MakeMenu() call for a separate evil non-ecran class

Hello

I have the following classes:

public class QueueScreen extends MainScreen{}

public class GetQueue {

     QueueScreen screen;

     public GetQueue(QueueScreen screen){          this.screen = screen;     }}

The GetQueue class in the end updates the user interface of the QueueScreen by adding a new instance of the same ButtonField adding to the screen several times with screen.add ().  What I want to do, it's when one of these buttons has focus, add a special Menu with makeMenu() of the GetQueue class.

To repeat an example: with the class GetQueue, I add the same key for the QueueScreen several times (and identifies the button with setCookie()). Whenever one of these buttons is highlighted, I add a QueueScreen-specific menu item.

I tried adding a method of makeMenu() in QueueScreen and go to the getQueue method. It did not work, however. The only potential way I can think of is to use screen.addMenuItem () when ButtonField has focus and then removeMenuItem when ButtonField does not have focus. I couldn't get it work either, because each button is basically the same (only differing in its cookie).

What is the best way to achieve this? Thank you.

I could make it work. My mistake was that I tried to manipulate the focus() and unfocus() in my current buttonfield class. By substituting in the buttonfield class implementation has made the turn.

Thank you!

    When this error comes and what scenario?

    Thank you

    you don't know. You can find the details in the developer's guide.

    However a short explanation:
    all user interface work is performed in a separate thread, the thread of the event.
    If you do something in the user interface, for example in the display method, the instance is already on the thread of the event.
    If you do something outdoors, for example in a separate thread, you must place your changes on the thread of the event.
    only the thread the event is allowed to change the user interface.

  • View the calls for papers

    I'm content Chair EMP/BI for the Kscope16 Conference in Chicago. I would like to publish a call for contributions in the concerned areas.

    It of nothing that specifically prohibits this as far as I can see in the rules, FAQ or rules of conduct documents. The moderators have no problem with that? I don't really want to have my deleted messages simultaneously in eight areas and become a topic of conversation in the mod space...

    I do not think that a post from me on OTN involves any kind of support of the Oracle, but for what is interesting (and for those who don't know) Kscope is a 100% Oracle conference that enjoys the support of several "branches" of Oracle, OTN no less.

    I post here in order to achieve the OTN community managers (moniquevdb-Oracle, Laura Ramsey-Oracle and so on) for an 'official' answer and not to interview all the members, and very respectfully, I ask that someone don't not corresponding to the old description that wants to offer an opinion in a separate discussion. I'm sure that won't work.

    Thanks for your time.

    Product areas would not be the right place for this, but we can probably find a reasonable way to publish a call for contributions in a general area. I added you as a friend if you can me message directly. In the meantime I'll connect with Hocinebelatreche-Oracle and Oracle-valeriesimpson to make a recommendation.

  • Just got yet another call for "Windows Service Station"

    Just got yet another call for "Windows service station', saying: I was hacked and my computer sends windows warning messages and if I didn't follow his instructions all my data would be deleted... An Indian-sounding guy named Sam... I played along and got a phone number, saying: I would like to remind him he said 0808 1890111 which is a UK addiction hotline...

    I played along 'Sam' gave me an extremely long code to type in something on the windows event viewer... I know it's a scam and we have these calls often 3 times a week for a few years now. I play at the same time or am quite rude and tell them to be ashamed of themselves, depending on my mood... I really wish that they would go, but I can't this blocks 'any number' because it is off the coast.
    Any suggestions on how to remove our number and the name of their list (I asked the scammers do, but they don't notice).

    Certainly a SCAM, you have made the right choice. Never to give them information and never leave access to your PC.

    It is difficult, if not impossible to remove your number from a list of scam once its on it. And it's hard to know how they got it in the first place. It could be a list simple phone book. Recording with things like Telephone Preference Service (United Kingdom) and asking to be made "Red" (BT - UK) can make it harder for them to get a number in the first place, but once they have it probably wont help. It can stop any other do however.

    There are devices like Call Blocker, which can be programmed for their calls not ring your line, but it depends on what number they release when they call. If their number is "held" and then some providers have a service to stop calls "deductions number' to ring your line. ACR service (BT - Uk).

    PS - the links above are a few examples of our services/devices to the United Kingdom for more information.

    Newspapers showing your EP get no response from the return of unity to end a call is disconnected.

    This problem is the network problem, check firewall, router configuration.

  • received a call saying they were technical support from Microsoft, they called for my pc was hacked and sent error messages. I fell for this scam.

    I fell for what you all seem to feel is a "scam."

    I got a call saying they were technical support from Microsoft, they called for my pc was hacked and sent error messages. I was not too su re, but they had me enter a code on the pc, and it showed a list of more than 50 error messages, they said that they had received. Then, they control that is given to them for the mouse and seized a lot of information showing me the problems. Then he said warns me on; those pirates I needed a special program. "Alpha PC maintenance" and for 3 years, it would be $ 135. Now I don't know if it was the real scoop or I fell for a big pile of *! I could use the theory, I'm a senior, but I think I should have been smarter. What should I do now that they've been in the pc? Thank you JAFTX

    Or it is possible that the image is 16-bit/channel.

  • Why getter VO is not called for custom attributes of VO?

    Hello

    The requirement is to add two or three fields on a page of the OFA. Here's what I did:

    -Created VO personalized by extending the standard VO
    -Added fields to the page through customization.

    The problem is that the values for the custom page fields were not. Investigation, I found that the accessor Get of VORowImpl getAttrInvokeAccessor was not called for my custom attribute. I tried to check the difference between the attributes for which the Get accessor is called, and for whom it has not named. I could not find and I'm totally clueless as to what determines the get accessor to be called.

    Really appreciate your help to move forward.

    Thank you
    Anil

    Published by: AnilMenta on March 5, 2013 10:40

    Hi Anil,
    Unless the attribute is not used in the user interface or other calls,
    the Get accessor will be called
    Make sure you've got the attribute used to get your custom attribute named getter.

    You mentioned that you started to use in customization, it is always the problem persists?

    Thank you

    With respect,
    Kali.
