Hi Gary,
Did you publish the changes to GeneralScrollPane somewhere?
Cheers,

It seems you are asking for the scroll value before the layout has been

(since the window hasn't received a fullbounds yet).

scroll fullBounds.

scroll hScrollbar value
Is not normally an issue, as you can see from inspecting the scroller
after being opened.

Hi Gary,
I would like to implement a Finder-like behavior the GeneralScrollPane.
For this, I would need a way to control the scrolling so that every time I
add a new morph, the scroller scrolls (similar to
ScrollBar>>animateValue:duration: from OB).
The problem seems to be that the scrollbar value is not updated when I add
a new morph. Take a look at the code below. The result of the horizontal
scrollbar value at the end is 1.0, while it should be lower. Am I doing
something wrong, or is this a problem?
| m scroll |
m := PanelMorph new.
m
hResizing: #shrinkWrap;
vResizing: #spaceFill;
changeTableLayout;
listDirection: #leftToRight;
m addMorphBack: (Morph new
minWidth: 100;
hResizing: #shrinkWrap;
vResizing: #spaceFill).
scroll := GeneralScrollPane new
changeScrollerTableLayout;
scrollTarget: m.
scroll openInWindow.
scroll hScrollbar setValue: 1.0.
m addMorphBack: (Morph new
minWidth: 100;
hResizing: #shrinkWrap;
vResizing: #spaceFill).
scroll hScrollbar value
==> 1.0
Cheers,
Doru

A slight revision as this has highlighted an edge case in the original

as to when scrollbars are needed...

Excellent!
I tried the example and it works well. I will work with it in the
following days.

Hi Gary,
Thanks for the reply.
So, what would be required for scrollbars to work with spaceFill? I
would really need this feature, but I do not know how to go about it.
Could you or anyone else provide some hints? Of course code would be
even better. But at this moment hi ts would be helpful, too :)
Cheers,
Doru

Hi Doru,
#spaceFill constraints are typically only used by table layouts.
ScrollPane is designed for fixed size contents, at present.
Might be nice to extend it to honour any #spaceFill of its single
target morph.
This would simplify usage of scrollers quite a bit!

Subject: [Pharo-project] aligning morphs
Hi,
I would need help with understanding the magic behind alignment in
Morphic.
Take the example from below. Could anyone help me with what I should
do to have the morph stretch all the way horizontally?
| scroll window morph |
scroll := ScrollPane new.
scroll
fillStyle: (SolidFillStyle color: Color blue);
vResizing: #spaceFill;
hResizing: #spaceFill.
morph := PanelMorph new.
morph
fillStyle: (SolidFillStyle color: Color yellow);
changeTableLayout;
listDirection: #topToBottom;
vResizing: #shrinkWrap;
hResizing: #spaceFill;
layoutInset: 10.
morph addMorphBack: (SimpleButtonMorph new width: 200; height: 200).
scroll scroller addMorph: morph.
window := SystemWindow new.
window addMorph: scroll fullFrame: (LayoutFrame fractions: (0 @ 0
corner: 1 @ 1)).
window openInWorld
Cheers,
Doru
