* Do process OnFocusChanged also while tree db refreshes, just avoid calling actEditObjectExecute.
* Make SelectedTable a property, rename to SelectedDbObj
* Remove calls to debug(), prefer LogSQL with lcDebug parameter
- display number of checked/total child nodes per option node
- display row count on "Data" option
- remove plus button from disabled option nodes, and do not check them
- code cosmetic
* Replace checkboxes, radio buttons and checklistbox by a VirtualTree using checkbox support
* Support selecting/deselecting single indexes
* Support foreign keys
* Place a SynMemo at the bottom in which the user can type an optional WHERE clause to filter incoming data. Fixes issue #2000.
* Move code for SQL generation into TTableColumn etc.
* Remove workaround for Unicode text to and from clipboard
* Fix writing/reading wrong encoded text into/from registry - no need to use Utf8Encode() any longer
* Implement TMySQLQuery.ColAsAnsi() for cases in which we read binary data.
* Removes TNT Unicode controls, which are no longer required. All VCL controls now have native Unicode support.
* Remove Delphi 11 packages, otherwise we would either need to keep TNT or break Unicode
* PngComponents update from Uwe Raabe on http://cc.embarcadero.com/Item/26127
* Adjust auto build process
* Since Delphi 2009, Strings are now UnicodeStrings, not AnsiStrings any longer. Fix a bunch of compiler errors which came along with this change.
TODO: Project should compile but give tons of compiler warnings.
* Instead, use separate SHOW commands for tables, functions, procedures and triggers
* Catch this chance to move these methods from main unit to mysql_connection, so they're accessible in a more generic way
* Additionally, introduce new classes TDBObject and TDBObjectList which provide a more generic way than TMySQLQuery to access these database objects.
Fixes issue #1529
* Move the auto refresh items to main menu (Tools) so it is usable in all places now, including the Data tab (which makes it working similar to tail -f).
* Keep only one TRegistry object in memory instead of creating a new one in each routine.
* Move out relevant functions and TRegistry object from main to helpers to make them usable globally.
- Fix cut labels using Vista font
- Fix wording in several places
- Normalize positions of controls, use default 8px margin to form edges
- Put a "Select / deselect all" checkbox below the field selection box
- Move registry related constants to const.inc and normalize their names
- Fixes bug #271 "F5 shortcut in database tree not working"
- Fullfills rfe #519 "Highlight selected item in tree view when focus is elsewhere"
- Fixes inconsistent expansion state of nodes after refreshing
- Fixes plus sign staying when a db node with 0 tables was selected
- Slightly enhances painting speed within the dbtree
- Removes temporary storage of a rightclicked node (DBRightClickSelectItem). VirtualTree handles its right clicked selection exactly like the left clicked one, which makes makes coding a bit cleaner as we can always use the selected item instead of hacking with the right and left clicked node. On the other side it removes a quite user friendly feature. Well, we can reimplement this feature later, though it's not user UNfriendly currently.
- Reasonably rename the StringList "OnlyDBs" to "DatabasesWanted" and "OnlyDBs2" to "Databases"
- Consequently use Mainform.GetRegValue() to read these values, an overloaded method with either Boolean, String or Integer result. These methods keep a global TRegistry object (regMain) open while the application runs, rather than creating a new one for each caller.
- Remove Mainform.SaveRegValue() which was used in one or two callers. Rather use a TRegistry object and do that by hand. There's no significant advantage in using a SaveRegValue method currently.
