Get scroll position

hey,
i'm using jdeveloper11g and I use a RichTable to display data of a ViewObject. The data associated with the view object changes and i need to update RichTable accordingly. However, as I update using Poll the scroll position of the table is changed to top most position. What i need is to preserve the scroll position even after the refresh...any hints would be a gr8 help
thanx

That's not as easy as it sounds :-(
As far as I know there is no method to get the scroll bar position itself.
The problem is to get hold of the position the iterator is in when the poll event occurs.
You execute the underlying query again to show new data. Depending on the query (i.e. sort) the result might be different after the refresh. The user might be confused about the new result, but I guess you thought out this.
You can play with this EL #{bindings.YourView.iteratorBinding.rangeStart}and save the value before you re execute the query and after execution set the position back.
Timo
P.S.:
I did not test this with scrollable views (which are the preferred views to use with faces). so you might allays get 0 as result. In this case you can try to save the current record (if you have one selected) and go back to this record after refresh.

Getting scroll position

I can read and write the zoom level of a document (doc.zoom). I can scroll to a specific point in the document (doc.scroll). Bu I can't read the current scroll position. Is there a way around this.
The scenario:
     I have 24 pdf documents each with a single page containing a picture.
     Each picture was taken with a fixed camera - one picture for each hour of the day. So the pictures are of the same thing - just separated taken at different times.
     On the 1:00 am picture I see something I want to examine more closely so I zoom and scroll to a particular portion of the picture.
     Now I want to see the same area on the 2:00 am picture. I can read open the 2:00 am picture and zoom to the same zoom level (by reading the zoom property of the 1:00 am document).
     But how do I get the the 2:00 am document to scroll to the same position as the 1:00 am document if I can't read the scroll position of the 1:00 am document?
My actual issue is more complex than this scenario but this illustrates the question.

In any case viewState only works with embedded PDF - which is not the scenario I have.
In some respects I want something like synchronized scroll but I am dealing with multiple documents. I open one document and zoom/pan to a particular spot. Then I want to open another document with the same zoom and pan. I will select the other document from a list which could have many dozens of documents. It is impractical to open all the documents at the same time.
One possibility I have not considered yet would be use Bookmarks. Bookmarks store the zoom level but I don't know if they store the pan.
What I want is something like the center point of the current view. This value could be passed to doc.scroll. Is there a parameter that gives the coordinates of the document view (not the screen coordinates - but the document coordinates? I could calculate the point necessary for doc.scroll from thse coordinates.

Adobe edge - get scroll position value

Currently I can get the mouse position and control the timeline with the x value.

this is very easy too !!
you just need to have little knowledge about jQuery and change your view ! the way you are looking into codes is not right and thats why you cant make easy things like this
here is code for 3 things
if ( c == 2 ){
sym.play("on1");
c = 3;
}else if ( c == 1 ){
sym.play(1);
c = 2;
else{
sym.play("on2"); // for third one
c = 1;
if you had any question feel free to ask

How to play a symbol ONCE at a specific scroll position?

Hello there,
I was wondering if it's possible to trigger a symbol to play when a user scrolls past a specific scroll point just once?
I've managed to create a trigger for a symbol which will fire at a specific scroll position but it fires multiple times (when the user continues to scroll)
I tried using:
'==' eqivalent to, so that it would only trigger at a certain scroll point, but this only triggers the symbol to play if the user uses their mouse scroll wheel and doesn't play if the user uses the window scrollbar.
Here's my code (apologies if it's messy I only started learning JQuery a week ago):
$(window).scroll(function() {
 var mySymbolObject = sym.getSymbol("rollHead");
 var y_scroll_pos = window.pageYOffset;
 var scroll_pos_test = 500;
 if(y_scroll_pos > scroll_pos_test) {
 sym.$("rollHead").show();
 mySymbolObject.play(1000);
 if(y_scroll_pos < scroll_pos_test) {
 sym.$("rollHead").hide();
 mySymbolObject.stop();
I know that the '.one' handler (if that's the correct term) can cause an event to trigger just once, but I can't seem to get it to work.
Any help or advice would be much appreciated.
Thank you very much.
Jon
P.S. I just want to say a MASSIVE thank you to Adobe for making Edge. It is an incredible tool and the fact that it is free makes it a million times better.

Hello Mr Blix,
I pretty much just copied and pasted what Elaine wrote.
So, I went to my stage actions - clicked 'composition ready'
And put in this:
sym.setVariable("symbolPlayed", false);
var mySymbolObject = sym.getSymbol("rollHead");
$(window).scroll(function() {
 var y_scroll_pos = window.pageYOffset;
 var scroll_pos_test = 500;
 if(y_scroll_pos > scroll_pos_test) {
var symbolPlayed = sym.getVariable("symbolPlayed");
if (!symbolPlayed) {
 sym.$("rollHead").show();
 mySymbolObject.play(1000);
 sym.setVariable("symbolPlayed", true);
All you'd need to change for you own composition (if that's the right word) is to replace:
var mySymbolObject = sym.getSymbol("rollHead"); - with your own symbol name.
var scroll_pos_test = 500; - with the position you want the event to trigger.
sym.$("rollHead").show(); - with your own symbol name again.
mySymbolObject.play(1000) - with the time on your symbol's timeline that you want it to play.
I'm still learning JQuery and don't really understand how the 'SymbolPlayed' works, but I assure you it does.
Here's a screengrab of my 'stage actions' code.
Hope that helps!

Chart Error - scroller positions should be positive and integer


Hello Expert
I have created a flash chart with two filters on the chart region.
i) ‘Select list with submit' ----- (:P23_TRC)
ii) ‘Radio button with submit' -----(:P23_IMPACTC)
The chart should display as per the filters selection.
However, I get the error message "scroller positions should be positive and integer", once, whenever I load this chart page for the 1st time in a new IE window.
After I change the filter's value it will work perfectly fine.
In filters default value is one value from respective filter list of value


If I remove the filter conditions from chart query, it works perfectly without error.
Here are my chart series queries

Help please!!!!! It's urgent
Sagar


Hi Rima,
I found the solution,
My graph is dependent on the page items. What I found was when I load the page, item default value was displayed but it was not stored in the memory. Item value only gets stored in memory when the page is submitted.
Line: -----
Soultion : - Create a page level before header process and define the default value over here as well. This will resolve your error.
Hopefully you understood what I am trying to explain. If not let me know and I will trying to put in picture and email you.

How to avoid blinking / moving of rows in a data grid when you restore the scroll positions

By Default when an update is made on a data grid, it scrolls to top row. To avoid this when we save the vertical and horizontal scroll
positions and restore the scroll positions after the update, it causes a blink in the grid (or moving / jumping) of rows. Is there a way to
avoid this jumping of rows?
In JavaScript this can be achieved by overriding the scrollToTop / OnLoad methods of datagrid to directly scroll to current scroll
positions instead of top row. Is there a way to achieve similar feature in flex / actionscript?

I am calling validateNow().. Also, using verticalScrollPosition to restore the scroller as in the link that you posted.. Reposition is working fine, But the bug filed is regarding BLINKING / JUMPING when this happens (i.e. this blinking is caused because after datagrid edit, during reload the scroller tries to move to the top by default, then it repositions itself to current edited row as the verticalScrollPosition property is overridden ).. I have to get rid of this blinking.
In Javascript it is dealt by overriding OnLoad method of datagrid to directly scroll to current scroll position instead of top row during reload so that there is no blinking.
http://www.sencha.com/forum/showthread.php?13898-Is-there-any-way-to-keep-scroll-position- of-Grid-on-load
Is there a way to achieve similar feature in flex?
I am not sure what flex datagrid method to override.. Theres no method like load? What is the datagrid method that is called by default during reload (after datagrid edit) that causes the scroller to go to top?

Accordion Widget not saving current scroll position

Accordion widget saves scroll position in Firefox, however in
IE7 the position gets reset to the center of Accordion Widget.
Example. Select Alabama and then select Wisconsin to see
effect.
See www.Qualite1.com/contactUs.html

Hi ghaug,
This is due to the tabindex attribute that is on the
top-level element of the accordion. Apparently when an element is
focused in IE, it tries to make sure the top of that element is in
view, so it is "conveniently" scrolling it into view for you.
To prevent this behavior for accordions like yours that don't
fit neatly into a single screen, you are going to have to remove
the tabindex attribute from the top-level accordion element. If you
still want/need keyboard navigation of your accordion, then you
have to switch to using links in your accordion tabs. You can find
an example here:

Last page scroll position not remembered

After getting search results in Google, I click on a subject, then when I click "back" it returns to the top of the previous page. It's like it doesn't remember where it was. One fix I found was to change cache-control in about:config. But I can't find it. Where is I located? Another fix is "Restore Scroll Position" does this work on ver 3.6.12 ?
TIA

It is usually easier to open the results in a new tab with a middle click on the link and close that tab with a middle click on that tab on the tab bar.
For the Google website you can set your preferences on the Google.com page via the [http://www.google.com/preferences?hl=en Google Search settings] link at the top right.

WebView scroll position

How can I get and set the vertical scroll position for a WebView?

You mean something like:
webView.getEngine().executeScript("window.scrollTo(100,100);")That didn't have any effect as far as I could tell.
Any good reason why there isn't a Java API?

Scroll Position

I have a working listener on a mock scroll bar, but I get
results that are not correct. I was hoping that somebody knows how
I could get the position of a scroll bar through an actionscript
alert or by binding it to a coldfusion form.
As shown in the code below, I am using "vScroll.vPosition" to
return the position.
The code below is ready to run just copy and paste onto the
server to see my problem.
Thanks for your time.

Scroll Position ReportViewer

Hello,
is there a way to retrieve and set the scroll position (Horizontal and Vertical of course) of the WinForm CrystalReportViewer.
I tried everything (includinng the analysis of the controls of the control CrystalReportViewer) and none of the controls of CrystalReportViewer or the control itself have the Property VerticalScroll.Value filled, it always contains the value 0.
I also tried to step into the scroll event but it is not raised.
My application is a WinForm Application and I use CR2008 with Oracle.
Thank you.
Giovanni Perrone

I remember putting this together for someone else a while back. It's been a long time since I've run this code so I give no warranty with this solution. I believe the trick was getting into the Form_Paint event, then accessing a specific TabControl for the CrystalReportViewer.
It was very much a trial and error solution.
Give it a try and see if it helps you out.
Note: This is also address in this thread How to Set , Get CrystalReportViewer Scroll position in .NET.
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
namespace cr12_modify_viewer_scroll_position
    public partial class Form1 : Form
        public Form1()
            InitializeComponent();
        private void Form1_Load(object sender, EventArgs e)
            crystalReportViewer1.ReportSource = Application.StartupPath + "\\..\\..\\CrystalReport1.rpt";
        private void Form1_Paint(object sender, PaintEventArgs e)
            MessageBox.Show("Form1 Paint");
            // get the tab control
            TabControl boTabControl = (TabControl)crystalReportViewer1.Controls[0].Controls[0];
            TabPage boTabPage = boTabControl.TabPages[0];
            boTabPage.VerticalScroll.Value = boTabPage.VerticalScroll.Maximum / 2;
            crystalReportViewer1.Refresh();

JScrollPane - can you set scroll position?

I have a JList loaded into a JScrollPane, and I call a method that highlights a row of the JList, but I can't figure out how to get the JScrollPane to scroll down.
Is there a method where I can manually set the scroll position? I looked at the documentation online and didn't see anything like that.
Thanks.
-Mark

You need to get a reference to the JScrollPane's JViewport
myPane.getViewport();
Then on the viewport you can call one of these.
scrollRectToVisible(Rectangle contentRect)
setViewPosition(Point p)
Cheers,

DataGrid scroll positions resetting with dynamic dataprovider

Hi - I have a DataGrid that is backed by an ArrayCollection
that is fairly dynamic. Before doing my updates, i disable
autoupdating, and though my size is typically fixed at 100 items,
sometimes those items will be replaced. My problem is that a user
who has scrolled down the visible grid, will lose their scroll
position when i replace items. If i'm just doing updates on the
existing objects, it's fine, but the replace is causing the scrolls
(both horizontal and vertical) to reset. I've tried to isolate
where this is happening (whether set verticalScrollPosition or on
the bookmark) and i can't quite find it.
Anyone know how i can prevent this behavior? I've tried
capturing the scoll position before i begin my updates, and then
setting it back when finished, but it doesn't work.
Thanks.
./paul

Actually, I spoke too soon. I had a number of things I was
trying. And when i tried to clean up the other things that I
believed were extraneous (including an override of
makeColumnsAndRows), the vertical scroll resetting stopped working.
I've spent about 90 minutes trying to get back to where I was (wish
the builder was in IntelliJ!).
When it was working, I also tried to add horizontal scroll
capturing, and that didn't seem work either. I have 34 columns, the
first one is locked. When I captured my position, I saw it was 11.
Then i performed the update, and callLater my resetScroll position.
The first column i saw after the locked column is correct. However,
the scroll bar itself is fully left. On the next update I captured
a horizontal scroll of zero.
