• Presentation of the card: 2nd card doesn't show text in the TextField

  I have a java swing application that implements the map layout and observer template. Basically, in the first map, I key in numbers in the button TextField and click on 'get number', it will run the Calculate class, which returns the number, which then informed his observer who is the Snd class. In the 2nd card (NDS class), it is supposed to set the number passed through the Observable (class Calculate) on the TextField. But my problem is that the textfield on the 2nd map does not appear any text. I already tried the getText method using the print method, and it returns the correct value for the observer last updated. It's just that TextField doesn't show anything. This is executable code.

• slide show by using the keys on the keyboard for nav in flash professional CS5 with animated images

  recently, I discovered how to create a slideshow using the keys on the keyboard for the market front and rear in flash professional CS5 thanks entirely to kglad of this forum. I used still images for each slide, since, then with one of the slides, I added a slight undulation of water in one of the images in a separate document. is it possible to include this file in my slideshow now?

  original questions and answers using still pictures below

  I'm a graphic designer who has a presentation of my portfolio. I'm not too experienced in flash and do not use it much, but he needs to do this on the thing. I can do a fade in and out slide show, but I want to create a slide show where the screen remains out of the blade and does ' t until what I press the next or previous button. I don't want these keys on the screen, I want to be able to press a key on the keyboard as F1. is this possible and do you know in adobe flash Professional (or other adobe products) where I could get resources/tutorials to do. Any help so what would never be great.

  response

  create tweens to fade for each slide.  You'll probably want to fade out the image on image 1 (from frames 1 to 11).  Bland-in the image of frame 11 frame 1 to 11.  fade the image frame 11 11 to 21 etc.

  You can then use:

  var image: int = 1;

  var dir:uint;

  stage.addEventListener (KeyboardEvent.KEY_DOWN, downF);

  function downF(e:KeyboardEvent):void {}

  {if(e.keycode==Keyboard.Left)}

  dir = Keyboard.LEFT

  Frame = Math.Max (Frame-10, 1);

  this.addEventListener (Event.ENTER_FRAME, nextF);

  } else {if(e.keyCode==Keyboard.RIGHT)

  dir = Keyboard.RIGHT;

  Frame = Math.min (this.totalFrames, Frame + 10);

  this.addEventListener (Event.ENTER_FRAME, nextF);

  }

  }

  function nextF(e:Event):void {}

  {if(dir==Keyboard.Left)}

  prevFrame();

  } else {}

  nextFrame();

  }

  {if(this.currentFrame==Frame)}

  this.removeEventListener (Event.ENTER_FRAME, nextF);

  }

  }

  you have the fla that created the swf file?

  If so, just copy images from this fla and paste into a new movieclip in your fla slideshow.  Add this movieclip to your timeline.

  the best way to do what you want (but not the most flexible/changeable) would be to add each slide a key frame to its own layer.  It is a design decision, but start with keyframes at 1, 11, 21 etc.

  create tweens to fade for each slide.  You'll probably want to fade out the image on image 1 (from frames 1 to 11).  Bland-in the image of frame 11 frame 1 to 11.  fade the image frame 11 11 to 21 etc.

• Satellite L500 - white screen. No attempt to start until the key.

  It is a Satellite L500, which was submitted to a process of recovery. The battery is as flat as possible and does not load.

  Turn on the laptop and the normal BIOS information is displayed with the option to press F2 or F12 at the bottom of the screen. The BIOS is configured to boot from the HARD drive first.

  Left to do his own thing, the screen turns off and nothing happens. A press any and there is no prompt text to touch anything, and the system begins to boot from the HARD drive. She proceeds to start successfully and the laptop runs normally (bar the old battery).

  I have reset the default BIOS and there is nothing, I see that it would otherwise cause.

  Any ideas?

  Hello

  Maybe it sounds silly now, but it is not easy to understand exactly what is happening.
  > Left to do his own thing, the screen turns off and nothing happens.
  All this occur after the installation of image recovery and first start after the installation of recovery successfully? Or pre-installed OS is already configured and ready for first start?
  >.. and the system begins to boot from the HARD drive
  You see nothing n the screen when this happens?
  > he proceeds to start successfully and the laptop runs normally (bar the old battery).
  After reading this sentence I presume boots OS OK and you can use your laptop. Can you confirm this?

  When you restart the operating system the same occurs again and again?

  Have you tried to reinstall the recovery still image?

• Why my video of p 720 and 1080 doesn't show 100% in the editing window?

  I just bought a new iMac and re downloaded the CC2015 Creative Suite. When you work in first my HD video displayed in the edit window, the value 100% does not appear to the right size to 100%. Display an HD picture in addition and opening it in Photoshop appears also not at 100%. The weird part is, when I released the video in HD formats, it plays well. I need a new dish somewhere. It didn't happen with the old iMac.

  YAE!

  OK, here's the deal. I was not a resolution setting that was what I suspected (new system). After thinking about what was different from what has crashed on me I ordered this new iMac with 4K retina display (anticipate working with 4K video in the not too distant future).

  The link below talking about a option in the app get the window information that allows you to open (what is now considered) low resolution when opening the apps that I've experienced this with. It's a checkbox in the apps get info window. Funny to think HD is now regarded as HD.

  Frequently asked questions on the use of a Retina - Apple Support screen

  In any case, this (see below) is what I was used to seeing, the display at 100% in the editing mode and a sequence of 1280 x 720, displayed 100%.

  Editing 1080 p video a following of 720 p.

  

  Same sequence set to 100%

  

  Same opening sequence edit window to display the entire sequence of 720 p.

  

  Thanks for your help Kevin. Like many things, discuss the matter sends the brain in altered directions and although not a direct shot, led to the resolution of the problem.

  I owe you a beer.

  All the best - return to work!

• IR is not for show results until the functions are applied

  I have an IR which produces about 400 000 information lines for two months to a data value. The user is not interested in all these lines. I would like to view the report after the filters (that is, functions such as filters, aggregates, etc.) have been selected. How can this be accomplished?
  
  Can someone direct me to the documentation on how to do this?

  http://apexcssjs.blogspot.com

  Hi, Robert.

  I saw your post and thought I might be able to help.

  Your question it seems that you want is to have your IR report appear without first recovering data. Instead, you want users to have a chance to choose the conditions of filtering and whatnot before actually running the report.

  I found the following link that deals with this feature in a very simple way.

• Cannot call ESC key two times of the key event

  Hello, this is my second post here...

  lately im trying to call the camera application via:

  UiApplication.getUiApplication () .addFileSystemJournalListener (new fileJournal());
  Invoke.invokeApplication (Invoke.APP_TYPE_CAMERA, new CameraArguments());

  and when the user to take a photo, then the application will grab the location of the file and close the camera application. but when I try to close the camera application using:

  Inject the EventInjector.KeyEvent = new EventInjector.KeyEvent (EventInjector.KeyEvent.KEY_DOWN, Characters.ESCAPE, 0);
  Inject.post ();

  Inject.post ();

  Simply call the inject.post () once and jump down (when I tried it on a simulator its works well but when I tried it on gemini 8520 is not working as the Simulator). I put the inject.post () at the end of my FileSystemJournalListener class.

  is there anyone who can help me please, thank you

  I had to use it to simulate the copy / paste before, it is what I did to get permission to use:

  ApplicationPermissionsManager apm = ApplicationPermissionsManager.getInstance();
  ApplicationPermissions ap = new ApplicationPermissions();

• Nature of the touch events

  Hello ladies and gentlemen,

  I am currently working on activating the touch support to an existing application to my friends, and I'm running into some difficulties. My screen consists of a few: on the bottom, I have a row of BitmapFields acting as buttons all content in a HFM, above that I have a great EditField, and above I have a HFM with a few more selectable BitmapFields.

  First of all, I'm not sure that should be implemented in touchEvent(), my managers or the fields themselves. I tried both, but noticed a strange behavior. It seems that the field that currently has the focus Gets the touchEvent little anywhere on the screen, the key event occurs.

  I think that the OS would simply understand that touching an object simply focusable means 'set the focus to this item"and clicking on the object means 'click on this object', I don't think you should even implement the touchEvent() method to achieve this effect.

  Does anyone have experience of writing applications for the storm? Am I missing something?

  Thank you
  Tyler

  Thank you Rex,

  I did a search on "touchEvent" but did not find much.

  Oops, looks like I just got this job.

  Let me explain what I have in case someone else comes on this thread:
  -My screen has a 'top manager' who handles most of the items on the screen, including other managers

  -J' have a HFM at the bottom of the screen (which is managed by my Senior Manager) that contains several BitmapFields that act like buttons
  -The question I had was trying to setFocus in the appropriate field when this field was hit

  Here's what I added to my managers to manage events:

  protected boolean touchEvent(TouchEvent event)    {        //Figure out where the touch occurred on the screen        int globX = event.getGlobalX(1);        int globY = event.getGlobalY(1);
  
          //Determine if the touch occurred within the extent of this manager        if (getExtent().contains(globX, globY))        {            if (event.getEvent() == TouchEvent.DOWN)            {                //Get the position of the touch within the manager                int x = event.getX(1);                int y = event.getY(1);
  
                  //See if there is a field at this screen position                int fieldIndex = getFieldAtLocation(x, y);
  
                  if ((fieldIndex >= 0) && (fieldIndex < getFieldCount()))                {                    //Set the focus to the field at this position                    Field f = getField(fieldIndex);                    f.setFocus();                }
  
                  //Return false so that the event propagates to the contained field                return false;            }        }
  
          //Event wasn't for us, handle in default manner        return super.touchEvent(event);    }
  

  In addition, you must ensure you set the scope of your managers correctly, both real as virtual, I usually do when I'm in the override of the sublayout() method.

  Hope this helps people.

  14. Click OK three times. If these steps do not resolve this issue, delete the Opa11.dat file or the Data.dat file in the following folder and then restart an Office 2003 program or an Office XP program:
      C:\Documents and Settings\All Users\Application Data\Microsoft\Office\Data

      If this does not work for you, I would take my installation CD< completely="" uninstall="" microsoft="" excel="" (or="" any="" other="" problems="" that="" are="" giving="" you="" this="" error),="" then="" install="" microsoft's="" windows="" installer="" cleanup="" utility="" (which="" completely="" removes="" all="" stuff="" pertaining="" to="" whichever="" program="" you="" delete,="" for="" you,="" excel)="" and="" then="" reinstall="" microsoft="" excel.="" this="" utility="" program="" is="" really="" powerful,="" and="" you="" can="" download="" your="" copy="" from="">http://support.microsoft.com/kb/290301.

      So, here are three options for you to try. I hope one works for you - let me know it to be.

• The keys Home and end no longer work when I enlarge the program window

  As I'm editing, I often use the 'home' and 'end' keys on my keyboard extended to the beginning of the sequence, that I'm editing, or to jump to the end (I use the "home" button more often, but I always use 'end' from time to time).

  This behavior works as I expect when I have the window of editing 'active' (by clicking on it). The behavior works even when the program window is active, which is very useful. (And because the source window has a different content, I'm not surprised that it interprets the keys start and end for this image, which is also useful also.)

  The problem for me arises when I want to watch my full screen in the sequence and use the key to accent grave ('), alias the tilda (~), in order to maximize the window of my program. Now my image fills the screen and I can watch my sequence down to maximum resolution. But when I get to the end and want to come back at the beginning, the 'home' key does not work. I have to shrink the window until the key will bring back me at the beginning of the sequence.

  This bothered me for so long that I was editing in first, but I have never taken the time to see if anyone has a solution to this problem. Does anyone know how to make this work because I expect to? If having a keyboard shortcut to the beginning of the sequence is useful when you work with a screen that shows all the windows, the keyboard shortcut would be even more useful when you do not see what you are doing?

  Is this a bug? Can I ask it as a feature in the next update? Any advice would be much appreciated.

  Thank you!

  Activate the program monitor before switching to fullscreen (~).

• filling of the notification "time" until the load went in 5.1 update

  has anyone (which improved lollipop 5.1) noticed that the notification load "time" until the load has disappeared.

  Indeed he disappeared, there is no way to bring him back, maybe if you use the old 5.0 locksceen
