• Scroll in the pane to scroll pane

  Hi all

  I'm trying to implement a user interface in which a horizontal ScrollPane behaves something like the iPhone (the one with all the app icons) home screen.  When a smear user right or left, the screen moves in the appropriate direction, snapping to the appropriate 'page'.

  This worked pretty well, but the first view must have a vertical ScrollPane inside.  If the user left or right moves the view has pass, but if the user slides up or down, the view remains the same - on the first page of scrolling pane scrolls right in the appropriate direction.  As soon as I added the second ScrollPane, everything stopped working.  Then, I made the internal ScrollPane has been to launch the ScrollEvent.SCROLL_BEGIN and ScrollEvent.SCROLL_END events, and now the part slam and scrolling, but very erratically.  I'm quite frustrated, I was wondering if someone could give me a hand here.

  Here's what I mean:

  var scroller:ScrollPane;
  var containerMain:Container;
  
  var containerHome:Container;
  var container2:Container;
  var container3:Container;
  
  function ContentSlider(){
  ...
  //configure containerMain, containerHome, container2, container3, etc.
  ...
  var v:ViewHome = new ViewHome();
  configureScroller(v);
  containerHome.addChild(v);  
  
  containerMain.addChild(containerHome);
  containerMain.addChild(container2);
  containerMain.addChild(container3);
  numPanes=3;
  
  //1024 * number of views
  containerMain.setSize(1024*3,600);
  
  scroller.setScrollContent(containerMain);
  addChild(scroller)
  }
  
          private function onScrollBegin(ev:ScrollEvent):void{
              originalScrollX=scroller.scrollX;
          }
  
          var i:int=0;
          var oldDelta:int=0;
          private function onScrollEnd(ev:ScrollEvent):void{
              trace(i.toString() + ": "+ev.currentTarget);
              i++;
              if(ev.currentTarget!=this.scroller)
                  return;
  
              var delta:int = originalScrollX - scroller.scrollX;
              if(oldDelta==delta)
                  return;
  
              oldDelta=delta;
  
              var scrollTo:int=0;
              var scrollTime:Number = 0.4;
  
              if(delta >1024)
                  delta=1024;
  
              if(delta<-1024)
                  delta=-1024;
  
              l2.text=delta.toString();
  
              //snap to previous view (to the left)
              if( delta > this.SCROLL_THRESHOLD ||
                  ( (0<(delta*-1)) && (delta*-1) this.SCROLL_THRESHOLD){
                  selectedIndex++;
                  if(selectedIndex>numPanes-1)
                      selectedIndex=numPanes-1;
              }
              scrollTo = selectedIndex*1024;
              trace("delta: " + delta);
              trace("scroll to: " + scrollTo.toString());
              trace("selected index: " + selectedIndex.toString());
              //meat and potatoes:
              Tweener.addTween(scroller,{scrollX:scrollTo,time:scrollTime,transition:"linear"});
          }
  

  And in the other class (ViewHome), I have a lot of Visual elements, one of them being the vertical ScrollPane.  Everything I have there are

  scrollerVertical.addEventListener(ScrollEvent.SCROLL_BEGIN,f);
              scrollerVertical.addEventListener(ScrollEvent.SCROLL_END,f);
              scrollerVertical.addEventListener(ScrollEvent.SCROLL_MOVE,f);
  
  private function f(ev:ScrollEvent):void{
              this.dispatchEvent(ev);
          }
  

  Hey cyangreen,

  Yes, I came across the same problem some time. I couldn't find a solution for this. When you have a scrollpane in a scroll pane, strange things begin to happen. I feel (from what I've read and seen) it's because the ScrollPane uses the position of the mouse in the scene. also the fact that the scrollpane receives apparently even mousedown events when there is an object on top of it he receives first. the only thing I can think is waiting until we have Swipe gestures available to use in the Simulator. hope that sheds some light. Good luck!

• Image in the scrolling pane does not appear correctly.

  Hello. I encountered this problem that my image and text inside my project is not correctly displayed after I added the scroll pane. The images and text were positioned on the left side of the project. It is supposed to be justified as usual. For some reason, continue to get my video clips alongside my scrollable area. So my image that had been displayed are displayed halfly. Someone knows how to fix this?

  It rests about alignment of the MovieClip, you will need to make at the top left:

  Double-click on the movieClip > select and combine everything (ctrl-A and ctrl-G) > use the window align tools, enable the option "Align on the stage" on the bottom, if it is disabled then (align the left edge and align top edge).

  EDIT

• Access to the scroll pane or TextArea scroll bars

  I'm trying to get messages to tell me when the scrollbar reaches the bottom of the text box.  I know that I can do this with vvalueProperty of ScrollPane, but I don't have access to one in the TextArea.  is it possible to get this or know when scrolling has stopped and I can check the location of the scroll?  I have tried the onScrollFinished TextAreas with any success.  Never, he triggered the event except when the papule mouse tried more than scrolling when he was already down.

  You can get the ScrollPane via a list of choices. I don't really like to recommend research, but sometimes, there seems to be no other way; and in this case the css structure is at least documented in the reference css.

  import javafx.application.Application;
  import javafx.beans.binding.Bindings;
  import javafx.scene.Scene;
  import javafx.scene.control.Label;
  import javafx.scene.control.ScrollPane;

  import javafx.scene.layout.BorderPane;
  import javafx.stage.Stage;
  
  public class TextAreaScrollTest extends Application {
  
   @Override
    public void start(Stage primaryStage) {
    final BorderPane root = new BorderPane();
    final TextArea textArea = new TextArea();
    final Label label = new Label();
    root.setTop(label);
    root.setCenter(textArea);
    primaryStage.setScene(new Scene(root, 400, 300));
    primaryStage.show();
  
    ScrollPane scrollPane = (ScrollPane) textArea.lookup(".scroll-pane");
    label.textProperty().bind(Bindings.format("Vertical scroll at %.3f", scrollPane.vvalueProperty()));
    }
  
    public static void main(String[] args) {
    launch(args);
    }
  }
  

  Be careful when you call textArea.lookup (...). The text box must have applied css styles so that it works. Typically, this means that he was tied to a scene which is displayed in a stadium. (If you move the search above call just before the call to primaryStage.show (), for example, you will get a nice NullPointerException.)

• TilePane within the scroll pane occupies only a small part of the screen

  I have a TilePane consisting of images, the images inside the tilepane is based on the number of images in the folder selected by the user. But there was no scrollpane in the tilepane component, so I decided to put the tilePane within a ScrollPane, but I'm not able to control the height of the scrolling pane to occupy the entire page.

  public ScrollPane viewGallery (steps)

  {

  ScrollPane root = null;

  final TilePane tile = new TilePane();

  try {}

  root = new ScrollPane();

  tile.setPadding (new INSET (5, 5, 5, 5));

  tile.setVgap (4);

  tile.setHgap (4);

  tile.setPrefHeight (stage.getHeight ());

  tile.setStyle ("background - fx - color: DAE6F3 ;"); ")

  File [] listOfFiles = outputFolder.listFiles ();

  System.out.println (outputFolder.listfiles (). Length);

  for (file: listOfFiles) {}

  System.out.println (file. GetPath());

  Image image = new Image ("file:"+file.getPath());

  Iv2 ImageView = new ImageView();

  IV2. SetImage (image);

  IV2.setFitWidth (250);

  IV2.setPreserveRatio (true);

  IV2.setSmooth (true);

  IV2.setcache (true);

  tile.getChildren () .add (iv2);

  }

  } catch (System.Exception e)

  {

  e.printStackTrace ();

  }

  root.setHbarPolicy (ScrollPane.ScrollBarPolicy.NEVER);    Horizontal scroll bar

  root.setVbarPolicy (ScrollPane.ScrollBarPolicy.AS_NEEDED);    Vertical scroll bar

  root.setFitToHeight (true);

  root.setFitToWidth (true);

  root.setContent (tile);

  Returns the root;

  }

  The output is something like this...

  http://i.stack.imgur.com/wpD1V.jpg

  But I want that it covers the entire page.

  I had the problem, did not know that borderPane behaved like that. I always used to think no matter where we are providing in borderPane that it must occupy the entire screen.

  As soon as I changed the piece of code below for

  border.setCenter (upperPart (internship));

  The problem has been resolved.

  MainWindow.java (where execution begins)

  @Override

  public void start (final stage)

  {

  try {}

  Use a component of border as root for the stage

  Border BorderPane = new BorderPane();

  border.setTop (upperPart (internship));

• SceneBuilder - how to anchor a TextArea in a scroll pane

  TextArea will not take on the size of the Scrollpane parent in Scenebuilder.

  Cannot find how to define it, no option anchor.

  This also applies to: HTMLEditor and the text box.

  TextArea comes with it's own scrollbars even when; It is not clear why you would need to put the text box in a scroll pane at all.

  In general, you can set the properties fitToHeight and fitToWidth on the ScrollPane; they will try to size height and width, respectively, of the content to the corresponding dimension of the scroll pane. You will find under "Available" when you select the ScrollPane.

• scroll pane cannot align its content

  When a node (Group for example) is added in a scrolling pane, the scroll pane automatically align the node to the left upper corner of the content area of the scroll pane. How can I customize the alignment of the node (Middle center for example) in the scroll pane. When the size of the node is scaling greater than the size of the pane to scroll bar scroll the scroll pane is displayed and if the node size is shrinking, and there the size becomes smaller that the scroll pane is then the node is aligned on the Community Center. It seems do not take effect if I replace layoutChildren method of the scroll pane and set layoutX and one property of the node.
  If anyone can give me some clue?
  Thank you

  ScrollPanes are a bit tricky to use. They line up not happy, you must use layout managers to do or you need to provision yourself with shapes in groups using absolute coordinates or translations. ScrollPane sets there own viewport associated coordinated and you need to provision your content in this window.

  How can I customize the alignment of the node (Middle center for example) in the scroll pane.

  The layoutBoundsInParent of the node, get the viewportBounds of scrollpane and perform the conversion of the node, such as the center of the node is at the center of the viewportBounds (requires a bit of simple math to do this) by adding listeners on each property.

  When the size of the node is scaling greater than the size of the pane to scroll bar scroll the scroll pane is displayed and if the node size is shrinking, and there the size becomes smaller that the scroll pane is then the node is aligned on the Community Center.

  Similar to above, come to work with these properties.

  Not exactly a direct answer to your question, but you can try to play with the code after if you like Saludon. This is something I wrote to learn about JavaFX layoutbounds system. Resizing of the scene and activating / deactivating elements on and outside will allow you to see the scroll pane. View limits listeners show you properties that you are interested in getting the desired effect.

• Action Script 2 with scroll pane

  The project I'm working on is only a Action Script 2.  Took a project IE updated to a site.

  What I'm trying to do is have a scrolling pane that will contain the images and linkable links

  So I have a:

  Scroll one component the instance name is spane

  I have a clip (with images done art card) and I have name myimage and the instance name is myimage

  The two are on a single layer and frame 1 (note there are more elements on the page but on different layers)

  I chose with instances (both) and action script I

  Spane.source = myimage;

  But it doesn't work at all, I've got is a box

  Any help would be great.

  The scroll pane will be working with action script 2?

  Thank you

  Is there an as2 scrollpane.

  You must use the scrollpane not the scrollpane as3, as2 and you use code as2 (check under components help files).  for example, use contentPath, no source for your as2 scrollpane component.

• Button to access within a scroll pane?

  I've set up a scroll pane component and the content of it is a layout of images that are buttons.

  Name of the scroll pane is "mc_pane2".

  Class content is "MyContent".

  And the instance name of the button is 'FloraLytell_btn' (it is essensially a mc with TweenLite code in it to roll over and spread the effects)

  I'm not able to determine what would be an access code to a button in the scroll pane. Here's what I've tried and it doesn't work.

  mc_pane2. MyContent.FloraLytell_btn.addEventListener (MouseEvent.CLICK, onClick_floralytellPopUp);

  function onClick_floralytellPopUp(event:MouseEvent): void {}

  gotoAndPlay ("floralyte2pp");

  }

  Try to launch the content as a MovieClip (the compiler refuses to accept that content is a DisplayObject without explicitly telling you)...

  TweenLite.to (MovieClip (mc_pane2.content). FloraLytell_btn, 1, {x: 200});

• The visible property works in content within a scroll pane?

  I have google searche and asked for a solution, but I can't mc._visible = false: or = true; work inside a scroll pane. I have several bubbles placed on a clip that is referenced by the scroll pane. I want the ToolTip to display the mouse on an affected area and disappear on mouse out. This code does not work:
  

  / * menu * /.
  sp.content.menuTxt._visible = false;

  
  sp.content.menux.onRollOver = function()
  {
  sp.content.menuTxt._visible = true;
  TPI Content.MenuX._alpha = 50;
  }

  sp.content.menux.onRollOut = function()
  {
  sp.content.menuTxt._visible = false;
  TPI Content.MenuX._alpha = 0;
  }
  

  But if I move the movie clip to the main stage and copy the code next works:

  
  / * menu * /.
  menuTxt._visible = false;

  
  sp.content.menux.onRollOver = function()
  {
  menuTxt._visible = true;
  TPI Content.MenuX._alpha = 50;
  }

  sp.content.menux.onRollOut = function()
  {
  menuTxt._visible = false;
  TPI Content.MenuX._alpha = 0;

  
  }
  There are some of the affected areas and ToolTips in the clip, and they are also video clips. Am I hitting against a limitation? I found a few references to the depth of clips with regard to scrolling but component which was confusing.

  The only reason why I don't see why the menuTxt would not work inside the scrollpane would be if he was missing his name of the instance.  I say this because to take your code and recreate what I can make the drawing or model and see it work in accordance with what the code told him to do.   It works according to the code, so if you see that it does not work by what you expected, it says not to do everything that it is.   Here is a link to the file...

• How to scroll by using the mouse wheel on a parent scroll pane

  Hi guys,.
  Imagine a table. In each cell of the table represents a component of a get. All aspects of ahmed are configured so that the scroll bar is visible only when it is necessary.
  Then, ALL cells contain scroll shutters, but only a few of them actually show a scroll bar.
  The entire table (which is very large) is also in a global scroll pane and is drop-down.
  
  My problem:
  I want to use the mouse wheel to scroll on the entire table. Because the table contains all its cells do scroll panes, the inner scrollpanes takes very quickly focus and global scrolling stops immediately.
  How can I force the weel mouse seize ONLY on the overall scroll pane? So basically not to transfer events to its internal components?
  
  I tried to disable the mouse wheel on all aspects of internal scroll:

  xxx.setWheelScrollingEnabled(false);

  ... but it doesn't.
  Any idea?

  So basically not to transfer events to its internal components?

  You must manually transfer the events to the external component to scroll.

  Using the concepts presented in [url http://tips4java.wordpress.com/2009/08/30/global-event-listeners/] Global event listeners, you can do something like:

  import java.awt.*;
  import java.awt.event.*;
  import javax.swing.*;

• A scroll pane is loaded dynamically?

  Hallo,

  I added a scroll pane or two via the Component Inspector to my site in flash.

  I know how to add content in the scrolling pane (rename contentpath to the new movie).

  My question: means that scrolling components loading dynamically, IE. they are called only for when you press a button to call this specific page that has the side scrolling and what it means it would save you filesize on your. SWF?

  Thank you!

  all components are related to the export for actionscript (unless cancel you that) which means that they download, whether or not they are used in a swf file.

• Help get the overthrow of the headphones to work in a scroll pane

  In AS2, how can I get a roll on listner in an MC inside a scrolling pane to display a ToolTip MC on the scene outside the scroll pane? I use the following code in the main time line to display the ToolTip, and it doesn't seem to work:

  //****Sel******//

  selectionTxt._visible = false;
  Sel.onRollOver = function()
  {
  selectionTxt._visible = true;
  }

  Sel.onRollOut = function()
  {
  selectionTxt._visible = false;
  }

  Any idea would be appreciated

  IF you load the library via its link ID, then the following may work...

  selectionTxt._visible = false;

  sp.content.Sel.onRollOver = function()
  {
  selectionTxt._visible = true;
  }

  sp.content.Sel.onRollOut = function()
  {
  selectionTxt._visible = false;
  }
