[reportlab-users] positionate flowable in frame ?!

[Tamer Higazi]

Hi!

I have red the Reportlab Guide, and I am not getting smart howto
positionate Flowables in a frame.
I have created a table, now I want to positionate the table to be
aligned right, but don't know how.

Is there a way to positionate flowables in a frame defining this with
the X,Y position ?!

And beside this proble, can somebody tell me how to set the cell's width ?!

Thanks for your support....

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

Thank you very much.

Now I start to get the concept.
