• Problem with fieldChanged() and custom button field

  Hello

  I created a custom button class by extending LabelField.  I chose LabelField over field because the LabelField contains desirable properties that are already being implemented.  The only problem I'm having has to do with the change listener.  It seems to 'steal' the event click on other areas in my application.

  For example, when I click on the custom button, a popupscreen with a listfield opens. When I click on an item in the listfield, then the fieldChanged() of custom button is called again...

  Can you see anything wrong with my code?

  Now, I'm not sure why customButton.setText (calling) would trigger the fieldChanged().  Can anyone think of a reason why he can do?

  Thank you!

  Can you think of a reason why we can't do that? The field has changed, after all! Of course, the context (second argument to fieldChanged) will be PROGRAMMATIC in this case, that might be a pretty good indication for you. But not invoke fieldChanged at all would be wrong.

  This is why I don't like the idea of extending LabelField and not just the field for your custom badges - you have much less control over his behavior. If you want an example showing how to create abstract off-screen buttons, take a look at BaseButtonField and his descendants in managers, fields and advanced buttons.

• border problem is not show on the right

  Hello

  I create two LabelField label1 and label2 and then I added the border both of them... and then I added

  thesefields to HorizontalFieldManager...

  Problem is that when I use the method of layout in LabelField (label1) and border on the right side of the LableField (label2) does not appear...

  LabelField label1 = new LabelField ("IMEI")
  {
  protected void paint (Graphics g)
  {
  g.setColor (Color.WHITE);
  Super.Paint (g);
  }
  protected void layout (int width, int height)
  {
  Super.Layout (width, height);
  setMargin (new XYEdges (0,0,0,50));
  }
  };
  Label1.setbackground (BackgroundFactory.createLinearGradientBackground (Color.Green, Color.Green, Color.Green, Color.Green));
  Label1.setBorder (BorderFactory.createBevelBorder (XYEdges (2,0,2,2))) of new;

  LabelField label2 = new LabelField ("dasd");

  Label2.setbackground (BackgroundFactory.createLinearGradientBackground (Color.Green, Color.Green, Color.Green, Color.Green));
  Label2.setBorder (BorderFactory.createBevelBorder (XYEdges (2,2,2,2))) of new;

  HFM HorizontalFieldManager = new HorizontalFieldManager();
        
  HFM. Add (Label1);
  HFM. Add (Label2);

  I don't know what the problem is, but you need to move this:

  setMargin (new XYEdges (0,0,0,50));

  out of the page layout.  The framework calls available when we want to know how much space to allocate to the device.  You have to set the margin before that date.

  So get out there and make a

  Label1.setMargin..)

  as you define the border.

  I see that your two BorderFactory calls are slightly different.  Is - it deliberate?

• MacBook Pro display problem

  Hello members of the community.

  As of recently, I have noticed some glitches when feeding on my MacBook or awakened from his sleep.

  The colors are distorted, usually with pink, green, or yellow blobs. Blobs cannot entirely replace the colors, they appear to be contained in a element would normally be. For example. the menu bar will be partially pink and white, but pink does not leave the menu bar in this area, and the Office has green lines on it.

  I tried to take a screenshot, but the problem resolves in about 20 seconds, but it's a recurring problem.

  It happens when I wake up, connection or not. I had also certain powers serious and problems of performance, such that my MagSafe LED would not illuminate when plugged on rare occasions, fan could turn unnecessarily, graphics performance were SUPER slow, and the health of my battery was running out quickly. I actually ran a report on the system at 2 different times and my quality of full load is depleting of 1.2% per charge cycle, which is very worrying. I went from 6281 mAh mAh 6138 maximum capacity after two cycles of load. I'm tracking closely it because at this rate, my battery will survive only at load cycles about 150 instead of the 1000 expected, gives me the idea that this could very well be a bad battery. The computer is also warm to the touch while you sleep, not connected to the power supply. I NAP active but even taking into account should not be hotter my iPhone did the same thing.

  I have reset the SMC, and it solved a couple of problems. The charger works fine now and my performance improved considerably (which made me feel better, either it is a high-performance laptop, a 11-inch MacBook Air should not he surpass), and battery life has improved. I feel even if it uses a lot of power in his sleep. Maybe I need to turn off the NAP and see if that makes a difference. The graphic bug still persists however, and I don't have enough time to see if the max battery is depleting again.

  In regards to the bug, is there something that can be done? Basically, I want to assure you that I took all appropriate measures or if someone else has this problem to see if it can be software related instead of my computer.

  I have the entry level MacBook Pro with the retina, last generation.

  Any constructive contribution welcome!

  See you soon.

• with IOS 10.0.2 - 5s iphone Bluetooth problems

  Since upgrading ISO 10.0.2 my M50 from PLT Plantronics (helmet unique headset) do not reliably connects with my iPhone 5 more. I have to go to the settings, activate bluetooth turned off/turned on, touch the device on the bluetooth page, etc. Once it connects successfully, it will reconnect (if I turn off the headset and turn it back on) for a short period. The next day he does not connect itself but I play with bluetooth on the iPhone again.

  It has always worked perfectly before the 10th of IOS.

  And, as I noticed others mentioning, the volume is much lower with IOS 10. The maximum volume is much lower. I can barely hear it now, more normal background noise, while driving.

  I did:

  Forget this device for the PLT M50 and paired again (several times)

  I did a Reset Network Settings

  I don't know what else to do - but it's a 10.0.2 IOS issue.

  Hello AppleUser2k,

  Please ask questions about your problems of connection between your iPhone and your Plantronics headset since you upgraded to iOS 10. I understand how important it is to have your Bluetooth devices connect with your iPhone with reliability. Here's what I recommend.

  Once your data is safe, try the troubleshooting steps in this article to help: get help to connect a Bluetooth accessory with your iPhone, iPad or iPod touch device should also check with the manufacturer that the device has all the drivers and firmware to work with the new version of iOS.

  If you have checked everything and that you have installed the latest firmware or driver and always are problems, please be aware of your surroundings when you encounter these problems. If you can isolate the time or location, you see the problems, you can isolate the cause. You can even see this help article to ensure that you are not affected by outside interference: the potential sources of Wi-Fi and Bluetooth.

• Problem activation ISO 10 September 2016

  After my Ipad iOS 10.0.2 update I could not activate because it says I am not access with the original Apple journal. Makes no sense. I bought the new Ipad in seven of 2013 Dabs.com. She has been linked to my Apple account 10 days ago (I deleted my profile by own Apple support Web site suggestion as a way to fix my problem, the other restoration/upgrade to the Ipad with ITunes update). I contacted the support of Apple (I have two numbers in case Apple). Asked Apple support to provide a proof of purchase I made. Told me now the reception that I provided does not correspond to my Ipad, but Apple isn't going to help with all the details to help to regularize the situation. The Ipad is mine and well was linked to my account from the date of purchase in September of 2013 until I removed it at the suggestion of site specific help from Apple. I now do not have access to my ipad £460 for more than 10 days and have lost money and time talking to 4 different cooperatives of Apple, after 6 calls and none seem able to deal with a ridiculous situation. Alexandre Vitorino (Apple) seems to have the best handle on weird how this situation is. Please can someone fix this? A software update on an Ipad that I own shouldn't stop me using it and then force me to prove that I admit actually before I use it again! I'm a professional businessman who uses it for meetings of the Council. I have a receipt for my camera and get treated like a kind of criminal.

  My sincere sympathy for those who can't find their original receipt or forget their original log-in Ipad because Apple does not help, you and your Ipad will be also useless mine is currently!

  Lock activation occurs when the ID of original Apple blocking it does not match with your current Apple ID.

  Until you can bring a receipt valid from an Apple reseller or authorized, it's nothing you can do.

  BTW, the polling stations in this Apple-owned forums is prohibited. You can review the terms of use.

• Anyone know how to solve my problem? I can't import my photos from Iphone to computer. Sign says: Photos in the camera cannot be imported because the IPhone is locked with a password or read. My phone is unlocked. I've tried everything

  Anyone know how to solve my problem? I can't import my photos from Iphone to computer. Sign says: Photos in the camera cannot be imported because the IPhone is locked with a password or read. My phone is unlocked. I tried everything, every single idea. Without success! Any other idea?

  For example, you specify that the device does not display the lock screen, correct? Do you use Touch IDS? If so, try to put your finger on the device to see if it's what he wants.

  See you soon,.

  How long it has been blocked? You have a very large library so I keep the Mac awake and fed and the Photos doesn't work does not and give him a few days - usually messing slows it rather than speeding it and is a 'restart Yvert"command
