Make use of signals to connect the selection in plot to the associated
table widget. Every time that the plot is updated from the Main Window
the table widget associated to the table or query is connected to the plot
and the previous widget is disconnected. This allows the selection of the
correct table widget.
Line selection methods moved to the Extended Table Widget to be used as
slots for this connection.
The destroyed signal is also connected for resetting the plot. This fixes
a crash that already existed before this PR, when closing a SQL tab while
the plot is still associated to the table results model.
When dragging and dropping a table from one instance of the application
to the other, the tree structure representing the database was broken.
We would show the 'Browsables' and 'All' nodes at the top level instead
of the child nodes of the 'All' node. This happened because after
dropping a table, we would reload the database structure and rebuild the
tree structure but didn't notify the tree view in the main window about
the update. This is fixed by this commit, so the main window's widgets
are always notified about the new tree structure.
See issue #1288.
Don't set the modified flag of the main database if we're attaching or
detaching another database since these actions don't alter the original
database.
See issue #1249.
That avoids overwriting existing record as reported in issue #1255.
This doesn't improve the underlying situation, that is inserting empty rows
before duplicating the content. But it is safer to not ignore the error in
the initial row insertion.
A new button is added to the Browse Data tab for saving the current display
of the table (current filter, sort column and display formats) as a new
view. This allows (specially for non advanced users) the creation of simple
views. It can be seen, either as a way of storing the current
filtering or as an easy way of creating views.
This reuses the query set in sqlitetablemodel, but the column aliases when
a display format is used has been changed from col%1 to the original column
names, i.e. format(`orig`) AS `orig`.
Find/Replace dialog does not block the main window.
Dialog reused, so checks changed by user are preserved.
The selection of the last occurrence in Find All and Replace All
is cleared, so all the occurrences have the same appearance.
A classic Find/Replace dialog including all the options provided
by the QScintilla editor. Additionally a "Replace All" and a
Find All" button are implemented. This complements issue #191
New shortcut in main window for opening the find/replace dialog
connected to the focused widget. Standard for Replace is Ctrl+H.
Consequently the shortcut for Copy with Headers is changed to
Ctrl+Shift+C (see issue #1058).
For SQL text widgets not embedded in the main window, the standard
shortcut cannot be enabled, otherwise it conflicts with the main
window. Therefore the shortcut Ctrl+Shift+H is enabled for all the
SQL widgets as fallback. A better solution would be desirable.
The user is now able of selecting a range of contiguous points in any of
the graphs of the plot, through rectangle selection or click in single
point. This selection triggers automatically the selection of the
corresponding lines in the browsed table. In this way the user can analyse
the plot in detail.
Two other minor improvements: spelling error fixed and the dummy column in
the plot selection table has now transparent foreground (intends to avoid
wondering of the user about what functionality provides this column).
The find operations in QScintilla are used for implementing a find frame
in the SQL Editor of the main window. A checkable tool button is added
in the SQL Editor toolbar for showing and hiding this frame.
There are check boxes for Whole Words, Case Sensitive and Regular
Expressions. The QScintilla facilities in the findFirst method are used
for the implementation.
The no collate function warning is triggered in a thread which is used
for loading data. However, the warning is a message box and GUI elements
can only be drawn in the main thread. So the old code would crash. This
is fixed here by jumping to the main thread for showing the message box.
With this commit the main window keeps track of the hidden columns and
re-hides them when the table is selected again. It also saves the hidden
status to the project file and restores it from there.
In the Execute SQL tab, move the button for saving the results of a
query as either a CSV file or a view from the bottom of the results view
to the toolbar at the top.
See issue #1122.
Similar to commit 44eb2d4f99 this commit
makes use of the backend code improvements introduced in commit
532fcd3f6b.
It adds support for database schemata other than "main" to the Browse
Data tab. With this it's possible again to browse and edit data of
temporary tables using the Browse Data tab. This time, however, they are
separated logically from "main" tables. So handling temporary tables
should be a lot less error prone now, plus it's easier to tell for the
user what tables goes in what schema.
This commit changes the project file format. There is some code included
which allows loading of project files in the old format. However,
project files generated using versions after this commit can't be loaded
by older versions of DB4S.
This commit removes the File -> Remote menu entirely. The only menu item
that was left was the Save to Remote item which is replaces by a button
in the remote dock.
The button is only enabled when a database file is opened and the user
has logged in using a certificate.
Clicking the button opens the same dialog and performs the same actions
as before. The only difference is that we don't use the first client
certificate - no matter which one it is - but instead use the client
certificate that was used for logging in.
This adds a new context menu option that allows unlocking views for
updating. This requires appropriate triggers to be in place and the user
to type in a column name that can be used as a 'primary key' for the
view. By default views are still locked from editing.
Inserting into and deleting from views isn't supported yet.
See issue #141.
This adds a local database to keep track of all the cloned databases.
For now we only use this information to prevent exactly the same
database being downloaded twice.
Move the network part of the automatic version check code into the
dbhub.io parts. While semantically this doesn't make a lot of sense it
simplifies the code a bit, reduces the size of the main window class,
and avoids duplication of code e.g. when introducing proxy support.
This adds a new dock to the main window that contains all the remote
functionality (or is supposed to contain it all in the future).
It also adds a directory browsing feature which allows you to browse
through the folders and files on the dbhub server.
By double clicking a database you can download and open it. The Open
Remote menu action isn't needed anymore and has been removed.
This also fixes an issue with pushing databases where, after sending the
file is completed, the save dialog was opened.
Note that this is still WIP and is far from polished.
Improve the Create Index dialog so that it allows creating as well as
editing indices.
Chenge the code for the main window to allow editing existing indices.
This cleans up the main window class a bit which was getting quite large
and a bit harder to maintain than necessary.
This commit also includes two minor fixes to the plot system:
- The plot widgets are now disabled when no database file is opened.
- The progress bar shown when fetching all data is now initialised with
the correct row numbers.
Other than that this commit should in theory not change any
functionality.
Change the layout of the preferences dialog a bit.
Remove the server selection combo box from the preferences dialog as it
will probably never be required. The way we do logins using certificates
kind of makes this obsolete, I think.
Restructure the whole remote code a little bit. Also add helper
functions here and there.
Show a list of our the CA certificates built into the application in the
preferences dialog. This list is read only of course but still
informative as it tells the user which sites are supported ny DB4S.
This adds some initial support for opening remote files. You can enter a
URL and DB4S will try to download the file. When successful you'll be
able to specify a place and name to save the file under, and after
saving it locally to disk it'll be opened just like any local database
file.
See the included TODO comments for missing features. Most notably
missing is the HTTPS and certificate handling code. Also any support
for storing the remote source of a database is lacking.
Store and restore the plot settings for each table - just like the
filter values or the column widths. This way you can have multiple
plots, one for each table.
Also, save these settings in the project files.
Make the reload shortcut (at the moment F5 and Ctrl+R) dependent on the
currently active tab. This way it always performs some meaningful task,
depending on the current context.
See issue #759.
We used to reload the database schema whenever it might have been
changed and the latest version was required. For example: when the user
switches to the Structure tab we need the current schema; so we just
reloaded it to be safe - it might have been changed in the Execute SQL
tab or wherever.
With this commit we don't reload the database schema anymore when an
up-to-date version is needed but instead when it was changed by the
application. So in the example above it's not reloaded at all anymore.
Only if and when the user would execute some structure changing SQL it
would be reloaded.
Benefits:
- Better performance
- State of the structure tree view isn't lost as frequently
- Structure tree view gets updated when changing the structure in the
Execute SQL tab
Downsides:
- Less error proof (testing!)
- No 'automatic' updates when the db is changed by an external
application.
Any suggestions welcome!
This adds some basic functionality for exporting JSON files by extending
the CSV export dialog. There is still a bit of work required for
fine-tuning the JSON export feature though. But a standard export of a
table s working well already.
See issue #688.
This hopefully helps to simplify and restructure the code. If it turns
out to make things only worse we can undo it. This *should* make no
changes for the user.
Prior to this PR, we've had the Edit Cell be available both in a "dock"
and "window" mode. Both at the same time. (!)
The "dock" mode already had tear off window functionality and was more
complete, whereas the "window" mode was buggy and didn't really add
anything new.
This PR removes the "window" version of the dock, and cleans up the
handling of "dock" mode, so there's just one Edit Cell dock now. It
can be torn off and used as a window, docked to the main UI (by double
clicking its title bar), and toggled on/off with Ctrl-E (Cmd-E on OSX).
