  I added this Manager in verticalFieldManager.

  My problem is the two button touchevent last isn't getting captured.

  As Manager of footer I have headerManager (HorizontalFieldManager). That I placedonea the button on the left and right. In this event button to the left of the button you get captured but the right button touchevent is not getting do not capture.

  In short... the fields that I place in the right corner (1/4 of the screen) dod not capture the key event. It too is happeing in the camera.

  can someone please tell me what to do about it. I already posted my excerpt.

  Thank you.

  
  

• Cancel key event is not sent immediately

  It is a question for the gurus of management of key events. The problem I have is this: I have two containers A and B which are side by side and are equal in size and shape. If a finger touches the first A container, a touchdown event is generated on A. As your finger moves on a container, then touch MOVE events are generated. When the finger leaves container and begins to touch the container B, touch MOVE events are generated on B. When the finger is released during a B, CANCEL button is generated A and then b. touch UP

  Is it possible to receive on A CANCEL key as soon as the finger stops to touch a container?

  Thank you!

  On further investigation, I found a better solution that uses the onTouchEnter and the onTouchExit. As soon as the press finger leaves A container, onTouchExit is issued. As the finger enters container B onTouchEnter is issued. When the finger is released during a B, only editing event is released.

• Key events of injection, but couldn't find what corresponds to the BB button?

  I'm trying to inject a key event to simulate the user after pressing the Menu button - IE the one with the logo of BB, which is triggered by pressing Insert on the Simulator. I tried to use Keypad.KEY_APPLICATION (0x15), Keypad.KEY_MIDDLE (0 x 13), Keypad.KEY_MENU (0 x 1002) and there is no result to inject these keys at all. All the other keys I try to inject seems to work very well. There is another constant, should I use?

  Using the JDE 4.3.0.1r version and the 8120 Simulator, if that makes a difference.

  Nevermind, I got it works using a KeyCodeEvent instead of a KeyEvent...

• Key events on the fields in the custom horizontalfield Manager

  Hi all

  I created the screen with a title bar and toolbar.

  The toolbar is created with a HorizontalFieldManager.

  Toolbar contains three BitmapField and a LabelField.

  How can I manage the key events of the fields in the HorizontalFieldManager.

  Where I need to override the keyChar() method.

  I did something wrong here. I do not receive the dialog box by pressing the Enter key. It is moving to the next icon that's all.

  I can move each icon by using the arrow keys, it is also developed. But when I press the Enter key, it goes to the next icon.

  I want to show the new screen by pressing the Enter key on each icon in the HorizontalFieldManager.

  How can I solve this problem... Any help...

  Override KeyDown() in your screen. As:

      public boolean keyDown(int keycode, int time)
      {
          System.out.println("Enter key pressed!");
          if (icon1.isFocus())
              Dialog.inform("show page1");
          else if (icon2.isFocus())
              Dialog.inform("show page2");
          else
              Dialog.inform("show page3");
  
          return true;
      }

• Capture the event media export in Adobe Premiere

  We develop a html5 Adobe first Extension. The extension is important files to the editor of our archives. The files have two versions. HI-res and low resolution.  We import versions low-resolution to the editor. We want to change the path of the file of bass to high resolution when the user finishes his work and exports media (file-> export-> Media). Is there a way to capture the event of export and change the paths of the files?

  You can change the path using changeMediaPath() on project items.

  There is no way to capture the export event when the user is not interacting with your Panel. However, your panel could have a button "replace all the lower-res with high resolution.

  NOTE: If the dimensions of the image are different between lo-res and hi-res, your movies will look strange (images will be much too big, or too small). Use proxies with the same dimensions as the images high resolution.

• Key event to launch a video

  Hello!

  I started yesterday to use Adobe Flash Pro. I create a page with a video player and photos, each associated with a video that will play in the drive (sorry for the cacophony ). I was able to do this with a mouse event, by clicking on the event, but I couldn't do the same with the key event. I tried several combination, following suggestions from the program, but I have to face the fact that I have no instinct for extracts.

  Anyone know how I could program the code snippets for a touch of events associated with an image (the image of the tap) so that I can play a video in a vidPlayer in the same page?

  I apologize for my English, it sounds probably very funny...

  Thank you for the attention!

  Good bye

  You can use a mousedown event to detect a user tap action.

• No key event is generated from mac book pro trackpad

  I'm developing an application in javafx multiltouch on mac, but no key event was taken by the Manager using the trackpad. Event handlers are added to the scene.
  
  I use JDK1.7.0_07.
  
  Someone has an idea.
  
  Thank you.

  I don't think it will work. The javadocs for the TouchEvent explicitly state

  "Touch event indicates a touchscreen action."

  The trackpad isn't a touch screen.

  The trackpad will generate GestureEvents. Once again, since the javadocs:

  "Actions are usually caused by direct (touch screen) or indirect (track pad) touch events."

  If you can handle things like ScrollEvent, RotateEvent and ZoomEvent. I think that the mapping between the physical gestures on the trackpad and semantic events is managed by the operating system (if the behaviour could change if the user changes the settings for trackpad in system preferences, for example). It doesn't look like it will answer to your needs, but maybe...

  I don't know if there is another way to interact with the trackpad (someone else surely will).

  Here is a simple way to see which events are generated (it will generate a lot of output).

  import javafx.application.Application;
  import javafx.event.EventHandler;
  import javafx.scene.Scene;
  import javafx.scene.input.InputEvent;
  import javafx.scene.layout.AnchorPane;
  import javafx.stage.Stage;
  
  public class TouchTest extends Application {
  
    @Override
    public void start(Stage primaryStage) throws Exception {
      Scene scene = new Scene(new AnchorPane(), 400,400);
      scene.addEventHandler(InputEvent.ANY, new EventHandler() {
        @Override
        public void handle(InputEvent event) {
          System.out.println(event.getEventType().getName());
        }
      });
      primaryStage.setScene(scene);
      primaryStage.sizeToScene();
      primaryStage.show();
    }
  
    public static void main(String[] args) {
      launch(args);
    }
  
  }

• Capture the event of hyperlink and value

  Hi all
  
  I have a hyperlink on one column of the report, and when I click on the hyperlink, need me a URL. Now, I need to enter the time, the user has clicked on the URL and update a DB table column. So I created a dynamic event to update something, but I'm not able to get the hyperlink event. When I select the event 'Click' and 'Selection Type' as 'Élément', the report column does not appear on the LOV item (s). Can dynamic Actions be based only on the click on page elements?
  
  If so, are there any other to capture this event Hyperlink and set the value? Also, as my target 'Column link' is 'URL', I can't put any value for items it!

• capture an event in applications using an apps/db adapter

  Hello
  
  What is the best to capture an event in a db apps? I mean that is the best way to know that some data is inserted into a base table of apps? We have different ways like...
  (1) business event
  (2) write a trigger on the base table
  (3) the voting base table
  
  Mark is the best way or trigger? Some say that even if the polling stations and trigger on the base table are not the safest options, trigger is better than the poll than it consumes fewer resources database.
  
  I don't know if everything what I wrote above makes no sense. But I need the best way by which I can extract data from different tables in the basis of an instance of oracle using applications or the adapter database as and when the data is inserted in the
  
  Please suggest.
  
  Thank you
  RV

  As commercial is the preferred option, but they require a configuration a bit more, there is a note on metalink about this topic.

  The adapters of the poll is generally the second choice

  Last choice is triggers and should really be a last resort. It comes as part of the e-Business Suite, bespoke development it is accepted. It is generally not recommended to place a trigger on a table on delivered eBusiness. It is considered an envasive customization which means that you change the core component. You must only be who extend the functionality. Also, you can never be too sure what other hidden logic is behind the visible which can cause major problems.
