[reportlab-users] Can a pagetemplate modify its frames?

[Roberto Alsina]

I am trying to implement a "smart page" PageTemplate which does things like 
adjust margins and show/hide headers and footers depending on the content.

Can I modify self.frames from a PageTemplate?

I tried this to implement a "gutter margin" with no visible effect:

    def beforePage(self,canv,doc):
        print self.frames[0].__dict__

        # Adjust gutter margins
        if doc.page%2: #Odd page
            gm=self.gm
        else: # Even page
            gm=-self.gm

        print gm

        for f in self.frames:
            f._x+=gm
            f._x1+=gm
            f._x2+=gm

The values change but the frame doesn't move :-)
