Hi,
btw, thank you John Finlay for the answer on my last question.
In my quest of a GUI interfacing my small database application (I did
try OpenOffice Base and went mad after one hour :S ) I would like to
copy some behaviour of MS Access in my forms.
Say I have two (SQL) tables with two fields and one relation between
the two:
---------------- ----------------
| Table1 | | Table2 |
---------------- ----------------
| Field1 (int) |<---->| Field1 (int) |
| Field2 (str) | | Field2 (str) |
---------------- ----------------
Now in my PyGTK form of Table1 (a TreeView), when I display the
Field1 in the first column, I would like to have a ComboBox which
displays the text associated to the integer value of Table2 (i.e.
Table2.Field2) rather than the value directly. However, I still want
it stored as an integer in Table1.Field1.
How would you do this in an elegant manner ? Do I have to create my
own CellRenderer more generic than a CellRendererCombo ?
How do you want the db info displayed in the treeview?
I think of actually displaying the content of Table1 with Field1 in the
first column and Field2 in a second column. However, Field1 wouldn't be
displayed as an integer but as a string coming from Table2. In order to
modify the content of Field1, I would like the user to select a string
(of Table2.Field2) in a CellRendererCombo rather than an integer.
Are you planning on inserting the
table info into a liststore or generating it on the fly?
I thought of using two separate ListStore to store the content of each
table. I don't know if it is the best way but I want to alter the
information in the DB only when the user has finished his modifications
in the GUI.
