Hello All,
I am trying to understand how to format numerical data in a Treeview.
All is well when using "{0:0.2g}".format for my Entry widgets. I would
like to format my Treeviews similarly. This is easy, I know, but I
haven't found the magical link on Google or in the PyGTK API docs yet.
The information I am displaying in the Treeview is being pulled from a
MySQL database. Below are the code snippets showing how I create the
Treemodel and load the Treemodel. Since I am loading my model "by row",
I can't apply the formatting to the individual fields. My intuition
tells me this is likely the only way I can accomplish what I want. But,
before I re-write my code, I wanted to ask if it is possible to do what
I want at all and what is the best way to do it.
Thanks in advance for any help the community may offer.
Andrew
