bit of trouble with another call to persist an entity (to populate data for testing). I'm expecting it to throw some sort of exception since it's not working, but I'm not getting anything. Just of the heck of it I tried the following: Query newQuery = em.createQuery("Bad Syntax"); List newList = newQuery.getResultList(); I'd expect an IllegalArgumentException here since the query string is completely invalid, but the page still loads and I don't see any exceptions anywhere. Am I right in expecting this exception? If so, why am I not seeing it?

  • ListAdapters and WrapperListAdapter algorithm

    - by Matty F
    This logic is written in a function with signature private void showDialog(final AdapterView<? extends Adapter> parent, String title, String message, final Tag subject) Is there a better way of doing this? // refresh adapter SimpleCursorAdapter adapter; if (parent.getAdapter() instanceof WrapperListAdapter) { adapter = (SimpleCursorAdapter) ((WrapperListAdapter) parent.getAdapter()).getWrappedAdapter(); } else { adapter = (SimpleCursorAdapter) parent.getAdapter(); } adapter.getCursor().requery(); adapter.notifyDataSetChanged(); Also, is there any point in having AdapterView<? extends Adapter> in the signature and not just AdapterView<?>?

  • how to register a selectionProvider for the Viewer from a superclass

    - by Tom
    I have a View which extends a View provided by another plugin like this; public class View2 extends some.other.package.View1 { public void createPartControl(Composite parent) { super.createPartControl(parent); //I want to do this, but I can't because its private //getSite().setSelectionProvider(treeViewer); } } But I can't edit the super class, so I need to access the viewer from the Control. public class some.other.package.View1 extends ViewPart { private TreeViewer treeViewer; public void createPartControl(Composite parent) { treeViewer = new TreeViewer(parent, SWT.V_SCROLL); } } I tried using parent.getChildren(); to get a Tree object, but I can't see that it can be cooerced into an ISElectionProvider as required

  • JSF/Seam - call one component method for many radio groups

    - by purecharger
    I've got the following jsf page: <h:form> <ui:repeat value="#{list.categories}" var="cat"> <h:selectOneRadio id="sel1Rad" value="#{list.choose}" layout="pageDirection"> <f:selectItems value="#{list.names}"/> </h:selectOneRadio> </ui:repeat> <h:commandButton id="submit" action="#{list.submit}" value="Submit"/> </h:form> And a component named list. The variable cat is injected to the component, used by the method list.getNames(). What I am trying to have happen is to have list.choose() be called for each radio group. I'm not sure if this is possible with Seam. Going by the booking example distributed with Seam, there is a distinct separate method for each selectOneRadio or selectOneMenu group. Since I have an unknown number of categories, I can't / don't want to define a method for each possible choice. When I submit the form, all my choices are sent in the POST, I just don't know the correct way to tell Seam how to dispatch them to my component. Any help is appreciated!

  • Killing Mysql prcoesses staying in sleep command.

    - by Shino88
    Hey I am connecting a MYSQL database through hibernate and i seem to have processes that are not being killed after they are finished in the session. I have called flush and close on each session but when i check the server the last processes are still there with a sleep command. This is a new problem which i am having and was not the case yesterday. Is there any way i can ensure the killng of theses processes when i am done with a session. Below is an example of one of my classes. public JSONObject check() { //creates a new session needed to add elements to a database Session session = null; //holds the result of the check in the database JSONObject check = new JSONObject(); try{ //creates a new session needed to add elements to a database SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory(); session = sessionFactory.openSession(); if (justusername){ //query created to select a username from user table String hquery = "Select username from User user Where username = ? "; //query created Query query = session.createQuery(hquery); //sets the username of the query the values JSONObject contents query.setString(0, username); // executes query and adds username string variable String user = (String) query.uniqueResult(); //checks to see if result is found (null if not found) if (user == null) { //adds false to Jobject if not found check.put("indatabase", "false"); } else { check.put("indatabase", "true"); } //adds check to Jobject to say just to check username check.put("justusername", true); } else { //query created to select a username and password from user table String hquery = "Select username from User user Where username = :user and password = :pass "; Query query = session.createQuery(hquery); query.setString("user", username); query.setString("pass", password); String user = (String) query.uniqueResult(); if(user ==null) { check.put("indatabase", false); } else { check.put("indatabase", true); } check.put("justusername", false); } }catch(Exception e){ System.out.println(e.getMessage()); //logg.log(Level.WARNING, " Exception", e.getMessage()); }finally{ // Actual contact insertion will happen at this step session.flush(); session.close(); } //returns Jobject return check; }

  • Eager loading OneToMany in Hibernate with JPA2

    - by pihentagy
    I have a simple @OneToMany between Person and Pet entities: @OneToMany(mappedBy="owner", cascade=CascadeType.ALL, fetch=FetchType.EAGER) public Set<Pet> getPets() { return pets; } I would like to load all Persons with associated Pets. So I came up with this (inside a test class): @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration public class AppTest { @Test @Rollback(false) @Transactional(readOnly = false) public void testApp() { CriteriaBuilder qb = em.getCriteriaBuilder(); CriteriaQuery<Person> c = qb.createQuery(Person.class); Root<Person> p1 = c.from(Person.class); SetJoin<Person, Pet> join = p1.join(Person_.pets); TypedQuery<Person> q = em.createQuery(c); List<Person> persons = q.getResultList(); for (Person p : persons) { System.out.println(p.getName()); for (Pet pet : p.getPets()) { System.out.println("\t" + pet.getNick()); } } However, turning the SQL logging on shows, that it executes 3 queries (having 2 Persons in the DB). Hibernate: select person0_.id as id0_, person0_.name as name0_, person0_.sex as sex0_ from Person person0_ inner join Pet pets1_ on person0_.id=pets1_.owner_id Hibernate: select pets0_.owner_id as owner3_0_1_, pets0_.id as id1_, pets0_.id as id1_0_, pets0_.nick as nick1_0_, pets0_.owner_id as owner3_1_0_ from Pet pets0_ where pets0_.owner_id=? Hibernate: select pets0_.owner_id as owner3_0_1_, pets0_.id as id1_, pets0_.id as id1_0_, pets0_.nick as nick1_0_, pets0_.owner_id as owner3_1_0_ from Pet pets0_ where pets0_.owner_id=? Any tips? Thanks Gergo

  • Constructor versus setter injection

    - by Chris
    Hi, I'm currently designing an API where I wish to allow configuration via a variety of methods. One method is via an XML configuration schema and another method is through an API that I wish to play nicely with Spring. My XML schema parsing code was previously hidden and therefore the only concern was for it to work but now I wish to build a public API and I'm quite concerned about best-practice. It seems that many favor javabean type PoJo's with default zero parameter constructors and then setter injection. The problem I am trying to tackle is that some setter methods implementations are dependent on other setter methods being called before them in sequence. I could write anal setters that will tolerate themselves being called in many orders but that will not solve the problem of a user forgetting to set the appropriate setter and therefore the bean being in an incomplete state. The only solution I can think of is to forget about the objects being 'beans' and enforce the required parameters via constructor injection. An example of this is in the default setting of the id of a component based on the id of the parent components. My Interface public interface IMyIdentityInterface { public String getId(); /* A null value should create a unique meaningful default */ public void setId(String id); public IMyIdentityInterface getParent(); public void setParent(IMyIdentityInterface parent); } Base Implementation of interface: public abstract class MyIdentityBaseClass implements IMyIdentityInterface { private String _id; private IMyIdentityInterface _parent; public MyIdentityBaseClass () {} @Override public String getId() { return _id; } /** * If the id is null, then use the id of the parent component * appended with a lower-cased simple name of the current impl * class along with a counter suffix to enforce uniqueness */ @Override public void setId(String id) { if (id == null) { IMyIdentityInterface parent = getParent(); if (parent == null) { // this may be the top level component or it may be that // the user called setId() before setParent(..) } else { _id = Helpers.makeIdFromParent(parent,getClass()); } } else { _id = id; } } @Override public IMyIdentityInterface getParent() { return _parent; } @Override public void setParent(IMyIdentityInterface parent) { _parent = parent; } } Every component in the framework will have a parent except for the top level component. Using the setter type of injection, then the setters will have different behavior based on the order of the calling of the setters. In this case, would you agree, that a constructor taking a reference to the parent is better and dropping the parent setter method from the interface entirely? Is it considered bad practice if I wish to be able to configure these components using an IoC container? Chris

  • Webwork actions, the lifecycle of variables declared in the action class.

    - by Sam
    Hi all, I'm using the webwork framework (JIRA plugin development) and was wondering about the lifecycle of the variables in the action class. I have a few private variables in the action class that are set when during the doDefault() method. These are used in the input view to set up jqGrid columns and then when the user has entered some data they click submit which puts the grid data into a hidden input. The next thing that happens is the doValidation() method is called before the doExecute(), which displays the input view if there are any errors. The problem is that the variables set up in the doDefault() method are now null. Can anyone explain to me how the lifecycle of variables works in the webwork actions? Cheers

  • How to identify the type of socket data?

    - by Nitesh Panchal
    Hello, May be i am not able to express my doubt properly in this question but still i will try. Basically i created a simple socket based chat program and everything works fine. But i think i have made many patches in it from the design point of view. I have used ObjectInputStream and ObjectOutputStreams in my program. The question i want to ask is how do i identify the different type of data that i send across the network? say if it is simple String type object i directly add to List<String> chatMessages. Now if want to ban certain users i created an another class :- public class User{ private String name; private String id; //getters and setters } This User class means no importance to me till now but i only created it to properly identify the action. Thus if i receive an instanceOf User i can be sure that some user is to be banned. That way i dont have to hardcode strings. I mean first i thought of sending something like "Banned User :" + userName and then i used to check if string startsWith "Banned User :" then i take some action :p. I've created a User class but it means no importance to me in my program. I want to know whether directly sending strings is good way or create a class for every action that is good. If i am not clear please let me know. If i have hundreds of action do i have to create hundreds of classes so i can check via instanceOf? Say now if i plan to create a BUZZ like facility that is available in yahoo messenger. Should i again create an another class named BUZZ? so it can be identified easily?

I tried once using 'scrollbar' too but the problem remains same. Suggest me something over this.

  • Webapp: safetly update a shared List/Map in the AppContext

    - by al nik
    I've Lists and Maps in my WebAppContext. Most of the time these are only read by multiple Threads but sometimes there's the need to update or add some data. I'm wondering what's the best way to do this without incurring in a ConcurrentModificationException. I think that using CopyOnWriteArrayList I can achieve what I want in terms of - I do not have to sync on every read operation- I can safety update the list while other threads are reading it. Is this the best solution? What about Maps?
