Hi Leo, I understand your email. As Doru has been saying, we need a way to specify where the nested elements should go when composing shapes. Currently I have unfortunately no solution. The approach you can do right now, is the one taken by all the GUI framework that I know: encapsulate the label and the container with its nested element. Here is an example that you can get inspiration from: -=-=-=-=-=-=-=-=-=-=-=-=-=-=-= | classes allClassElements v es enclosing label g1 back | classes := RTShape withAllSubclasses. allClassElements := OrderedCollection new. v := RTView new. classes do: [ :cls | es := RTBox elementsOn: cls methods. es @ RTPopup. back := (RTBox new color: Color blue) element. RTNest new layout: RTGridLayout new; on: back nest: es. enclosing := (RTBox new color: Color transparent) element. label := (RTLabel new text: #name) elementOn: cls. g1 := RTGroup withAll: { label . back }. RTNest new layout: RTVerticalLineLayout new alignCenter; on: enclosing nest: g1. enclosing @ RTDraggable. v add: enclosing. v add: back. v addAll: es. v add: label. allClassElements add: enclosing. ]. RTFlowLayout on: allClassElements. v -=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

I tried this but it is not working view := RTView new. container := (RTVerticalCompositeShape new shape1: RTLabel new; shape2: (RTBox new color: (Color blue alpha: 0.5))) elementOn: 'Container'. els := RTEllipse new elementsOn: (1 to: 16). view add: container; addAll: els. RTNest new layout: RTGridLayout; on: container nest: els. view @ RTDraggableView. view open As you can see the label is not move due to the resize of the box with the nest. I do not use TRConstraint because I will have several boxes and if I apply a layout on them the label is not calculate in the size so I do not think this is a solution but RTNest on RTVerticalCompositeShape is. -- Cheers, Leo Perard University of Lille 1 _______________________________________________ Moose-dev mailing list Moose-dev(a)iam.unibe.ch https://www.iam.unibe.ch/mailman/listinfo/moose-dev _______________________________________________ Moose-dev mailing list Moose-dev(a)iam.unibe.ch https://www.iam.unibe.ch/mailman/listinfo/moose-dev
