ScrollTable scroll position

[ivovnenko]

Hello everyone.
Is there any way to set scroll position in incubator's ScrollTable?
The use case:
I'm adding the element to the bottom(top) of the ScrollTable, and I
want it to be selected and visible - need to scroll to its position.
Thnx

Did you gave a look at the ScrollPanel's javadoc (or your IDE's auto-
complete suggestions)?
- ensureVisible(UIObject)
- scrollToBottom / scrollToTop
- setScrollPosition(int)

Well, haven't noticed such methods in ScrollTable...

They were added in GWT 1.5. So if you are using a 1.4 version or lower
they do not exist.

I'm using gwt1.5, and don't see such methods in ScrollTable.

Well, don't know what to tell you. It's there, I use it myself. Here
is a link to the javadoc that says it exists.

Guys, I'm talking about ScrollTable, not ScrollPanel!

Ah sorry about that, that's an incubator component. Seems really easy
to do with a verticalpanel and a scrollpanel...

Yep, sorry, just noticed...

Workaround attempt (untested):

// Adapt the fully-qualified class names if you're using the gen2
version
class ScrollTableUtils {
private static native Element getDataWrapper(ScrollTable table) /*-
{
return
table.@com.google.gwt.widgetideas.table.client.ScrollTable::dataWrapper;
}-*/;

private static native void scrollTables(ScrollTable table) {
table.@
com.google.gwt.widgetideas.table.client.ScrollTable::scrollTables(Z)
(false);
}

public static void scrollTo(ScrollTable table, int x, int y) {
Element dataWrapper = getDataWrapper(table);
dataWrapper.setScrollLeft(x);
dataWrapper.setScrollTop(y);
scrollTables(table);
}
}

Note that you could also derive ScrollTable to add the above methods
(scrollTables is protected, so you don't have to use JSNI to call it
if you follow this path)
