Hi,
How can I automatically position elements in the root edit part
depending on how big the canvas is?
For example - I want to position a child node about midway on the
vertical (left-aligned). Where do I put the code so that the child
node is repositioned correctly whenever the canvas is resized - and
how do I get the new size of the canvas?
Thanks
Murray

Hi Randy,
I'm still having some difficulty with this.
I'm not sure where to put the code to do the laying out of the child
elements. I tried putting it in the refreshVisuals() method of my
contents edit part - this method is called sometime shortly after the
contents editpart is added to the root - but it appears that at the
time it is called the Viewport figure has not been sized to the full
canvas (it shows a height of 32 and width of 64).
Can you advise as to what method in what class I should override to
put this laying out code in?
Thanks
Murray
