• How to get the controller class of the a fxml file open in a tab?

  Hello.
  First of all, sorry for my bad inglish, that is not my language.
  
  Introduction:
  I work in the skeleton of an enterprisse application in javafx. Generally (in the past), I used swing with InternalFrames MDI form. Search in the web site on how can he do this, I found that the concept of the MDI form is obsolete, is recommended to use a tabpanel structure. I started to develop the application with this concept, but I have a question.
  
  Scenario:
  I have a main window with:
  -Menu: To access the different options
  -Toolbar: To run the day-to-day operations (open, save, edit, delete and print)
  -TabPanel: To display the dashboard and fxml files opened from the menu.
  -Status bar: To display information.
  
  [http://www.blueboxmicrosystems.com/fxml.png |] See the image]
  
  The problem:
  I don't know how to access the methods of the controller of the fxml file on the active tab.
  
  Note: I have an interface with operations (open, save, edit, delete and print) and the tools of the interface controllers.
  
  The question:
  How can I me the controller class of the file fxml in the active tab in order to call methods?
  
  Kind regards

  Instead of

   Parent root =  FXMLLoader.load(getClass().getResource(fxmlFile));
  

  do

  FXMLLoader loader = new FXMLLoader(getClass().getResource(fxmlFile));
  Parent root = (Parent) loader.load();
  MyControllerType controller = loader.getController();
  // now you'll need to keep track of the controller somewhere, maybe a Map
  

  where of course you replace MyControllerType with classname of your controller.

  How to use paper in the latest version of Windows Live Mail?

  Version 2011

  Short answer: the stationery support has been removed from Windows Live Mail with the upgrade of v.2009 v.2011 back in 2010.

  Long answer: there are two solutions of workaround that you can try.

  • If you have a stationery .htm file, open it in Internet Explorer, and then select file > Send > Page by email (Alt - F E P). Save the message as a result as a .eml file and use it as a model for messages.
  • You can get in shape, for example a background color, to a HTML signature, then apply this signature to an e-mail message. Here's the one I use when sending pictures:

• JavaFX Tableview not link with the controller class (JDK 8)

  I have my 1.7 update javaFX applications java java 1.8. It seems now FXML TableView component will not be binding with reference to controller class Java. Thank you.

  FXML file:

  < fx:id = "dvTypeTbl" '49.0' = layoutX TableView on = '145.0' prefHeight = '388.0' prefWidth '800,0' = >

  < columns >

  "< TableColumn maxWidth ="5000.0"minWidth ="10.0"prefWidth ="420,0"text="%device.type.main.view.table.column.name ">

  < cellFactory >

  < com.stee.rcm.gui.fxml.FormattedTableCellFactory align = "LEFT" / >

  < / cellFactory >

  < cellValueFactory >

  < PropertyValueFactory property = "dtName" / >

  < / cellValueFactory >

  < / TableColumn >

  < / columns >

  < / TableView >

  Controller of Java class:

  / public class DeviceTypeMainController implements {bootable

  @FXML private static TableView < DeviceTypeTable > dvTypeTbl;

  @Override

  Public Sub initialize (URL url, rb ResourceBundle) {}

  With this reference now it will get null pointer

  DtList ObservableList < DeviceTypeTable > = dvTypeTbl.getItems ();

  }

  }

  It seems that static fields don't get injected into the JDK 8.

  I can't inject static fields has never officially supported. The documentation for @FXML and FXMLLoader are pretty awful, but no example in the official tutorial use static fields with the @FXML annotation. This seems to be a really bad design still: imagine later you decided to re-use the file FXML twice in your application: the second controller would replace the field injected by the first controller.

• How to use setFireActionForSubmit with the settings and capture the parameter

  Hello
  
  Can someone explain how to use setFireActionForSubmit.
  
  I extend the ShoppingCartPG controller. In the extended controller processRequest method I am adding a button to the table and implementation of the setFireActionForSubmit, so when the button is pressed it triggers the setFireActionForSubmit event.
  I need to pass the RequisitionLineId as a parameter which is present in the t associated with the ShoppingCartPG.
  
  I used the following code in the processRequest
  =================================
  ' public void processRequest (OAPageContext paramOAPageContext, OAWebBean paramOAWebBean)
  {
  super.processRequest (paramOAPageContext, paramOAWebBean);
  OATableBean otbRN = (OATableBean) paramOAWebBean.findIndexedChildRecursive ("ItemTableRN");
  OASB OASubmitButtonBean = (OASubmitButtonBean) paramOAPageContext.getWebBeanFactory () .createWebBean (paramOAPageContext, "BUTTON_SUBMIT");
  
  oasb.setID ("addnInfo");
  oasb.setUINodeName ("addnInfo");
  oasb.setText ("additional information");
  
  String pageName = paramOAPageContext.getRootRegionCode ();
  Hashtable params = new Hashtable (1);
  params.put ("param1", pageName);
  
  Hashtable paramsWithBinds = new Hashtable (1);
  paramsWithBinds.put ("param2", new OADataBoundValueFireActionURL (OASB, "${oa.encrypt.current.RequisitionLineId}"));
  oasb.setFireActionForSubmit ("addnInfoEvent", params, paramsWithBinds, false, false);
  
  otbRN.addIndexedChild (oasb);
  }
  =================================
  
  And I capture the event "addnInfoEvent" in processFormRequest method and trying to capture the RequisitionLineId I the past as a parameter.
  This is the code that I used in processFormRequest.
  =================================
  ' Public Sub processFormRequest (OAPageContext paramOAPageContext, OAWebBean paramOAWebBean)
  {
  super.processFormRequest (paramOAPageContext, paramOAWebBean);
  OAApplicationModule localOAApplicationModule = (paramOAWebBean) paramOAPageContext.getApplicationModule;
  
  String strEvent = paramOAPageContext.getParameter (EVENT_PARAM);
  
  If ("addnInfoEvent".equals (strEvent))
  {
  Number format = 0;
  try {}
  Format = new Integer (ClientUtil.getDecryptedParameter (paramOAPageContext, "param2"));
  }
  catch (System.Exception e) {e.printStackTrace () ;}
  
  String outmsg = "line ID:" + size + ":" + strEvent;
  throw new OAException (outmsg, OAException.INFORMATION);
  }
  }
  =================================
  
  But I'm not able to capture the RequisitionLineId I sent as a parameter.
  Can someone let me know what I am doing wrong.

  Hello

  Because your table is not a tip so table using a submit button approach will not work because it won't give you rank of reference and you will not be able to enter the id of the corresponding command line, instead you use an icon of the image, which can be created through customization. Let me know if you need help in the code.

  Thank you

• How to use and control the tabs?

  Sorry for such a general question, but I use Firefox with older versions of Mac OS x for years and have just been struck by this brand new and I have no idea on your tabs, "new tab page" etc. Can you just send me some documents so I can understand what they are and how to use them?

  All I see on my headers Ff are all sorts of legs that have no relevance to me, like 'how to stop Firefox from... '. "(twice), a few other symbols Ff and other"tabs"I don't know everything." All the do is filling up a bar line.

  Thank you-

  You are welcome.

• How to use notes during the writing of my book with pages?

  How are used to write a book with pages of notes?

  You need the Apple EndNote plug-in for Pages v2.0and the EndNote 7.3.4 application (or later version) installed for compatibility El Capitan. With the plug-in installed and EndNote works, then you start Pages v5.6.1 and the Insert menu: reference EndNote is available for use. Launch Pages v5.6.1 prior to 7.3.4 EndNote and endnote reference entry in the Insert menu is not active.

• How REGEXP_REPLACE used to replace the part of the string?

  Hello
  
  How can I replace the portion of string as follows, I want to replace the space as by ' - '.
  
  SELECT
  REGEXP_REPLACE (superior ("' Laura bought stuff from 2000 USD on 12 September 2012 to KL and kl left on September 20, 2012"),)
  ' [0-9] {1,2} [^ 0-9](JAN|) FEB | MAR | APR | JUN | JUL | AUG | MS | OCT | NOV | DEC) [^ 0-9] [0-9] {4}',
  (','-') "REGEXP_REPLACE.
  FROM DUAL;
  
  the output will be like this
  
  Laura bought of the stuff of 2000 USD on 12-Sep-2012 of KL and kl left on 20-Sep-2012
  
  concerning

  Something like that?

  SELECT
  REGEXP_REPLACE('Daivd bought stuff by 2000 USD on 12 Sep 2012 from KL and left kl on 20 Sep 2012',
  '([0-9]{1,2}) (JAN|FEB|MAR|APR|JUN|JUL|AUG|SEP|OCT|NOV|DEC) ([0-9]{4})',
  '\1-\2-\3',1,0,'i') "REGEXP_REPLACE"
  FROM DUAL;
  

  Explanation:

  You group the parts of the date de-construct with (additional).
  You can use expressions, backreference \1 \2 \3 and add '-' between \1-\2-\3 signs.

  You should not user upper ('...') in the first parameter. If you cannot recover the original state of the letters.
  If you want to case-insensitive matching you should use 'I' in the last parameter of regexp_replace.

• using methods of the builders class?

  I have a constructor that is quite complicated to ask my calling methods.
  I'm not sure whether to make these static methods.
  
  example #1
  class {Test}
  Object obj;
  
  Test() {}
  ....
  Initialize (this);
  ....
  }
  
  public static private Sub initialize (Test t) {}
  t.obj = new Object();
  doThis (t);
  doThat (t);
  }
  
  static private void doThis (t-Test) {...}
  static private void doThat (t-Test) {...}
  }
  -----
  example #2
  class {Test}
  Object obj;
  
  Test() {}
  ....
  Initialize();
  ....
  }
  
  private void initialize() {}
  obj = new Object();
  }
  
  private void doThis() {...}
  private void doThat() {...}
  }
  -----
  I understand the danger of use override-able for initialization methods, so take all the initialization methods are private.
  
  Directors of oriented programming OBJECT (as I understand them) suggest that instance methods are used to change the State of an object.
  Surely, the initialization changes the State of an object (forming / future).
  Yet, for some reason any when I call methods in constructors, I feel that these methods must be static.
  What is the right way of thinking?

  827723 wrote:

  Why?

  A static method belongs to the class and not any instance of this class. Make a method to initialize a static object is contrary to this principle. If you are already inside the class object / what possible benefit can you get pass a reference to itself between all your methods?

  Here is another alternative, a block to initialize.

  class Test {
      {
          obj = new Object();
      }
  
      Object obj;
  
      Test() {
          // obj already initialised, no need to do anything here
          // other code
      }

• How to get items of the skin class?

  Hi all

  I'm completely stacked to getting the items are defined directly in the skin class. To illustrate:

  I have a component of type SkinnableComponent having in turn, specific skinClass:

  MainApplication.mxml:

  " < = xmlns:fx s:Application ' http://ns.Adobe.com/MXML/2009 " ...   >

  < header: ApplicationHeader width = "100%" height = "30" / >

  < / s:Application >

  ApplicationHeader:

  < s:SkinnableComponent... skinClass = "components.header.ApplicationHeaderSkin" >

  < / s:SkinnableComponent >

  And the ApplicationHeaderSkin defines certain elements inside:

  < s:Skin... >

  ...

  < s:HGroup >

  < s:Label id = "label1" color = "white" / >

  < s:Button id = "button" width = "36" height = "100%" / >

  < / s:HGroup >

  < / s:Skin >

  The initial task is to instrument the skinnableComponent of ApplicationHeader to make it accessible for automation tools. For this I need to create a class of delegate with the method getAutomationChildren and getAutomationChildAt. The delegate is built with the obj SkinnableCompoment (ApplicationHeader in my case).

  So the question is: how to get children (or elements in the context of flex 4) defined in a class of skin only reference to the host of this skin component?

  I'd appreciate any hint, any reference to a description of the similar problem.

  Big thanks in advance

  Tim

  Referring to the hostComponent.contentGroup is the same as referring to the

  skin.contentGroup directly. The "contentGroup" is actually created by and there are

  in the skin, but it is accessible to the public through the hostComponent

  has declared a part of skin "contentGroup.
