Flow Layout Flaw? - rightSample.vu (1/1)

Ok I have a composite view that uses the flow layout. In this view I
have 2 push buttons. I have a horizontal gap of 10 and and alignment of
#right. My first button remains on the screen but the second button is
clipped and halfway hidden.

Instead of

-------------------------
+--------+     +--------+
!    1   !     !    2   !
+--------+     +--------+
-------------------------

I get
-------------------------
     +--------+     +----
     !    1   !     !  
     +--------+     +----
-------------------------

Using Win2k. What I want is an easy way to stack a row of buttons with
right alignment. Attached is the .vu file.

It looks like the FlowLayout doesn't take into account the horizontalGap
setting when calculating it's left offset, using the centre alignment is not
quite correct either.

I know it's a little more work but I usually use a FramingLayout for things
like that. You can position one button absolutely (the top right one from
your description) and then position all the others with reference to that.

You might also be able to use a GridLayout by dropping another container
onto your existing one, right aligning it and giving it a Grid layout
manager. Setting the rows and columns aspect for this should allow you to
create a column, or columns, of buttons.

If you really do want a FlowLayout though, so the number of buttons on each
row changes as the containing view is resized, then you'll probably have to
wait for a fix to FlowLayout.  You might <untested musing alert> be able to
create a subview containing a button enclosed in it's own container with
appropriate whitespace. Adding these to a FlowLayout, with a horizontalGap
of 0, might get the effect you want?

That's what I'm using right now but it seemed like using Flow would be
easier. So I should report this as a bug?

It depends a lot on what you want to do but you are probably right about
FlowLayout being easier.

A temporary fix that seems to work is to modify
FlowLayout>>startOffsetFor:in: and add the following line immediately after
the existing line that sets the lineWidth

lineWidth := lineWidth + (anOrderedCollection size - 1 * hgap).

This just moves the left hand edge a bit further across, allowing for the
extra hgaps. NB. It's not a proper fix but it might be enough to get you
going with FlowLayout.

Hopefully Andy or Blair will read this thread <FX> Waves hand and call
"coooeeee" </FX> so you probably already have !!

Have you looked at the Wizardry package in my 4.01 goodies?  It tries to
take some of the tedium out of setting framing constraints (see the loose
methods), and has a few helpful (to me anyway) view resources; comments for
improvements are most welecome.

Have a good one,

Bill
