It seems you are asking for the scroll value before the layout has been calculated. (since the window hasn't received a fullbounds yet). | 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). "Recalculate bounds now for this example... not generally needed for normal code!" scroll fullBounds. "****" scroll hScrollbar value Is not normally an issue, as you can see from inspecting the scroller after being opened.

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!

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
