[news.eclipse.tools.gef] Re: Extending FlowFigure

["Randy Hudson" <none@xxxxxxxxxx>]

You want to create a wrapper flow figure capable of wrapping any generic
figure.

This shouldn't be hard.  Create a flowwrapper which when it lays out,
constructs a box with the desired width and height for the normal inner
figure.  If you want the figure to fill up the containing block, you can
request a newline, then get the amount of available space on the newline,
and use that as the box's width.  Then add the box to the current line, and
endline again.  On postlayout, your box will be adjusted (although probably
it won't move since it fills block width), then you just reposition the
wrapped figure to be inside the box.
