Make it possible to rename columns and change their types even when
editing an existing table. This requires a workaround to not use the
ALTER TABLE command which is not fully supported by SQLite.
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.
Reset the sorting of the table view in the browse tab when changing the
current table. This offers not just only a more plausible behaviour to
the user but also fixes a bug that would cause an empty table to be
shown when sorting e.g. column number 5 and then changing to a table
with just 2 columns.
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.
Change the design of DBBrowserDB to store all DB objects in one single
map instead of having one map for table, one for views, one for triggers
etc. This requires some changes in the entire program.
Show more details of views in the DB structure tab, i.e. the names of
the fields included in the view. Allow browsing views in the browse tab
and allow exporting views as CSV.
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.
Fix the caption of the edit field dialog to show the correct table name
when it is called by the modify field action in the popup menu or the
toolbar.
Also remove one more useless debug message.
