Text outside ShapeNode Outline

I have a set of icons that I load as shapes in a diagram, but the node.text is shown on top of/over the icon. How can I change the text position to be outside the shapenode outline, e.g. below the icon?

Thanks,

Guido

Set the shape's TextArea to a region outside the 0-100 range. Since the BPMN shapes have their text region below the outline, you could copy it from them. E.g. if you are using Rectangle nodes to display the icons, you can set Shapes.Rectangle.TextArea = Shapes.BpmnStartMessage.TextArea.

I hope that helps,
Stoyan

This approach causes an exception to be thrown when using a standard layout, such as the topological layout.  Even without the layout, the diagram throws an index-out-of-bounds exception when trying to draw.

I tried assigning to the global Shapes.Rectangle.TextArea, but that didn't do anything.  Then I tried it for an individual shape using myShape.Shape.TextArea and got the exception.

Can you be a bit more specific on the steps to get this to work?

Hi,

Try setting it before the shape is assigned to any nodes, e.g. at the start of the FormLoaded handler.

Otherwise you might have to loop over the nodes and reset their shapes (just set node.Shape = node.Shape) so that the nodes refresh some cached geometry objects they keep for their Shape.

I hope that helps,
Stoyan
