[reportlab-users] positionate flowable in frame ?!

[Andy Robinson]

Hi Tamer,

Some basic concepts:

You don't precisely position things in a frame.  If you want to
precisely position something (e.g. a table), then call wrap() to get
its size, and draw() to place it exactly where YOU want on the canvas.

Frames are supposed to consume from a list of content, moving
downwards automatically, and onto the next page, like a word
processor.  The frame, not you, decides where to position your
flowables.  Usually, just below the previous flowable.

Now for the details:  paragraphs are usually the full width of the
frame, so horizontal alignment of "the whole object" does not apply.
But for something with a smaller width, like a table, all flowables
have a property hAlign.  Tables also have a property 'colWidths'.  so
you can do

   myTable.colWidths = [100,50,50,50]  #units in points
   myTable.hAlign = 'CENTER'   #or 'LEFT' or 'RIGHT'

and it will be positioned accordingly.


You will also find it very helpful to read the RML examples and user
guide on our site.  It's a commercial product but the XML tags
correspond pretty much one-for-one to the underlying Python objects,
and it's well documented and full of visual examples, so you can see a
style you like and guess with 90% accuracy what Python properties you
need.

I hope this helps,


Andy
