Also load the default extensions when creating a new database.
When opening a database load the extensions before reading the structure
and the pragmas because the extensions could affect those.
Add a row of line edits between the table header and the actual content
of the table in the browse tab. Show one input widget per table column
in this row.
Add a live search which hides any table rows which do not fit to the
current filter settings.
Why add this to the parital-data-fetch branch? Because this is an
attempt to get rid of the find dialog which is broken again and not even
worth fixing. Also there is not much to break in this branch at the
moment ;)
Change the way sorting is done to correctly sort all data even if it
hasn't been loaded completely yet.
Fix the navigation label and buttons by showing the correct information
again and fixing the validator of the input field.
Log all SQL statements executed from within the SqliteTableModel.
Silence a few warnings.
Fix empty rows being shown in the main window when changing to a table
with less rows than the old one.
Add sorting in the browse tab again.
Do some minor clean ups.
Now it should always be possible to add a new record,
no matter how the table is defined or what the new data default is.
The default new data setting will be removed in the next commit.
Rewrite the import SQL code using a similar method to the one used in
executeQuery(). This makes the code much easier to read and removes the
last remnants of that C code stolen from some demo application.
Read and write the settings only from the preferences dialog.
Remove all the copies of some settings which were stored in nearly every
dialog class individually.
Simplify the settings dialog code by removing all those not really
needed slots.
Store the data of a DB cell in a QByteArray, i.e. a binary data type,
instead of putting it in a QString, thus converting it to a UTF8 string.
Rewrite the reading and writing of DB cells to correctly handle binary
data containing 0x00 bytes.
Change the edit dialog to actually do all the data checks etc. on a
currently invisible QHexEdit widget instead of a QTextEdit.
All these changes combined make it possible to actually store binary
data without it being corrupted. You can for example import pictures
now, export them and actually open the exported file. So this is an
improvement.
Fix the selection of entire columns in the browse tab table view. Even
when selecting multiple columns the data would be re-sorted instead of
selected; this is changed now.
Rewrite some code to use a QTableView widget instead of a QTableWidget
in the browse tab of the main window, or more presicely in the new
extended table widget class. This way the widget and the data model are
separated which on the one hand means a bit more work on our side but on
the other hand also gives us a bit more flexibility. And more
importantly at the moment: This means both, the browse tab and the sql
tab, use a table view now - that's going to be helpful for the next
commit...
