I (an elderly retired old fashioned progranmmer - think Cobol !)
am trying again to use Dabo to build a small application to maintain a
directory of photos (used as source for updating Open Street Map).
I'm using using a simple Sqlite database table which
includes the fields
v_filename - the name of the image
v_path - the folder where the image is held
as well as GPS data on when & where the photo was taken.
I've used the PyCon2010 documentation ('Creating a Dabo Application From
Scratch')
to create a form to display the data from the table - this works fine
and I can move up and down quite happily)
At the foot of the form I have a dImage control where I wish to display
the photo.
This works OK when I set the Picture property to a test .jpeg and I have
determined that image can be set in the 'Update' method.
My problem is very, very simple - how to I access the contents of
earlier text boxes to generate the location of the photo.
Object Info :
v_filename is in 'dTextBox r0:c1 (dTextBox)'
v_path in 'dTextBox1 r:3,c1 (dTextBox)'
the code (for dImage)
"def update(self):
import os.path
x_file=self.Form.dTextBox.Value
x_path=self.Form.dTextBox1.Value
x_image=os.path.join(x_path,x_file)
self.Picture=x_image"
fails with
AttributeError: 'dForm_39286' object has no attribute 'dTextBox'
It's a simple problem but I don't think I've grasped how the various
parts of the app
ie UI, Bizobj can be accessed (ie bizobj from UI and changing UI seeting
from Bizobj)
