• Get the height and width of an image

  I have therefore some images in my program that I'm loading. These images are much longer than the size of the screen. So I put in a ScrollView. My question is how can I get the height and width of an image. The image.width and image.height doesn't return the correct values.

  //add the image
  private function addImage():Container {
      var sp1:Container = new Container();
      sp1.sizeUnit = SizeUnit.PIXELS;
      sp1.debugColor = 0xFFFFFF;
      sp1.margins = Vector.([1,0,0,0]);
      sp1.align =ContainerAlign.NEAR;
      //sp1.setSize(650, 800);
  
      var myPattern:RegExp = / /g;
      var fileName:String = "./com/swiz/img1.png";
      var icon:Image = new Image();
      icon.setImage(File.applicationDirectory.resolvePath(fileName).url);
      //icon.setPosition(0,0);
      //icon.setSize(320,800);
      sp1.addChild(icon);
      sp1.setSize(650, icon.height);
  
      return sp1;
  }
  

  and my code scrollview is

  //add to the scrollView
  var scroller:ScrollPane = new ScrollPane();
  scroller.width = 650;
  scroller.height = 505;
  scroller.y = 0;
  scroller.addScrollContent(addImage());
  addChild(scroller);
  

  Thanks in advance!

  Hey shethab,

  in order to retrieve the height and width of your image, you must use use the an event listener on your image and check for the Event.COMPLETE event. What is happening because the image you upload is not built, it takes time to load into your application using the setImage() method. and when you check the width height after the setImage method, the image was not loaded and has no height and width to this second. If you use the event listener, you can retrieve the height and width as it was finally loaded.

  Try the following code:

  import flash.events.Event;
  
  //add the image
  private function addImage():Container {
      var sp1:Container = new Container();
      sp1.sizeUnit = SizeUnit.PIXELS;
      sp1.debugColor = 0xFFFFFF;
      sp1.margins = Vector.([1,0,0,0]);
      sp1.align =ContainerAlign.NEAR;
      //sp1.setSize(650, 800);
  
      var myPattern:RegExp = / /g;
      var fileName:String = "./com/swiz/img1.png";
      var icon:Image = new Image();
      icon.setImage(File.applicationDirectory.resolvePath(fileName).url);
      icon.addEventListener(Event.COMPLETE, onImageLoaded);
      //icon.setPosition(0,0);
      //icon.setSize(320,800);
      sp1.addChild(icon);
      sp1.setSize(650, icon.height);
  
      return sp1;
  }
  
  private function onImageLoaded(e:Event):void
  {
      trace("image height: " + e.target.height + " image width: " + e.target.width);
  }
  

  hope that somethings brightened. Good luck!

• How to dynamically set the width of the bitmap as mobile size and adjust accordingly the photo.

  I have the bitmap image. Now, I want the bitmap to the screen but its size should be as mobile width and adjust the picture accordingly. For the former I enlarge it should look like small small mobile screen.

  My code but its not working.

  public static BitmapField getHeader() throws NullPointerException {}
  Bitmap b = Bitmap.getBitmapResource("img/logo.jpg");
  return (new BitmapField (b, Field.FIELD_HCENTER) {})
  Protected Sub layout (int width, int height) {}
  setExtent (365, 80);
  }
  });
  }

  You will need to put the image yourself to match the dimensions you need.

  Watch Bitmap.scaleInto)

• How to dynamically set the filter IR APEX of the value of a radio button column?

  Hello

  I built a simple APEX 4.2 IR report that includes column, namely "Source_Data" and a separate user to input radio button namly "P33_SOURCE_DATA" with two possible values in 'X' or 'Y '.

  I would like the report filter source_data = 'X' or source_data = "Y" is applied, after each time the user clicks on the radio button P33_SOURCE_DATA. "

  So my question is, how to set the value of the IR filter using the value of P33_SOURCE_DATA to the dynamic action and javascript?

  Thanks in advance.

  Concerning

  Susanna

  In this case, you can pull an onchange dynamic action on the radio, or at the click of a button.

  This dynamic action update your IR region

  And your IR region would have an appropriate where clause, with "Page to go" set on your radio.

• How to dynamically set the containers/component

  Hello

  I want to put on if containers of other condition.i.e condition if - set another container2 container1. How can I do? Any reference?

  Hey there,

  Because the way this all happens at the start of your application, simply use the add method that Simon bound for you in his first response.  Don't worry the method replace because that is only for all the containers that are already visible (or is already a child) within your root container (or whichever it is).

      // Just as an example from QSettings...
      if (mySettings.value("firstcontainer", 0) == 1) {
          myFirstContainer = Container::create()
              .layout(StackLayout::create())            .objectName("firstContainer")
              .vertical(VerticalAlignment::Center);
          // Add anything else for your first Container...
          // Then finally, you add it to your main or root
          // container with the add() function. Hopefully your
          // mainContainer is either a class member variable or
          // declared and initialized somewhere above this        // if-else statement.
          mainContainer->add(myFirstContainer);
      } else {
          mySecondContainer = Container::create()
              .layout(StackLayout::create())            .objectName("secondContainer")
              .vertical(VerticalAlignment::Center);
          // Add anything else for your second Container...
          mainContainer->add(mySecondContainer);
      }
  

  However, if somehow somewhere else in your application, you want to change the containers because the user has changed the value QSettings, you would replace it...

  if (user_wants_firstContainer) {    replaceC = mainContainer->findChild("secondContainer");    myCurrentContainer = myFirstContainer;} else {    replaceC = mainContainer->findChild("firstContainer");    myCurrentContainer = mySecondContainer;}
  
  if (replaceC) {
      replaceIndex = mainContainer->indexOf((Control*) replaceC);
  
      if (replaceIndex >= 0) {
          replaceC = (Container*) mainContainer->replace(replaceIndex, myCurrentContainer);
          // If you want to, you can just delete the replaced container here
          delete replaceC;
      }}

• How to outsource the JNDI name (dynamically set the JNDI name)

  Hello
  
  In the adapters such as ftp, database, must specify the jndi name. This binds the adapter to a particular jndi name. It's certainly better that connect the adapter directly to the physical resource, I was wondering if it is possible to have still more flexibililty-setting the jndi name dynamically.
  
  Basically my requirement is to develop a web service that reads a file from a FTP location. I know that I can outsource the file name and directory, but I wonder how to dynamically set the ftp location.

  Thank you

  OK, here is therefore the function for resizing of the model code. I tested several times with anchor points are offset on layers and centered, even with layers that are not yet within the limits of the Model Viewer. I'm sure there will be some users who eventually find something that will break it, but for now it seems to work perfectly.

  app.beginUndoGroup("CompResize");
    var myComp = app.project.activeItem;
    resizeComp(myComp, 500, 500);
  app.endUndoGroup();
  /* TESTING ABOVE */
  
  function resizeComp(compObj, newWidth, newHeight){
    if(typeof newWidth == "number" && typeof newHeight == "number"){
    if(compObj instanceof CompItem){

• show the height and width of the screen

  Is it possible to display the height and width of the screen in a labelfield?

  Yes. To do this, ask yourself two questions:

  (1) is it possible to display a string that I want in a LabelField? (The answer is Yes)

  (2) is it possible to set the height and width of the screen in a string? (The answer is Yes)

  (3) is it possible to find the height and width of the screen? (The answer is Yes)

  Now, just try to find how to do it ask these three questions. #1 is right there in the documentation for class, LabelField . #2 is trivial if all goes well. # 3, take a look in the view class.
