The #xSeparation is set to the space between buttons. </blockquote> Ok, I got your point. Thanks. I will try it. I used a different approach with a transparent morph to push the buttons to the left and the right. <pre> row addMorphUseAll: (WidgetMorph new borderWidth: 0; color: Color transparent). </pre> <blockquote type="cite" cite="mid:dd36cb626917e88d5a8eee1923004756@whidbey.com"> After requiring 'Morphic-Misc1', a Morph's menu allows to get edit panels for LayoutSpec and, if appropriate, a LayoutMorph. You can set the "push pins" to easily play with layout parameters to see what they do. </blockquote> I played with the edit panel yesterday on existing layout, I did not notice any effect. I should try again.
