tooltip widgit not able to be attached to gfx element

[macasek@…]

The Tooltip Widget which ultimately uses dijit.placeOnScreenAroundElement(..) does not account for gfx element positioning.

In the placeOnScreenAroundElment method, which is used to place the Tooltip, the following lines:

var aroundNodeW = aroundNode.offsetWidth; //mb.w;
var aroundNodeH = aroundNode.offsetHeight; //mb.h;

return NaN for SVG elements (not able to test for VML) and as a result the Tooltip is never positioned on the visible screen. dojo.coords does not return correct position info.

A quick work around for this issue is to attach offsetWidth and offsetHeight properited to the gfx elements based on the generated translation matrix:

offsetWidth = matrix.dx + node.radius
offsetHeight = matrix.dy

Code Snippet

node.group = this.surface.createGroup();
node.group.getEventSource().id = node.name+"_group";		
node.circle = node.group.createCircle({r:node.radius, cx:0, cy:0}).setFill(node.gradient);
node.circle.getEventSource().id = node.name+"_circle";
node.text = node.group.createText({text:node.name, align:'middle'}).setFill("black");
node.text.getEventSource().id = node.name+"_text";
		
var matrix = dojox.gfx.matrix.translate(point[0], point[1]);
		
// HACK: gfx elements to not have the offset* set (or any other positioning) needed by dijit.Tooltip.
node.group.rawNode.offsetWidth = matrix.dx + node.radius;
node.group.rawNode.offsetHeight = matrix.dy;
node.circle.rawNode.offsetWidth = matrix.dx + node.radius;
node.circle.rawNode.offsetHeight = matrix.dy;
node.text.rawNode.offsetWidth = matrix.dx + node.radius;
node.text.rawNode.offsetHeight = matrix.dy;
// end HACK: gfx elements to not have the offset* set (or any other positioning) needed by dijit.Tooltip.
		
node.group.setTransform(matrix);
node.group.add(node.text).add(node.circle);
this.surface.add(node.group);

new dijit.Tooltip({label: "my tip!", connectId:[node.name+"_group"]});

Wow I am a fool, I totally put this in the WRONG trac! Sorry, please remove.
