To change a shape parameters, say, a line, use:
line.setShape({x1: 0, y1: 0, x2: 20, y2: 20})
Too bad this isn’t present in any documentation that I could find!!!
BTW, gfx.Shape API is nowhere to be seen! It makes it really hard to code this way…
After getting a shape pointer, change its border color and width like this:
var shape = getShape(event);
shape.setStroke({color: "red", width: 2});
When getting a widget by id, I should use:
dojo.widget.byId(_id_)
Despite this being a rule, I came across the stupid behavior, just as follows:
<script>
container = dojo.byId("gfx_holder");
warning_container = dojo.widget.byId("upper_menu");
</script>
<html>
<div id="gfx_holder" dojoType="ContentPane" ...
<div id="upper_menu" dojoType="ContentPane" ...
</html>
</div></html></code>
container does not work if dojo.widget.byId is used.
warning_container does not work if dojo.byId is used.
So I need to remember to USE BOTH METHODS...
