DefaultTreeCellEditor and component-class

The apidoc for DefaultTreeCellEditor says that a TextField will be used when no TreeCellEditor is suplied in the constructor. In the getTreeCellEditorComponent I tried casting the component to TextField with no luck. I need to do this because I need the text-value in the textfield, when editing is stopped, and that value isnt the same as the nodeObject, eg. when I stop editing nomatter what textvalue, it returns to the toString() returnvalue of my object. So I cant do a getLastPathComponent or similar because it returns my object and not the edited textvalue. Have I missunderstood that the getTreeCellEditorComponent isnt a TextField? And what class is it then? Ive tried casting to JTextField too.
Stig.

Got it: a JTextField inside a container.....
Talk about bad apidoc!?

    One workaround is to turn off automation:
    File-->Options, Advanced tab, General Section, uncheck "Enable Automation Events"
    However, you will loose the ability to configure callouts, and all of the commands in the Process Engineering tab.
    Another workaround is to change the loop number of the shape you are editing before changing its type. Then change the loop number back to the correct loop number.
    This is another example of the pernicious philosophy of trying to help the user do what the programmers think the user is trying to do that started in Excel 2000 (where you can no longer tell excel that you want a scatter plot - it will force the plot
    to be a line plot under certain circumstances).
    I suppose another option would be to modify the master and swap the text and subtype shapes in the indicator to use the subtype property for the loop number and then use the text for the instrument type. I guess this is what MS was trying to implement, but
    didn't explain it well enough to their programmers.

  • Why addcomponent and removecomponent method are not in component class,

    Hi,

    Thank you

    java.awt.Container has the appropriate add and remove methods:

  • Error  "expected a myfaces custom component class in package"

    Can anybody help me on this?
    just copied the sandbox code on selectmanypicklist and tried in a separate package of mine.
    created a jsp page and used the selectmanypicklist component and im getting the component on my browser.
    But whn i added the javascript resource calling by "encodeJavascript(facesContext, uiComponent);" im geting an error saying tht "expected a myfaces custom component class in package org.apache.myfaces.custom". i placed the java script file in "mypackage/list/resource/pikscript.js".
    should i add anything on faces-config.xml file or anywhr else?
    Anybody can help on this?
    Thanx in Advance.

    The problem is that it calls a method validateCustomComponent in MyFacesResourceHandler to see if it can load the js file. This method controlls if the path of the js file begins with org.apache.myfaces.custom. If not throws an exception and doesn't load the file. I changed the package of the class that's trying to load the file in org.apache.myfaces.custom.xx and the package of the file js in org.apache.myfaces.custom.xx.resource. Now it's working.

  • Unable to locate specified base class 'resources.style1.HelpButtonIcon' for component class

    Hi,
    I have a Flex (4.1.0) project, which has many skinnable custom components. The application allows a user to choose another style which changes these skins via loading a new compiled CSS. These non-default skins are in a separate Flex project.  I've not had a problem with this method until now.
    The custom component I am skinning contains several icons which are defined in the component like this:
    [SkinPart(required="true", type="mx.core.IVisualElement")]
    public var componentIconHelp:IFactory;
    then I use the iconRendererFunction to return the appropriate component part:
    private function iconRendererFunction(item:Object):IFactory
         //truncated method    
         return componentIconHelp;
    Within the skin for "style1", I then have
    <s:Skin xmlns:fx="http://ns.adobe.com/mxml/2009"
         xmlns:s="library://ns.adobe.com/flex/spark"
         xmlns:mx="library://ns.adobe.com/flex/mx"
         xmlns:style1="resources.style1.*">
    <!-- host component -->
    <fx:Metadata>
         [HostComponent("myApp.components.ButtonComponent")]
    </fx:Metadata>
    <fx:Declarations>
         <fx:Component id="componentIconHelp">
              <style1:HelpButtonIcon />
         </fx:Component>
    </Declarations>
    When I try to compile this, I get the "Unable to locate specified base class 'resources.style1.HelpButtonIcon' for component class 'resources.style1.ButtonComponentSkinInnerClass0'" error.
    If I remove the HelpButtonIcon from the <fx:Component> declaration, and just put it in the main body of the skin, it compiles and renders, but I need it to be a component (there's multiple components I have to choose from to display, similar to the ButtonBar skin).
    Any ideas why it's not compiling and what I need to do to achive this?
    Thanks

    Thanks, one step closer (or further away :-)
    I tried adding the airspark.swc to the library path for the project and it made no difference so I added:
    -external-library-path /Applications/Adobe Flash Builder 4/sdks/4.0.0/frameworks/libs/air/airspark.swc
    to the external tools configuration and now get the error:
    command line: Error: unable to open 'Flash'
    The project itself runs fine, it's only the ASDocs that's causing problems.

  • [svn] 4600: Flex SDK - Move style metadata from base class down to component classes

    Revision: 4600

    Log Message:
    Flex SDK - Move style metadata from base class down to component classes
    Previously, all spark and text styles were defined on FxComponent even though not every component supports all of those styles. So I have moved each style to the top-most base class where the style will apply to all descendant classes of that base class.
    This is the set of styles that were added to the various classes:
    baseColor
    color
    focusColor
    symbolColor
    selectionColor
    contentBackgroundColor
    rollOverColor
    alternatingItemColors
    basic text styles
    advanced text styles
    Here are some details about the implementation:
    - baseColor was added to FxComponent because every component and container supports it
    - FxContainer and GroupBase are containers, so their children can potentially support any of the styles. Thus the container classes support all of the styles indirectly.
    - FxDataContainer doesn't support all of the styles because its subclasses (FxButtonBar, FxList) don't support all styles.
    - FxList supports selectionColor, but not inactiveSelectionColor or unfocusedSelectionColor. All other components that support selectionColor, support the other two styles, and thus include styles/metadata/SelectionFormatTextStyles.as
    - GroupBase contains the style declarations that have the full ASDoc. All other declarations use the @copy keyword to reference the asdoc from GroupBase.
    QE Notes: Update tests to remove references to styles that are no longer allowed on various components/FxButton.as
    Doc Notes: Write the ASDoc comments for the style declarations in GroupBase

    Gordon, it looks like its been a while since you made this post.  Not sure how valid it is now...   I am particularly interested in the LigatureLevel.NONE value.  It seems that it is no longer supported.
    How do I turn of ligatures in the font rendering?
    My flex project involves trying to match the font rendering of Apache's Batik rendering of SVG and ligatures have been turned off in that codebase.  Is there any way (even roundabout) to turn ligatures off in flash?

    Thanks

    That sounds more like a NetBeans-specific question, not a general java programming question.
    Plus, your desciption is inconsistent:
    Cannot load component class <ProjectName>.Label from project: D:\Progetti\<ProjectName>.
    Cannot load component class ortholab2.Label from project: D:\Progetti\<ProjectName>What is the fully-qualified name of this class: ortholab2.Label ? ortholab2 being both the package name and the project name?
    And where do you use it, in the same project or in yet another NetBeans project?

  • The Component class

    Can anybody tell me why the Component class should be an abstract class? It seems to me that the class should be defined as a concrete class because non of its methods is abstract type. Thanks. altech

    Most likely it was done so that developers seeking to create a new flavor of AWT Component would be required to extend the Component class, rather than creating generic Components left and right. A generic Component object isn't really useful at all anyway, due to its lack of interesting behavior.
    The class is intended to act as an interface for users of Component subclasses (not interface as in a Java interface, but in the general OO sense of the word). It is a common root for all AWT "components," so that they may be acted upon in a similar fashion utilizing polymorphism.
    There may be a more legitimate reason why it is abstract, but this is my guess. It makes sense to me.

  • Difference and usage of Bapiname_Input and Bapiname_Output class from RFC

    Hi,
    When we create a model from RFC adaptive model we will get 2 classes for every RFC as Bapiname_Input and Bapiname_Output. What is the difference between these two. Most of the time we only use Bapiname_Input class for calling rfc by setting the import parameters from webdynpro.when we apply template on component controller and model, it always creates a function
    executeBapiname_Input() which does the calling of the rfc using model.execute.So what are the difference between Bapiname_input and Bapiname_output classes and in which case which is used.
    Thanks.

    Hi,
    BAPI_Input : has all the input parameters to the BAPI and also the table parameters.
    BAPI_Output : has all the output parameters from the BAPI and also the table parameters. Table is a two way communication, so it is available both in Input and Output Nodes.
    Usually we use BAPI_Input because all the import and table parameters are available in this node.
    But, when we have to use the export parameters (like the error flags, message text etc) you will have to use the BAPI_Output.
    Hope this helps.

  • Difference between custom controller and component controller

    Hi All,
    I am a beginner in CRM SAP .
    Please can anyone tell me whats the difference between custom controller and component controller with some scenario.
    I am totally baffled.
    Thanks in advance.
    Regards
    Shilpi

    Hi Shilpi,
    The main difference between custom and component controller is the role which they play during data transfer.
    a) Custom controller is used for data transfer across two views within a component. For that you need to bind view context nodes to custom controller either through wizard or manually by adding the code in CTXT class create_contextnode method:
    initial setting for depandant model node
        coll_wrapper =
          BTADMINH->get_collection_wrapper( ).
        TRY.
            entity ?= coll_wrapper->get_current( ).
          CATCH cx_sy_move_cast_error.
        ENDTRY.
        IF entity IS BOUND.
          BTOpportH->on_new_focus(
                       focus_bo = entity ).
        ENDIF.
    b)Component controller is used for data transfer across two views in two different components. For this, we need to define the component usage first and then bind the context nodes in the method-WD_USAGE_INITIALIZE of the Component Controller impl class.
        WHEN 'ComponentUsageName'.
          iv_usage->bind_context_node(
                      iv_controller_type  = cl_bsp_wd_controller=>co_type_custom
                      iv_target_node_name = 'ContextNodeName'  "#EC NOTEXT
                      iv_node_2_bind      = 'ContextNodeName' ).  "#EC NOTEXT
    Hope this clears some of your doubts!
    Thanks and Regards,
    Rohit
    P.S-This is valid for CRM 2007.Raghu is also right because Interaction Center is made up of different different components combined together.You have put your question in wrong forum.

    Simplified how an accessibility class gets hooked into its corresponding component class.
    We now do the hooking in the static method enableAccessibility(), which is called by code that is autogenerated by the compiler. Previously this method did nothing and the hooking happened at static initialization time. This allows us to remove the static var accessibilityHooked and the static method hookAccessibility() in each accessibility class.

  • Using Timer and TimerTask classes in EJB's(J2EE)

    Does J2EE allow us to use Timer and TimerTask classes from java.util package in SessionBean EJB's ( Statless or Statefull )?.
    If J2EE does allow, I am not sure how things work in practical, Lets take simple example where a stateless SessionBean creates a Timer class
    and schedules a task to be executed after 5 hours and returns. Assuming
    GC kicks in many times in 5 hours, I wonder if the Timer object created by survives the GC run's so that it can execute the scheduled tasks.
    My gut feeling says that the Timer Object will not survive.. Just
    want to confirm that.
    I will be interested to know If there are any techiniques that can make
    the usage of Timer and TimeTask classes in EJB's possible as well as reliable with minmum impact on over all performance.

    Have a look at J2EE 1.4. I think they add a timer service for EJBs there...

  • What is the difference between component(Y, Pb, Pr) and component(R,G,B)?

    [I previously posted this question in another thread as hadn't realised how to post new question]
    Q. What is the difference between component (Y, Pb, Pr) and component (R,G,B) ?
    I’d previously thought I was reasonably savvy on all things HD, but when I turned my thoughts to looking into getting a mac mini to run part of my home cinema I realise I have some confusions around the above.
    Here’s what I think I know:-
    The mac mini has a DVI output of the type which can output both digital and analogue, and so via physical adapters it could be used to connect to displays that take HDMI or VGA style RGB leads.
    I know on the market I can get a DVI to Component cable lead which would therefore lead me to assume it could drive my HD plasma with component input (Y,Pb,Pr), as I currently drive the HD TV via component cable with a SKY HD box (720p and 1080i), an xbox 360 (720p) and a progressive scan DVD player (480p), all through a Denon AV-amp.
    The problem is, I’ve heard somewhere that the DVI to component is R,G,B only and that it is not Y, Pb, Pr which is making me wonder it a) this will work and b) if I really understand component video afterall.
    I notice the Apple TV outputs Y,Pb,Pr but colours them red, green and blue, so am even more confused….
    Hopefully someone can help educate me on this !

    Thanks for this.
    My Plasma is a Panasonic 42" Viera March 2005 model. No HDMI, No VGA.
    It can process signals up to 720p and 1080i via the component (an interestingly it makes a huge difference over SD even though the native panel is 480..!?!)
    Am I right in thinking that the iPod component cable will also be R,G,B and therefor might be a suitable trial? Ie. if the TV accepts the input from the iPod then it should work for the mini?
    Only other thing of note is I'm doing all this via my Denon 1707 AV amp which does have the facility of upscaling, but I imagine it needs to stick to one format?
    Thanks.
