How to scroll page to element

[redlaber]

I want to scroll page, generated with gwt, to some element. Its should
be simple, but i cannt find the solution. For example: I have a
vertical panel with two flexables. When i get the history token
"goto2" I want to scroll my page to the second table. (Sorry for the
terrible english).

use ScrollPanel.setScrollPosition(). that sets the vertical scroll
position of the scrollpanel, which you will need to calculate. try
something like this:

new ClickHandler() {
public void onClick( ClickEvent event ) {
int tableTop = secondFlexTable.getAbsoluteTop();
scrollPanel.setScrollPosition( tableTop );
}
}

i suppose in your case it wouldn't be a click handler if you're basing
it off the history token, but hopefully this will point you in the
right direction.

So i must plaсe my VerticalPanel onto ScrollPanel?

The next problem: I have finished big gwt-application and I cant add a
ScrollPanel in it. But i know position of browser scrollbar, where I
want to jump (scroll). Is there no way to simply scroll through the
document to a given position?

I don't understand well your question, but why don't you use div to
separate parts from the page, and then call the div class that you
need??

I assume you're using GWT 2.0. If so dom.client.Element has a method:
"scrollIntoView" which may be what you are looking for.

To scroll to a Button for example:

Button button = new Button();
//...

button.getElement().scrollIntoView();

This will scroll any required elements (including ScrollPanels and the
document itself) to make sure that the Button is visible to the user.

Hope that helps.

This is exactly what I was looking for. Thanks much, Jason! I'll try
it tomorrow and write here the result.

You can get away without a ScrollPanel if you want to as well.  Something like:

verticalPanel.getElement().setScrollTop(secondFlexTable.getElement().getAbsoluteTop());

I've learned some things reading this thread. nice. :)

looks like there are some easier ways of doing things than how i'm
doing my scrolling, and this would probably be not the easiest, but
i'll mention it for completeness. it's also possible to do the
browser window scrolling in javascript, and make a JSNI call to the
javascript function to do it. i'm currently using this method to
simulate a page refresh:

function scrollToTop() {
window.scroll( 0, 0 );
}

and the corresponding GWT JSNI method:

public native void jsScrollWindowToTop() /*-{
$wnd.scrollToTop();
}-*/;

just one more option.
