Within Roassal I need to have a svg shape that knows
about a path.
Currently I do not make use of Athens to draw the SVG, I simply use Athens to draw lines.
But in roassal you do not have the concept of a polylines?
Ok I saw that SVGPath are not polyline as I originally thought. NOw
I do not get why you want to pollute Roassal with SVG names.
If you introduce the notion of Path why don;t you do it independent of SVG
because SVG is one way to represent path.
Within Roassal I can define any SVG path as a shape.
For example:
view add: (ROSVGPath path: 'M10,10 L30,30') element
Why this should not be at the level of Roassal? If I want to define a box, I would simply
do
view add: (ROBox new extent: 30 @ 20) element
Because I think that as a user I do not want to if my code works on svg or another
external format.
It follows the same pattern no?
Yes but this is different because ROBox is a roassal box not an svg or another format.
If tomorrow you get a pdf reader and access a library of pdf library. Do you want your
reader to
have ROPDFBox?
in SVG you also have
Rectangle <rect>
Circle <circle>
Ellipse <ellipse>
Line <line>
Polyline <polyline>
Polygon <polygon>
Path <path>
So I imagine (and hope) that you will not introduce ROSVGRectangle ROSVGLine
ROSVGCircle?
So why introducing ROSVGPath

I see that you have a loooot of fun.
Now I have the impression that in the future version you should not expose ROSVGPath and
others
because there are at the importer level not Roassal. So why do you need to wrap them.
If there is something missing in SVGPath what is it?

Hi!
I had fun understanding how countries may be described using SVG.
Here is a first shoot:
<Screen Shot 2013-11-16 at 5.36.21 PM.png>
Moving the mouse above a country name highlight the country. You can now rehearse your
geography.
The complete source code of this example is:
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
| view element nameComponent label |
view := ROView new.
ROSVGPath countries do: [ :k |
element := (ROSVGPath path: (ROSVGPath perform: k)) elementOn: k.
view add: element.
].
nameComponent := ROElement new.
ROSVGPath countries do: [ :k |
label := ROLabel elementOn: k asString.
label @ ROLightlyHighlightable.
label on: ROMouseEnter do: [ :event | ROBlink highlight: (view elementFromModel: event
model asSymbol) ].
label on: ROMouseLeave do: [ :event | ROBlink unhighlight: (view elementFromModel: event
model asSymbol) ].
nameComponent add: label.
].
ROGridLayout new
gapSize: -3;
lineItemsCount: 15;
on: nameComponent elements.
view add: nameComponent.
nameComponent translateTo: 0 @ 400.
view openInWindowSized: 1000 @ 700
