Scroll pane and contentPath

I am trying to get a handle on the scroll pane. I got the
effect I want on a movie clipe, but when I tried to put everything
into a scroll pane, I got hung up. The problem seems to be in this
loop with the contentPath command.
for (var i = 1; i<=IconMap.length; i++) {
IconClip
= myScrollPane.contentPath.createEmptyMovieClip("btn"+i,
i+1000);
mcl.loadClip(IconMap, IconClip
//myScrollPane.contentPath.loadClip(IconMap, IconClip
ImageClip =
myScrollPane.contentPath.createEmptyMovieClip("bt2"+i, i);
mcl.loadClip(ImageMap
, ImageClip);
//myScrollPane.contentPath.loadClip(ImageMap
, ImageClip);
Is this going to work? am I missing something simple or do I
have to start all over again.
Someone please give me a hand.. I have been unsuccesfull at
getting any help at all here.
Thanks,
David

OK fair enough.. I know I tried that a million times, but it
seems to work!
now the content shows up, the scroll works just right, but
the content is scaled with the scroll pane.
if ((IconCount/2) == (Int(IconCount/2))) {
myScrollPane.content._yscale = (int(((IconCount / 2) * 158)
+ 30)) * 100 / myScrollPane.content._height;
} else {
myScrollPane.content._yscale = (int(((IconCount + 1 / 2) *
158) + 30)) * 100 / myScrollPane.content._height;
Is what I have but what I really wanted is
if ((IconCount/2) == (Int(IconCount/2))) {
IconMovie._height = (int(((IconCount / 2) * 158) + 30));
} else {
IconMovie._height = (int(((IconCount + 1 / 2) * 158) + 30));
The first works correctly with the scrolling, but messes with
the scale of the contents which I add after the fact. Any idea how
to make the second work? It seems to not change anything. The
content is correct, but the scroll bar is not functional now.
Thanks again!

Scroll Pane - Drag and Drop

Hello,
I have to scroll panes and movie clips in the one scroll
pane while the other is blank. I wanted the user to be able to drag
the movie clip out of the one scroll pane and drop it into the
blank one. Any ideas? I'm totally lost on this one.
Thank You

Hi Sarojamaly,
According to your description, when you create a Data Source View in BIDS/SSDT, you can't see the tables in the pane. Right?
In this scenario, when creating data source, please make sure you select a correct data provider. For example, it you connect to SQL Server database, you should use
Native OLE DB\SQL Server Native Client. Then please test your connection to the data source.
If the tables still can't be displayed, please make sure you select proper database and the check tables existence in the database.

Dynamic content in scroll pane component

As far as I can see, the contentPath for a scroll pane
component can only point to a movie clip in the library, not to an
instance on stage. Does this mean that the content can only be
something created during authoring with no possibility of modifying
it in Actionscript?

No, I had no reply and eventually wrote my own scroll pane
solution which allows me to directly modify the pane's content with
ActionScript and update the scroll bar to reflect any change in the
content's size. I'm puzzled by the help file's example in
ScrollPane.refreshPane() because it describes a senario where:
"for example, you've loaded a form into a scroll pane and an
input property (for example, a text field) has been changed by
ActionScript. In this case, you would call refreshPane() to reload
the same form with the new values for the input properties."
Which implies that you can use ActionScript to change the
content then reload it. The help file on ScrollPane.contentPath is
not very clear about what content can be used but appears to say
that the only content types allowed are: a SWF or JPEG loaded via
its URL or a symbol in the current library. I don't see how you
could use ActionScript to change any of these. I've tried
specifying an on-stage instance as the content but that
fails.

Controlling movieclip playback in Scroll Pane Component

Scroll pane height

I need to set the height of a scroll pane to the sum of heights of all the child elements in it. i.e i have a scroll pane and the content of the scroll pane is vbox. The vbox has many elements in it. I want to set the scroll pane height to sum of the height of the individual cell items in it. Please let me know.
Thanks.

Should have said desirable not acceptable. The most desirable solution is to use standard layouts and components. But also very desirable is to not spend so much time on such a simple issue. So I have used the ScrollableFlowPanel and the static inner class was a simple drop in. The only thing I added was a call to the following to left align: setLayout(new FlowLayout(FlowLayout.LEADING));Thanks for the help.

Putting an image in a scroll pane

This is probably a simple question for most of you, but I need a little bit of help. How do I put a picture in a scroll pane?
The problem I have is that I can load an image and display it, that works fine. However, let's say I am making a new frame (I generally use JFrames), and I want to have a scroll pane in it. Let's also say I have numerous buttons around the edges (using a BorderLayout, or something). How do I load an image, draw the image on-screen and have it so that it only shows up in the scroll pane without the scrollbars disappearing?
I try to do it now, but for some reason the scroll bars of the scroll pane never show up. I can make the entire image be displayed by dragging the window edges bigger (the normal way you make windows bigger), and then I can see the entire picture. Unfortunately, the scroll bars on the scroll pane never show up if the window is too small to display the entire image. This is very puzzling, because I really don't know what I'm doing wrong. I have tried putting a panel in the scroll pane, and drawing on the panel, but still no scroll bars show up on the scroll pane if it is not big enough to show the entire picture / panel.
I am sure that the solution is very simple, but right now that solution eludes me.

There's an example in the swing tutorials that seems to me to do exactly what you want.
See if http://java.sun.com/docs/books/tutorial/uiswing/components/scrollpane.html does the job, (less the border layout and buttons of course, but that shouldn't be too hard once you get the scroll bars working).
I believe the default scrollbar policy will let the scroll bars appear only when needed based on the bounds and the preferred size.
I used the example to set up a scrolling map (still just a gif image) and it works fine. If you still have trouble, you probably need to post the relevant section of code.

Scroll pane color for xp look and feel

hi
I am using the xp look and feel for my intranet application. Everything looks great, except for the colors of the scroll pane (added in a table) which still remains brown. I have tried setting the colors of the scroll pane, but nothing seems to work. Where is it that i am going wrong?
Thanks

Use this
table.getParent().setBackground(Color.BLUE);

How do you enable Auto Scroll in a sequence pane, and MIDI devices?

Hello,
I am just getting used to Garage Band for the first time. I am finding that Garage Band is much easier to deal with than Mark Of the Unicorn from a musical standpoint.
I am now converting my many MIDI sequences to GB. I have run into these three issues that I cannot seem to figure out.
1. I have both the "Main Secuence" pane and the "Piano Roll/Score" pane arranged vertically. But the Secuence pane auto scrolls, as the timing progresses, but the "Piano Roll/Score" pane does not. How do I get these two windows to enable/disable auto scroll?
2. How do I select from a starting bar to ending bar, for a given track, coping it, and pasting it to another track in the another track's sequence point?
3. How do I add other MIDI decices that I have pysically connected, and assign specific tracks to these physical MIDI divices and their defined Timbers?
Thanks in Advance.
Jeff Cameron

Thank you very much, Cristoph!
With your help, you have answered both questions 1 and 3.
Concerning question 2, I can see that when I click on the track header, the entire track is selected, but I am trying to physically select from one bar to another in that track.
I've tried clicking on the start bar and draging to the end and releasing. The whole track is still selected.
I've tried holding down the Shift key and doing the same. Still the whole track is still selected.
I guess I am missing the basics of marking and selecting the start and end point from within a basic track.
I'm already much farhter along with your help, and I appreciate your help, very much!

Use "next" and "previous" buttons in two scroll panes

Hello, I have a question about how to use next and previous buttons in two scroll panes. In fact, I plan to display two similar files (HTML) in two scroll panes seperately. the purpose is to find their differences, highlight these differences and finally traverse these differences one by one by using next and previous buttons.
To realize this function, how should I mark their differences so that next and prevous buttons can recognize their locations? does anyone have idea?
Thank you very much.

Can "focus" resolve this problem? But how should I add focus to a line in one HTML files? Thank you.

New to Applets: Problems wiht writing to files and with scroll panes.

Hi, I've recently graduated from university and so I have limited experience in java programming and I'm having some trouble with JApplets (this is the first time I've made one). I'm trying to make a simple program that will allow users to pick one of a few background images from a list (a list of jpanels within a scroll pane) then at the click of a button will output a CSS with the background tag set to the image location. This is for use on a microsoft sharepoint site where each user has a My-Sit area which I want to be customizable.
So far I've been creating this program as an application rather than a JApplet and just having another class that extends the JApplet Class which then displays the JFrame from the GUI Class. This initially didnt work because I was trying to add a window to a container so I kept programming it as an application until I got it working before trying to convert it to a JApplet. I solved the previous problem by changing my GUI class to extend JPanel instead of JFrame and it now displays correctly but with a coupe of issues.
Firstly the applet will not create/write to the CSS file. I read that applets couldnt read/write to the users file system but they could to their own. The file I wish to write to is kept on the same machine as the applet so I'm not sure why this isn't working.
Secondly the scroll panel is no longer working properly. This worked fine when I was still running the program as an application when the GUI still extended JFrame instead of JPanel (incidentally the program no longer runs as an application in this state) but now the scroll bar does not appear. This is a problem since I want the applet to remain the same size on the page even if I decide to add more backgrounds to the list. I tried setting the applet height/width to smaller values in the html file to see if the scroll bar would appear if the area was smaller than the GUI should be, but this just meant the bottom off the applet was cut off.
Could anyone offer any suggestion as to why these thigns arnt working and how to fix them? If necessary I can post my source code here. Thanks in advance.

Ok, well my program is made up of 4 classes, I hope this isnt too much to be posting. If any explaination is needed then I'll post that next. Theres lots of print lines scattered aroudn due to me trying to fix this and theres some stuff commented out from when the program used to be an application isntead of an applet.

Scroll pane refresh content

I have background in as3, but this is my first attempt at
building an application with classes.
I have a scrollpane that populates with an image.
MyScroll.as
public var sp:ScrollPane=new ScrollPane();
public var imagePath:String = "images/cover.jpg";
public function createScrollPane(imagePath:String):void {
sp.move(0,40);
sp.source = imagePath;
addChild(sp);
I have a navigation at the bottom that returns the image name
from an array that I want to refresh/load/source the scrollpane
with, but none will work!
SpreadNav.as
public function _loadPage(evt:MouseEvent) {
var str:String = evt.target.name;
var mySlice = str.substr(10);
myLoadImages.loadImage();
myScrollCall.reCreateScrollPane(myNpXMLToArray.highArray[mySlice]);
I also have a button generated that does reload the
scrollpane, so I know that it can replace the source.
MyScroll.as
public function setClick():void {
var refreshButton:Button = new Button();
refreshButton.emphasized = true;
refreshButton.label = "refreshPane()";
refreshButton.move(10, 10);
refreshButton.addEventListener(MouseEvent.CLICK,
clickHandler);
addChild(refreshButton);
public function clickHandler(event:MouseEvent):void {
sp.source = "images/1.jpg";
But when I try to load it from the array nothing
happens...and I have tried putting the image name right in there,
from the array, refresh, source, contentPath is old, redraw(true)
is old and I am running out of things to try
MyScroll.as
public function reCreateScrollPane(imagePath2:String):void {
//imagePath2 = "images/cover.jpg";
var url:String = "images/"+imagePath2;
trace(url);
sp.load(new URLRequest(url));
trace("scroll pane refreshed");
sp.addEventListener(ProgressEvent.PROGRESS, progressHandler);
sp.addEventListener(Event.COMPLETE, completeHandler);
sp.source = "images/"+imagePath2;
//sp.source = "images/cover.jpg";
Can anyone suggest a solution?
Thanks

i wonder why i bother with this forum sometimes. i always end
up answering my own questions an hour later. so the problem was
that the testes.swf was using a startDrag function and the
scrollPane in which it resided has its startDrag set to true. i
guess you can't have both elements dragging at the same time. would
cause serious upset. so yeah, there you go.

Remove/Hide scroll bars in scroll panes.

Hi all,
I am pretty new to action script. I am building a photo gallery and I am loading the thumbnails from an XML file into a scroll pane dynamically. As the scroll pane fills up, it gets wider to accomodate the thumbnails. There is one row, and eventually, I want to have the user be able to mouse left or right and have the scroll pane scroll, versus clicking on the bar or the left/right arrows. However, in order to accomplish this, I need the scroll bars to disappear!
Is there anyway to either remove or hide both the x and y scroll bars on a scroll pane? My scroll pane is called: thumbPane.
Thanks in advance!

THANKS.

IS IT POSSIBLE TO ADD A SCROLL PANE TO A PANEL??

Hi, Im trying to add a scroll pane to a panel but when I compile the code and try to open the form - a 'Illegal Argument Exception' is produced. Can anyone tell me whether it is possible to add a scroll pane the actual panel itself and also the code to do this.
Many Thanks, Karl.
I have added some sample code I have created -
public RequestForm(RequestList inC)throws SQLException{
          inRequestList = inC;
          displayForm();
          displayFields();
          displayButtons();
          getContentPane().add(panel);
          setVisible(true);
     public void displayForm() throws SQLException{
          setTitle("Request Form");
          setSize(600,740);
          // Center the frame
          Dimension dim = getToolkit().getScreenSize();
          setLocation(dim.width/2-getWidth()/2, dim.height/2-getHeight()/2);
          getContentPane().setLayout(new BorderLayout());
          Border etched = BorderFactory.createEtchedBorder();
          panel = new JPanel();
          panel.setLayout( null );
          //panel.setBackground(new Color(1,90,50));
          Border paneltitled = BorderFactory.createTitledBorder(etched,"");
          panel.setBorder(paneltitled);
          scrollPane1 = new JScrollPane(panel);
          scrollPane1.setBounds(0, 0, 600, 740);
          panel.add(scrollPane1);
}

Hi all,
I am still having trouble here. would it be posible to add a scrollpanel to this form? Can anyone provide me with a working piece of code so I see how it actually works.
Any help would be greatly appreciated.
Many Thanks, Karl.

     JLabel amortBox = new JLabel("Amortiaztion Table");
     JScrollPane amortScroll = new JScrollPane(amortBox);The argument passed to a JScrollPane constructor specifies what's inside the scroll pane. Here, it seems like you're trying to create a scroll pane that displays a JLabel.
Also, I'm not sure what you're trying to do here:
amortScroll(showAmort);I don't see a method named "amortScroll".
You need to make a JTextArea, pass that into the JScrollPane's constructor, and add the JScrollPane to your frame.

Specifying text font in a scroll pane

Below is a fragment of code that attempts to display text in a scroll pane. Basically this works OK, except for the following:
1. Changing the font doesn't seem to make any difference. I tried "Arial", as shown, and "Curier", the display looks identical in both cases.
2. Multiple blank spaces are replaced by a single blank space. So that "Baa baa" is displayed as "Baa baa".
I would like to be able to display messages with many lines of text in a scroll pane preserving the format if possible, which relies on the blank spaces. I hope you can suggest how to do this better.
Thans for you help.
Miguel
    JLabel label = new JLabel(text);
    Font font = new Font("Arial",Font.PLAIN,12);
    label.setFont(font);
    JScrollPane scrollPane = new JScrollPane(label);

try using a textArea instead of a label and include tabs for your multiple spaces.
import java.awt.Font;
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTextArea;
public class FontTest extends JFrame {
     public FontTest() {
          super("Font Testing");

          JTextArea text3 = new JTextArea();
          text3.setText(text);
          Font font = new Font("Courier",Font.PLAIN,12);
          text3.setFont(font);
          JScrollPane scrollPane = new JScrollPane(text3);
          getContentPane().add(scrollPane);
          setSize(400, 200);
          setVisible(true);
     public static void main(String[] args) {
