View Full Version : [FIXED] scrollIntoView
22 Jul 2008, 6:42 AM
scrollIntoView in a DataView doesn't work. Easy to see this in a ComboBox where the popup contains a scroll bar. As you press the down arrow key, the next item gets selected but it'll go right past the visible area without scrolling.
I noticed that the code in the base class... sorry, I don't remember which class, has
everything commented out for scrollIntoView.
Any thoughts on when this will be done?

Fix is in SVN.

Seems to work fine in 1.0.2 for ComboBox. But it doesn't seem to work
when there's simply a DataView in a LayoutContainer with scroll mode
set to AUTO.
Sorry I didn't provide code -- but I'm wondering if this use of scrollIntoView
has been validated? If so, can you provide a simple example. It's certainly
possible I've done something wrong, but not sure where.

Scroll into view will not work if is the DataView's parent container that is scrolling. The DataView itself should be scrolling.

There is no way to set the scroll mode on a DataView. I have the scroll mode set to Scoll.Auto on the parent LayoutContainer, and I am calling scrollIntoView on the DataView instance, passing the DataViewItem I wan't to be visible as the parameter. It doesn't work. Am I doing it wrong?

A very critical part of this was missing. I looked at the ComboBox code to figure it out. The base scrollIntoView code does not do the job. I had to override that method in my DataView in order to pass it the scrolling parent. It works, but I don't think it should work that way. The scrollIntoView should grab the parent on its own IMHO.
Anyway, all is working now.

DataView extends Container which is wrong. I have changed DataView to extend ScrollContainer. Change is in SVN.
