Trying db-aware combo boxes in Kexi

Hello, an initial working code for db-aware combo boxes have
been commited for 
Kexi in 1.6 branch. Since these are now hardcoded (i.e.
there's no designer 
for the feature yet), you need to have a tables and columns
with a given name.

Here's a minimal database (15KB) having 'cars' and
'persons' tables, where 
cars.owner is in realtionship to persons.id:

_test.kexi

To see and try the combobox, you can open 'cars' table and
look at "owner" column.

Hi,

From the screenshot I gather it does not use a real
combobox, as it looks 
quite different.
How well does this combobox listen to theming (different
widget themes), 
accessibility, color settings and RTL languages ?

How many items do you expect that this combobox shows? On
average.

Why I _knew_ you'll respond quickly? 
This cannot be a combo box, because the content is very
generic db table view 
(KexiTableView), read below.

First, all the Qt is not _native_ library, it just mimicks
the native 
behaviour (on systems where native makes sense). Nothing
special, so 
KexiTableView/combo box went the same way.

This is a popup behaving exactly in the same way (and
implemented similarly) 
to the QComboBox. It is implemented using KexiTableView, so
most questions go 
to this class in fact. Most of the bits that _can_ be
inherited from QStyle 
are already applied as defaults (colors, fonts, shortcuts).

Since there are style items for "table
view"-like widgets that QStyle/KDE 
lacks, I have an extension data type that delivers
appearance/behaviour, e.g. 
"highlight row"[bool], "highlight
color"[QColor], etc. More to come.

Regarding to RTL, KexiTableView itself is not very well
tested in this area. 
We're waiting for someone who can pay us with his
time/involvement. The stuff 
is prepared to handle RTL, just by adding special cases.
Moreover, 
Qt::AlignLeft means "right" for RTL in Qt4...

On average.

Columns? Sometimes it's 5. 2 on average.
Rows? Sometimes dozens, sometimes about 8 (so no scrollbar
is presented then)

I'd like to see an some usability analysis for topics like
this.
