Ok. What is the order of operations one should use to define
a grid, and
then a gridtablebase?
My dataset is going to change many times at runtime.
Here is the larger picture:
My application is a time tracking application, working like
a punch
clock. So projectIDs, TimeIn, TimeOut,
and descriptions can get into the hundreds per week and
defiantly per month.
I have an Sqlite3 database with Sequel as the abstraction
layer
retrieving the dataset.
I have completed the "data entry" portion of my
project. In order for
that information to be useful,
I need to be able to view it, etc. I am passing Sequel
datasets to my
derived wxGridTableBase class.
The nature of my dataset is that I would like to adjust the
dataset on
an event driven basis.
For example button(s) to switch views between:
week summary of hours
month summary of hours
daily summary of hours
etc..
All ordered by projectID. I can handle the sql queries. But
I have yet
to even be able to successfully link the wxGrid to the
wxGridTableBase.
I have scoured forums and the wxRuby docs, sample code
(BigDemo,
etc...), and asked in #wxruby. Google returns results in
wxPython, but
that doesn't help me.
I guess I just don't know what I'm doing with it yet.
To sum up:
1) What is the best practice or order of operations for
defining a
wxGrid and then linking it to a wxGridTableBase?
2) Is the linking in #1 possible to do on a runtime
event-driven basis?
3) Is there any wxRuby demo code anywhere? Or where can I
find more
ruby/wxruby 'centric documentation on this class?
