Changing the components of the user interface on a page programmatically

Do I need auto-bind backing bean if I have to programmatically change the attributes, the events of the user interface on a page components? I'm sure that Yes. Thus, each jsf page must have a bean of support to do the above and a bean managed to retrieve/store data? It seems that backing bean is more than enough. Why do I need a managed bean? Is there a way to delete unwanted ui components accessors in the bean to support? Thank you.

You need a support to programaticaly access bean and change elements on your page.
But you do not need to expose each component on your page in the bean support - the best practice is to expose a few components that actually access you.
So instead of using the auto-bind tge option that offers JDeveloper, create your page without a bean of support. Then when you need to access a specific object in your code, go to the attribute binding of this object in the property inspector, click the > change to his right and JDeveloper will give you a quick way to expose this specific component in a pod of support.

  • change the user interface presentation based on the size of the Panel

    I'm looking for a way to adjust the layout of my user interface based on the size of the group. For example, two buttons that are top of the other until the height of the window is small enough that they need to be next to each other instead.

    Another example would be a series of buttons that appear as a line if the Panel is wider than high, or in a column if it is higher than it is wide.

    -What someone does something like that, or know if it is possible? As I see it, all I need is a way to read the current size of the Committee and I can put a function in onResize/onResizing that allows to adjust the layout of the user interface.

    Figured it out!

    This change my row of buttons in a column of line based on the report of the window. Finally understood windowBounds.height and windowBounds.width.

    myPanel.onResizing = myPanel.onResize = function () {
      if (myPanel.windowBounds.height > myPanel.windowBounds.width){
           myPanel.grp.cmds.orientation = "column";
      } else {

  • Error variables look a tab after race change the user interface

    Hello

    I have a problem which seems to be a bit like this:

    http://forums.NI.com/T5/NI-TestStand/error-viewing-variables-tab-in-runtime-operator-interface/m-p/1...

    The VI I'm running is a step of edit of a type of step. LabVIEW checks if the property 'Step.Setup.ReadMeasName' exists, fills a listbox with her if she does. An another ListBox with all available measure names will also appear on the user interface. The user has an Add and Remove button to remove the 'ReadMeas' list box measures or add them to it of the listbox 'MeasNames '. Several names may be added/removed according to what is selected when you press the buttons. Once 'Fact' is clicked the VI writes the 'Ref' to the list box "ReadMeas" property to "Step.Setup.ReadMeasName", using a node to set the value of property that is passed the TestStand sequence context. If the property does not exist it creates.

    The only time where I have any problem is when I try to remove items from the property, after it is already initialized (i.e. non-empty). In other words, if I run the VI of teststand, put several names as in "ReadMeas" click on done, again run the VI (already added names appear in the box when the user interface is displayed, LabVIEW reads "Step.Setup.ReadMeasName"), then remove the names. IF "ThisContext.Step.Setup.ReadMeasNames" has opened in the tab 'Variables' step when you try to remove the names, I got this message in the Variables tab: 'one or more errors occurred. Please save your work and restart the application. "If I'm careful of not having expaded 'ThisContext' in the variables tab, but check the property before and after the removal of names in the list it does not work properly, and there is no error.

    This isn't a big problem because I doubt that the end user will check to see that the property has actually filled, but I still want to fix the bug if possible. I installed the patch for TestStand 2010 and the .net Framework 4.0. Someone has an idea of what might be happening here?

    Thank you

    Josh-

    Looks like you are running in a known issue 193751, which is documented in TestStand 2010 and 2010 SP1 known issues list. It is a problem that we intend to fix in a future version of TestStand.

    I hope this helps and I'm sorry for any inconvenience this issue may cause you.

  • How to change the user interface of the entity object indicators / Validation msg when running?

    Hello

    I use JDeveloper with version 11.1.1.6.3. Given my requirment details below.

    Suppose I have a (say 'EMPLOYEE_RATING') table in DB with the following structure.

    Columns:

    1 EmployeeId (Employee Id)

    2 RatingType (values can be in Stock or Bonus)

    3 RatingLevel (values can be 1, 2, and 3)

    Constraint:

    EmployeeId, RatingType and RatingLevel all together must be unique.

    Requirement:

    The customer's requirement is to have two screens of rating (one for Bonus another stock) and display different user interface boards and validations as follows.

    1 RatingType is a hidden field, are defined with the default (Bonus or Stock) based on the screen that the user opens.

    1. for the Stock screen, RatingLevel label should be "Stock note.

    2. for the Bonus screen, the label should be 'Bonus Rating'.

    3. for validation, the message must be 'Bonus note level must be unique' or 'Level of Stock of notes must be unique' ADB on the user screen opens.

    Implementation:

    I have a def EO (for example "RatingEO") and VO (for example ' RatingVO') def. Tips UI (Label) are given at the level of the OS. Also the unique constraint validation is made to EO with the message ' {0} and {1} must be unique, where {0} is source.hints.EmployeeId.label "and {1} is source.hints.RatingLevel.label.  I also did the shuttle two different instances of the VO (EmployeeRatingBonusVO and EmployeeRatingStockVO) in the request form (although BonusTaskFlow and StockTaskFlow are set to open with the new transaction, Intension of the two shuttle different named instances is to have the common code in VO. impl class but can run different business logic code by checking the name of the instance of VO)

    Question:

    Since I have two different pages, I can define two different labels in the jsff, but I can't change the commit message defined at the level of object entity based on open display. At the opening of the screen, depending on the type of screen, I should be able to change the label specified at the level of the entity object. (It should not affect the definition but only the instance). As this entity object cannot be distinguished (if it belongs to Bonus or Stock), I have problem on how to change the indicators of UI during execution.

    Any help on this would be appreciated! Thank you.

    Rami

    Post edited by: rami

    I tried your script.

    I created the secondary key with EmployId and rating level. I added validation of Unique key. In failure handling handling section of the validator, I gave the error message like: {0} must be unique. For token 0: I gave RatingType (here RatingType is the name of the attribute in OT).

    We give the default for RatingType as Stock Bonus in VO. kind RatingType get its value or Stock Bonus based on the original Version that we use.

    I hope this helps.

  • change the user interface fonts through the world

    I would like to change the font for my application, I have the method

              }
         }
    and it has worked well so far, but we must dynamically update (when the user presses a button or something) and the code above it changes only for components, so call at the beginning of the app is very well, but if you call it later so only new components have new police...

    I was wondering if there is any way to 'force' components to refresh their policies? Alternatively is there annother way to change all the fonts?

    Thank you

    It is one of the rare occasions when calling updateUI is the right thing to do :-)

    You can do with without changing the user interface. Something like:

    BasicComboPopup basic = (BasicComboPopup)comp;
    JList list = basic.getList();
    list.setBackground(...);
    
  • Is there a way to change the number of Sockets of Test, the User Interface of CVI?

    I would like to have the number of sockets in an INI file, the User Interface would be read the value of the file and set the number of Sockets of Test.  I know that it is possible by adding a callback sequence, ModelOptions, to my files in sequence and by changing the setting.  How would you do it in the UI?

    You might have the user interface to read and edit the reportoptions config file as the process template (see the source code for modelsupport2.dll in \Components\Models\TestStandModels). But why do you need UI to do this? Why not simply substitute the recall of ModelOptions and he do there?

  • How to change the size of the user interface component

    Hello

    How can I change the size (width and height) of the user interface component?  For example, I want to set the width of a ListField and add a scroll bar (horizontal). Thank you.

    Young

    GetPreferredWidth and getPreferredHeight methods can be rewritten to change the requested dimensions of a field.

    However, this does not mean that a field will support horizontal scrolling with only this change and can vary depending on the field.

  • How can I change the language of the user interface

    It seems that some efforts on l10n had been put in the latest TP. My host OS is Win 7 x 64 (Simp-Chinese) and I find that the user interface has been localized.

    As I have no option to change the language, could someone tell me how to do?

    BTW: I also noticed that some channels have not translated yet while some translations need to be improved.

    I wonder how can I report a l10n issues. As this community is English, I don't think I can report it here.

    Thank you.

    A solution from a member of the VMTN community. And it works:

    If you want to change the workstation to English user interface, you can open Control Panel, open "regional language and ' and change the format to"English (United States). Workstation displays in English.

    He also mentions that the l10n process is not yet complete. So I guess it would be better for people like me to inform after the final version.

  • Change the colors of the images between monitors while the user interface remains the same

    Hey! Im having a problem where photoshop change colors when I move the window between my monitors, see here: http://sta.sh/04y5s60vf3j is not due to the monitors themselves being different, it does actually change after a few seconds to move inbetween the monitors. The left was callibrated with an elite group of spyder 3 I do not have access to. I applied the file with windows instead of the utility of spyder color management. The second is new, and it is not callibrated by what that is, but instead was done by hand with integrated RGB brightness/contrast/custom settings. Two of them are very close to eachother, so enough for my taste. but when photoshop changes which looks like the image, it is causing problems. Curiously, when I disable calibration of the screen on the left, the image doesn't change color between monitors, but instead always appears as it does on the right. but then they do not match to the top and all the screen looked washed out because it's uncallibrated, so that won't do me any good. Something else interesting to report, is when this image is saved as a. JPG and read with firefox, the image appears exactly as the monitor on the LEFT (which is my primary monitor) despite the monitor left which is the force has changed. does anyone have any suggestions? It also appears that photoviewer windows behaves in the same way, although firefox does not work. Meaning when I open an image in all 3 on the left monitor, they look alike, but when opened on the right monitor, windows photo viewer and photoshop both display the image such as the brighter and redder that firefox works. It's frustrating, because it seems that photoshop changes the image with my measured on my monitor left to match what it looks like on the web, it does. but it does not for the monitor right, or the left is uncallibrated. Another question, I can see with this is even if the user interface is the same shade of gray, the images are different between the monitors because of this change. Does anyone have suggestions?

    -BD

    What you need to understand, is that Photoshop converts the image data, the document profile for the display profile, independently for each display. It is a managed pipeline standard color display. Windows Photo Viewer does the same thing (but do not have a lot of other applications).

    When you move a picture on the screens, it snaps when you drop; as the new display profile is picked up.

    Calibration is only partly about changing the monitor's response. The second part a profile, which is a complete description of the screen in its calibrated State. Then a conversion of standard profile is performed as he goes to the screen. The profile has a much higher level of accuracy than the single calibration.

    ---

    If the image on the web has the stripped document profile, Firefox with default settings does not have this conversion and sends just the unchanged data to display. In other words, it is not color managed. This behavior can be changed, but get your first straight base display profiles. Unless you get a new calibrator it is no that you can do to match these two views.

  • How can I change the language of the user interface for my trial version of Illustrator CS6?

    I don't know why, but I had the Danish, English or Dutch version would be nice.

    Re-download the package in the correct version. There is no way to change the language of the user interface on the trial in the case. Also check the settings of your system language. By default, installs broken will use the settings system locale. that cannot be replaced with a serial number when you purchase the product.
