* Fix#2427
* Changed the openUrl() function to use a QUrl object, which has the appropriate scheme set.
* Preview widget now passes url handling back to DatabaseWidget
The Database, DatabaseWidget, and DatabaseTabWidget classes share many responsibilities in inconsistent ways resulting in impenetrable and unmaintainable code and a diverse set of bugs and architecture restrictions. This patch reworks the architecture, responsibilities of, and dependencies between these classes.
The core changes are:
* Move loading and saving logic from widgets into the Database class
* Get rid of the DatabaseManagerStruct and move all the information contained in it into the Database
* Let database objects keep track of modifications and dirty/clean state instead of handing this to external widgets
* Move GUI interactions for loading and saving from the DatabaseTabWidget into the DatabaseWidget (resolves#2494 as a side-effect)
* Heavily clean up DatabaseTabWidget and degrade it to a slightly glorified QTabWidget
* Use QSharedPointers for all Database objects
* Remove the modifiedImmediate signal and replace it with a markAsModified() method
* Implement proper tabName() method instead of reading back titles from GUI widgets (resolves#1389 and its duplicates #2146#855)
* Fix unwanted AES-KDF downgrade if database uses Argon2 and has CustomData
* Improve code
This patch is also the first major step towards solving issues #476 and #2322.
* Cleanup entry change notification with entryview focus in/out
* Change Open URL shortcut to CTRL+SHIFT+U to conform with an "action"
including SHIFT
* Change Copy URL shortcut to CTRL+U to conform with "copy" without SHIFT
* Entry specific toolbar and menu items are disabled unless the entry
row has focus (prevents unintended actions)
* Reword security setting for password visibility in entry edit view
* Add shortcut to hide/unhide usernames (CTRL+SHIFT+B)
* Organize entry menu
* Fix#1588 - show keyboard shortcuts in context menu
* Fix#2403 - Change auto-type shortcut to CTRL + SHIFT + V
* Fix#2096 - Add (CTRL+F) to search bar background
* Fix#2031 & Fix#2266 - add shortcut to hide/unhide passwords (CTRL+SHIFT+C)
* Fix#2166 - Add reveal password button to entry preview
The {group,entry}CloseButton QToolButton, had the "checkable" property set.
This caused it to act like a toggle flip flop instead of a momentary push
button. After removing that property, the signal it was changed to use
was clicked() instead of toggled(bool). Trigger upon click is
consistent with the rest of the UI's momentary buttons.
Rename UI elements involved with the bottom preview panel to use the
terminology "entry preview panel" instead of "details view" or "preview
panel". Change all associated variables, widgets, and classes to
reference EntryPreviewPanel. Create Config::upgrade() function and
deprecation mapping to help rename/remove previous config settings in a
clean manner.
Fixes#2327
