Hi got a little question about sizes an anchoring.
Sometimes result is not what expected and donr really know why.
If i put a couple of jedit width to wrap content one with no anchors
other to anchor first one. At rigth-of and baseline.
First with parent relative abxhor. Top and left.
Do same with another couple. But to anchor both couples i anchor first
of second pair to first of first. Anchored left and below of.
Shows ok.
Then change first of second anchor to second of first.
Left anchored relevtive to parent and below-of second of first pair.
Shows on top of second.
Why?
Is there some place i can check hierarchy of anchoring relations?
Thanks

Hi amartitegui,

I also encountered this problem and had a bit of a nightmare getting
my anchoring right, setting below when they should have been above
etc.
The way that worked for me was setting one main anchor and basing
everything else off that anchor tended to work better. So BTN1 is the
main anchor, then BTN2 below, set that to raBelow with BTN1 as the
anchor, BTN3 to the right of BTN2 (raToRightOf/raAlignBaseline), with
BTN2 as the anchor for BTN3. As you can see, base each anchor from
BTN1, hope this makes sense. This could be an issue if you needed a
button further away, but I would just use margins and +- away from the
last anchor I needed. Not ideal but it works!
I found using more than one anchor independently resulted in the x and
y going off the chart, so to speak.
You're not alone I have spent many hours on this
My LAMW app is here:

You should be able to see my anchoring on the screenshots there.

See the image.
Ill talk about the white labels as textboxes(even if they are all
jtextview)
I have a panel (with a header saying CONFIGURACION INTERIOR). wanna
size heigh to wrap content ('cause some labels can become two liners).
modelo is anchored to configuracion interior (below of) and parent
left.
I tried color label to be anchored to modelo-textbox below of and
anchored to parent left.
same with herraje, and tapajuntas pairs (label+textbox).
WHY,
because when sizing textboxes, if they become two liners... dont want
to overlap one over the next.
....
well im gonna try something.
thanks
