Yes that was my first idea before you integrate the composite shape. It is working but there is a lot of inconvenience like a transparent shape that the user don't know its existence, 4 elements (or group) whereas with composite shape there is only one element and a group etc...

I keep this solution but I prefer to wait until a better one will be found.

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 -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

Hi,

using Roassal2 I would like to get a box with some nested element on it and the box get a label above itself.

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.
