* remove ParentFont flag from forms again (introduced in 9cdcd631454f6f9e999893ea89fcf502d994474c for #213). This just inherits from default Windows settings.
* instead, scale font size in InheritFont(), and move that to the new TExtForm class
* mark app with PerMonitorV2 support
* Introduce TAppSettings, created in dpr file
* Implement read and write methods, and replace callers of GetRegValue and MainReg.WriteInt/... with these
* Optimize read and write methods for avoiding redundant accesses to registry
* Auto-remove stored default settings from registry to avoid registry spam
* Replace synced MainForm.pref* variables with TAppSettings.Read* calls
* Move SetLocales call to dpr file
* Move MainForm.FDirname* variables to appropriate methods in helpers.pas
* Implement TQueryHistory.Create(SessionPath), reading its items within constructor
* Don't try to access a passed tree if it has been destroyed by some earlier event.
* Don't try to access registry in DoDisconnect after key has been closed.
* Now that DoDisconnect lives in FormDestroy it is save to call it slightly earlier, before registry has been closed. There should be no later paint events which will trigger random database queries.
* Load in OnBeforePaint, if the tree's tag is set to NOTLOADED
* Load 1,000 rows in one step, up to a maximum of 100,000 rows. Both values are customizable.
* Load next chunk when user presses PageDown on the last node, or, more explicitly, when user clicks "Next rows" button
* Should fix all AVs which seem to be a timing issue with loading data on demand.
* Fixes issue #1675, fixes issue #1580, fixes issue #1721, fixes issue #1734, fixes issue #972
* 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.
* 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.
- 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.
Additionally/Sideeffects:
- Fix vstFreeNode to delete the item from the array, not only free the item itself
- Change/Rename GetSelectedNodesFromVT to GetVTCaptions and give it the ability to return all captions, not only the selected. This function is very useful now and saves writing much redundant code.
A table with 500 columns needed 3 seconds to display in the TSortListView, now that takes less than a half second.
