Hey all --
I have 2 related, seemingly pretty basic concepts that, if somebody
could take a minute to explain them, I'd be grateful.
1. "Subclassing a subclass of Window"
Basically, I have a window, ListWindow, which, depending on how its
properties are set, will display records from any of my MySQL tables,
in a ListBox. Double-clicking on a row will open another window in
which you can edit the record.
Now, though the layout of ListWindow is suitable for any table, the
layout of the editing window is table-specific. Just to get myself
going, I've just been creating new editing windows -- table1Window,
table2Window, etc. -- with different layouts and copy/pasting the
shared methods, properties, handlers, etc.
However, it seems silly and anti-OOP to have the same code over and
over, and it seemed like the obvious solution was to make a subclass
of Window, EditWindow, with all the shared methods, props, etc., and
then make it the super for table1Window, table2Window, etc. which
would have different layouts.
But RB won't let me set "EditWindow" as a super class. Any ideas?
----------------------------------------------------------------
2. "Programmatically choosing which EditWindow to open"
In ListWindow, I have code that looks at the MySQL table ListWindow
is using, and opens table1Window, table2Window, etc. accordingly.
Because it works, I was just using a Select Case:
dim w1 as table1Window
dim w2 as table2Window
...this goes on for a while
Case "table1"
create and load table1Window
Case "table2"
create and load table2Window
etc.
...anyway, it's clunky, I have to dim all the windows outside of the
control structure and it just LOOKS wrong. Is there a way for me to
do something more like:
(having stored a property in ListWindow called WhichWindowToOpen)
dim w as WhichWindowToOpen
w = new WhichWindowToOpen
w.LoadRecord, etc.
?
Thanks, very much, in advance,
Ian
