Re: Style issues with VerticalPanel vs FlowPanel
Hi Dave,
you could:
a) allocate your anchors to the VP in a method that calls the required
Vp setCellHeight(widget,height) method conveniently, e.g.:
private void addAnchor(MyAnchor anchor) {
myVP.add(anchor);
myVP.setCellHeight(anchor,nnpx);
}
b) use a Grid with one column. Grid extends HTMLTable which has a
ColumnFormatter with which you can apply your required height to all
the cells using CSS. Note Grid needs to be sized up front, so it not
always so convenient if you need to allocate items to it on the fly at
run time (although you can add cells to it explicitly).

be home free. Anyone got a code snippet for this?

Ideas?

Re: Style issues with VerticalPanel vs FlowPanel
Damn, I spoke too soon. The code compiles cleanly, but
doesn't have any visual effect at all. [The cellsize parameter is
a string, so I'm using stuff like 10px or 50px, right?]
Tried making cellsize BIGGER...no effect. Smaller, no effect.
[Something else must be in charge...the fontsize of the text of
my widget (an anchor)?!?!]
I'm still missing somthing!

Thanks for the confirmation! (I finally deduced as much, after
posting, that while one can set border size once before or after
creating
the VP, but that one must set the CellHeight for EACH cell
since each cell could even contain a different widget type...hence the
widget-arg.)
And, I also just ran across the 'grid' UI-object after posting, and
kinda figured
that it might fit for me. What has been eluding me when reading the
API
docs is that, when I don't see the expected method I want, that I need
to look further down into sections on methods inherited from more
general object types. (Been just a bit too long ago that I did any
serious Java-coding...sigh)
My brain is slowly starting to understand these APIs...and they
are SWEET once mastered!
Thanks again for replying.
Cheers...

Re: Style issues with VerticalPanel vs FlowPanel
Ok, finally solved it.
I had my own project-specific .CSS file with default values for about
every html element that exists! Removing it didn't help...some other
default
values (that Google supplies?) were still in effect.
But, the fix was to go into my proj-specific .CSS and make all table-
elements
have 'padding' of '0px' (previously, I had '1em') This is no doubt
needed for
a 'VerticalPanel', because a VP gets implemented via some hidden
'table',
so the table-element styles effect it.
So, I'm now able to move on to more important stuff.
(Whew!)
