[Moose-dev] Re: Issue 831 in moose-technology: Rossal problem with nested node translation to left of 0@0

Comment #3 on issue 831 by google....(a)ben.coman.com.au: Rossal problem with nested node translation to left of 0@0 http://code.google.com/p/moose-technology/issues/detail?id=831 Just another example perhaps a bit quicker to follow. In the attachment, Image A is the reference being all translations in the positive direction for e11, e12 & e13. Image B is what I believe should be the result for e21, e22 & e23, where the relative orientation of e21 & e22 remains the same as e11 & e12. However the current results is Image C. Image D shows the result is different if the two translator lines for el23 & el22 are swapped in order. Whereas I think it would be good if the resulting layout was independent of the order that the translates are executed. I am trying to chase this down myself, and it seems to me that the culprit is in ROAdjustSizeNesting>>on: where a negative top left corner is relocated back to 0@0, but I need to do more to understand what is happening. cheers -ben -------------------- | paramNodeCount translator view outer1 outer2 el offset el11 el12 el13 el21 el22 el23 | paramNodeCount := 2. translator := ROLayoutTranslator default. view := ROView new @ RODraggable. outer1 := (ROElement spriteOn: ' outer1' ) + ROLabel . outer1 add: (el11 := (ROElement spriteOn: 11) + (ROLabel text: [ :my | my model asString, String crlf, my position asString ] ) @ RODraggable ). outer1 add: (el12 := (ROElement spriteOn: 12) + (ROLabel text: [ :my | my model asString, String crlf, my position asString ] ) @ RODraggable ). outer1 add: (el13 := (ROElement spriteOn: 13) + (ROLabel text: [ :my | my model asString, String crlf, my position asString ] ) @ RODraggable ). outer2 := (ROElement spriteOn: ' outer2' ) + ROLabel . outer2 add: (el21 := (ROElement spriteOn: 21) + (ROLabel text: [ :my | my model asString, String crlf, my position asString ] ) @ RODraggable ). outer2 add: (el22 := (ROElement spriteOn: 22) + (ROLabel text: [ :my | my model asString, String crlf, my position asString ] ) @ RODraggable ). outer2 add: (el23 := (ROElement spriteOn: 23) + (ROLabel text: [ :my | my model asString, String crlf, my position asString ] ) @ RODraggable ).
