Scroll Bar Position

I have an applet which will display 25 columns and n Number of rows. How can I change the cursor postion to a particular row while applet reloads?
setRowSelectionInterval(int, int) may move the cursor to the particular row. But The scrollbar is still in initial position. I need to change the scroll position.

Use getCellRect(...) to get the rectangles of any cells you want to display, then create a Rectangle which circumscribes all of these, then use scrollRectToVisible(...) to adjust the view.

When and How to get the Text.ScrollPos value of a String control when scroll bar position changed

Hi,
I'm working on a feature triggered by scroll bar position of a string control changed.
But I could not find a good way to catch the scroll bar position changed event,
the scroll bar is controlled manually by mouse down → mouse move → mouse up, I want the get the Text.ScrollPos value when user mouse up, and compare with the maximum value.
But the problem is, mouse up on the scroll bar could not trigger String: Mouse up event!
So I have to get the Text.ScrollPos continuously in the background in Timeout event, but I think it’s not efficient.
Do you have any better idea on when to get the correct destination value of Text.ScrollPos?
I plan to store the value of Text.ScrollPos in the bottom(maximum value) in a shift register, then compare the current Text.ScrollPos value with the max one.
If it comes close to the bottom(90%~100% of the maximum value), then the close to bottom LED will turn on.

Hello Cecilia,
I don't think there is any build-in event for this.
One solution would be to create your own user event at the initialisation of you main and launch a thread which is going to be pulling the value of your scrollbar position:
Then you can build your main as if they were a scrollbar move event.
And dont forget to close the thread and destroy the event at the end.
Hope it helps.

Custom Horizontal Scroll Bar position on File Open

Fellow Forum Members,
I have a lot of PDF files that I want to open in a special way. I want them to open at 150% ZOOM and this was easy enough to setup in the PREFERENCES window.
However, what is proving to be a big problem is changing how the horizontal scroll bar has a default position all the way to the left. My objective is to have the horizontal scroll bar positioned all the way to the right and at a 150% everytime I open a PDF file.
The Preferences window doesn't seem to have a horizontal scroll bar position on open setting. Can anyone help me out and tell me how such a custom setting is possible with Acrobat 9 Extended? Any help will be greatly appreciated. Thanks.

Does anyone have any ideas?

Get image Scroll bar position value

How to get an image component scrollbar position value in flex.
I have an image component in my application, when i scroll the horizontal scrollbar
i need the current scrolled position. How to get the scrolled position in an image component.
Kindly help in this issue.

Are you sure you want to use setOnScroll to listen to scroll events rather than set the value of the scroll bar position via the tableView.scrollTo api (which I would recommend) or the scrollBar.setValue() api?
for (Node n: table.lookupAll(".scroll-bar")) {
if (n instanceof ScrollBar) {
    ScrollBar bar = (ScrollBar) n;
    System.out.println(bar.getOrientation() + ": range " + bar.getMin() + " => " + bar.getMax() + ", value " + bar.getValue());
      if (bar.getOrientation().equals(Orientation.VERTICAL)) {
      bar.setValue(0.5);
}If you did really, really want to use setOnScroll, then you could do something like this:
Node flow = table.lookup("VirtualFlow");
if (flow != null) {
final EventHandler<? super ScrollEvent> originalScrollHandler = flow.getOnScroll();
flow.setOnScroll(new EventHandler<ScrollEvent>() {
    @Override public void handle(ScrollEvent event) {
      System.out.println(event);
      originalScrollHandler.handle(event);
} Though you would be better off just using an eventfilter rather than using the strange lookup and setOnScroll chaining method in the above code.
table.addEventFilter(ScrollEvent.ANY, new EventHandler<ScrollEvent>() {
@Override public void handle(ScrollEvent event) {
    System.out.println(event);
    // uncomment if you don't want the default table scroll events processing to take effect.
    //event.consume();
});

ScrollPane vertical scroll bar positioning

I have a ScrollPane that holds a number of number of sprites. The sprites are like rows and I would like them to fill the width of the ScrollPane.
My problem is that if there are not enough sprites to fill the vertical space of the ScrollPane, then no Scrollbar appears and there is a narrow gap left on the right side of the ScrollPane. If I make the sprites wider, when the vertical scroll bar does appear some of the sprite is cut off and the horizontal scroll bar appears (I never want the horizontal one to appear).
Is there a way to move the scrollBars? or perhaps another way to solve my issue?

assign your sp's horizontalScrollPolicy (and/or verticalScrollPolicy) to "off".

DataTable Scroll bar Position Changing

Hi,
I have a datatable with scroll bar on 'A' screen and when I go to 'B' screen and come back to 'A' screen again the data table reloads and showing the table from the first record onwards instead of showing the selected n th record by holding the scroll bar state.
Is there any way to scroll the scroll bar of a data table to the particular record either by backend logic or by java script.
I used h:PanelGroup to the data table for scroll bar.

That's getting harder. Put the tables in a block element, e.g. div, and onload set div.scrollTop to the amount of pixels it have to be scrolled. I am not going to give raw code here as you're here in a Java/JSF forum, not a Javascript/DHTML forum. If you still stucks, even after googling on the given keywords, consult DHTML forums like dhtmlcentral.com and dynamicdrive.com.

Hello.

A few user has the same prolem like me T.T when I checked other users is using Ipad mini or related Ipad series on web.
and I could not find solution for it,
The probelm is : the horizontal scroll bar position is changed as below image, the scroll bar appears in the middle on web page of Safari
after zoom the page out and moving.

I already did it with a few way to fix and it never fix in my side.
- Resotre factory mode : still happened.
- Turn off and on Ipad mini : still happened.
- Clear Cooke and data in safari setup.
If Clear cooke and data, it just disappeared on web surfing but this is only temporary way, I could meet the problem soon on web surfing.
Please help me to fix and share some information for it.
Thanks.

I am having the same issue. Went to the Apple Store in Boston and the Genius Bar escalated the problem to the Engineers and they could not even solve it. They needed me to send them an image of the issue. I went to another Apple store and the Genius there had much better problem solving skills. He used his own critical thinking and discovered that the horizontal scroll bar sits at the same height. The height is exactly where the split keyboard ends. If you take screen shots and compare...you will find they are all at the same height. He thinks since the keyboard is a new feature they havent worked out the problems yet...and we will have to wait for the update.
Ever since Steve Jobs has been gone the call to response for issues is getting increasing slower and slower. New products continue to roll out but they all have problems and bugs. Take Maps for instance...they still have not fixed all the issues (even with this 6.0.1 update). The Ipad mini I spend 700$ for and it is such a faulty product. For what I spent I would have thought I would have gotten a great product. I have all Apple products...phone, desktop, laptop, Ipad original, and Mini...but they have done me wrong over and over. It may take months for them to roll out the fix the way the compnay has been operating under Cook.
When will the fix come....I do not know... best of luck!

Mobile table scroll bar issue

Hello All,
I have used sap.m.Table on my mobile app page and I have set growingScrollToLoad to true.
Everytime I scroll the page down, table loads more and more data, but the scroll bar position moves to the top automatically.
This is very annoying because after getting bigger set of data, my scroller moves back on top and I have to move it all the way down to where I was.
Any ideas as to why the scroll bar moves up automatically and how to prevent it?

Hi Frank,
I have found the answer. Here it is for anyone who would ever have or meet the same issue.
In Jsf table property inspector
I binded my table to my java bean (I called it myRichTable).
I added the First and Last buttons as partial triggers of my table
In java bean
In my last() method I encluded the following line of code: myRichTable.setDisplayRow(myRichTable.DISPLAY_ROW_LAST).
And in the first(): myRichTable.setDisplayRow(myRichTable.DISPLAY_ROW_FIRST);
Thanks!

Put a scroll bar at left side

Hi all,
I'm trying to change the side of a vertical scroll bar is set
on a datagrid,
e.g.: the defaut side is right and I want to set this
vertical scroll bar on left.
Thank you everybody,
Artur

The vertical scroll bar position in a datagrid is set in the
updateDisplayList function.
what you can do is extending from datagrid and add the
following code:
override protected function
updateDisplayList(unscaledWidth:Number,
unscaledHeight:Number):void
super.updateDisplayList(unscaledWidth, unscaledHeight);
verticalScrollbar.x = 0;
this code example will only move the scrollbar to the left,
but i guess you will also have to adjust the content position.
if you can't access the attribute verticalScrollBar from you
new class, add the following code above the class definition:
import mx.core.mx_internal;
use namespace mx_internal;

How do i add a Scroll Bar to a JList Component using absolute positioning?

I've got a applet whose content pane is set to null. I've create a jlist component on this applet and using absolute positioning set the bounds at
ListBox1.setBounds(380,10, 500, 500);.
My problem is creating add a scroll bar to the list box.
JScrollPane scrollPane = new JScrollPane(ListBox1);
C.add(scrollPane);
The above code is what i use and when i run this applet i don't see the list box at all. How do i add a scrollbar to this list box or JList component. Please help.

You need to setBounds() on the JScrollPane, not the JList.
The JScrollPane is the component that is being added to the panel.

Return to initial position when dragging scroll bar

There is a function in Windows that when using mouse cursor to drag the scroll bar, moving the cursor away from the scroll bar makes the bar go back to its initial position. Does OS X have a similar function? It is useful when looking figures during reading a large document.

Send Apple feedback. They won't answer, but at least will know there is a problem. If enough people send feedback, it may get the problem solved sooner.
