• Why not adding css class for table poster red border cell error?

  JavaFX 2.2.21 Java 7.21

  I'm trying to display a red border and a picture on a cell text when an error occurs.

  I took the address book example (example 12-11 http://docs.oracle.com/javafx/2/ui_controls/table-view.htm#CJAGAAEE).

  and also James D solution to my previous question.

  I find that adding a class of css error does not display the red border and the image.

  However, using setStyle this - but it is not preferable, because I want to put the border value by default once the error is corrected.

  In the example below, red border does NOT appear. The 'name' field was changed to salary and must display one error (red border and image) if other thing that an integer is entered.

  If you uncomment the setStyle lines, then it is displayed.

  Note: I use empty.png to erase the image of 'failure' because using - fx-background-image: none; somehow, did not.

  The css Setup is fine. The selector

  .a.b
  

  Selects elements that have the two class a and class b. Note that in this example, you set the style on the table cell class, not on the text field. So you have the selector

  .table-cell.error
  

  You can select the cells of a table with text fields that also have the style class 'mistake' set with

  .text-field.error, .table-cell.error
  

• Do not display properly accented characters

  Hi guys

  In my application, I received a .json file encoded in ANSI format, that contains characters such as aeiou. The interface has a ListView that loads the json data.

  In Beta 2, the texts were displayed correctly, but in Beta 3, the special characters are displayed as a box with an X on the device and Simulator.

  If I encode the file in UTF-8, nothing I've shown on the ListView, and it appears in the log:

  JSON ERROR: "* line 1, column 1 syntax error: value, object, or array expected.»

  The json file is loaded in C++ with this code:

  JDA BB::Data:JsonDataAccess;
  QMap jsonCont = jda.load("data/file.json").toMap ();
  Lst QVariantList = jsonCont.value("items").toList ();

  dataModel = new GroupDataModel (QStringList)<>
  dataModel-> setParent (this);
  dataModel-> insertList (lst);
  dataModel-> setGrouping (ItemGrouping::None);
  listView if (listView)-> setDataModel (dataModel);

  The texts are loaded in the ListItems with QML code:

  {Label
  text: ListItemData.title

  }

  I searched the forums and found this thread of special characters, but this does not solve my problem.

  I would really appreciate any ideas.

  José Ugalde

  Looks to his saying that your json file is misformatted, not if your accented characters are a problem.

• Why not save a file HOST Unicode or any other format beside ANSI format? Either way, which is Unicode format?

  Why not save a file HOST Unicode or any other format beside ANSI format? Either way, which is Unicode format?

  You would normally use unicode when you want to a text file that contains those outside of the normally the ASCII value... accentuated characters and others. They are rarely used in the definition of host names.

• Why not actually crop harvest?

  Let me explain. If I have an image with a certain number of objects, say a red disc and some rectangles. I want to integrate the Red disc in another new image. So I crop the image to reveal the drive and save the file as "Red Disk.psd". I open a new file, the blank page, the same resolution, perhaps we book (8.5 x 11, much bigger than the Red disc). If I switch back to red Disk.psd and use the move tool to drag a copy of the new file, I get the whole original image copied, drive & rectangles, even if they are not visible in red Disk.psd.

  If I use the selection tool to select the whole image red Disk.psd (or use another selection tool) and use CTRL + J to copy the background layer in layer 1 and drag just layer 1 to the new file, I get just the Red disc.

  So my question is if I've grown the original image and then saved the result as a new file, (in this case Disk.psd red), how this new file contains information of the original which exceeded the limits of culture? And how the red background in Disk.psd layer more include the information contained in the copy of layer 1?

  Thanks for the Enlightenment,

  David

  Hi David,

  It's because Photoshop is trying to preserve the non-destructive workflow. If you need to crop and remove the cropped area, you should check this option. After the harvest just to save your new file and do not save the original if you keep the original file or simply go back into history.

  I hope this can help. If this isn't the case, please let me know.

  Kind regards

• Why not set a number in this datagrid?

  Hello

  Flash CS5

  (Keep this separate from my other thread in order not to divert too much and help others with this problem.)

  I have a datagrid whose content is not pulled from an outside source, but written in the code just to test. The grid if you click above appears in a box of dynamic text on the stage, (after a section of youtube that used dynamic text) but I get:

  BusRoute: undefined

  Sttmnt1: Oxford

  Sttmnt2: Burford

  Sttmnt3: Swindon

  Why not the number?  It contains the number of this title for each line is said by the way.

  code is: -.

  Import fl.controls.DataGrid;
  import flash.events.Event;
  Import fl.controls.ScrollPolicy;

  var item1:Object = {BusRoute: '43', Sttmnt1: 'Oxford', Sttmnt2: 'Burford', Sttmnt3: 'Swindon'};
  var item2:Object = {BusRoute: "361", Sttmnt1: "Evesham", Sttmnt2: "ChippingNorton", Sttmnt3: "Am Buckingh"};

  var myTextFormat:TextFormat = new TextFormat();
  myTextFormat.font = "Arial";
  myTextFormat.color = 000000
  myTextFormat.size = 14;

  var datagrid:DataGrid = new DataGrid;
  DataGrid.Move (20.50);
  DataGrid.Width = 200;
  DataGrid.Height = 70;
  datagrid.rowHeight = 35;
  DataGrid.Columns is ["BusRoute", "Sttmnt1", "Sttmnt2", "Sttmnt3"];.
  DataGrid.Columns [0]. Width = 30;
  DataGrid.Columns [1]. Width = 70;
  DataGrid.Columns [2]. Width = 70;
  datagrid.resizableColumns = true;
  datagrid.horizontalScrollPolicy = ScrollPolicy.ON;
  datagrid.setRendererStyle ("textFormat", myTextFormat);
  datagrid.addItem (item1);
  datagrid.addItem (item2);

  addChild (datagrid);

  datagrid.addEventListener (Event.CHANGE, gridItemClick);

  function gridItemClick(event:Event):void {}
  
  DataGridSelectedRowText.text = "BusRoute:" + event.target.selectedItem.Task + "\n";
  DataGridSelectedRowText.appendText ("Sttmnt1:" + event.target.selectedItem.Sttmnt1 + "\n");
  DataGridSelectedRowText.appendText ("Sttmnt2:" + event.target.selectedItem.Sttmnt2 + "\n");
  DataGridSelectedRowText.appendText ("Sttmnt3:" + event.target.selectedItem.Sttmnt3 + "\n");
  
  }

  Envirographics

  
  

  In your objects item1 and item2 property you set first to be 'BusRoute.

  var item1:Object = {BusRoute: '43', Sttmnt1: 'Oxford', Sttmnt2: 'Burford', Sttmnt 3: "Swindon"};

  but in your attempt to acquire the data you seem to be referring to him as "stain".

  DataGridSelectedRowText.text = "BusRoute:" + event.target.selectedItem.Task + "\n";

  One of them must be changed to agree with each other.

• Characters do not... type characters!

  Hello

  I have Photoshop CS and when I try to use the text tool, it does not print on the characters but straight lines. So if I type A, it is reproduced on the screen as - and if I type B is reproduced as - and so on. I don't know why it happened.

  Any advice, please, on how I can see the characters?

  Thank you.

  Steve

  Try to reset your preferences, as described in the FAQ.

  http://forums.Adobe.com/thread/375776?TSTART=0

  You must physically delete (or rename) the preference files or, if you use the Alt, Ctrl, and shift, don't forget you get a confirmation dialog box.  This resets all settings in Photoshop default.

  A complete uninstall/reinstall will not affect preferences and a corrupted file may be the cause of the problem.

• Too much like Samsung: why not try it?

  Apple users don't want all our applications, notifications or 'ways to use the phone' or 'like samsung or android phones." Which will lead more people to their market. What happened to the innovative apple, which launched the iPhone? Nobody had seen a scrolling screen [when deflected] front. Nobody had seen apps or internet the iPhone in a way he did.

  Instead of looking to make things look more uniform like other telephone companies... Why not try to do something nobody has ever done before.

  Optical Lafarge, for example designed glasses that will put the glasses of google to shame. There is technology out there to make a phone clears the screen. You could still have the top and the bottom of the iPhone is the black bar where your battery would be in place etc. so that everyone can have the phone, they always wanted: phone The Tony Stark.

  

  It is quite easy for you to understand if he arrived at the place of the apple logo on the back of the phone or on the bottom or a chassis etc, but why not "two" batteries Wireless charging. a redesigned (as your macbook) to adapt the new clear phone (bottom) and the second to be located in the other "non-transparent" part as a solar powered battery to make it load when your phone is just sitting on its own... Obviously not as fast as being connected or wireless... but nevertheless he would become the first HYBRID phone that everyone has been waiting for.

  This is how I think that APPLE should do things. Being innovative doesn't mean "do what that other people do copy and then try to do better." That's what competition is supposed to do. When apple came out with new phones from iPhone to iPhone 4, they put the competition to shame. I remember a commercial Android who says more 'fast as the iPhone.' A week later, a new iPhone is released and put that commercial to shame so it never aired again.

  It's the Apple, we know and love. So if you want to be ahead of the market for any other mobile device, then you will make a clear phone out of the gorilla glass or hard extra stuff that is currently in your watches, so it is not breaking when you sneeze and you put wireless charge, a second solar battery, and siri will continue to improve as you work toward him making similar to an AI interactive as she understands us.

  So I guess the question really is: apple decides to take these technological leaps, or can I apply for a job at the company to throw these ideas around? (half joking about that second part.
