Make it possible to drop database objects (i.e. SQL code) on the tree
view in the Database Structure tab. This is far from being perfect as of
now but enables you to drag and drop entire objects between databases.
Use a custom model for the tree view in the "Database Structure" tab in
the main window, i.e. change from a QTreeWidget to a QTreeView and do
all the item management stuff manually. This might add some code and
complexity but also offers some more flexibility for us.
Reduce the minimum width of two horizontal spacers, the one next to the
table drop down box and the one in the SQL log dock. This way the combo
boxes can take up a bit more space when the window is not that big.
Always use per pixel scrolling when scrolling in horizontal direction.
This changes the scrolling in the SqlExecutionArea and makes some
settings in the MainWindow dispensable.
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.
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...
removed uninteresting PRAGMA's for user
only set PRAGMA if value has changed
commit transaction before setting pragma with user warning
show the current PRAGMA value after setting
Remove two global variables storing the application short name which is
the same as the organisation name and the application icon which is only
used in one place.
Remove the copy and paste actions and slots from the main window code.
They have not been working for a very long time and seem to be rather
useless anyway.
Rename all slots starting with "on_" because Qt tries to auto-connect
them to signals of that name. And as those signals do not exist Qt
prints a warning for each of them after every program start.
Extend the code used to delete tables to also allow the deletion of
other objects in the data base.
Change the activation of the popup menu entries to activate the
associated action when a trigger, view or index is selected.
Do not scroll per item but per pixel when scrolling in the tree widget
in the DB structure tab of the main window. This makes scrolling much
more comfortable when the schema string includes line breaks.
Since quite a few problems are fixed by now and the program is moving
towards rudeimentary usability again it's time to add some new features
and problems!
This should let the user know that something's not working instead of
offering him a not working dialog and winding him up this way. That
should make the behaviour of the program much easier to understand.
Delete those two dialog, the only use of which is to make it possible to
select a table which is totally pointless because the user can do this
in the main window and would probably do so intuitively anyway.
