Question Builder screen

Can I safely assume that all of the code in the constructor of the screen holds the lock of the event when it is placed on the stack?

I'm not sure that understand the second part of your question "when it is pushed on the stack.

The manufacturer is not necessarily related to the screen being pushed.  It is possible to have built but the screens.

If you want the screen to detect the moment where he was pushed first to display stack, you can substitute onDisplay().  If you want to know where it actually appears, you can override onExposed(), but remember that onExposed() is called on other occasions also.  However, I believe that these two work with the lock of the event.

Who help me?

    It's what warranties are for. If you bought the phone from Apple or an Apple authorized reseller, iPhone, you have 14 days to return it for a refund. After that the Bank should replace the phone. If you did not buy from Apple or a shop authorized, you must respect the terms of this store. However, Apple will always replace the phone, if you contact them directly.

  • Questions about screens

    Hi guys


    I have 2 questions about screens to OPA


    (1) how can I put a summary screen halfway through an application and view the status of the intermediate attribute and the values of the attributes at the basic level

    (2) if im dealing with several entities, how can I adapt the maintenance of the screen title to represent the selected entity.


    hope that makes sense

    Thank you

    (1) you can have the summary screen that appear as many times as you want, depending on how you chose to structure the objective attributes that you make available to the user on the summary screen. A simple example is instead of having a single objective attribute on the summary screen, divide the underlying rules in two attributes of purpose and have the second attribute hidden at the start of the interview. When the first goal is known, the user will return to the summary screen. You can use the visibility attributes to control the display of any intermediate or base attribute, you want the user to see and make your second goal visible so that the user can continue the rest of the interview. See the OPM help topic change how data summarized and reviewed interview for more details. According to the same approach, you can create far more sophistication in your summary screen design.

    (2) to have the title of the screen include the selected feature, use the substitution (for example % applicant ' s_name %). See the help topic OPM Change the text of an interview or of the sentence issue for more details.

    See you soon

  • Can cause of Google Chrome that any general Windows questions as screen freeze or startup problems? Thank you.

    Recently installed Google Chrome and started to add some PC problems. This could be a coincidence, but I was wondering if the Chrome can somehow interfere with the operation of Windows. Thank you for any light on the topic.

    Hi Anoop,

    Thanks for your reply. I checked the links you recommended, but did not find anything of note when I checked the logs events or performance. (I can't seek enough carefully.)

    Fortunately, the problem disappeared in the past few days and he can not Google Chrome to what has caused the occasional screen freezes. To answer your questions, Frost moved not just with Google Chrome, there is no error message and I have not recently updated the latest drivers.

    In any case, at the moment seems to agree, and if a conflict between Windows and the Chrome is not a good experience then it's probably just a coincidence that I met problems with my shortly after its installation.

    Once again, thank you for your help.

    Kevin.

  • Question view screen with custom fields

    I've developed a class that extends the scope and Implements DrawStyle. The field contains a bitmap with text drawn on the left of the it... nothing too complicated. I made focasable, has erased layout and drawFocus, painting, etc., but I'm having a Visual anomaly.

    On my screen (no title), I added a LabelField (non-active), and then a BitmapField (non-Focus), followed by a number of my custom fields. When the first screen, everything looks great. My first custom control has focus and is drawn as such.

    The problem occurs when I scroll through the custom control 3rd to 4th (causing the screen scroll), the 2nd custom control appears twice, the 3rd is missing and the 4th has the focus. There are also some white background that starts to show through (my controls are all black and is so the bottom of the screen and other controls).

    Of course, I'm having some trouble of painting, but it is certainly related to scrolling.

    What methods should be overritten in a custom control to ensure the scrolling will work properly?

    Which must be defined in the screen?

    1. prepare your screen unscrollable as:

    Super (NO_VERTICAL_SCROLL);

    2 use a VerticalFieldManager to add all of your components.

    Make sure verticalManager Scrollable and set its size and background color.

    Something like:

            mainManager = new VerticalFieldManager(Manager.VERTICAL_SCROLL | Manager.VERTICAL_SCROLLBAR)
            {
                //setting background color
                protected void paintBackground(Graphics graphics)
                {
                    graphics.setBackgroundColor(0x00000000);
                    graphics.clear();
                    super.paint(graphics);
                }
                //setting its height and width
                protected void sublayout( int maxWidth, int maxHeight )
                {
                    int width = Display.getWidth();
                    int height = Display.getHeight();
                    super.sublayout( width, height);
                    setExtent( width, height);
                }
            };
    

    3. now add this to your screen.

    Now your screen does not scroll and you will not get the white background at the end.

    Let me know if you have any questions.

    Hello and I would like to thank everyone for all of the information on this forum.  I have a question and need help for everyone.

    We do love the lenovo product and think the company is great and provides a service to us and our customers.

    My question is: I am ready to buy x201t for our Christmas stock.  We buy through distribution, not through lenovo, although directly that we have a rep of lenovo.  Us what distribution to purchase stocks and don't make any personal purchases.  I understand the 3 screens that are available...  I need to make that decision this weekend and need to know information about this model:

    Lenovo x201t 2985 AUS...  Is - this multitouch?  ...  I know that the term can be confusing... so basically whatever the term... with this model we can also use it with a finger, but the pen?  (mulitple input finger is not essential of our sales of Christmas but need to know if it can be used with a single finger at all?)

    Thank you in advance...

    Summary: Model x201t 2985 AUS...  It is STRICTLY only pen input?... or can finger input so... alone or both or NONE.

    Thanks again

  • R200 - Question about screen external resolution 1920 * 1200

    My boss bought this screen and is a little disappointed because he cannot reach the maximum resolution of the screen tft 23 "1920 * 1200. The R200 proposes that the resolution, which have an aspect ratio of 4:3, so the maximum for the screen is 1600 * 1200. Is there a driver 'special' for the graphics chip allowing non 4:3 resolution?

    Thank you

    Hello

    AFAIK on external display the maximum resolution is restriction of the graphics card and unfortunately there is nothing to do. The only thing you can do is check all the settings in the menu TFT. I'm pretty sure that you will find an option for switching of photo format.

  • Satellite M40x - 184 question on screen

    Hello I recently noticed that when I use normal mode or long-term my noteboook screen make a quiet noise
    and I want to ask you guys what is normal.

    Thank you very much

    Szczepaan

    Hi Tom

    It's normal, and you can hear it just enough ambient calm. I noticed the same thing on my Tecra. I'm not a technician but I think the supply voltage must be reduced by an electronic part and it produces that sound.

    If the brightness of the LCD screen is set to the maximum level the sound disappears.

  • Question about screen on Satellite P300 - 25 c

    Hello

    I was wondering if this laptop is like a mirror, or if it's a screen dark.
    Who can tell me?

    Thank you

    I guess under the mirror screen you mean TrueBrite screen.
    On almost all new laptops Toshiba screen is TrueBrite so I'm 100% sure that this laptop has this mirror screen.
    I checked the specifications specification and must tell you that this Satellite P300 - 25 c is great piece of hardware. Very good 1.3 MGPIX cam/mic built-in, powerful graphics. You can increase the RAM up to 8 GB. As far as I know you can also built in second drive HARD and his is fantastic with the harman/kardon speakers.

    A few months ago, my brother bought similar model but and it's great. If you buy it, believe me, you will love it.

  • You have my T430s Question on screen

    Hello

    I got my T430s for 10 days now and I am very happy with the machine, with the exception of the screen, which is manufactured by Samsung.

    When I have an all white screen, the bottom of it shows a white relatively well, while the top shows a grayish tone. However, when I have a picture with thin grey-white structures (for example the bottom of http://www.makeuseof.com/), these structures are clearly visible in half top of the screen and then fade down.

    Is this normal or should I get a replacement screen?

    Thanks in advance :))

  • Please if you have one coming 11 Pro, answer me this quick question - related /screen fans

    Are supposed to be two fans in the 11 venue? In particular the i3/i5 models?

    I noticed that I don't hear a fan, from the right wind, but on the other side is quiet.

    Also, when I have the screen displays something like XBMC or certain types of film, there is a light buzzing/grinding noise coming from the location of the vent on the left, as if he were a fan turning, but it is soft or broken. If there is no fan, so maybe it's just the sound of the screen running at high frequency - or maybe it's the wireless card?

    Thank you

    One fan and it's on the right side - where is the processor!

  • Question of screen Orientation

    I can't understand how to change how the screen orientation changes when I move my x 201 laptop mode to Tablet mode. As it is, when I close it for a Tablet, the screen becomes portrait, however I would like to change to make it reverse landscape (i.e. the computer mode unlike portable 180 degrees).

    I studied the topic online and I can't find answers, does anyone know how to do this?

    -chris

    There are 2 methods to configure (assumes that you are using Windows 7):

    1. Go to control panel > Lenovo Tablet utility > Auto Screen Rotation.
      (be sure to this Menu Popup Tablet is installed, http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-67219 )
    2. Go to control panel > Tablet PC settings > display (tab) > click on 'Go to Orientation', then you can see "Orientation sequence settings" there.
  • Question about Screen.getScreensForRectangle

    Hello Java Experts,

    Can you please explain what is the static method Screen.getScreensForRectangle ? According to the API description, I'm guessing that it applies to situations with multiple monitors are available.

    I'm only interested in working with a monitor at a time. So do you think I use the static method Screen.getPrimary () ?

    Thank you!
    Gregg

    Imagine that you have multiple monitors and the user positions the scene to a place where it extends from one monitor to the other (or more depending on the setting of the logical screen you). This method allows to detect a node is visible on which monitor (s).
