This shows a short text in the Remote dock when no certificates are
configured yet. This text contains links to the dbhub.io page and gives
at least some information on the overall process. As soon as the first
certificate is imported, the old view is shown instead.
This adds a label to the status bar which becomes visible whenever the
database is busy. It also specifies the currently running action. Also
add a button which allows you to cancel this action at the next
opportunity.
Note that this doesn't work for the Execute SQL tab yet which requires
some more rewriting of the code there.
This commit changes the project file format (and some internal data
structures) to support multiple sort columns in the Browse Data tab.
Note that this does not add actual support for multiple sort columns,
it's just a preparation for that.
After setting a filter, the user can select from the context menu in the
filter line a new option "Use for Conditional Format", that assigns
automatically a colour to the background of cells fulfilling that
condition.
The formatting is preserved after the user has removed the filter. Several
conditional formats can be successively added to a column using different
filters.
The conditional formats of a column can be cleared when the filter is empty
selecting "Clear All Conditional Formats" from the filter line context
menu.
The conditional formats are saved and loaded in project files as other
browse table settings.
A new class Palette has been added for reusing the automatic colour
assignment of the Plot Dock. It takes into account the theme kind of the
application (dark, light) for the colour selection.
A new class CondFormat for using the conditional formatting settings from
several classes. The conversion of a filter string from our format to an
SQL condition has been moved here for reuse in filters and conditional
formatting.
Whether the conditional format applies is resolved by SQLite, so filters
and conditional formats give the same exact results.
Code for getting a pragma value has been reused for getting the condition
result, and consequently renamed to selectSingleCell.
Possible future improvement:
- New dialog for editing the conditional formatting (at least colour and
application order of conditions, but maybe too: adding new conditions and
editing the condition itself).
New action and button for printing the database structure.
The data in the Database Structure tree widget is converted to HTML and set
in a document that can then be printed, opening the dialog as done for
other components.
Pragmas integrity_check, quick_check, foreign_key_check and optimize are
integrated in the Tools menu. The actions open a confirmation dialog
(with Help button that opens the corresponding reference page in
sqlite.org) and, after confirmation, opens a new SQL editor tab and runs
there the pragma, showing the possible results.
Sender in executeQuery is null in this case, so a check is added.
Added accelerator to Tools menu entry, which lacked one.
Add printing support for QScintilla widgets (SQL, JSON and XML). It can be
access through the contextual menu, shortcut (Ctrl+P) or (in the case of
the "Execute SQL" tab) from a button in the toolbar.
Ctrl+P was previously assigned to Plot Dock since
63c338c359 but, as it was foreseen in that
commit, it should be assign to print is ever supported. This change must
be mentioned in release notes.
First part of printing support. See issue #1525.
New entry under Help menu for requesting issues with the same template
used for a New Issue inside GitHub.
The "Bug Report..." entry has also been updated for adding the
corresponding template body.
Separators added in Help menu, since there are currently several different
options.
See related issue #1497
Two new options editable from a new context menu of the dock:
- Drag & Drop Qualified Names: add table name to fields and schema name
to other objects (except for "main" schema)
- Drag & Drop Enquoted Names: whether to surround the identifiers by the
configured quoting characters for identifiers.
Support for dragging & dropping of attached databases names.
Add "." as separator for multiple dropped objects other than fields (since
they are not usually used in SQL as a list). This allows to compose
qualified names by dropping the parent and the child items together. This
is only generally useful when the "Qualified Names" option is disabled.
See related issue #1433
In the Preferences dialog we allow the user to configure a list of
SQLite extensions which should be loaded whenever a new database file is
create or an existing database file is loaded. This commit changes the
order of actions after creating or opening a file so that the extensions
are loaded significantly earlier. This way they are already loaded for
most of the time during the process.
This fixes some subtle bugs. One of the more prominent ones was
triggered when there is a view which uses some function which is
defined in such an extension. After loading the file, parsing would fail
and you couldn't see the fields of the view. Browsing it would work but
trying to edit the display format crashed the application.
* Issue #530: constraints on table prevents new record being added
This adds a new dialog for adding records to a table. The current approach
is broken for several cases where foreign keys and check constraints are
impeding the insertion of an empty record. With the dialog, the user can
inspect the constraints (tooltip) and type of fields and add values
consistent with the requirements. The data is only inserted when the user
presses the Save button.
The dialog is modelled after the Edit Table or Edit Index dialog. An upper
frame allows entering the data using widgets. The lower frame previews the
SQL statement that will be used.
The old approach for adding records is still accessible pressing Tab on
the last cell of the table.
* Fix build problem introduced in previous commit on this branch
* Dialog as fallback for failure after empty row insertion and read only text
The insertion of an empty row is always tried. When it fails due to
constraints and foreign keys, the Add Record Dialog is open so the user
can enter values for the new record considering the constraints.
When the table has not constraints, or the row insertion provides valid
values, the user is still able to insert rows using the simple approach.
SQL preview in dialog is now read-only.
* Visual improvements for the Add Record dialog
QLineEdit as item delegate for the value, so it is more visible that we
are supposed to edit the value.
Remove last end-of-line in tool-tip.
* Improvements in the "Add Record" dialog
Display of NULL values using DisplayRole (no focus) or place holder text
(when focus).
Set value to NULL through a context menu and shortcut in the value line
edit.
Take text type affinity into account for quoting or not entered numbers.
New isType and affinity functions in sqlitetypes.
Clarify wording of constraints in tooltip for value. Added the same tooltip
for the type.
Escape quotes inside string values.
Removed unused parameters warnings.
Other wording or code improvements based on the pull-request review: #1477.
* User access to the Add Record dialog
The Add Record dialog is now accessible for the user. The New Record button
is converted to a QToolButton and a new pop-up menu is added to it for
invoking the in-line table insertion (New Record) or the Add Record dialog
(Insert Values...). What's This information for the button updated.
This is required for Qt version < 5.10. For Qt versions >= 5.10 the
unhiding of all columns before rehiding the desired ones does nothing
because there the table view doesn't store its state anymore. And when
it does nothing we don't change the state of our view settings which in
turn triggers the mentioned problem.
See issue #1475.
We have already fixed the rowid column from appearing after almost every
action in the Browse Data tab, for example in commit
39302f5b60.
This didn't fix every issue related to this problem though. Hidden
columns are shown too and modified column widths are reset. Also this
happens for different actions, for example the column widths are also
reset when sorting the view or when changing the filters. All these
problems are hopefully fixed by this commit.
See issue #1475.
* Allow "getting" and setting case_sensitive_like pragma
In order to allow case insensitive filtering, the pragma
case_sensitive_like is added to the GUI. Given that this pragma cannot be
read, a special SELECT request is made in DBBrowserDB::getPragma for
inferring its value.
See issue #1489.
* Warning in the pragma case_sensitive_like
This pragma has some peculiarities, so it is convenient to warn the user
about it through a tool-tip in the value.
Add a new menu option for opening an in-memory database. When working on
an in-memory database some menu options are disabled because they only
make sense when the database is also written to disk. I have left the
Write Changes button enabled though because for some actions the current
transaction needs to be committed - even though it's only committed to
memory then.
See issues #335 and #1492.
A popup menu has been added in the "Open Database" button. A normal click
selects the "Open Database..." action as before. A delayed click opens the
popup menu for selecting either the "Open Database..." action or the
"Open Database Read Only..." action.
Improve the enabling and disabling code for the insert and delete record
buttons in the Browse Data tab. With this the buttons should be enabled
if and only if they can actually be used. The commit also makes the code
easier to read because the final state of the buttons don't depend on
the call order of the involved functions anymore. Instead there is only
one function now which enables and disables them.
This also fixes one TODO in the multithreading patch.
If a view has been unlocked for editing by specifiying a pseudo primary
key, with this commit you can now delete records from the view if an
appropriate trigger exists.
See issue #141.
A new option is added to the Browse Data tab toolbar for exporting the data
of the browsed table as currently displayed (after filters, display formats
and order column) to a CSV file. This is done in coherence to the same
popup options in the SQL tab for execution results.
See issue #1402
Browse data table settings are now saved in the project files using a pure
tagged XML format. This would make easier the generation of our project
files by external tools or direct human edition of the project files.
Compatibility with the older format is preserved in the loading. Previous
software versions have been tested with the new format, and they are also
able to load the new project files ignoring these new tags.
See related issue #1306
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.
