Re: ScrollPanel maxWidth or maxHeight?
I don't know if it still relevant, but I had the same problem and I found a
solution.
I have small popup (my Class extends DialogBox).
Inside the popup, I have a VerticalPanel. Inside this panel is a ScrollPanel
and a HorizontalPanel for some buttons. Inside the ScrollPanel is a
FlexTable.
Now, the user can add and remove rows in the FlexTable. I want to grow the
Dialog a bit, but when it gets too large, I want the ScrollPanel to have a
fixed height so that the scrollbars appear.
When the user removes elements from the table and gets beyond the critical
height, I want the dialog to shrink.
It's quite easy. Here is how I achieved it.
private void handlePanelHeight() {
String height = null;
if (table.getOffsetHeight() MAX_PANEL_HEIGHT) {
height = String.valueOf(MAX_PANEL_HEIGHT);
} else {
height = String.valueOf(table.getOffsetHeight());
}
DOM.setStyleAttribute(scrollPanel.getElement(), height, height);
}
In my example, I set MAX_PANEL_HEIGHT to 250.
I call this method when
- the dialog is opened
- the user adds a row
- the user removes a row
I hope this helps.
Best regards
Denny

Re: ScrollPanel maxWidth or maxHeight?
I see, I will try it - thank you all for your help. On 6 Feb., 19:32, gregor greg.power...@googlemail.com wrote: Oh right... I think you've got to make sure that the whatever the ScrollPanel contains has actually reduced in size already - if it hasn't the ScrollPanel will refuse to cooperate (i.e. it won't squash it's contents by itself). Then you need to reset it to 1px more than the height/width of its contents (1px is fine if contents is now 0) in order to get rid of the scroll bars (0px etc is ignored as I recall). It won't do that by itself. After that you'll have to try things out - I've always reset ScrollPanel's to a specific height after this procedure, so I don't know how to release it from the 1px instruction without specifying another. I think I would use debugger to find out exact style properties of ScrollPanel whilst it's in growing mode to start with, and attempt to replicate that. If it has nothing in height/width you may have a problem because, as you say, you may not be allowed to actually remove a style attribute once it's there, only modify it, in which case the ScrollPanel may stubbornly refuse to cooperate. You might be forced to attempt a detach of the items widget, replace ScollPanel with a new one, and reattach the items widget to it, or some such... or you might consider another way to do this altogether - ScrollPanel's can be tiresome, uncooperative widgets at times ;-) On Feb 6, 3:46 pm, Davsket g.ave...@gmail.com wrote: well, at least replace it..

Oh, in your use case, Alex, you do have an event - adding an item to the panel.
