A small script to display some elements.

|mainNode view title childNodes|

view := ROView new.

mainNode := (ROElement spriteOn: 'A Test Node') + ROBorder.

childNodes := (ROElement spritesOn: (1 to: 10)).

childNodes do: [:each | each + ROBorder].

mainNode addAll: (ROGridLayout on: childNodes).

view add: (ROVerticalLineLayout on: (mainNode)).

view open

Now, I would like to construct my ROGrid layout such that items per line are 3. However, there is no method in ROGridLayout that allows setting the line item count AND returns a collection of ROElements. So, I may propose the following code to be added on ROGridLayout (class-side):

on: aCollection withLineItemsCount: aBlock

| myLayout |

myLayout := self new gapSize: 5; lineItemsCount: aBlock.

myLayout applyOn: aCollection.

^ aCollection

let me know if it makes sense.
